Avidemux cannot cut a video into the correct length
« on: October 10, 2017, 03:31:32 AM »
Ive noticed that sometimes, Avidemux 2.7 cannot seem to cut a video into the correct length.

E.G. Lets say that I have a 1 minute long video and i want to cut it so that the video is only from 00:10 to 00:20. For some reason, Avidemux often includes "extra" seconds outside the 00:10 to 00:20 range. So the resulting video actually contains footage from 00:05 to 00:20, or something like that.

I am cutting the video using the "A/B" markers.

See the screenshot. Why does it do this?

I tried creating a bug ticket on sourceforge but nobody replied even after several weeks, not sure if anyone checks that tracker anymore.

Using Copy mode (no re-encoding) requires you to make the editing points on keyframe, indicated by I-FRM.
Only selectable with
- keyboard up or down arrows
- Go to previous intra frame (keyframe)
- Go to next keyframe.

that is all to it.
