Transparent Background
In photoshop I can pick a color and make it transparent in the png file that photoshop generates.
I can drop a png onto a video track in Premiere. Premiere has a lot of video effects I can apply to that png, just at though it was a video clip.
Is there a way to use one of these video effects to make a color transparent like I can do in photoshop? BTW I don't really understand what most of the video effect do except for things like color curves and stuff like that. I thought one of the key effects would do what I want, but I can't seem to make it work. Key is something use when you take a picture with a green screen in the background, right? It's something I've never used.
I don't want to do it in photoshop because I want to save a step in my workflow.
Any pointers on how to make a color transparent would be appreciated.
TIA

Otherwise, if you want to drop a specific color to transparent, yes, I believe that would be a "key" related effect:

I believe that any pure color, or narrow range of colors, may be keyed, as can luminance.

Yes, I now see that keying is what I want to do. After poking at it a bit more I've got it working finally so that the backgrounds of the little png's I drop on a video track don't cover what's beind them, though I can't say I undersand the detail of how keying really works.
First of all there are a quite number of different keying effects available.... one is called "Ultra Key", that sounded good to me
It seems Adobe doc's tell where something is but rarely are clear about what it does. I often feel like the only kind of question I can ask the Adobe help is "Who's buried in Grant's tomb?"
Thanks Ziggy.

Luma keys are based on luminosity.
Chroma keys are based on color, and is how they put the weather man in front of the map using either a green or blue screen.
Matte keys use a grayscale image to describe the matte, just as in PS.

Anyway, garbage just means that they're quick and dirty, as far as I know. They're not going to replace meticulous rotoscoping, but they'll get you by sometimes. I would use them for my editing at work, but all the work I do is offline. Someone else would replace my garbage matte (along with every frame of the footage) on a much more expensive and capable system (both hardware and software). But for your needs, one man's garbage could be your gold!

yep! Quick and dirty. though I use that very thing for a vignette too, and along with opacity over an adjustment layer it works well~
What you're describing here is keying. And as David said, that is the norm for removing color in Video.
Supposedly premiere has a new keying ingredients. But I tried it on CS4 and found it lacking compared to AE. Also I think Mocha is supposed to be with premiere now too. I'm busy transferring a tape to digital otherwise I'd look to see if I have Mocha.
I don't have AE, but I've gone though a number of tutorials about it. At least for animation it has a lot fo the features that CS5.5 does, so maybe it keying is close too. I use simple animations in my videos a lot and I had thought about getting AE for that purpose, but wanted to avoid the learning curve. In the end I found I could do everything I wanted with Premiere 5.5's animation features.
BTW you know about Adobe's new upgrade policy, right? You won't be able to upgrade from CS4 to CS6 when it comes out.

Yeah, I do, I'm presently on CS 5.5 and I hear you on the curve. I hadn't tried it (keying in premiere) since CS4 but will look at it again. Thanks
