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.

  • 3.5 hours of mind-numbing exports later, I discovered some solutions that work for me as well as some triggers for the red output... I'm posting in the hopes that I can help someone else not have to waste days of their time and miss deadlines like I have because of this flaw.

    The solution is in video filters, NOT the saturation, brightness, contrast sliders. I added the following and add them IN THIS ORDER:

    1. Hue adjust 2 degrees. 
    2. Vibrance +.2 (not -.2 which doesn't read as being any different)
    3. White point adjust to: #F3FFFE

    The white point adjust is the MOST important factor! Even just adding a white point filter will improve your video colors 90%. BUT if you add it before the hue and vibrance, it will negate the effect of the white point adjustment and spit out a red file. However, if you add it last, it will make the output look similar to the source file. 

    If you add those video filters, you can export in automatic (h264) AND prores422 with a file output that looks very similar to the source file. perhaps you'll have to make a few changes based on your hardware, but you can see by the image that it made a massive difference. 

    Next, for craig, i discovered some things. Please pass this along to developers. It may help... and I don't want to keep adding these filters and still want to work with screenflow because other than this, it's an awesome software: 

    1. When an external monitor is connected, the output is a different shade of red. Awful either way, but it does affect the output. 

    2. When the screenflow window is moved across monitors, the bright red color takes over the viewer window until the image or storyboard thumbnail is clicked. Perhaps this is a clue. Further, moving back and forth will continue to compound the red. 

    3. Finally, opening files in VLC makes them look more red than when opening in quicktime. again, perhaps a clue if you use programming that's similar to VLC.

      It's interesting that when a screen recording is made using QuickTime, when it is played in VLC it does not exhibit any red bias. Here's the workaround I have been using if I want create a fairly high quality file without the red bias. I export using Web High, select Customize, and process using Hardware Accelerated Apple H264. I also choose a fairly high bit rate; instead of the default 3000 Kbps, I enter 30,00 Kbps. I export the audio separately in lossless wav, and combine it, usually after normalizing, maintaining it in lossless wav, with the exported video file, in an MOV container.

      Trevor Henderson  That sounds like it would add a lot to the workflow. The main reason I use ScreenFlow is because - in theory - I can record my talking head - and my screen, quickly edit how they work together - and export. (and save the file for future edits)

     Please be patient while we work on the issue. We're doing our investigation so we are well aware of the issues and the complexity.

      CraigS We have no choice but to be patient. However, it would be much easier to feel confident in the company - if there was ANY proof that there is anything happening. So far - it's just your words. And you're a cat. 😉

       Work is being done. Short of a decision on public betas you'll have to trust the process.

     Perhaps an example of the complexity as that involves the GPU. Keep in mind monitor calibration though. Different monitors may not match.

     Different players decode differently. Again why the issue is complex and we need to test with calibrated equipment. We would use our Telestream Switch for example, as it is designed for broadcast-quality control using our own decoders.

    • CraigS Yesterday I made a screen recording involving a lower resolution video, with my previously mentioned workaround using the custom settings and Hardware Accelerated Apple H264 for export, but it still had significant increased redness, so I had to use a QuickTime screen recording instead.

      Trevor Henderson In my experience... even if I were to record the video separately from ScreenFlow, it will still change the color (at least visually in the viewer) - and possibly on output too. Vimeo will then ALSO add some color to it --- so, I can certainly imagine that my settings are part of the problem... 

      Consider seeing how dropping the saturation to 87% feels.

    I just registered to upvote for this issue. I am also affected by this issue and hoping for a soonish fix. Let me know in case I can give more details on my equipment.

     

    My color is totally off in every recorded video from HDMI Capture to ScreenFlow Project. Skin color looks like I got sunburned. This is before exporting even. Same sequence recorded in Quicktime looks fine though.

  • I have exact the same problem... The recordings in Screenflow look reddish. No need to export them... Its direct after screen capture the images of my Cameras (Sony RX100, Sony AX100, BMPCC 4K...) all look reddish as hell. As there is no fix for this since over a year.. I just upgraded my Camtasia to 2020. There colors are fine.... but they have an Audio lag of 0.3 seconds... which screencast doesn't have... Any idea how to get a program without color cast or audio lag....

      Frank Werner Re camtasia: we bought that to test too - but even on our first tests the audio quality was low and compressed and the playback was all choppy --- not to mention the interface and workflow are not hot. So far - even with the many critical problems with ScreenFlow - it's still 20x better. There is basically no competition in this space. Next step up would involve the camera output separate and screenflow for the screen - and -- then to put it all together in a fully-featured editing suite - but that will probably 10x the work.

      between the problem of a difference in audio capture for a video capture that cannot be corrected, I am left with the audio problem. The audio you just separate it in the edition and move to correct it. What happens with the Screenflow video does not have enough correction, starting with the super problem of having to have a color in the preview window, then another color and when exporting another one it appears. That is, you would have to have your life dedicated to that. I expected the life of this team to be dedicated to this, but I have already conformed to the understanding that I have to go after other possibilities.

      I have been using Camtasia since this problem arose. It gives less headache.

      Elias Coutinho de Oliveira  Well - my computers must not work with Camtasia - because it just seems terrible. I'm talking with them about it.

      My full-time job is now to QA for Telestream and TechSmith. Least favorite job ever.. and it doesn't pay very well... like negative $200 an hour.

    Seeing the red contrasty shift in Prores export from camlink capture — will resort to using quicktime for capture I guess
