Camera very Laggy

Hi; I have just installed Screenflow 10. MacBook Pro (2020), Logitech C920 Webcam, MacOS Big Sur 11.4

The camera is very laggy - only occasionally updates the recording. 

Screenflow 9 continues to be fine, as do other apps - Zoom.us / etc.

Is this a known problem? I couldn't see it being reported.

Thanks. Bob

    We should have a fix for this very soon.

    • CraigS This may be telling you something you already know, but I used the inbuilt camera on the MacBook Pro and it seems fine.

       Yes, this issue seems to be specific to external USB devices. It can be laggy/low frame rate and/or small squarish frame sizes as well. Fix coming soon.

  • having the same problem with a new Mac Mini. I'm currently using a cheap webcam, which works fine and records fine with all other apps, but when recording with Screenflow, it acts like an old webcam from 2010-----patchy and scratchy movement. I'm hoping to purchase SCreenflow, since I haven't had a Mac for a long time and this was one application that I missed a lot. Will this be fixed?

    • I plan to get a better webcam, but am shopping around for that.

  • I have just contacted support with exactly the same issue. iMac 4Ghz, 32gb RAM, running Big Sur 11.4."When I start recording from Screenflow 10.0.0.2 (webcam recording, screen recording, USB mic recording enabled) I see NOTHING on screen- no Screenflow interface. I record blind. When I review the recording I see horrific lag in video recording although the audio is clear. I have reformatted my Mac and have created my users folder on a different volume on same internal drive. Could this be in an issue? I have a screen recording showing the issue but not sure if a 360mb upload will be allowed in the forum.

    Really wish I had not deleted Screenflow 9 as it ran perfectly!

  • I have the same problem regarding the Logitech C920 with Screenflow V10.0.2. I hope the fix is released ASAP, as the C920 is much better than the built-in camera on my IMac.

    The update didn't fix the issue for me but changing the order on the inputs and placing 

    the web camera after the screen seems to have sorted the lag.
