I have found this problem a few times when using Sony Vegas Pro 10 and thought I would share how to fix the issue. The problem seen is when you render a completed project the video is black apart from your overlayed text. Yet if you click the play button to preview your project in Sony Vegas it plays your video clips ok. Not sure if this problem has been fixed in Sony Vegas Pro 11 (PC)
How to fix the black video render problem
Here is a screen grab of me fixing the problem. This is Sony Vegas Pro version 10.0c 64bit running on Windows 7. I have right clicked on the video clip and from the popup menu I have selected Switches then gone across to the sub menu and ticked "Disable Resample". This will fix the blank render issue.

Tip
If there are lots of video clips to disable then simply click the first one then hold the shift key down and click on the last clip on the same track and this will select all of the video clips. You can then right-click one any and select "Disable Resample" to perform this action on all video clips in one go.
Sony Vegas is now on version 11
I have discovered that this blank screen problem only seems to happen when you alter the frame rate of a video clip. For example if you have imported a clip which is 10 seconds long recorded at 25fps and you then hold the control key down while moving the right hand handle of the clip to the left, thus increasing the playback speed of the clip.
Its very annoying as it only shows on the render and not in the preview player window.
If you found my fix of use please comment.
Thanks
