First post, please forgive any missed etiquette.
I'm experiencing the same problem listed in the thread linked- however I've absolutely no idea how to resolve it.
I'm making an AMV (honestly, this one's not bad.)- I've rubber-banded (I think that's the terminology) all the clips in which I've changed the speed in some way. Everything appears to be fine- in preview everything plays as intended (doesn't it always?)- but while rendering, the preview box shows black screens in place of any clips that I have sped up, while slowed down clips display properly. When fully rendered, the finished product mirrors this. Audio is not affected by any of this.
Running Vegas 8.0 pro.
Any advice much appreciated.
Note: I'll need good detail, I'm close to Vegas retarded.
