For example: With XAVC the progress bar reached 100% but the elapsed time kept going because the conversion was not done, until a minute+ later. The remaining time and elapsed time are rarely accurate. I was surprised that even H.265 didn't take long on my old system.Ī couple of things: in DNxHD for example, NTSC presets appear to be missing, and only PAL (25, 50fps) are available judging by the the codec specifications Ĥ5, 145, 220, and 220x presets are missing for example (1080p30 and 720p60). I converted an XAVC-S file to a variety of formats: ProRes, DNxHD, DNxHR, XAVC, H.265, AV1, AVC-Intra 100x XDCAM, etc and it all worked perfectly. To summarize, ffmpeg gives me unusable subtitles with display durations of 0, while MP4Box gives me usable subtitles which however end too early.One more update. Unknown box type 6F660000(73/100)Ĭonversion failed (BitStream Not Compliant) When running the above MP4Box command, I get the error messages Also, the font information is gone, but I don't really care about that. MP4Box: 'mp4box input.mp4 -srt 4' outputs the following:Ĭompared to ffmpeg's output, the subtitle durations are now correct, BUT the subtitle file abrupty ends more than 40 minutes before the end of the movie.

Note that all of the subtitle durations are 0, which makes them unusable.

The only difference is that the final entry (4822) is not included in XMedia's output file. LosslessCut similarly recognizes the stream (tag 't3xg', codec 'mov_te') and also fails to extract it.įfmpeg: 'ffmpeg -i input.mp4 subs.srt' and XMedia Recode output almost the exact same file: My MP4Box GUI recognizes the subtitle stream (file information: 'Text - Timed text'), but fails at extracting it.

MKVToolNix GUI does not recognize the subtitle stream. Here is my experience extracting the subtitles with various software: Here is a mediainfo excerpt:Ĭodec ID : mp42 (mp42/isom/iso2/iso5/dash/avc1/dby1/mp41) I have an MP4 file 'input.mp4' which has a tx3g subtitle stream that I would like to extract, ideally as an SRT. This is related to a separate issue that I'm having but I wanted to ask a new question so as not to conflate things.
