    Hope this quick video is helpful to you. While these ideas are nothing new, I have found it interesting the number of people who have commented or asked about their Fuji F-Log2 footage looking more noisy than desired. I also haven't seen a lot of helpful info from other Fuji users about how to both maximize dynamic range but also eliminate noise from the get go in camera as NR in post is not always the move. This video aims to be just one piece in the equation of how you might choose to expose whatever you are filming. Thanks for being here!

    I've been overexposing my fuji footage by +1/3 when shooting 400% Eterna (gives the same result as flog1). So, it is good to know that the same principle applies here with flog2 even if we are overexposing a tad bit more. A lot of people just say to denoise but that slows down the timeline so much when I just want to chop and deliver the project.

    Great content as always. I've been shooting with my X-H2S for a while and it's always nice seeing how other people handle F-FLOG2. I typically overexpose by at least a full stop - so long as I'm not clipping any highlights - and then bring the exposure back down just like you showed in this example. Regarding the issue you ran into with underexposing when using an external monitor, I've actually made my own LUTs that intentionally bring the total exposure down by a full stop. That way, I'm already accounting for that one stop of pull--down that I know I'm going to do in post and seeing a more accurate version of the image on my external monitor. As always, cross reference that with the zebras on the camera monitor to be safe. I hope that helps!

    • @matango1979

      One trick with the XT3 is to research which ISO values are the least noisy. Most people think the higher you go the more noise. That's not true. In the case of the XT3 the cleanest values are 640 and 2000. You can go a tiny bit higher, but never go a little lower. 2000 looks significantly better than 1600. Zoom into a darker area and compare.

    I seriously recommend against overexposing Log footage.
    If you know how log manages to cram the linear light levels from the scenes which create a massive amount of data into log using lower bitdepth than what is required from linear, you'll know that isn't done without sacrifice. With log this is achieved by compressing the tonal range of the highlights and shadows while the midtone is wider with it's tonal range. Meaning if you don't place the scene where it's supposed to be in the log curve but instead overexpose, you'll end up compressing the light levels massively leading to less tonal range in the image. This is much more noticeable with HDR.
    Log and RAW are supposed to be noisy if the noise reduction is off or toned down. Avoiding noise entirely causes issues down the line. So if you can keep noise within manageable levels, your footage should do well.
    I highly recommend studying the log curve you work with

      Good note. I don't think I can as Resolve still doesn't have native support for F-Log 2 just original F-Log. Let me know if I am wrong on that but didn't see a way to select that? Selecting F-Log 1 does help it behave more linearly but still not exactly.

    By having your shutter speed over the fps, are you not getting a jumpy feeling in your video?

    • @blasepivovar
      @blasepivovar  9 місяців тому +7

      Yo! So yeah anything more than twice your fps will have less motion blur. In this scenario, sitting and talking to camera the difference is negligible and was the quickest way to demonstrate. Could have done the same thing with adjusting the aperture or using an ND but results would be the same. There are certain projects where I don't think cranking the shutter is bad. Others were I like to keep it at 180* - hope that helps :)

    H265 will compress dark areas more than bright ones, so just wonder if the result would be the same with ProRes 422 HQ? If ProRes behaves differently (as it should be the case), it'd still be recommended to expose skin tones for the right IRE value.

    Amazing! Have you worked with s-log 3 much? How do you find the noise and dynamic range compares? Also slightly confused as I've read and seen in tests that the xh2s actually has better dynamic range over the fx3 in s-log 3 which confuses me as the clipping point for f-log 2 is 85 while s-log 3 is 94 so should slog not be better? Anyways such a helpful video, thinking about picking an xh2s up pretty soon!

When it comes to dynamic range I'm not the best with all the technical info so not sure what exactly would contribute to the XH2S having more latitude. Both look great when exposed well and graded in my opinion :)

      Yo! Maybe not what you would expect, but for anything that requires a high ISO / low light I actually prefer to switch to classic chrome. I feel comfortable pushing up to ISO 6400 with CC if its really needed. When filming in F-Log 2 I am almost always keeping it at ISO 1250. In CC, There is a dual gain at ISO 500 that cleans up quite a bit. But just google XH2S Sensor Measurement charts and take a look at the data on those. Hope that helps!
