Concatenate several mp4 files
I have encoded 12 chapters from 3 DVDs.
Each chapter was encoded using latest Hybrid Linux version 2013.06.16.1, in mp4 containers, and all of them are in the same format: an x264 video track, original ac3 audio track and chapter track.They share the same video PAR and same audio bitrate and channels. I now want to join them in a single file. I tried with MP4Box: Code:
MP4Box -add 01.mp4 -cat 02.mp4 -cat 03.mp4 -new all.mp4 I then tried: Code:
MP4Box -cat 01.mp4 -cat 02.mp4 -cat 03.mp4 -new all.mp4
The video problem is a weird one, since I thought that MP4Box just concatenated the files, and I don't understand why it degrades the encode. Can I change anything in my code to avoid these problems?. Is there another method to join the mp4 files?. My system is Linux Mint KDE 13. |
