S-LOG2 SUCKS!! This is how to FIX IT. (Sony SLOG2 Settings)
Вставка
- Опубліковано 24 чер 2024
- I've tried it all: "How to expose for slog2", "sony slog2 settings", "slog2 color grading". And nothing ever made it work. UNTIL NOW! I finally figured out how to fix my sony slog2 settings so that I can get good looking images without so much hassle.
The issue comes down to the files you get from the sony cameras, 8 bit 4:2:0 at 100mbps does not leave a lot of room to push around colors. So every time I would try to grade sony slog2 footage, it would just fall apart with blotchy gross areas. But with a small tweak to my settings, I was able to finally find a way to enjoy working with slog-2 footage.

**A little disclaimer before you comment** A lot of the explanations in this video are very simplified for the sake of getting to the point and being a bit more accessible to beginners (who a lot of my audience are). I do understand that S-LOG and S-Gamut are not just decreasing contrast and saturation (I tried to make that clear at 5:48). I have tried overexposing for 2 stops, I've tried several different LUTS designed to correct/convert S-LOG/S-GAMUT to REC709 (like the ones I showed in the video and more). Unfortunately, even with those tools, the problems still persisted or new ones arose. However, when I applied this fix (increasing the saturation in S-LOG/S-GAMUT in camera) and then applied those same correction/conversion LUTS. The problem was significantly reduced and sometimes eliminated. My belief is that the problem is not actually S-LOG but the sony codec and bit rate issue. I know I titled it "S-LOG2 Sucks", but I think it probably only sucks at 8 bit 4:2:0 100mbps and as soon as Sony gives us 10 bit 4:2:2... this whole fix will probably be unnecessary. I hope that clears things up for those of you who were about to be like "THIS IDIOT HAS NO IDEA WHAT HE'S TALKING ABOUT"
Okay bye bye!
Dunna Did It
Would it be better if you record externally with 8 Bit 4:2:2 ? Or is 10 Bit 4:2:2 the only option?
That’s actually the next test! After I began my testing, I bought the Ninja V so I didn’t include that in this video (also, it would have made it very long and most people don’t have the ninja v) but I’m gonna be doing more testing with the ninja and 8 bit 4:2:2
Awesome! Please Let me know if it works👍
Yep, that is exactly the problem. My ancient BMPCC shoots 1080p, but full cRAW or Prores. Its far easier to grade in post than the A6xxx. Not because it has better slog but because there is just so much information in the underlying files. Lack of aggressive chroma subsampling plus decent bit rate/depth work wonders! The fix in the A6xxx is to put more information in the files via a hack - shoot to the right and boost the color.
Kinda kills some of the advantages of s-log but thats the only way with 8 bit and the subsampling Sony use in these models.
Thats actually a really nice idea...slog was never designed for highly compressed 8bit 100mbit Footage in the first place, so the artefacts are to be expected, as h264/5 throws away mostly color in areas that have little differentiation in them esp. in the lower exposed parts of an image. That ofc mostly affects slog 2 and particularly skintones where smooth gradients are very important. Thanks for this nice idea!
Btw: Filmconvert is another way to make sony slog 2 look really good! Its really good with less then ideal footage, can cover up a lot of things and make the image more „filmic“ if you will... :)
Try this instead: set Gamma to SLOG-2 but change the Color Mode to ITU709 Matrix (rather than S-Gamut). Problem solved, colors are sweet with no weird tint, and can be pushed in any direction without that blotchy stuff. Leave Saturation at 0, in addition to way better color mapping the ITU mode adds just enough Sat to set a solid baseline that can go anywhere.
Caleb from DSLR Video Shooter taught me that
Thanks. I'm going to try your settings. I'm shooting some test night scenes tonight. I'm curious how SLog2 will handle it.
@@AllThingsFilm1 How was it?
THIS IS THE RIGHT WAY ! THE TUTORIAL IS COMPLETE WASTE IF YOU ARE USING APSC CAM
Thank you, I should give that a try. Also, do you have any recommendations for the other settings? (Black level, color depth etc.)
I've been looking for this video for 3 years, I've been avoiding slog for this exact reason. 💯 % subscribing.
BRAVO dude. I cannot describe how this has been helpful. Such a simple approach to the problem you had and what to do to fix it. I like it
It's not perfect but it definitely helps!
I was looking for this problem on the whole web. Thank you so much!
This is the first time color profiles has made sense. Thank you for explaining this in normal human terms! 😁😁
So glad to hear that it was helpful Curtis!
