i downloaded the free set (Studio5) and cant figure out how to composit in VV.

their support said

"Depending on which set you downloaded you will have a background, a background with alpha for the screen, and a foreground with the desk.
The background you put behind your keyed talent.
The background with alpha for the screen you put behind your keyed talent then put your video into the screen behind the background.
The foreground you put in front of your talent to make it seem like they are behind the desk."

OK, so i can figure out everything but how to composite the foreground.

Also cant figure out how to-then- composite the video screen below the other tracks

Here are the directions for Digital Juice, which should be similar:

1. Set up tracks as follows:

Track 1: Overlay matte (multiply mask)
Track 2: Video stock (child)
Track 3: Background

2. Click Track FX button on track 1 and select Mask Generator tool.

3. In the Mask Generator dialog select a Luminance key from the Type dropdown. May need to click Invert checkbox to get desired effect.

4. Click the Compositing Mode button in Track 1 and select "Multiply (Mask)" from menu.

5. Click the Make Compositing Child button in Track 2.

thanks

that doesnt seem to be working well + it doesnt adress the video screen below (in other words, multiple layers of composites.)

I downloaded the set. Here is what you do:

Step 1. Add 4 tracks to your Vegas project. From top to bottom they will be numbered 1, 2, 3, 4 with 1 being the highest and 4 being the lowest.

Step 2. Place the image that you want to display in the small monitor/screen on the bottom track (Track #4)

Step 3. Place the file “Studio05_SD_NTSC_BG_0001.tga” on Track #3.

Step 4. Right click on the event for Studio05_SD_NTSC_BG_0001.tga and select Properties > Media tab. Then set the Alpha Channel to Straight (unmated). You should now see the bottom track show through the background where the monitor is cut out.

Step 5. Place your talent on Track #2. They should be chromakeyed doing whatever chromakey magic you usually do because you only want the talent on this track (with no background)

Step 6. Place the file “Studio05_SD_NTSC_FG_0001.tga” on the top track (Track #1)

Step 7. Right click on the event for Studio05_SD_NTSC_FG_0001.tga and select Properties > Media tab. Then set the Alpha Channel to Straight (unmated). You should now see the background disappear leaving only the desk in the foreground in front of your talent.

Your track layout should look like:

Track #1: Studio05_SD_NTSC_FG_0001.tga
Track #2: Talent
Track #3: Studio05_SD_NTSC_BG_0001.tga
Track #4: Monitor video

Hope this helps,

Thanks much...the Straight (unmatted) is what I was missing

Great! I almost forgot. If you click the little floppy disc icon next to Stream properties after you set the Alpha Channel to Straight (unmated), Vegas will save this setting for all TGA files. This way you don’t have to right-click the properties every time you drop a TGA on the timeline.

I like the demo set you chose. I have been trying to figure out a way to get talent
shadow on walls. The only way I have found was to use the chromakey mask
as a transparent "gobo" using a 3D program such as Truespace to shine
a virtual light through this gobo onto a wall. That wall is used back in vegas as an
alpha. The same background but lowered brightness keys through.

This is so tedious. Has anyone used the 3D in Vegas to do this?

EDIT: the reason why you can't always offset down and to the side the chromakey mask
is because the wall may not be flat. It would look like a cardboard shadow in front
of the set wall. Virtualsetworks does a great job trying to keep shadows away
from walls or other surfaces.
