Joining the Videos While Preserving
First create a text file (e.g. filesToMerge.txt) with all the chaptered video files that you want to merge into a single video e.g.
| Code Block |
|---|
file GH010097.MP4
file GH020097.MP4
file GH030097.MP4
file GH040097.MP4 |
Next, check the streams in the video files.
