Exposing using EL ZONE in post & creating MONITOR LUTs
UPDATE
It turns out EL Zone is patented, so I've had to remove the files I originally had available for download, sorry.
EL Zone is a simple but powerful idea. Let’s display digital image values as ‘stops’ of linear light, just as we do on-set. So far, this system is limited to SmallHD monitors and a select few cameras, but in this video I go through the EL Zone DCTL that I made to use this in colour grading, and how to export a LUT to use this system (in a limited way) on any monitor or camera that supports LUTs.
00:00 - Introduction
00:15 - The problem with false colour
01:22 - What is EL Zone?
03:51 - How the DCTL works
07:38 - How to use the DCTL in Resolve
10:34 - Using the DCTL in a grading workflow
13:43 - Exporting a LUT for monitoring
15:19 - Drawbacks of LUT workaround
16:37 - Outro

ELIMINATE ROLLING SHUTTER on BLACKMAGIC cameras?!
Переглядів 34 тис.Рік тому
Apparently we've been able to do this for ages, but I didn't know about it! I assume I can't be the only one because I keep seeing people complaining about jello on blackmagic cameras, so I made this video as a public service announcement. 00:00 - intro 00:28 - Rolling Shutter 02:38 - Gyro Stabilization 04:27 - Correcting the footage 05:59 - Results 06:45 - Takeaway 08:24 - Limitations 09:24 - ...
So i copied the code exactly, triple checked it and brought it into Resolve and nothing happened to the image
I know you’ve taken it down but since you aren’t selling it can you send it to me privately? I’m out of options on getting this feature
If anyone downloaded this before please message me!
awesome video! I want to use this to replicate other cinematographers and practice. I downloaded some stills from IMDB but when. i went. to use this dltc it was off... I believe I coded everything right, I tried transforming the stills to linear as well but the output color space could not be turned to linear. I am missing that grey card thing you have in one of your nodes. could that be affecting something? how would you go about using this with misc movie stills that you want to replicate?
Hello, please tell me where did you download DCTL linear expansion? I searched the Internet everywhere and didn't find it
Besides open gate, the Cinema 6k and Pyxis has better rolling shutter than the Sony FX9 and the same 22ms as the Sony Burano that cost $25,000. People just complain too much and it’s really ruining the independent film maker’s world. The FX3 has less pixels and only shoot 4k. People need to stop complaining or just don’t buy the camera.
Any why to get a .cube file to test it with my monitor?
great. Thank you.
This is a great video !!! was able to create the DCTL , exactly. recoded what was shown in the video. Things seems to work but only problem is - the colors are not coming correctly as per the EL zone. Middle gray shows as +1 stop .. and only 4-5 band shows up when I use it on the exposure gray card DTCL I checked code multiple times and luminance range for each if else and RGB even thing looks fine in the code, but I nearly see the right EL zone for any of the exposure gray card. Any suggestion help is much appreciated
Where I can get this Grey Card FX? 13:15
I tried copying all the text from the code to recreate this DCTL for my use, and generate my LUT, but when I put the DCTL in the Davinci LUT folder and apply it to the video, nothing happens. I copied your code exactly as it is. Any tips?
i have the same problem, have you figured it out?
Thank you for showing this I had no idea and I’ve been shooting black magic for 5+yrs
I managed to create the DCTL and it seems to work flawlessly on my s5iix. I set a function button to "LUT select" so I can easily switch between the ELZ LUT and the Rec709. viewing LUT. I set another function button to turn on/off LUTs so I can quickly see the VLOG display (not ideal but quick) to check the framing which works well for simple shots. For run and gun stuff this will work well for me without external monitor and for more serious work I always use an external monitor anyway I found one caveat: colors are not very accurately displayed in the viewfinder - which is a bit of a bummer - because I use the viewfinder a lot. I will be searching for an exposure DCTL to emulate how you adjust exposure in post. Overall this is a great solution for exposing - certainly much better than waveforms or false color. THANKS A LOT FOR SHARING! And please keep posting, your content is highly appreciated :)
would you mind passing it. i copied the code but it dosen do anything for me
You could change game to linear in your exposure node and work the gain wheel only, pretty similar
Good day, can you send me the out ?
bro what the fuck 😲😲😲😲
Just so you guys know Monitor+ has El Zone support kind of "hidden", you need to press and hold the False color icon and it will show up!
But this is only in a Pro version AFAIR.