Hi man, I loved this video. It is so to-the-point and easy to understand for beginners. Simplifying something for others is the hardest thing. And explaining it practically is what everyone wants. Thanks so much for doing this. Am subscribing...yayyyyy :)
I know this is an older video now but like you said in the video, low contrast and saturation is an over simplification of what slog is. With that in mind, correcting slog is not as simple as boosting saturation and contrast. You need to apply a rec709 lut to correct that because it is doing more "scientific" corrections than just boosting those two things. The outcome of the rec709 lut looks like it's just cranking up saturation and contrast but it is doing it in the "proper" way. BUT in the end I think you're correct with saying that a camera with 8bit color just isn't meant to have that much flexibility in correcting/grading. So yeah just shoot a flat profile that's not log and I think you'll have more options in post.
WOOOAH this worked! Tried it in S-Log3 as well, works there too. I can't tell you how great this is, man. Instant subscribe from me! This was the MAIN reason I try not to use any of the S-Logs on my Sony because of these botchy artifacts. But this setting with S-Log2 fixes some other color artifacts as well within gradients in darker areas. Of course, I see see the 8-bit banding rolloff, but without the color artifacts it's actually not bad and is useable. My workaround used to be applying the HSL secondary controls in Premiere Pro and just selecting the botches, reducing saturation and matching the color to the rest of the skin, but that is time-consuming. As of now, it seems that I won't have to do that. One of the most valuable UA-cam videos I've watched in a long time LOL. Thanks for that!
Thanks a lot für sharing. In fact i also struggled filming with Slog2. I changed to film in HLG3 (Details -5).But your explanation definitely helps me to go back to S-Log to film in low light with S-log. Thank you so much!
Another great video from Dunna. Good info to tuck away if I ever get back to owning a Sony camera.
Thanks dude!!
Yes! You are the winner!!!! I tried 7 different UA-camrs colour profiles and you was right! For some reason all of them resulted in horrible footage with very difficult ways to be adjusted. Your profile is simply applying the rec709, turn saturation down a bit and job done! Thank you so much! And i also tried cine4 and hlsg(if I’m not wrong) and for some reasons my footage was over exposed (probably it needed very high ISO). But yeah yours was test n.3 I made and if absolutely perfect! Thank you so much!😊😊😊
What do i win? I like being a winner!!!
Clever way to deal with this annoying issue! Thank you! Can't wait to try it. Subscribed to your channel.
Nice video man, it was very simple and helpful. I love it!!
Thanks so much!!
tested on my sony rx 100 V and it is perfect!!!! tested it in resolve . Slog2 Sgamut saturation to +32 camera setting is great handling the lack of saturation issue in such a poor codec. I dial saturation down to 30 in resolve and now i can actually play with the footage without fear of braking it too soon and results are amazing ether playing with your own grades or using luts, no more fear of using full power of slog2. THANKS DUDE!!!
Funnily enough I ended up doing the same thing but I was a bit more conservative with the saturation in camera. Glad to see I'm not the only one with this problem! Thanks for your help.
Haha I just go all out! I’ve heard some people say that they’ve had issues with colors clipping if they go all the way like this but I haven’t run into it
I'm am SO glad youtube reccomended me this video!! i've had exactlly the same issues with my a6300 and even tho i understood all the issue with not having 10-bit color or 4:2:2, there are plenty of people that use it and report no problems (like you said). One of the things i found out on my experiments, that you didn't metion and can maybe try is that by adjusting the contrast using CURVES instead of the slider, i had WAY more control over the "blockyness" and separation of colors (to the point where many times i got rid of it)! it must have something to do with luminance values of colors being torn apart by the codec and enhanced by the contrast slider or the luts, but i'm not sure.
Now i'm gonna try your solution, and maybe i will finally have peace using it, so thank you ❤ you just earned one more subscription.
Nice! Great suggestion!
OMG thank you so much. That's what i have been struggling for long assssss time!. your my savior.
Use S-LOG is bright settings like broad daylight, use a "Cine" profile for dark settings.
cine 4 to be precise.
HLG or standard profile is better for low light.
that´s true... as in dark set you don´t need to dinamic range , slog has not sense then.
@@yanccoliphotofilms1855 i think trues, because what detail in low light when on lighting, and we want dynamic range
just use cine4 for everything, slog2/slog3 is just always grainy, get a F1.4 to F2.8 lens and film with 100iso and you get great quality, crank up the sharpness to +5 with 4K and +10 with 1080 120/100fps, just works trust me, ive been using slog 2 for almost 2 years and i just dont get the same quality. because of the iso.
I literally just redid your test and came to the exact same result (on an a7iii !). It kinda makes sense in theory. now, there might be some camera pro out there pointing out that some other incamera settings are completely wrong for shooting Slog (my guess is it has to do with colour mode, conversion or import settings) but it is definitely a huge improvement for my current situation!! thx so much for this. One thing I did however felt was a loss of sharpness.
Shooting on an A7iii I personally use HLG3 for the most part as I felt from the beginning that it offers the best look with minimum post effort, but you will struggle to expose shots like in a house where there's a lot of windows.
