Ok, you guys obviously know a heck of a lot more about this stuff than I do, so I hope someone will read this who knows the answer.

I have a movie on 2 CDs that is good quality AVI with Fraunhofer IIS MPEG Layer-3 Codec audio. However, it was encoded in 480x208 ratio when it should have been NTSC 352x240. All I want to do is change the ratio and be able to burn it back onto 2 CDs.

I have NanDub 1.0rc2 and TMPGEnc 2.53. The movie was encoded at 1150 VBR.

I have tried several times and several ways to do this and I can manage to change the aspect ratio, but either there is no sound or the file is huge or I get errors or lockups in WMP and PowerDVD trying to play the output.

If you answer this, please be very clear and simple; I am not very familiar with video encoding. Do I need to separate the audio from the video first? What format? Do I also need to extract the video without audio and then put them back together? With TMPGEnc? Is it possible to change the ratio in NanDub, or do I need to use VirtualDub or something else? After I change the ratio, do I need to (how do I) crop the black borders for wide screen?

Any help appreciated.

:confused:

If you just want to play the .avi on your computer, you may want to look at zoom player, which can change the aspect ratio during playback. This means you won't loose any quality by re-encoding.

If you really want to re-encode it try looking at doom's conversion guides here: http://www.doom9.org/conversionguides.htm

You don't want to change it's aspect ratio but it's resolution ;). AFAIK TMPGEnc does this for you automatically ( adds black bars and resizes the image ). Just go into settings and type in 352x240 as resolution. Aspect Ratio nearly always is 4:3. The only exception is if you have a DVD. But AVI ALWAYS has a 4:3 aspect ratio ( what makes it look 16:9 like the DVD is the resolution ).
