I want to cut long videos into several smaller parts without changing any format and metadata from the original video.

Original

I used these commands

ffmpeg -i input -ss 00:00:05 -t 100 -c:a copy -c:v copy output

ffmpeg -i input -ss 00:00:05 -t 100 -metadata "major_brand=mp42, minor_version=0" -c:v copy -c:a copy output

ffmpeg -i input -ss 00:00:05 -t 100 -map_metadata 0 -c:v copy -c:a copy output

ffmpeg -i input -ss 00:00:05 -t 100 -map_metadata 0 -b:v 460k -c:a copy output

Result

but still get different results from the original video.

Is there another command that I can use for cutting the video with metadata results identical to the original one ?

Thanks

  • Which metadata do you wish to preserve? – Gyan Aug 18 '16 at 6:42
  • @Mulvya i want to keep Major Brand and minor brand, is that possible? and could you tell me what the meaning of handler_name :IsoMedia File Produce by Google. Thanks – MiraClee Aug 19 '16 at 7:04

FFmpeg only allows you to alter/override the major brand, not the minor.

Command is

ffmpeg -i input -ss 00:00:05 -t 100 -brand mp42 -c:v copy -c:a copy output

MP4box will allow you to override both.

mp4box -brand mp42:0 file.mp4

If you want to change the handler name as well, use

mp4box -brand mp42:0 -name 2="IsoMedia File Produce by Google" file.mp4

(2 is the track index i.e. the 2nd track)
