[FFmpeg-user] [N-46469-gc995644] Slice at key frames?

[Gilles]

Hello

I have a question about slicing MP4 videos.

I need to slice a 1h30 movie into two files: 60mn and the remainder.

I was wondering if ffmpeg will slice at keyframes when using the
options "-ss" + " -t", or if I should first view the movie in an
application to retrieve those infos and then use an alternative option
in ffmpeg to tell it to start/end at keyframes?

Thank you?
