I believe that this question is not the same as Lossless H.264 MP4 file created from images cannot be played in QuickTime because that question, and its answer, pertains to converting a series of PNG images. The accepted answer does not work in my case. It also suggests picking a non-zero value for crf whereas I want a 0 value.

I need to convert a bunch of MOV files to mp4 so I can import them into Apple Photos. I would like the conversion to be lossless.

I've tried the following command to convert a single file, with crf = 0 so that it is lossless:

ffmpeg -i in.mov -c:v libx264 -crf 0 -c:a aac -map_metadata 0 out.mp4

(in.mov is 400Mb, out.mp4 is about 600 Mb)

ffmpeg completes without issues but Quicktime cannot open the file (the file is incompatible with Quicktime Player), and Photos cannot import it. VLC can open it and playback without issue.

Setting crf to a value > 1 results in files that quicktime can open.

Any ideas?

Log from converting with crf 0

    I suggest you the tool "avidemux" that is a good tool for simple video editing and transcode and also is available on windows, linux and osx – DDS Mar 1 at 14:19

    @DDS That is not a very helpful comment. I suggest deleting it unless you can tell the OP exactly what to do to fix his problem. – slhck Mar 1 at 14:20

    It was posted as comment and not as an answer because I'm not willing to write that much – DDS Mar 1 at 14:22

    He just have to transcode the video... it looked obvious from question itself. – DDS Mar 1 at 14:28
