Rendered output color not matching

I’ve been testing capturing through HDMI, and everything seems to be working pretty well except the color rendering.  The color as displayed in screenflow seems to be fine, but when it’s rendered to file or to Vimeo, colors are off pretty dramatically. this only happens when I capture the HDMI feed into screenflow, if I capture it with Quicktime and then place that into screenflow I haven’t had any problems.  

This doesn’t affect the screen capture colors at all. 

I would be great to use ScreenFlow to capture 4k video from a decent camera (have tested it with several Sony cameras), but need to figure out why the color mismatch and if there is a way to prevent it.  On the video am working on one clip capture at the end rendered’s fine, but all the other clips seems to render like the attached file. (left is screenflow, right is rendered file opened in QuickTime)

Catalina 10.15.2, ScreenFlow 9.0.1. Using a BenQ 271 and a NEC 302W display (both high gamut displays).

Thanks for any thoughts.

    I’m using an Elgato Camlink 4k, he is using an Elgato Camlink.

     Perhaps something about the Camlink and what ScreenFlow sees from it. 

    Wayne Fox said:
    screenFlow will appear oversaturated, and will only appear somewhat normal when exported (via any codec)

     That could mean it's related to how ScreenFlow uses GPU for display vs export (where it may not have the same impact).

    Since it may be specific to Elgato and recent MBP GPUs and OS...

    Both should fill out the form. Include ScreenFlow version, macOS version (the specific number). specific MBP model, input device (Camlink device). 

    We're going to need a very exact step by step workflow test including both Quicktime and ScreenFlow so we can duplicate it. 

    ScreenFlow Support Form

    Since I only tested with Facetime, while I see a display difference between Quicktime and inside ScreenFlow, the ScreenFlow export closely matches the Quicktime export on my end. So the technicians need to do precisely match your steps.

  • Any updates on this? I've also proven ScreenFlow's massive color inaccuracies in another thread: https://telestreamforum.forumbee.com/t/x19cyt/i-love-screenflow-but-three-issues-are-preventing-me-from-leaving-premiere-behind

    ...boy, does ScreenFlow love to exaggerate red.

  • Thanks as always  CraigS , just submitted my ticket using the support form (case number 00734756). For your reference, this is what I wrote:

    Hi guys,

    Your QA staff CraigS has asked me to fill out this support form to help you examine Internal Reference FLOW-10330.

    Steps to reproduce.

    1. Open Source file in QuickTime: https://www.dropbox.com/s/0q6p74v13dt9o6h/DSLR%20Quicktime%20Test%20%28original%20h264%29.mov?dl=0

    2. Confirm that there is barely any red visible in the facial area.

    3. Import Source file to ScreenFlow 9.0.3 and export as ProRes file. Notice a staggering difference in color.

    4. For comparison, render the Source file into ProRes by right clicking from Finder. Open the ScreenFlow ProRes 422 export and the Finder conversion and compare. Watch the background and the cheeks in particular to notice the differences.

    5. Confirm that the Finder conversion stays very close to the original h264. Confirm that in the ScreenFlow ProRes 422 export, there's a drastic shift towards the red, with an immense loss in saturation in the ScreenFlow export. ScreenFlow also encodes lower exposure and shifts magenta.


    I hope that these instructions help you to track down & hopefully solve this issue!

  • When is this going to be resolved? CraigS do you even have a workaround?

     

    this is an issue on every export and multiple users are reporting the issue. 
     

    30% gain in red totally bricks the software. It’s worthless unless users can export their files to look the way they were created.

     

    thanks

  • Excuse me for the support of Screenflow, I had already contacted you to solve this problem and as I saw in the responses to the open ticket, here I also saw a reluctance to admit a problem that ALL users are having. There is an absurd change in the colors captured directly in the screenflow and now, from what I see, also in files imported from other equipment. I believe it is a very serious problem, because currently I cannot count on the screenflow, neither to record on it, nor to edit, because I import videos from other equipment and they appear already changed. "ah, but you should export to ProRes and see how it looks after" I shouldn't have to export to see how my project's color will look, I need to see the color on the timeline.

    Waiting for a solution of the problem.

     For testing purposes, we need to examine input, vs display vs export. Each point to different issues in color management.

  • I was excited to see the screenflow update because I thought this would be fixed. Alas, still exporting skin tones bright red. When will this be fixed?

  • CraigS  what have the investigations revealed? I’ve got several projects that I’d love to use screenflow for, but will have to use Adobe/Apple if the color issues aren’t fixed. Thanks!

    • John Beede Since I reported the problem here, I stopped using Screenflow and I'm using Camtasia, unfortunately, after 6 years of using Screenflow, I learned how to use other software because Screenflow simply became a bad thing.

    • Elias Coutinho de Oliveira yeah that’s unfortunately what I’ve had to figure out, too. The interface is great, but if the files don’t export correctly, the software is completely bricked

    Sorry, this is taking some time as it's a fairly difficult issue and is requiring some work on ScreenFlow color handling. Yet it does seem to impact some users more than others.

    Like
    • CraigS ,I don't understand how this impacts only a few users. For me, in almost any medium I use there are terrible color changes.
      On my iphone 8, there are changes that I can't get around by adjusting the colors in the software. But anyway, let's hope that the maintenance of this does not come only after a paid update, as this one for me has already been lost.

    • CraigS seems like it's affecting everyone who uses the software. 👆

       There are some people seeing this but many aren't seeing a difference as significant as posted by those on this thread. This may be one reason why there's some challenge in this. Apparently, there's some variation in color handling. That's why it's not as simple as shifting/offsetting everything. It has to work with all the variables.

      We're working on it. I can't give dates on this though.
