Video Rendering failed from iMovie
I did reinstall both macOS Catalina and iMovie, but iMovie still keeps fail to convert and message "Video rendering error: -50 (iMovie error -50: renderVideoFrame failed)".
I tried many ways to try to solve try it, included :
- cut clips a bit shorter, copy the whole clips and paste into a new clips,
- tried to pressed "option+Command+open iMovie" then deleted the "preferences",
- pressed "option+command+R+P" to clean everything
- Reinstalled System
- Reinstalled iMovie
Above options were not work. I have already talk to Apple Engineer in Singapore and he also saw my screen about how to fix it, but he can not help me to fix the problem. Last, my iMac was replaced the HD by Apple due to error issue on Jan 2020. However, we have finding different problems again after it was replaced a new screen.
Anybody can advise to me? Many Thanks!
