Hi all. I am a newbie here, and have a quick question.

I am using Sony Vegas Pro 8.0b Build 217. My problem is the following:

When I apply a velocity envelope to a clip and change its speed to anything but 100%, that clip will not render in the final video. I have tried rendering my video in various formats, e.g. mp4, avi, mpg, and so on; however, none of these will render the clips with velocity envelopes in my project.

How can I fix this problem? If I need to provide any other information, please tell me.

Thank you in advance, and I appreciate your taking the time to help out a new guy.
