The benefit of re-encoding the file is that it will definitively remove any encoding errors. Users/Alec/Library/Application\ Support/FFmpegTools/ffmpeg -i "input.mp4" -c:v libx264 -crf 22 -preset slow output.mp4 There’s a more sophisticated version of the command above which performs a basic transcoding. Fixing more problematic files with ffmpeg What’s great about this command is that it’s almost instantaneous (400x real time speed) and does not re-encode so your output video remains the same generation as the input.

It took awhile to find the code to do this but eventually I did.Ī simple repackaging of the file is this command: I remembered hearing about a zero copy which could make broken mp4’s downloaded from the internet open and play again. mkv video file almost instantlyĮxperimenting with the Submerge ffmpeg preset files made me think more about using standalone ffmpeg (the engine in both ffWorks and Submerge) to clean up these files. Files created from Submerge hard-coded subtitle submasters with 1192 hour time codes after a second conversion in ffWorks also show the correct time code. Subtitles created from the same MDRP masters in ffWorks don’t have this issue – the length is normal, 45 minutes.

Next I tried modifying the presets in Submerge (located at within the app package at Submerge.app/Contents/Resources/Presets but didn’t have any luck changing them enough to be able to create movie containers which weren’t three days long.
No luck, they all showed 11.59.59.45 as the movie length (is that one week or sixteen hours). It’s not a critical issue – the files do play back on our Sony X700 and our Pioneer BDP-450 blu-ray players – but I don’t like broken things so I set out to find out what the issue is.įirst I tried using some of the other Submerge presets to create my submasters with hard subtitles.
The 1192 hour length makes it impossible to use the timeline to scrub (right away one is in blackness).
