Does anyone actually use auto trace?
What do you use auto trace for (aside from super tight junk mattes). I have a lot of rotoscoping coming up on this next project.
example:
Camera is trucking down alley way. Girl walks into frame, says something to the camera and then continues to walk out of frame
I need to put a bunch of graphics and graffiti type stuff on the walls behind her. Usually I’d just go frame by frame and mask her out.Obviously this takes forever and is conducive to head aches and fits of rage. Additionally, I simply do not have time to creat such a detailed mask by hand.
I was thinking of employing auto-trace, but have never been to get very good results. I’ve never been able to create a mask that I could use for this sort of thing.
I know there has to be an easier way to do this. Maybe I’m not getting the most out of auto-trace, maybe there’s a different method completely that could help me out a little?
I’m open to all and any suggestions.
Thanks!

Sounds like a job for Mocha. Or Mocha AE. Silouette I hear is good, but I’ve never used it.
Either way that is a bit of work. How many seconds is it? You may be better off just starting to roto it.

Sorry to reply again,
I’ve used auto trace when Tracing the alpha of an object.
And when it comes to that project, if you haven’t started it yet, maybe you should green screen it….

I ahve two shots that last about 6 sec each. Re-shooting is nto an option. I thought Mocha was a motion tracking app?
I’ll look into it.

For all intents and purposes, mocha is a 2d tracker on steroids. It enables you to pull mattes, and do some sweet tracking and pinning. And for its price point? Its very worth it. It also enables per vertex feathering, which AE lacks unless you have a plugin.
Its no magic bullet though, roto work always takes quite a bit of time.

*Magic bullet as in solution, not as in software. Sorry.

Yeah, I’ve watched a few tutorials on Mocha. It seems pretty sweet. It’s on my purchase list for sure.
I don’t know if I’ll be able to snag it for this project though.
Might just have to pull a few long hours and roto the damn thing.
thanks for your input

Hmmm
Can you build a moving clean plate and pull a difference matte?
-
I’m not even sure how I would do that. I don’t think so.

My only experience is with autotracing layers that autotrace easily and accurately, mostly high contrast stuff.
Looking at your test image, I’d say an autotrace run would generate about 600 separate masks per frame. SWo You’d want to wrap a garbage matte around her first.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

Yes i have actually used auto trace, but like david said, for high contrast stuff.
is that the position of the camera through out the whole thing?
if it is why not take frames where she isnt in the spot where she was, then blend them together?
another thought, and i have no idea if it would work, could you do a reverse of time difference?
just throwing out ideas. 🙂
