I don't htink you can (DV has a pixel ratio of .9, normal pictures have a ratio of 1.0. If you load a 720x480 pic into Vegas it won't look right, but at 654x480 is will).
However, I don't use VV for rendering image sequences. I'd recomend TPGenc. Much much faster & more options!
You can load any video file into TMPGenc (2.5, don't know how 3 works). Then, under the file menu, there's an "output to file" option. Just type in the filename you want & select the file type (stilltype) and it'll do it. :)
no, don't think so. I think there may be scripts for that in Vegas though. Try a search for that (I remember it a while ago, but not recently). I've always just sped upmy footage (prety much same effect).
Why do you need 720x480? 654x480 is the actual size of the NTSC frame with a 1.0 pixel aspect ratio. These pictures will fill the video frame completely.
Those are (technically) wrong. I'm not sure why the snapshot in Vegas is 720x480 (there may be a reason, but I never use it). But, you CAN use 720x480 pics in Vegas, but you will need to manualy change the aspect ratio of each picture to 0.9 to get it to look right. With the 654x480 doesn't need that change.
The TMPGenc thing is wrong. Some NLE's (ie premiere) use the picture size (widthxheight) to determine the ratio, vegas uses the actual pixel ratio.
Infact, here's an idea. Use a different capture program (like iuVCR that I use) & you can tell it what FPS rate to capture at. Then you PTT your DV to a tape, then you can re-capture it at any rate you want. No rendering required. :)
