I'm trying to use ffmpeg to break long video files (circa 60mins) with the following requirements: 30sec chunks (fairly exact chunks, no frame loss between chunks) Transcoded to html 5 compatible video Filenames in time code format eg first chunk 00:00:00 second chunk 00:00:30 etc (it would be great if first chunk time could be specified by this would be the cherry on top!)

So far the closest working script I got was

    ffmpeg -i VID_20130417_140328_555.mp4 -s 480x360 -map 0 -keyint_min 10 -vcodec libx264 -g 60 -vb 500000 -strict experimental -acodec libfaac -f ssegment -segment_list out.list out%03d.ts 

This segments the file into the correct format but I can't control duration or naming.

Any help greatly appreciated.

Refer to -segment_time in the segment muxer docs. –  LordNeckbeard Oct 10 '13 at 20:57

Also, you should always include the complete console output, you don't need -strict experimental, and -f ssegment looks like a typo. Stack Overflow is off-topic, so I voted for migration to Super User. –  LordNeckbeard Oct 10 '13 at 21:00
