How do I get widescreen in my DivX export?

[Niber]

Hi,
I've made a movie with a DV cam and it's all finished.
I have given out the movie in DVD export where it works perfectly.
I also want to make a internet version of it, and exporting the DV movie in Vegas to DivX works pretty good,
BUT, it thinks the movie is 4:3.
Every movie-player I open it with it displays 4:3 while it should display 16:9,
In some players I can manually say it should be 16:9 and it looks perfect but I don't expect my viewers to do this.

How can I export to DivX and make sure players recognize it as 16:9 material?

DivX doesn't support PAR/DAR flags. You can set it after encoding with MPEG4Modifier, but I don't think that the DivX codec supports PAR resizing so it would playback 1:1 anyway. So your best bet would be to resize before encoding.

I cannot open my movie with that app, it says it doesn't support OpenDML.

hmm with Resize you mean to resize the height pixels so the pixel aspect would be 1?
yes I guess that would work, a bit worse quality but I guess I can live with it.

Your movie is over 2GB's? If not then you don't need OpenDML. If you are worried about quality then you could resize horizontally with a nice sharp resizer, like lanczos so as to keep the vertical res. However you aren't really gaining any more detail and you are increasing the pixel count.

hmm no, it's not. ok no OpenDML..

Well yes, this worked.
There is one problem thought:
I can export 720x576 (DV 4:3) but when I change it to 720x405 (which would be 16:9) it says it cannot export with these settings.
It seems to only export as high as 720 if I use defualt DV res.
however if I lower the horizontal pixels also (like 640) I can choose whatever height I want to, so that worked. (640x360)

thanks, dude

You can't have 405 as a vertical res. For YV12 it needs to be divisible by 2 (MOD2) and for MPEG4 ideally the vertical resolution should be mode16. Horizontal res needs to be mod4 and once again should be mod16.