Glad to hear that it worked for you too. In the end I really feel like it just comes down to the codec. And by increasing the saturation, you’re just giving yourself a better shot at being able to recover the colors.
Thanks for running the test again!
iv been using a6300 for the past 2 years and sometimes shoot with slog2 , and i always get this problem ,i thought thats my fault until i watched your video , thank you so much
Glad it helped!
One year later finally discovered this video. Thank you
My pleasure!
Interesting! Thanks for sharing.
🧡
Thank you so much for posting this Dunna! I’ve been struggling with this on the last few projects I’ve had. I’ll have to try this!
Give it a shot! I hope it helps!
Dunna Did It will do!
Such a wonderful trick as I’m completely new to Sony, this helps a ton. I had watched a few video tutorials before this, it was recommend to set the Zebra to 107+ for all. That was why it was overexposed on the face of the subject. It was my first time shooting with Sony for the clients. I wished I had watch this before the shoot. Thanks for the help, anyway
thanks dude! i'm going to give this a shot. i stopped using s-log a long time ago as well because of this same issue. well, this and i was also getting a lot of noise/grain in my footage when using s-log. I started using cine 2 and cine4 and got a way better result. I'm still shooting on the a6300 so i feel ya on that 8 bit. i need to just step it up already and upgrade cameras. i swear i feel like i've been back and forth with picture profiles and settings since i bought this camera a few years back. haha.. thanks again bro. i'll give this a shot.
Yeah! I totally hear you! I hope this helps a bit! It’s not ideal but it sure seems to be better for me.
I've never really enjoyed the workflow of color correcting and colorgrading S-Log. Also my results have not really been the as good as I wanted, but that saturation tip seems helpful. Thanks! 👍
Maybe this will be helpful! Cheers!
Love this, and I'm only 3 minutes in! I have a Sony a7iii, S-Log 2 was a feature I couldn't wait to get but I see myself using HLG3 more than anything else. People are very hit and miss with it, but it works so nicely for my workflow. Really looking forward to trying your methods!
Nice! Hopefully it helps you out! I think I’ll primarily still shoot HLG as well but it’s nice to have S-Log as an option
@@dunnadidit Absolutely! they all have their uses. I'd never shoot S-Log (or any log) in a dark environment or something that isn't lit well. Cine is a run and gun, HLG kinda just works but doesn't give you as much flexibility! I'm on a shoot for the next two days, might put this to the test and do a video on my own channel of results! I'll credit you obviously! Thanks for the tips!
@@dunnadidit dunna, mann, so after all this testing, your still gonna use HLG? lol
Sung Kim - Lol I’ll use slog now when it would be handy, super bright and dynamic scenes that I need to have high dynamic range. But yeah I’ll probably mostly shoot hlg because it’s easier to deal with.
@@dunnadidit dont worry man, when sony a7siii comes out, slog will be king again
Man oh man..! I have watched tons of videos on s-log because I’ve been having a similar problem where I was seeing that blotchiness in kinda purplish tones on my skin and none of the videos gave it like this... all those pro’s must be aware of it but none of them mentioned. Well actually I’ve stumbled upon a blog post from cody blue only I guess saying he prefers cranking up the saturation and it looks better but didn’t really explain why. And thinking my problem was totally unrelated, I thought it could have gone worse so didn’t even bother giving it a try. I was looking for cine4 profiles now but this video just opened a whole new thing for slog again. Thanks a lot man... great work. Subbed... :)
That’s great to hear! I’m glad the video helped!!
This was a great video. I've recently switched over to Sony and this issue is something that I've struggled with. Glad to see the "expose your face with zebras at 70" method, I just talked about that in my video yesterday because it helped me finally get a better overall exposure in S-LOG2. Will have to try the saturation setting as well, thanks!
Thanks so much! After finishing the whole thing I do wish I exposed it a little brighter, maybe the 70IRE over more of my face... but with that saturation trick I find it a bit more forgiving!
In my experience, I usually use slog for bright shots and use cine 4 for darker ones, I usually find that I get better results with that. If you want to make a video comparing the two profiles on different environments and listing detailed specs (pp, gamma, black level, etc), I think that would be great! I'm trying to do that myself but it's nice to have a second opinion and I'm also second guessing whether to film it.
Nice! Thanks for the suggestion Zach!
Awesome video! Soooooo helpful, I was getting so fed up with SLOG
Hopefully this helps you out a bit!
I've been having this issue for a while on my A7iii when I push the saturation or a LUT that pushes saturation. Thanks for the fix! I have been puzzling over it for a while.
Glad to help!!
Wow. This is a game changer. I gave up on slog2 after some early trials and I've been using a PP6 since then. I decided to give your idea a try and the results were very good. Yes, it seems like there should be a more elegant fix, but it seems to work for me, so I'll go with whatever gets the job done. Thank you very much.
Nice! I’m glad it was helpful!
