Cut points are not on keyframes

[Enrik]

I'm trying to cut an mkv video file with Avidemux 2.6 and I don't want to re-encode. I want an exact copy, so I used:

Video Output - Copy
Audio Output - Copy
Output Format - MKV Muxer

I selected A and B (as In and Out keyframes) but when I try to save the video I get this:

The video is in copy mode but the cut points are not on keyframes.
The video will be saved but there will corruption at cut point(s).
Do you want to continue anyway ?

I want the cut points on keyframes without re-encoding, what should I do?

cutpoints are on the up and down arrow keys. you can see what kind of frame I P or B ons screen.
If you use the left and right arrowkeys you get the P and B frames as wel.
Make sure you always end on a I frame by using the UP and Down arrowkeys

Thanks a lot, Bonnevue.
