You guys know those roto masks that you see a ton of folks use that are part black and white? I figured out how to do this using Gimp but the masks that I made... "image stream" are only part black and the rest of the image is just plain transparent without being white. Plus I had to use 2 to 3 layers with an invert selection, one way on the first layer... reversed on the 2nd layer and I forget what I did to the 3rd layer.
I wrote down the process on a note pad but I think I left it in my friends car a few weeks ago but I'll try to get it tomorrow. So I was wondering if anyone knows how to do this without having to use so many layers. And yes I know that I could just use the masks and garbage mattes in Visionlab but they can't do a whole lot when it comes to dealing with individual hair follicles which is the only reason I tried to do this. It does work though.
So if you know of a way... can you please let me know? And if not I'll post a tut on how I did it using Gimp as soon as I get my note pad back.
Thanks in advance.
I just figured out how to do this in a way that will work with Grade objects, like if you wanted to change someones hair color but not for keying purposes. If I figure that one out I'll let you guys know.
Okay sorry about that. It's been 2 minutes and I figured it out. I can get it to work for stuff like when you don't have a greenscreen and you want to change the background in a scene. Of course it's better to have a greenscreen but if not, then this little bit of info might be able to help someone. I'll post a tut very soon but I have to crash right now. It's kinda late.