I had the same problem and always sticked to cine4, thanks for sharing the fix
This great Dunna, If you're white that is. I have gone trough everything and as a black person having darker skin just results in madness in color so a fix for darker skin is you simply need to add a fill light to illuminate you and it should hold us pretty well.
I can totally see how that would be an issue. There are definitely different IRE levels that make sense for different skin tones. Ideally, this fix should still be helpful once you get your exposure correct but obviously you’ve got to do what you have to do to get that exposure correct in the first place like you mentioned.
Thank you thank you thank you! I understand this is not the best way for some more seasoned videographer / colourist, but after such a long time shooting with Slog (even grading with resolve) i always find my 8bit s-log is a bit frustrating. Dunna it works great now and i am happy to use my camera to do more work!
Also there is a good side effect - the footage looks great by itself if you are looking for a low-contrast de-sat look! However i think for me +32 is a bit much in my A7Riii and A7iii, so i dialed down to +15, add a little S-curve in resolve and looks great already! no need LUT!
Thanks again!
Excellent video!I use a A6500 for underwater filming and so far got the best results with S-log2 and S-gamut3 cine (and lots of cursing in post!). Underwater is a very contrast environment and lights are only useful for close shots. If you are deep you get no colors and dark shadows but a bright surface in the background..What settings would you recommend in this situation?
Hi, may I know what is your ISO (exposure) for such shot in studio? I'm trying to figure out how to use SLOG-2 for my studio which has similar lighting condition as yours. Thank you!
So clutch! Thanks Dunna 🔥
My pleasure!!
This video is really helpful because I also shooting in slog 2 and 3 with proper exposure but same issue I like this trick now I also feel confident to use it again because I started to move on Cine4 but thanks to your video now again slog 2
Great to hear!
Nice man! Thanks a lot! Starting in vid with the a7iii and this helps a lot!
Thanks so much for watching! I hope this helps!
Try the custom settings I share and let me know how it goes. I also use an a7iii. And nonetheless I completely agree with all of Dunna's philosphy.
@@sonya7tutorials252 I shot HLG3 and I'm pretty happy with it! thank you for your answer! :)
I'm struggling with this too, with Sony a7 III. So in this videos what LUT are you using if any? And what are the modifications you did in post regarding basic settings?
Wow man this confirms my suspicions about this. I had always wondered if cranking saturation would help preserve that info in camera and help out in post because the information would not be stripped out of that weak codec and you wouldn't be trying to restore something in post that's just not there resulting in artifacts.
👍🏻😁
Got my first camera (sony zv-1) and learning how to use log footage for the dynamic range. I filmed a little intro to a video in s-log 2 and the clips were basically unusable lmao. It's almost like the camera didn't capture any color. I took your advice to increase the saturation to +32 and OMG it's so much easier to color correct. I like the footage so much now that I don't even feel the need to grade it. Thank you!!
Personally, I might avoid slog with the zv1 but if you’re happy with it! That’s what really matters!
@@dunnadidit Yeah, the shadows are a bit noisy in log on the zv1.. maybe cause the iso increases to 1K? I have aperture at 1.8 for a blurry background and 1/50 shutter speed @ 24fps. I'm a newbie...
It has more to do with the sensor size than anything. With smaller sensors, you’re generally going to see more noise in equal situations, but shooting log becomes harder to grade if your signal is less clean to start.
@@dunnadidit Really helpful, thanks man!
Thats some good tips right there. I have not been wanting to mess with S-Log so I have been shooting in HLG2. Maybe one day I will be brave lol! Nice video!
Thanks Paul! I typically shoot hlg lately too, but it’s nice to have the option.
Dunna Did It for sure!
i find this to be one of the best advices for when filming in slog on 8bit sonys.
Just what I have been looking for!
Off topic but I love that you have Enders Gamer and other books in the series on your bookshelf!
All of them! Favorite series of all time. Every other book on the shelves is my wife’s but all the Ender books are mine lol
Dunna Did It Ha! that’s awesome!
I’ve been playing around with Slog 2 and I also found it frustrating working with saturation. I’m definitely going to try this setting out and compare with previous shots. Thank you!
I hope it helps!
wow so cool content. now I think most of us thinking about mobility when we travel a lot and use less wire at all
Thanks for watching.
great video! realy helpful, thanks from brasil!
The extra Canadian way you said "Maybe a bit too much spray tan ther Dunna" killed me.
Haha I thought it sounded more like a Minnesota accent lol.
@@dunnadidit I heard Minnesota, but I'm in Wisconsin, so I hear Minnesota a lot lol.
bashfoal - Lol well I’ll take that as a sign that I’m an excellent impressionist haha 😂
Thanks for the advice!!! but I need to know, what PP did you use to shoot this video (with the a7iii i'm guessing is your main)? is it also slog-2 with your tweek?
