[SOLVED] [2.7.5] Save list of markers, and use to slice file?

[yetanotherlogin]

Hello,

I'd like to use Avidemux to extract (slice) sections of a file, and then join them into a single file.

Using the A/B buttons, Avidemux only supports selecting one part at a time, so slicing is a bit labor intensive.

Is there a way to...
1. Append the A/B settings to a file
2. Use this file as input to slice and re-encode the original file into a smaller file
?

Something like this:

Code Select Expand

#timestamps.txt
00:00:41.734 - 00:00:50.067
00:35:07.488 - 00:38:11.034
etc.

avidemux.exe -i timestamps.txt -i input.mp4 output.mp4


Thank you.

Don't think select what you need, think delete what you don't.

Thanks. I find it easier to select what I do want to keep.

I'll just use Avidemux to set the start/end markers, CTRL+T, append the infos to a text file, and run ffmpeg to slice and join.

Ctrl+Alt+C Shift+Alt+C copies the timestamp of the currently displayed frame to clipboard.

append the infos to a text file, and run ffmpeg to slice and join.

Please don't forget that timestamps in Avidemux are different from timestamps in FFmpeg at least for videos which contain B-frames. Avidemux uses an unsigned value for time, so timestamps can't go negative. This forces Avidemux to delay all presentation timestamps for videos with B-frames while FFmpeg shifts decoding timestamps into negative while allowing presentation timestamps to start at zero time.
