ffmpeg -i input.mxf -pix_fmt yuv420p -c:v libx264 -preset fast -crf 22 -c:a aac -b:a 192k -movflags +faststart test.mp4

Original Question

trying to convert a large MXF (well, large for its playtime 1.1GB, 2:36 minutes) into a reasonably small MP4 file to host on OneDrive (business). I can convert it with, for example:

ffmpeg -i input.mxf -c:v libx264 -preset fast -crf 22 -c:a aac -b:a 192k output.mp4

And it does play in mediaplayers on my computer, but in OneDrive in Chrome I get the error message: "Sorry, there was a problem loading the video."

Now when I take a random MP4 testfile, convert it via the above command and upload it, it plays without issue.

Any ideas?

If you need something to investigate (terminal output, file info..), let me know.

Thanks!

Edit:
Here's the log for:

ffmpeg -i input.mxf -pix_fmt yuv420p -c:v libx264 -preset fast -crf 22 -c:a aac -b:a 192k -movflags +faststart test.mp4

For widespread MP4 compatibility, video should be H264 with 4:2:0 subsampling, and audio should be AAC-LC. Additionally, moving the metadata to the front of the file is recommended for quick start of playback but isn't strictly necessary.

So,

ffmpeg -i input.mxf -pix_fmt yuv420p -c:v libx264 -preset fast -crf 22 -c:a aac -b:a 192k -movflags +faststart output.mp4
