@LinusTech Watching this video I noticed heavy stutter in your B roll, wich reminded me of something, I have encountered and solved a few months ago. When I rendered my last vacation video with Magix Vegas 15, there were some parts that stuttered in a very similar way to you B roll. All those parts were shot on Android smartphones (Xiaomi Mi8 and Mi9). With MediaInfo I found the problem to be that the smartphone videos had variable framerate. MediaInfo detected a range from 5 to 30.5 fps, with an average of around 29.93 fps. I was able to convert the video to constant frame rate with mp4fpsmod, wich only adjusts the timecodes of the frames, without re-encoding. After that I could render in Vegas without any issues. Maybe this would fix your smartphone / webcam B roll as well. Stay well and thanks for your awesome videos, U4P
