Usually when I drag a video from Zoom or my Cannon camera, the preview will play back at full speed. However, when I drag in a video from my cell phone, it only gets ~3 FPS. (Interestingly, the video plays at full speed in VLC.)

I have tried playing with the frame cache and proxy settings, and while it helps with a section of video that has already been played without av-sync, this does not answer the question of why my cell phone video decodes slowly.

Is there some type of preprocessing or transcoding that can be done with something like ffmpeg before importing it into Blender?

If you recommend transcoding, then what settings would you use to minimize recompression lossyness?

I am using Blender 2.83 under Linux.

Thank you for your help!!1