Yup! S-Log 2 with the tweak and using the ninja v.
Such a useful fix tutorial 👍🏼 soo easy to follow 😒
Thanks a lot for this vid! What's your bet on HLG3 vs. SLOG2 with all cranked up saturation?
HLG3 doesn't give you as much dynamic range but I use it pretty regularly. Its a great PP with lots of flexibility and it's much easier to grade.
I have / had a similar problem with my GH4 and V-Log. When I throw on the rec709 lut from Panasonic some of the footage is way too red and hard to fix. I found it mostly when the white balance was slightly off. Somebody made a fixed version of the rec709 lut that dials back the saturation heaps that fixes it a bit. But mostly I try to get the WB right. Sometimes if it is really bad I try and fix it without a lut at all. Now I've upgraded to the GH5 but I am yet to grade any of that luscious 10 bit footage but I can't wait to try. I still have a bucketload of 8 bit GH4 footage to grade though. Thanks Dunna this was great 😀
That’s very interesting! Thanks for sharing!
Nice Vid! I've opted the last several months to simply shoot in ITU709 in both with some slight tweaks. For my workflow and needs.... punchy color, high contrast and sharpness SOC are needed and the 6300 does a phenomenal job for that :) I messed around for a year with varying results with LOG but at the end of the day I'm not a colorist and certainly not in an 8bit space and ultimately my stock footage sales actually increased just doing it this way... :)
Nice! Thanks for sharing!!
so if i shot in ITU709 I don’t need to convert to rec709 in Post?
@@thomasshakelton No need, it’s baked in and captured at REC709 value/curve. Using any kind of LOG on anything below 10-bit is tricky and overall limited. I’ve moved on to the FX3 and shooting in 10-bit and the difference on this specific topic is truly remarkable. For 8-bit capture I highly recommend testing and finding suitable in camera looks and baking them in. Or just using 709 and use the physic space to achieve a look.
With my a6300 I will shoot in SLOG2 and I will grade but I also do so in very good lighting and knowing I want to achieve a very “regular” look.
@@AdemVessell thanks appreciate it, ITU709 makes the skin way to magenta for me S-Gamut plus the rec709 correction is posts does the job pretty good. all the best
@@thomasshakelton may I know how to convert to rec709 in post?
Definitely going to give this a rip! Going on a trip this week, and I'm only bring the a6300, so this will be cool to try!
Nice!! Now I have to do a pile of testing to see if it’s any better when I record into the ninja v lol
i've been struggling with this withmy a6500 too this was good to see. Does this issue persist with A7SIII?
After struggling with SLOG2 a couple years I came to the conclusion that the best looks for Sony A7 series cameras are the baked in looks, like cine 2 and cine 4. The logs are just too robust for the 8 bit codec. Then, I bought a RED, and wow. Yes, I know that’s like comparing a BB gun to a Howitzer, but RED raw files are nuts. No longer do I have to struggle with grading because they pretty much take whatever you throw at them and then some.
My only experience with RAW/RAW-ish is my Canon EOS M with Magic Lantern (12-BIT setting) and Blackmagic Pocket Cinema Original (ProsRes). No denying, both these cameras are simply "filmic" right off the senor but the low-light is hard to work with on both. I'm looking into something similar but with better low-light. I'm sure i can get close enough with my a6300 but i would like to dodge that process in editing. RED seems to be my best bet. I'm not a fan of Blackmagic's MFT and now Super35 sensor product because they no longer have that Filmic look right off the sensor. They stopped using Fairchild sensors but i have a feeling its because ARRI and RED made a big deal about it.
Hey Dunna, thanks for yout tips. I have a question. Im using the SLog2 on my Sony A7C, should I use the same SLog 2 settings on my Sony ZV1 which is my B Camera?
Do you film the talks and the studio with the a7iii? and which lens? The quality in your studio its just soooo amazing man and crispy sharp! Any secret ingredients?
For this video it was the a7iii with the Tamron 17-28 I believe. Honestly, setting up proper lighting makes a big difference
What if you are trying to shoot something in a darker setting? Less natural light, but some artificial light. In a darker room for example (not DARK, but "darker") where you aren't worried about over exposing, but you want to make sure you are shooting with the right settings to grade correctly in post.
Hi dunna, quick question. how did you turn on the AF ON & on what mode do you use it? thank you
Hi, Recently I had the same issue. Not just having that weird ugly spots on my footage but the dark red going towards magenta as well. I was shooting a video for a client and this scared me a lot as I was shooting fresh food and the color wasn't looking great. I pulled it off by adjusting the color curves. It took forever and in some places was still looking a bit weird. Anyway, I did some tests with S-LOG. Please try it as well and let me know if it works for you at all . I used the S-Log 2 with Color Mode S-Gmut3 and S-Gmut3-cine when I had the issues. I changed the S-log 2 Color mode to S-Gmut and now everything looks great again. I did try this in natural light and artificial and it worked. As well as S-Gmut3 and S-Gmut3 Cine seems to work more with the Slog3 rather than Slog 2. Let me know your thoughts
Thank you so much! I'm working on the color grading of a project that was filmed in 8 bits and it has this splotchy color problem, is there a way i can save this videos in postproduction?
