Advice on editing .ts files

elsmandino · 08-01-2017, 07:47 AM

I have a mixture of SD and HD movies that I have recorded over the years.

I would really like to cut all the adverts out as well as stripping away unneeded audiotracks (like the narrative that is often provided for those with poor eyesight). To preserve the subtitles would be great, but I could live with losing that if absolutely necessary.

What program do you recommend?

Also, what container should I use? Should I leave the output as .ts or perhaps repackage the output in something like mp4 or mkv?

I believe ffmpeg will handle ts files.

The first thing I do when working with .ts (transport stream) files is to run it through ffmpeg and put a file header on it with a working time index.

Code:

ffmpeg -i file.ts -c:a copy -c:v copy file.mp4

Then you can edit file.mp4 any way that you wish. If you for examples want to edit out the commercials.
Made up Examples:

Get video from 3:00 to 8:34 in the video

Code:

ffmpeg -ss 00:03:00 -t 00:05:34 -i file.mp4 -c:a copy -c:v copy out1.mp4

10:00 to 20:26

Code:

ffmpeg -ss 00:10:00 -t 00:10:26 -i file.mp4 -c:a copy -c:v copy out2.mp4

22:00 to 30:38

Code:

ffmpeg -ss 00:22:00 -t 00:08:38 -i file.mp4 -c:a copy -c:v copy out3.mp4

That will give you out1.mp4 out2.mp4 and out3.mp4

To put those together for final video:

Code:

touch file.txt

Either edit file.txt in your text editor or redirect to it

file.txt

Code:

file '/path/to/out1.mp4'
file '/path/to/out2.mp4'
file '/path/to/out3.mp4'

Code:

ffmpeg -f concat -i file.txt -c:a copy -c:v copy final.mp4

or

Code:

ffmpeg -i "concat:/path/to/out1.mp4|/path/to/out2.mp4|/path/to/out3.mp4" -c:a copy -c:v copy final.mp4

.ts steams are mpeg2 video and aac audio. If you want to reencode that to something different or smaller then you can. Look at the man page for ffmpeg.
You will want the -c:a and -c:v switches.

if you want more, ask.
