Video Export is Black

Upgraded to High Sierra and ScreenFlow 7.1.

I uploaded a video today to YouTube. The video portion is completely black, but the audio is there. It shows properly in ScreenFlow, but the export to YouTube is no good. This happens on my full video (50 min.) and my short video test of just a few minutes (see, https://www.youtube.com/watch?v=mzTASEhLnB8&feature=em-upload_owner )

I tried an export the same video using the automatic normal setting, and it is also a black video with good audio in the resulting mp4.

I am using video files from my Q4 Zoom camera (.mov) which has worked for the past few years.

As a second test...

I ran a test recording directly using Screenflow using my built in eyesight and audio works fine to convert to YouTube and exporting to mp4.

It seems the problem is with .mov files brought in from my Q4 zoom. These play fine on their own, and inside Screenflow, but the export file and publish to YouTube both fail.

Please advise.

This is the reason I asked for the previous version. I must have been so pissed off that's why I never saw that previous download link which I now see and I've downloaded Screenflow 6.

    so here's a zip Screenflow project that shows that Vibrance didn't work.

    Now here's what I did.

    I created a first Screenflow project to record from screen, then I exported to MP4.

    Then I create the above Screenflow project and created a new document not from recording the screen, then I imported into the media library the MP4 that I exported from my first project. Let me know or others let me know if you see a video playing.

    So, recording from screen there's no problem with me, it's when I import MP4 videos into Screenflow, that's where I'm having an issue.

    I took that exported MP4 from that first Screenflow 7 project and imported in a new Screenflow 6 project and what do you know, it works.

    I'd like to chime in as well here, 

    Black export (odd little bits of colour here and there)

    Vibrance filter to 0 does not solve the issue

     

    I am bringing in MP4 files externally and rendering in screenflow as mentioned by gabe garza above that is where they are also experiencing an issue.

     

    New Doc > Import MP4 > Export h264 

     

    Exporting from Quicktime h264 works fine

    Recording screen and exporting h264 works fine

     

    I am running a Nvidia Geforce 1080 on OS Sierra

    Bryan i have a Geforce 780 ti actually 

    Just further note - i just tested a few different clips

     

    Importing H264 and exporting > fail

    Importing x264 and exporting > fail

    Importing Apple Pro Res and exporting > success

     

    so there is something up with the reading of the x264/h264 codec when exporting

    Perhaps the Vibrance workaround does not work for everyone. Maybe it depends on the NVIDIA GPU version. We are working on the fix.

    We may need to keep track of the NVIDIA GPUs where Vibrance set to 0 does not work. Sometimes an issue can have variations.

    Bryan  has 780 ti
    What GPU do you have gabe garza ?
    Also noting that I see your dock icons in both your projects on my Mac with AMD GPU regardless of Vibrance filter. Dock on blue desktop.

    >Perhaps the Vibrance workaround does not work for everyone

    If it doesn't work for everyone then you're looking at the wrong solution.

    Look at why in Screenflow 6 importing a MP4 works fine but when you import a MP4 in Screenflow 7 it doesn't work.

    On the same computer which obviously uses the same chips GPU and CPU, your theory of NVIDIA GPU's being an issue goes out the door.

    In the meantime I'll keep using Screenflow 6 which just works.

    gabe garza We can confirm the issue is NVIDIA GPU related. That seems to be a constant. 6 and 7 are different and may handle it differently and we are investigating how to fix. Sometimes one change or improvement impacts other things.

    CraigS just like to highlight that this has not resolved my issue.

     

    MP4s with H264 or x264 codec still rendering out BLACK for me on 7.1.1

    Bryan Please test with a new document just in case the issue is carrying over from an older document. You don't mention your Mac model but if you're using an older Mac Pro Tower we only support the official GPUs Apple certified for the machine.

  • Rory Maloney The Vibrance work around worked for me.

    I had imported videos captured from my iPhone into Screen flow 7.2 and it was exporting Black video (audio fine) no matter what I changed.  I am running OS Sierra

    Aaron Trimble The issue should be resolved in 7.2 (Please confirm version). Also confirm version of Sierra (10.12.6?). What are your computer specs including GPU?

  • On screenflow 6. Same issues still. Workaround worked. Sad and disappointed in the product in general and won’t be upgrading to 7, as it seems the issues are there also! 

    Seems a deeper seeded issue than tech expected. And one more with compatibility with OS versions than Screenflow versions.

    This issue was fixed with ScreenFlow 6.2.4 and also fixed in recent version of  7 (now at 7.2). The reason why no one has posted in a month is because the issue is fixed. See 7.2 or Previous Version for 6.2.4 at the top of the link.