Try your best to be gentle with it in the grade. The more you push it, the more noticeable that gets. Noise reduction can help too.
So Dunna I had the same difficulty when I first got my sony a6500 and shooting slog2. I totally ditched it and used cine instead. But a few weeks ago I did a huge research into it and finally managed to figure it out. Actually slog2 has two distinct advantages. Increased dynamic rage and BIGGER GAMUT (AKA S-GAMUT) it is not just desaturated, It is actually wider than Rec709. Long story short you have to first use a correction LUT to map it back to Rec709 using sony's official correction lut (instead of bumping the saturation slider) this way the gamut part is corrected and then use s-curve to correct the dynamic range and contrast. Trust me it works like a charm 😉
Actually, I tried this in this video. I used Sony’s supplied S-Log2 to Rec709 lut and had the exact same problem as when I cranked the saturation. I definitely understand what’s going on when I’m using SLOG2. Like I put on a title in the video and in a pinned comment here, I just simplified things for the sake of the video. That said, I have tried using the proper conversion luts (of course I tried that first) but still had the same issues. I also tried a variety of different exposure methods but regardless, had the same issues, overexposing helped a bit but then came into different issues with the mid tones being flat and unrecoverable and anything that was a little darker in the scene had the splotchy issue. So unfortunately the Sony correction lut isn’t the answer for me here. Thanks for the input though!
@@dunnadidit I have to apologize for jumping to conclusion without first watching the video completely. Thank you so much for making this point clear to me. And thanks for putting the time amd effort into making these videos. I totally appreciate it. Keep up the good work 👌
No stress! I appreciate that you were trying to help! It’s an awesome an helpful community here! Thanks for the kind words!
Dunna Did It Search for joo works tutorial, he made a perfect lut for S Log and it’s free too
Hey man do you have a video explaining S-Log and or Sony Picture Profiles? I’ve been just using it in my camera and playing with it but I wanna know everything about it
I don't have one yet, but I highly recommend doing a search for Gerald Undone's videos on picture profiles in the mean time!
For the underexposed stuff you can change the metering mood to spot, if is a subject in this case that you want to expose properly without care about the rest as you said ! Big up bro !
THANKS FOR SHARING THIS INFORMATION.... LET ME TRY THIS ...
My Pleasure!
I m a beginner...Your tutorial was helped me a lot...Thanks
Awesome Dunna! This will help me a lot! Just picked up the a6500! Do you have any tips on the quality loss with 1080p 120fps?
Lol, my fix for the quality loss was to shoot 60fps instead haha. I avoided 120p like the plague for so long.
Dunna Did It thxs man did you notice a big difference in quality?
The 60p definitely looked cleaner for sure. The 120p always got a bit soft.
i'm gonna try this 100%..another issue i have with S-log2 is that sometimes the image is so low-saturated that even cranking up the saturation to the extreme it barely shows up any color, and if it does there's the whole pixel/blotchy mess that you show in this video..thanks!
How are you correcting it afterwards? Sounds like maybe you need to use a conversion lut as well as some extra saturation.
@@dunnadidit when that happens i try to find a good middle ground in some way, sometimes i even used a couple of adjustment layers with lumetri with changes to specific colors..i've tried an Slog to rec709 lut once but the result was so awful that i gave up trying after a month.
A few days ago i went to the beach to get some material to practice color grading, i've tried under exposing a little bit and that worked on some clips but not enough..i still have a pretty much black and white image despite the almost sunset colors
That’s really interesting. I can’t say that I share that experience.
Thanks dude! been having the same issue!
Hope this helps!!
what's the 'dunna fix' you're referring to? is it just a lut you made to try and fix the splotches?
1. Not sure WHY I hadn't subscribed yet... took care of that lol.
2. You CAN still edit Lumetri Colors after you apply a LUT, but it's more "where" you use it. For LUTS, if you apply a LUT into the "Creative" tab rather than the "Basic Correction" tab, you will still retain the footage data to freely edit your Lumetri data, even w/ the LUT active, and w/o "pancaking" data on top of the LUT and footage falling apart. Of course this isn't DIRECTLY related to your solution for blotchiness which I'm trying out now, but I just saw you using LUTS in Basic Correction, and I know how annoying it is to have to turn the FX on and off for reference. Took me a while to learn this, but hope it's of use to you Dunna. Thanks again for your content bro!
