I have an AVI (encoded with XviD) that I want to convert to MPEG-2 so I can burn to DVDR.

Taken from GSpot v2.21
704x384 (1.83:1) [=11:6]
FPS: 23.976

What do I have to do in a script to bring it back to it's "Anamorphic Widescreen" state? Do I just have to tell my DVD Encoder that it's 16:9 content? Or do I have to do the same thing that I do with tv captures by adding a line like this in the script: BicubicResize(720,480,1/3,1/3,0,60,720,360)

With this Resolution "LanczosResize(720,480)" should be okey... While you encode you must specify, that this is a 16:9-Movie.

And while this is NTSC with 23.XXX frames/s it should be telecined. But this is something what i can not say exact because i have never worked with NTSC-Movies...

You have to add borders to your video, so it is 16:9. Then you resize to 720x480 for NTSC.

try something like this:

Addborders(0,1,0,1)
LanczosResize(720,480)

Make some tests with round objects in the picture, to see if its okay.

May I ask why to AddBorders with such small borders? 0,1,0,1 is hardly adding borders, is that to correct a slight AR issue from the XviD?

in this case you are right your video is nearly 16:9, but if you have cinemascope-material with 1:2.x for example, then you have to add borders.

Hi-

This is a job for FitCD (http://shh.sysh.de/fitcd.html). For a 704x384 .avi to be encoded to a 16:9 DVD following the ITU standard, it's showing:

LanczosResize(720,466)
AddBorders(0,8,0,6)

although I think I'd change that 6 to an 8, and the 466 to 464. If you want to AddBorders to allow for your TV's overscan, then something like this will work:

Crop(2,0,700,384)
LanczosResize(688,448)
AddBorders(16,16,16,16)

If not following the ITU standard, then:

LanczosResize(720,478)
AddBorders(0,0,0,2)

which is what hanfrunz said (sort of). Or don't AddBorders, and make the 478 into 480. Lots of choices.

yes, a lot of choices. That's why you always should check with your eyes :) And we don't know how the xvid was resized...

Would posting some pictures of the source XviD, or posting a sample of the actual XviD AVI help? I can do that... let me know.

yes, of course. try to find some pictures with round objects like wheels from cars or traffic lights, faces, ...

Well, for some reason VDub is not saving bitmaps correctly when I try to make pics from single frames of the XviD. Funny, it always worked when I used my Huffyuv captures. If anyone knows how to save pics from an XviD source please tell me so I can post them here...

Here's a video sample instead:

The video was down for a few hours earlier. Now it's up and ready for download again. Thanks.

If in Virtualdub, Ctrl-1 doesn't copy the source video to the clipboard, then you can always use the Print Screen button to capture the entire desktop (while the clip is open in Virtualdub), then crop it in your image editing software.
