I am getting a error at the very beginning of the encode save (nth pass) with VDub. I did search the forum, and found one post on it, but no good explaination. My resize is set to 640x480, which is in VDub, not DivX. I have tried almost everything I could think of. I still get that error. Source image format is unacceptable (error code -2). Would the bidirectional, quarter pixel or GMC cause this? I have tried the original res (720x480). Depth color is set to 24bit. Video is set to 'full processing' and I've tried audio at 'direct stream' and 'full compression'. I have tried precise bilinear, precise bicubic, lanczos 3. I have checked and double-checked that my res is divisable by 16 (640x480 and 720x480). I have searched this forum and the forum over at doom9.org. Nothing, and I mean nothing, that I have attempted has worked. I know this topic is posted over and over again, and I apoligize for posting this one. But none of the advice has worked. I am at my wits end here. The movie that I am encoding is Matrix-Revolutions, incase anyone has any experience with that movie.