1. Thanks for subscribing!
2. Totally! I typically use corrective luts like the ones I used in the video in the basic correction tab. Then in the creative tab I will use any creative luts I might want. But from time to time I’ll use a corrective lut in the creative tab so that I can use the basic tab to adjust exposure going “into” the lut. Or sometimes I’ll just add another lumetri instance prior to the one with the lut on it.
Dunna Did It solid man, again great content! Your Edelkrone vs Rhino video got me on board lol, saved me a few grand!
this worked wonders..thanks for this
Great to hear!!
S-LOG falls apart because you sacrifice color for dynamic range. As you stated, it's an issue with 8-bit cameras (the kind most UA-camrs use). I'm interested to experiment with your workaround, increasing the in-camera saturation.
Very Helpful thank you!
My pleasure!!
Hey Dunna Quick question, do you know if there is a way to figure out what picture profile are used after I’ve shot a bunch of stuff using Slog2, Slog3, HLG etc. but did not label them?
When you go to grab the video files, there is a sidecar file beside each video file. I'm pretty sure the info will be in there somewhere. It might be kind of hidden but I'm pretty sure it's in there.
Hey, thank you! Where can I get the official Sony LUT for the A73? Best
Ok. I gotta try this. I'm SO colorblind that the yellow/ red skin blotches don't even register for me, so fixing them has been IMPOSSIBLE. I can tell something isnt right, but can't get there. Cine 4 has been good for me, and looks similar to the Dunna Fix so I'll have to try your method and see how my eyes fare!
Nice! Let me know if it helps! Cine4 is solid too!
You don’t get usable dynamic range if you going to expose like that because it’s way underexposed you need to expose your shadows until they above 40 ire it’s or overexpose for 2 stops if you don’t know how to deal with histogram or waveforms
I hear you... I've tried "overexposing" as well, but I find that my midtones never fully recover from that. They always look weird and washed out. And then on top of that, the highlights get super blown out and unrecoverable. Again, I have a feeling that this is because of the codec, bit rates etc from these cameras and might not be the case if we had 10 bit 4:2:2. But like I said in the video, I would prefer to blow out my highlights a little and get my skin looking better and this method (skin to approx 70IRE) seems to have worked best for me in my testing (believe me, I tried a TON of different exposure options). I appreciate the input!
Dunna Did It I have a video called get the most out of Sony A7III I shot it entirely in SLOG2 and every clip I tried expose +2 stops. There was a clip I shot 51200 ISO but because I exposed right I don’t have weird artifacts, and a pro tip not to use s-gamut at all if you want to prevent codec from falling apart, try to use rec.709 matrix with s-log2/3 gammas you will get even better results
This trick just saved me from that blotch skin.. thanks a lot. But right now I'm struggling with another issue... noise! No matter how much I overexpose, the shadows always have that terrible noise... but here in your shots, but in tests and the introduction part, I see a lot less noise. Did you use denoise or is it like this directly from the camera? If so, what is your secret? :)
I use Resolve17 denoise. 3frames, select 'better', then crank up as least as possible. I think denoise is not included in the free version.
Had that problem for ages and just used Neat Video v5 yesterday to build a ridiculous amount of noise profiles for my A7III to remove the macro blocking present when I shoot in Slog2. The results look really nice (especially when you convert from Slog2 to Slog3 in post and then grade), but it's slooooow. I'm looking forward to trying your suggestion Dunna. If I can get this to work without NR, I'm a happy bunny :-)
Hopefully it takes some of that hassle out for you! Obviously you’re losing some of the potential advantages of having extra range in your colors too but I’ve never had any problems with it clipping colors still.
Dunna Did It It does indeed, thanks a lot. I tried it today and it definitely holds up a lot better, but I still found a couple of blocky nasties on my fiancée’s face. Slog2 on the A7 III is really prissy. I really don’t want to jump onto that bandwagon, but part of me hopes the A7S III will solve all of those problems (I mean dear God if it doesn’t). Until then it’s Neat Video and Saturation at 32+ 😉👍
Glad it helped a bit. Maybe don’t tell your fiancé that they have “blocky nasties” on their face or they might get the wrong idea 😂
Yeah hopefully the a7siii does better. Even just the bigger pixels should help. I notice a difference between my a6600 and my a7iii so fingers crossed🤞🏻
Dunna Did It 😄 Luckily she doesn’t hang around UA-cam anymore. Fingers crossed on whatever Sony’s gonna deliver end of July. Don’t wanna have to sell all my gear again 😶
Great tip, Dunna, I'd given up on SLOG been shooting HLG2 but will give this a go. Quick question, though. I noticed the eye autofocus seems to be following you even when you're not holding down the focus button, how is this achieved? Only seems to happen when I press record on my a6600.
Hmm, if you're in movie mode on the a6600, it will automatically go into AF-C and the eye autofocus should be working. Not sure why it wouldn't be, unless you're in a photo mode and recording from there... maybe that would do it?
