changing aspect ratio after encode?

[tahngarth]

I goofed when encoding and made a movie that's supposed to be 16:9 a 4:3. I don't know if the ratio is only in the header or what. anyway, any way I can fix it without reencoding? or even adding black bars, but I'll be watching the other post for that. thanks

I've never tried this, and it may (probably) won't work but I noticed that in the program MPEG Sequence Maker there is a pull-down menu for the display aspect ratio with selectable options. You could try demuxing your mpeg in TMPGEnc (mpeg tools menu), then open the video file (.m1v or .m2v) in MPEG Sequence Maker, select the desired aspect ratio, and select Start. As far as I know this just adds/changes header info in the stream. When its finished processing the video file, go back into TMPGEnc and re-mux your video and audio files back into a mpeg file using the appropriate VCD/SVCD template.

Edit - Did you mean you selected 4:3 as the source aspect ratio, or as the aspect ratio for the encoded mpeg? I think for VCD/SVCD you have to select 4:3 for the encoded mpeg.
If you have a 16:9 movie, you would select 16:9 for the source aspect ratio, and 4:3 for the encoded mpeg so that TMPGEnc adds the black borders. If you selected the wrong source aspect ratio I think you will have to re-encode.
