keying out without Chroma Keyer
I’m creating and editing a commercial in Vegas Video 7. I want to cut people out of old footage to use in this composite. I know I could chroma key a subject out if it was shot in front of a solid color but is there an easy automated way to key out a moving subject in regular video. I know I can key fame a mask, and possibly feather it, but that will take a long time to get right and I only have a couple of days to do this commercial.
PS
I have access to After Effects but I’ve only used it a little and it seemed like most things people use it for require the purchase of extra plug-ins, which I wouldn’t have..Thanks for any help you can give.

You can Rottoscope with After Effects, but that is like keyframing a mask in Vegas, very time comsuming. There is luma keying, which I believe can key out very bright or dark backgrounds, but other than that, your stuck with a time consuming job as far as I know. Unless someone else has an idea on how to do this easier. Danny Hays

Thanks Danny
This is one of those rare times I feel like a spoiled American consumer. Not that I could tell you how to create an automated, motion tracking object keyer but I would think someone would have.
Of course I’d want it for free and would complain if it had limitations.
So I’ll go back to being appreciative of the high quality, low cost tools we all have these days and get to work on this rotoscope work.
Thanks again.

Richard,
sometimes it is possible to key out a subject from the background using the secondary color corrector without having the green screen. However, whether it will work in your case really depends on the footage.
Here is an example:

Someone has! Take a look a After Effects CS5. It has an an automated rotoscope tool for exactly the problem you are trying to solve. I just got my copy and am installing it today so I’ll see how well it works but the demo is amazing. Look at this demo and prepare to be amazed:

The guy in the video has some good contrast on the edges so I’m not so sure how well it will pick someone out of a crowd of people but it sure is impressive technology.~jr

Wow, Cool John. I didn’t know if there was a tool yet for this. I’m also playing with CS5 but hadn’t seen this yet. Thanks, Danny

Wow!
It’s like those Windows7 commercials.
“CS5 was my ideal”Only wish I had the cash to do some major ingrading to 64bit 🙁
It won’t work on my archaic 32bit XP professional machines.Every machine is dual or quad core. I just never switched to a 64bit OS. So much for not liking change.
Boy I’m getting old.Thanks for your input.
