Keyed out “white” background not white after export.
Hi… I tried searching for an answer, and saw that someone had a similar problem, but the solution they had doesn’t work for me. Here’s my dilemma:
I’ve got green screen footage that I’ve keyed out in Vegas Movie Studio Platinum 6 (I use 9 Pro at work, but this is a home-based side project) so that the background is white and everything looks more-or-less okay within Vegas. The goal is to have a short video sit on the homepage of a website with a white background, so I want the video to have a white background so it blends in and sits seamlessly on the page with no borders around the player.
The problem is, for the life of me (and I’ve been at this for days now) I can’t render anything that keeps the background white. With everything I’ve done the background’s colour shifts and is no longer white (usually pinkish). I’ve looked up countless forums, tutorials, etc., but nothing is working. It seems the best way (from other suggestions) is to render an uncompressed .avi and check off the “Render alpha channel” and “Create OpenDML” boxes–I’ve done this and it doesn’t look white. I’ve rendered in .mpg, .wmv. The only thing that seems to render white out of Vegas is a .mov file, but then I need to get the huge file small enough for the web. So I’ve tried using Handbrake and Flash Video Encoder CS3 to output a FLV or mp4… needless to say, they all end up with a pinkish background and don’t retain the pure white as seen in Vegas.
I’m running up against a deadline and am at a loss. Any help greatly appreciated!

It sounds like your Chroma Key is not fully adjusted?
Those MIN and MAX settings have to be tweaked “just so”, and sometimes there is only one teeny-tiny perfect setting for them. Not tweaked just right, they will cast a transparent glow on your layers below…
You’re not using White as your “keyed-out” color, are you? That’s a pretty difficult RGB setting to use, I’d say.

Why not shoot it in white to begin with and avoid all those problems.
D. Eric Franks has an excellent tutorial called Lighting Infinite White that helps explain this technique. -
They key looks good in Vegas. Very white, exactly as I’d like it to be. It’s in the export that things go badly. The only one that gives me something I’m happy with is .mov render from Vegas. But the resulting file is over a gig. So to bring it down to size I’ve used both Handbrake and Flash Encoder, but both produce bad results. I’d understand having general quality diminished after running it through one of these programs, but the colour shifts are driving me nuts. Other people have obviously been able to do this, since you see this type of video on plenty of websites.
As for shooting it on white, well, it’s too late unfortunately for that. The footage was shot with green screen and now I need to work with that material I’ve been given.
