Question RE: Plug-in Order
I’ve searched this without luck — I am applying a Computer RGB to Studio RGB effect to video that is also chroma-keyed.
Does the plug-in order matter? Should I apply the RGB color correction before keying the clip? That makes sense to me in one way, but I’m uncertain as to whether Vegas works with the underlying footage for the key, or with the evident color of the clip after the color-correction is done.
Thanks in advance for any help.

Yes i believe it does. If you use a plugin that changes the color before the key, use the eye dropper to select the color your keying out after the previous plugin is added. Vegas’s chromakey is not very good though. It has no spill supresion. If your using DV footage, try putting a chromablur, set to medium before the chromakey plugin and see the huge difference with the jaggies. Hope this helps. Danny Hays

I’m actually using HDV footage — I’ve tried the chroma-blur trick, but haven’t seen much difference in the jaggies. This is HD footage from a Canon HV20 — I’d assumed that I didn’t see much difference in the jaggies with chroma-blur because of the different color space?
Because of a prominent vertical element in the film (the back of a chair), I’ve had to up the blur on the key to around .1, which I think is a no-no, but I haven’t rendered anything out to look at on a TV yet — I’ll see if it’s bothersome. The project is a class presentation — mostly a single person talking, and the background is a still, so I’m hoping the blur won’t be that focal.
Thanks for your help.

oh, the chromablur only makes a difference with dv color space 4.1.1 as you said.
If your backlighting your subject to reduce spill, you can get a decent key with hdv.
For excelent keys look at keylight and ultra.
Good luck
