Bottom line is that when I do these conversions, I really don’t want lose the time stamps in them. It would change the date to something like 1109212 Aug 2nd. Exiftool was create but sometimes I just wouldn’t work. But, sometimes that doesn’t work with videos, so I would airdrop them to my iPhone, use an app called Metapho to change the dates, and then airdrop them back. Originally I was using exiftool in terminal. Having trouble keeping the time stamp that I put into the videos. I just want the files to take up less space and with minimal or no quality loss.

I don't want to change any of the fancy settings.

The file isn’t compatible with QuickTime Player.' The video will play with VLC but the icon is weird and when I try to open it with QuickTime, I get the error: 'The document “output.mov” could not be opened.

I've tried this: ffmpeg -i input.mp4 -c:v libx265 output.mp4įfmpeg seems to take a long time and the output seems to be about the right size. All I want to do is convert videos in my library to HEVC so they take up less space. I see that there are a few questions on this subject but I am still getting errors.
