Actually, an aspect ratio of 16:9 is correct. It's the video display that is wrong (for reasons unknown to me - might be a decoder problem). The switch occurs in the sequence header that precedes frame 21 (I). And while it's debatable whether the B frames (19 and 20) have 4:3 or 16:9 aspect ratio - due to frame reordering, they appear logically before, but physically after the I frame -, the decision is clear for the P frame (18) which always uses the old aspect ratio. > Feature request: > The ad scene ends with frame 4 and so I set the start marker to frame 5. > Unfortunately it was send by Pro7 as 16:9 for a short time and therefore > the cut will contain a 16:9 and 4:3 mix. :-( I know.

Due to the "keyhole surgery" approach dvbcut uses, most of the video data is just copied 1:1 from the input to the output. The program doesn't even look at the data. We would have to parse the video stream (again) and copy it piece by piece in order to change the aspect ratio on the fly. > The workaround is using ProjectX, set aspect ratio to 4:3 in the video > menu, demux and remux. > But this is very annoying...
