View Full Version : Controlling Aspect Ratio with DivX?

THis has got to be a stupid question that's been answered many times before, but I sure can't find the answer.

I'm trying to rip a DVD to AVI. It happens to be a PAL 4:3 DVD, and I'm in NTSC land with little experience with PAL.

I've decrypted the VOBs to my hard disk, created a DGIndex project file, written a basic AVISynth script (including smooth deinterlace and framerate doubling), opened that script in Virtual Dub, and saved to AVI using both XVID and DivX (6.4.051). I like the encoding results better with DivX, but the aspect ratio appears to be off. In XVID setup I set the pixel aspect ratio to "PAL 4:3" and the result is just as tall but wider than the DivX version. I don't see anything in the video that I can use as a reference to figure out which is correct, but the XVID version looks better to me and I did set the aspect ratio in XVID ...

I can't find anyplace in DivX where I can control that aspect ratio, but there's gotta be something somewhere! Help? Please?

but there's gotta be something somewhere! Help? Please?Yes you can use an application called MPEG4 Modifier (http://forum.doom9.org/showthread.php?t=78050) to add "aspect ratio signalling" (to any ISO compliant MPEG-4 stream) to alter the shape of your encoded pixels...

Hi!

If you're intending to play your .AVI on your PC, there's no need to convert from PAL to NTSC...

True. But I'm not converting to NTSC; I'm maintaining the frame size and doubling the frame rate to 50.
