AVS and VFAPI: No image produced.

So after doing some research and finding the AMV guide on this site, I've decided to walk through the whole darn thing so I can produce AMVs at a nicer quality instead of stumbling through a bunch of things I don't understand. That said, I've finally reached the point of editing and, using Vegas, have to go the VFAPI route. My avs script contains an MPEG2SOURCE statement, a Telecine statement, a Decimate statement, then a ConvertToRGB32 statement. All well and good. Weird thing is, VFAPI's output file doesn't show any video (i.e. black screen) unless the RGB conversion is set above 24. Trying not to sacrifice quality, has anyone else encountered this issue? Is there a fix, or am I going to have to bite the bullet and move down to RGB24?

Some other useful info:
-Not using AMVApp. Took the AVISynth filters from AMVApp, however.
-AVISynth 2.56 Alpha 2 (Release Date: 9/19/2007)
-VirtualDubMod 1.5.4.1
-Using K-Lite Codec Pack 3.8.5 Full

Thanks for all the help.

Since I can't seem to find an edit button, have to correct that the output avi doesn't function correctly when the RGB conversion is at 24 or below, hence not being about to use ConvertToRGB32(). Whoops.

The VFAPI method only works with RGB24. You're not losing any quality, since the only difference between RGB24 and RGB32 is that the latter has an alpha channel.

Ah yes. It seems a mix of fatigue and my perfectionist nature were getting the best of me. Thanks again.
