Otherwise your audio will be out of sync. If you are editing a audio file, run Audio→Build VBR Time Map before you do any editing.

Smart copy will work in that case, but not with streams containing B-frames. When copying, you must make sure the first frame you copy is an I-frame when pasting, the frame after the insert point must be I-frame. You can confirm the start and end edit positions the frame displayed at the bottom of the screen, under the Selection section:įrames can be copied and pasted by doing Ctrl-C and Ctrl-V.

Use the Mark B B buttons to set the end of what you want to edit. Use the Marker A A button to set the start of what you want to edit.

Mathematically speaking, the set of frames saved is (A,B). Every frame from marker A to marker B will be saved, excluding the frame at marker B. You can save part of a stream by going to File→Save→Save Video. So, for example, if marker A is at frame 0 and marker B is at frame 10, then you set marker A to frame 20, Avidemux will actually put marker A at frame 11 and marker B at frame 20. If you try to set marker A to a frame after marker B, Avidemux will set marker B to that point, and marker A to the frame after where marker B used to be. Obviously, marker A can't come after marker B.
