I have a simple moving background playing behind several pictures playing in a row. Is there a way to have just the pictures transition while the video keeps on playing?
Here is how I have the show set up:
Va: Is the moving video background
V1: Is where all of the pictures are
V2: Is where the names of the people are
Any help in a short amount of time would be greatly appreciated!

I'm not sure if I understand you correctly... you want to transition between pictures, but cannot do that because they're on an overlay track? One option might be to move the pictures up into Va and Vb, and move the background into V1... or maybe setting key frame transparencies between pictures in V1, creating that 'cross fading' transition-ish effect. I'm not sure if those would work, or if I know exactly what you're talking about, so let me know! Maybe take a screen shot of your video project so that we could see it on here?

If you want to apply a transition between overlay tracks then no, you cannot do that in MSPro yet. Many have suggested it for the next build, but as of now this requires a bit of trickery.
Method 1:
This alternative, suggested by ejskater16 in an earlier reply, works and lets you use the overlay options transparancy control to simulate a crossfade between two overlay's using keyframes.
You'll need three keyframes per clip: the usual start and end keyframes plus one about .5 to 1 second before the end of the first clip and after the start of the second clip .
The fades are done by first overlapping the clips the same time interval while ramping the transparancy from 0 to 100 between the end keys of the first clip and from 100 to 0 between the first keys of the second clip.
Example pix:
Timeline
Soccerball overlay
Earth overlay

Method 2:
In this method you create a second project with the contents of the main projects overlay tracks (only two layers at a time now..) inserted to Va and Vb. Next apply the transitions you want and then render this project as a 32 bit uncompressed *.avi,. This results in a video file that has an alpha channel (transparant layer) that can be keyed out (digitally erased).
This file can then be placed in an overlay track in the main project where you can use the overlay options to apply an alpha channel, erasing the overlays background. from here you can apply filters, moving paths or whatever you need.
Method 3:
Altenatively you could render this secondary project with a black or white background using compression to make it smaller (DV, MJPeg...whatever). This file could then be loaded into an overlay track in the main project and the overlay options set to use a lumakey. This too will erase the overlays background, but IMO not as nicely as using Method 2.
While Method 2 is the highest quality of these techniques be aware that 32 bit *.avi's are uncompressed and VERY large, so the NTFS filesystem (Win2K, XP) is essential for sequences of any length at all.

Just to clarify for me...
In your example, are you hoping to have the blue background video visible as a frame throughout the video, while the image(s) in the center transition using the Va/Vb tracks?
If so, there is a very simple approach....
Hope this helps.

- - In your favorite image editing program (or CGInginity or VideoPaint) create an image file that is all black, with a white rectangle in the center that will be the size of the images in your finished video.
- In your video editor project, start by placing your "background" video on track V1. (yes, over top of Va/Vb).
- Open the overlay options for this V1 track, select Image Matte and use the image you created in the first step as the mask. Also set the overlay Type to be Gray Key. Click OK.
Hope this helps.
