I'm trying to split a video (50-100Mo) into several small clips of a few seconds each. I don't need re-encoding, hence my use of codec copy
.
However some of the resulting clips don't have any video.
Fast but no video in some files
ffmpeg \
-y \
-i ./data/partie-1:-Apprendre-300-mots-du-quotidien-en-LSF.jauvert-laura.hd.mkv \
-ss 0:00:07.00 \
-codec copy \
-loglevel error \
-to 0:00:10.36 \
'raw/0:00:07.00.au revoir.mkv'
I also tried -map 0 -c copy
, -acodec copy -map 0:a -vcodec copy -map 0:v
or no option related to codec.
Slow but complete
No argument related to audio/video encoding, it's working but pretty slow.
ffmpeg -y \
-i "$SOURCE_VIDEO_FILE" \
-ss 0:05:37.69 \
-to 0:05:40.64 \
-loglevel error
'raw/0:05:37.69.pas la peine.mkv'
Question
How do I split a video into small chunk ~2-4s
when I have no need for re-encoding?
