Burn in sub while cutting video #285

Closed nobitataj closed 5 years ago

nobitataj commented 5 years ago

Hi, recently I experience a problem when burning in subtitle (soft-sub) and cutting video at the same time. For instance, if I am to cut video from 0:00:30 to 0:01:00 with Handbrake params -H start-at=duration:30 -H stop-at=duration:30, and my input video has a soft-sub contains a line from 0:00:25 to 0:00:35, then my output video will not be showing that line at the beginning, and the whole line will be missing from output video. I tried this with HandBrake GUI, and the same thing happened, so I guess this is HandBrake's issue. The thing is, when I tried using FFMPEG to do the exact same cutting/burning-in thing (ffmpeg -i input.mp4 -ss 00:00:30 -t 00:00:30...), the line was shown for the first 5s of the ouput video (which is what should've been done with HandBrake). My question is, is there any option I can do to force transcode-video to use ffmpeg for cutting video instead of using HandBrake? or any other way for me to achieve my goal? P.S: I've tried -E ss=30 -E to=30, didn't work. Thank you all for your time!

@nobitataj I'm sorry but there's no way to force transcode-video to use ffmpeg instead of HandBrakeCLI as its transcoding engine.

And if this problem is also happening with the HandBrake GUI app, then there's no way to work around it. My apologies for the inconvenience.

@nobitataj OK, I'll close this for now. Just comment here or open another issue if you have more questions.
