Glitching problem + mp4 low resolution problem
I edit HD talking heads videos shot on iPhone layering them with screen recordings made with Quicktime on MacBook Pro (.MOV files). I shot my latest iPhone video in 4K and now I have a heavy glitching in the screen recordings I layer on top of it.
I tried this solution (re-encoding the screen recordings in MP4 with matching the source at high bitrate) https://community.adobe.com/t5/premiere-pro-discussions/premiere-pro-glitching-videos-in-preview-and-export-source-footage-fine/m-p/10563339#M222259 and now the glitching is gone, but the resolution of these screen recordings became pretty bad.
How can I maintain the resolution of these videos and solve the glitching problem?