@@JoATTech yup!
@@JonatanCastro I wonder if they are licensed, I have Pro version, but wouldn't like if some day EL-Zones disappear :D.
@@JoATTech I don't think so; they don't mention it on their website. But it's also very stupid that this is actually patented, only in the US, I guess.
@@JonatanCastro Yeah, it's like patenting breathing ...
Anyone has that link to the DCTL?
You're still losing material. The best thing to do is getting a camera with good rolling-shutter performance (or a global shutter). Sadly, a lot of the recently-released cameras' chip-readout times suck. Anyway, this video lacks any substantial demonstration of legitimate jello effect, which occurs during UP-&-DOWN movement.
Thanks
I copied the code, and it doesn't seem to be working correctly on my Ursa Mini Pro G2. It shows the wrong values. Do I need to alter the DCT for my camera dynamic range? How can I do this? 14-15 stops dynamic range. Need a monitoring lut. This is amazing stuff man!
This is pretty cool! It's easy enough to find the code and make the DCTL. The unfortunate thing is dealing with Linear gamma and having the wrong previews in the clip view.
mega
Atomos also has it as paid upgrade to their monitors.
I'm selling a Blackmagic Production Camera 4K that has GLOBAL shutter if you're interested.
does anybody still have the file or the link and could DM
Im still looking
I’ve nearly made my own but I’m having trouble confirming it is bulletproof. I can’t find an exposure chart with 1/2 values above and below middle grey. If anyone can assist in finding one like his, I may be able to send you a DCTL
Is there any place we can find this lut? Asking for a friend
wow nice! . I just bought a S5iiX :( @ChannelPanasonic please add this gyro thing on the next firmware !
Is there any chance of someone sharing this DCTL privately??? 🙏🏻🙏🏻🙏🏻 It's a shame a tool THIS GOOD is not allowed to be shared… 🥲 klqwdhjkqlwdh
Hi mate, thanks for the video and easy enough to code. Have you found underexposure to be way more sensitive than overexposure? Just seems to be far more limited range on the darker areas
Then when filming scenes you will need to stabilize in post, perhaps best to shoot a tad wider b/c you will need to crop.
I actually didn’t know this either. I know the gyro stabilization but never knew it would actually fix the jello effect. Very impressive and thank you.
It baffles me why this video is 8min long if its only one button?
WOW did not know this, thank you!!
Do you sell the DCTL for the EL Zone system? I’m clueless on how to make one. I want to study other films using the DCTL.
hy, is there any way to get the lut now?
More content please! Amazing videos
T H A N K Y O U ! ! !
this is genuis!!
AI helped me to generate code for this. It works nice inside davinci when log converted to linear before the DCTL node. I converted it to .vlt LUT and put into my lumix S5iix but everything is so dark on camera monitor.
I didn't known about this features. Thank You for sharing Yours knowledge
Whoa, I gotta try this!
thanks crack!!
This is fantastic, well done! Too late for the download but easy enough to rewrite my own code. Works great in Resolve, however, when I make a LUT the DCTL node is ignored, so I get a LUT with just the CST to Linear. Any ideas why?
But, for me it is innacurate
thanks man
Fantastic thank you!!! I can't believe this is the first time im hearing about it.
H is pronounced AYDGE, not "haydge".
When you mentioned focal length of lens and the fact you have to specify that for Davinci Resolve, I immediately thought I cannot use this tool if I use Metabones speed booster with vintage Nikon F or M42 lens. I assume there is no way to give sufficient amount of information for Davinci Resolve in order to do its thing, so its better just assume this method is out of my reach as long as I use the speed booster and vintage lenses. Am I right?
That's why I don't care for nerds who talk about gear, but have nothing to show for. UA-cam is a sea of pixel peepers who have either a portfolio that feels soulless or worse don't even have anything and who talk about specs as if they're pc gamers comparing technicalities of PC components. But the fix isn't a great fix, the image is getting cropped in and you're losing some parts of the image.
Ok but anyway its better save money and go to sony, we need adapt if we want work with tecnology
Is there any way I can set the focal length after the footage has been shot?
This crops the sensor - quite a lot, actually. It doesn't just fix it with no downside. You might as well just shoot cropped and have a faster readout. Also, as you mentioned, it only works for jello caused by the camera moving and the rest of what you're shooting staying still; if what you're shooting moves it will still be distorted. It's all a bit dumb, TBH.
