I have several MP4 videos that is a mix of hev1 and hvc1 codecs. Some of the playback devices are iPhones. Is it better to tag them as hev1 or hvc1?

 

8 FFmpeg by default makes all metadata from the first input file available to the output file muxer for writing. -map_metadata allows to override that by either pointing to a different input or by telling ffmpeg to discard input global metadata (value of -1).

Doing ffmpeg -i input.mp4 output.mp4 didn't fix it but converting to avi did showing thumbnail and correct resolution. Instead of avi we can change the codec with -c:v mpeg4 to fix it also. I tried -c:v libx264 but didn't work since it already was that codec. So it seems the only way to fix it is to switch codec/format then switch back.

I understand that FFmpeg is a powerful tool for video file conversions. I see online in many places people suggesting it for solutions or getting help in how to use it. The problem is I don't even...
