I got a mp4 video. I just want to split it in 4GB file parts using ffmpeg (to make it writeable on FAT32).
C:\ffmpeg\ffmpeg.exe -i "%NAME%.mp4" -n -t %LENGTH% -codec copy "%NAME%_1.mp4" C:\ffmpeg\ffmpeg.exe -ss %LENGTH% -i "%NAME%.mp4" -n -codec copy "%NAME%_2.mp4"
- The original file's overall bitrate is 9450 Kbps.
- The first output's overall bitrate is 10.1 Mbps.
- The second output's overall bitrate is 8727 Kbps.
I guess that the bitrate of the original video is variable and not equally distributed, is that right ?
How can I fix it (in a batch that would be great)? May I convert first the original video to constant bitrate?
Thanks for help guys !