@@dunnadidit Ah yes, I guess that's it only works in movie mode. Thanks a mill.
you is nice human Dun.. thankyou 👍🏻
hey Dunna !!
one question.... I saw other videos about this (Becki and Chris) and they did the same thing with their sony a6600 camera... but does this work with the Sony a7iii?
Sure does!!
Can you post a link to the original footage in video that you have the problem with and the LUT you are using that useing
the problem?
@Dunna Did It thank You for sharing these informations. Im a beginner and sometimes it happens on my videos what i can see on yours as well that your background is in blocks, circles. Your t-shirt as well. can You tell me why? Thank You in advance.
Great video!
Have you tried HLG? I’d be interested in seeing your results with that profile (or a tweaked version of it) 👍
Hey! Actually I’ve been shooting HLG for a little while now and I really like it. It’s nice and easy to deal with which is nice. Not quite as much DR as S-Log but still helpful. I’d say the last... 6 months of videos are in hlg
I also had some issues with s log. I didn't hate it but I wasn't that impressed. The first project I took a chance on with hlg was a paying gig which was risky but I was more than happy with the results. I've been shooting hlg ever since.
Great video!!! My a6300 wont go below ISO 800 in slog2...What gives?? any suggestions would be much appreciated!
Thanks, I'm finding lowering the "Col Boosting" in Resolve gets rid of the blotchiness.
Great video!
Have you given HLG2/HLG3 a try? Seems to have improved dynamic range and lower minimum ISO. Would love to know your thoughts! :)
Have a blessed day!
Hey! Thank you. Yeah I’ve actually been shooting HLG for quite some time now. It’s good, and it’s easy to grade, not quite the same dynamic range capabilities as S-Log but definitely better than no PP.
@@dunnadidit so if i shot in HLG I don’t need to convert to rec709 in Post?
I simply use some well designed LUT's that I bought and then I just fine tune it from there. Never had any problems with blotchy skin or stuff like that since I don't really wanna deal with color grading it from scratch anyway :D
Doesn’t seem to matter whether I use a lut or go from scratch though. As I demonstrated in the video, that problem was baked into the footage once it was recorded so no matter how you grade it, it’s there. The nice thing about doing this is that I can still use luts, they just look better now.
@@dunnadidit Hmmm weird. Maybe the footage was just too underexposed I guess..? Your example did look fairly noisy in the shadows so maybe it was just the noise pattern "overpowering" the low bitrate so putting any kind of color grade was already too much to handle. I could be talking completely out of my ass here. Did you get the same problems when filming outside with enough light available? I usually overexpose the skin tones by about 1.5 to 2 stops or with skin tones at 60 IRE. And I don't care if a window is blown out I always prioritise the subject (skin). You can only expect so much dynamic range out of these types of cameras.

I did try this as well pushing the exposure higher and the problems persisted. I've done some other shooting outside and followed the typical "overexpose for 2 stops" rule but I always found that when I did that, my mid tones were always weirdly washed out and I could never get them looking natural again. Of course there is always more experimentation to do, I definitely don't want to make it seem like this is the only way... just the way that worked best for me so far. And I totally agree about blowing out a window to get the skin right. In fact, the way that I did it sounds like it lines up with what you're saying. Most of my skin would have been around 60IRE since that side highlight was around 70. But, again, like you said, you can really only expect so much from these cameras haha. It was a super dynamic scene for sure.
hi, I'm getting noise on black objects in slog2 even on 2stop exposure, my iso was 1250, what should i do to fix this?
Helpful thanks 😊
Thanks for watching!
Are you familiar with the Leeming LUTs for Sony? Those of us who are have been doing this for a while. Although, even those have their own pitfalls and can yield unexpected results the first couple of times using them.
Yeah, I use the leeming luts most of the time. Actually I found out after this that he uses this trick in his s-log too! He gets you to crank up the saturation in your picture profile. I find his exposure rules a bit difficult to follow all the time but getting a monitor with luts has helped a lot because I can just shoot with his luts already applied.
HAHA WOW! I am coming from Panasonic where I could navigate the menu with my eyes closed... I can barely navigate Sony menus with both hands while a tutorial for Sony menus plays on one side and the owners manual is open on the other side! Dunna is navigating these menus like a NINJA! haha... good work... I can't wait for the a7Siii to be here to give us proper 10 bit and the latitude to really push log to its limits like I can with my S1H!
Haha 😂 I’ve never really had that much trouble with the Sony menus. I always felt like people made a bigger deal out of it than it was. But I do have a theory! With certain things in life, it makes it easier to then learn another similar thing. Like when you learn one instrument, it’s easier to then learn another one. But I think menus is the opposite... once you learn one, it becomes HARDER to learn another one because you’re fighting all your instincts and muscle memory. But also I’m a huge nerd who thinks about these things lol 😂
