I am having issues with pixelated videos inside of Screenflow. They are not like this when I open them in Quicktime, and if I click around the video it *sometimes* goes away, but when I download the video from screenflow, it *sometimes* downloads with this pixelated issue.
Sorry you're experiencing this. I'd like to help but I need enough detail so we can reproduce the issue.
Version of ScreenFlow?
Version of macOS?
Source of video since it's being imported it may be a codec compatibility issue? For example, Zoom recordings must be properly set in Zoom (they have an editing software compatibility issue).
