There is a Cool3d Prod. file that I wanted to experiment with in Video Vegas that was posted in a different forum It's a "Video Overlay". I don't know what is meant by video overlay. I'm new to Cool3d but I've been using Vegas for a while, still hazy on how to do compositing however. The instructions to use the file pertain to using it in Ulead MSP. I was wondering if someone could translate this into how one would use this in Vegas 4. Below is the excerpt:

This is an overlay file for transitioning between 2 clips.

The overlay would be placed so that it overlapped with the

last 3 seconds of the first clip, then 6 seconds later the

2nd clip should be placed on the timeline.

It uses a freeware font which I included in the ZIP.

I used sample AVIs from Media Studo 3.5 to create the render example. I used Cool 3D Production Studio to export an overlay file, then placed both clips in Va (6 seconds apart), put the overlay in V1, and set it to Alpha Channel overlay. If you like it, feel free to use it, and vote for it.

A Video Overlay in C3DPS is just a video with an alpha channel. C3DPS prefers to create uncompressed avi video for this, although other formats also support 32-bit alpha channels. DV video doesn't support an alpha channel so you can't use a DV codec to create a Video Overlay.

An alpha channel makes "empty" areas of your video frame transparent. So if you typed a big letter "C" into a C3DPS project and exported it as a video overlay lasting for 3 seconds, everything except the letter C itself in that 3-second video would be transparent. If you put a video of your dog in the lowest numbered video track in Vegas (V1? I don't use Vegas but most video editing programs work similarly) and then took that 3-second video clip and put it into Vegas in track V2 (or higher), the end result would be a video of your dog with the letter C superimposed on the video for 3 seconds.

HTH,
