Is there anyway to turn a regular 4:3 captured avi file to

[jeremymiller]

TMPGenc encoded 16:9 mpeg file? I changed the aspect ratio to 16:9 before encoding in TMPGenc, but the figures in the end product mpeg file looked squashed. Thanks.

I am trying to do the same thing myself... I have worked out that any Divx files without black bars need to be stretched vertically by 25%. Virtualdub can do this, so you can either re-encode (not recommended) or frame-serve to Tmpgenc (fiddly). There must be a way to do this from within Tmpgenc... anybody?

ok I am lost here...can I get a little more detail?

is the source 16:9? I know you said the source was 4:3, but does it have black bars? if there are no black bars and your video was "formatted to fit this screen" (namely, pan and scan) I don't think you can just "make" it widescreen...the stuff on the side that p&s cut off can't be gotten back...and if you do, it will look stretched, as yours did
good luck

*Video* settings are different to *advanced* settings. Under *advanced* Source aspect ratio should be either 4:3 or 16:9 to suit the source (eg DVD), unless it's of something like a PC-originated format such as DivX, when it should always be 1:1(VGA). Generally you should start out with a Video arrange method which includes *keep aspect ratio*, unless you have a good reason not to. Under *video* setting, aspect ratio is usually set at 4:3 in the standard templates, but you can unlock these to give a result more appropriate to your display.

I think what jeremymiller wants is to vertically stretch a 4:3 AVI file so that he can set his TV to 16:9 mode and watch a large picture with not too much loss of detail, rather than just blowing up the picture and seeing every single macro-block.

I have had some success at this, frame-serving from Vitualdub. I take back what i said about it being fiddly, heres a sample (no audio):

Thank you for the replies. Could you briefly describe how you did it in Vdub?

i think banjazzer just gave you instuctions for tmpgenc. vdub cant save a file as .mpg. tmpgenc has support for both avi and mpg but it can only save it as an mpg file.

I thought we were talking about converting avi files to mpg, for which you only need TMPG.
