Ok, More details needed I guess. I Rendered the exterior scene AVI in Bryce USING Full Frame Compression, Imported that AVI To Poser as a background image in Pro Pack. Rendered that animation in Full Frame. then Opened the file in MGI VideoWave 4 and added the audio track. When it produced the final DivX & MPEG AVI things went dark. I then Imported the full frames from Bryce AND The Audio track (WAV) file into Poser and Rendered it straight to DivX. I'm going to try again using the basic Microsoft Video 1 Codec. I'm thinking it's some compression thing for sure even though I have the DivX and MPEG Codecs set for 100%. Heck! It might be just that adding the audio track that's doing it. As this animation is a 599 frame Poser animation each new render is taking 8 hours. I think I'm gonna have to start doing clip renders from the file til I find the right settings.
