[Andrew Kimery] “Could Adobe do the same thing Avid is doing? Yes, though I think it would be significantly more difficult for Adobe to pull it off because they offer so many more programs than what Avid is offering.”
I honestly think you guys are way overthinking this. 😉
As I pointed out in another thread, all Adobe has to do is apply the Acrobat DC model to the rest of their creative applications. Or they could do what Avid is doing, or maybe get creative and invent something new. Choice would not be rocket science *if* they wanted to offer it.

[Bill Davis] “My perception of Washington regulation is that they gleefully regulate right up until some party with massive clout doesn’t like the regulations – then they find a clever way to make the regulations moot. See all those CEOs and CFOs languishing in jail after nearly tanking the US economy in the 90s? Didn’t think so. “
Spot on, Bill.
Adobe is the one of the largest software companies in the world and CEO Shantanu Narayen sits on President Obama’s Management Advisory Board.
Does anyone honestly believe that if Adobe wanted to sell software, they would be allowed or couldn’t work out a loophole to make it possible?
If so, I have some awesome bridge front property I’d be happy to sell you , lol! 😉

[Dave LaRonde] “IF you can duplicate an animated mask, and IF you can reposition said mask, you would spend a lot of time getting one shot right the 3D effect. You’d then have a horizontal & vertical offset you could apply on subsequent shots… I think. I don’t know how the parallax would affect mask placement.”
It’s actually not an issue, the camera takes care of all of that for me. All I need to do is duplicate an animated mask and move it to a different part of the layer.
[Dave LaRonde] “That’s all I got. This is some crazy, cutting-edge stuff you have going, sir.”
It’s definitely on the bleeding edge, lol. Thanks anyway. 😉

[Dave LaRonde] “If you’ve proven that it works with moving people on test 360-degree footage, you should be set. No test yet? You should. You can use poorly-lit, crummy-looking footage just to prove the workflow.”
Oh we’ve done tests. And they work beautifully. I wish I could show you some screen grabs because it’s really cool and as far as I know, no one has done anything like it before. Hopefully soon.
[Dave LaRonde] “My concerns come when other people & things pass in front of the masked subject. It’s only inevitable that it will happen. I don’t know how big a deal that is in your case.”
It’s an issue and I’ve been dealing with it by hand rotoing the masks and being careful about layer order. It works. We have the attention of an in-house researcher who’s developed algorithmic methods of doing this based on her advanced computer vision research. It’s truly mind-bending stuff and I hope we’ll find a way to incorporate it into our workflow.
My problem isn’t creating a complex animated mask. I can do that just fine. My problem is I need two identical copies of the animated mask on different parts of the same layer – one for the left eye and one for the right.
Remember, my single layer is actually a over/under L/R stereoscopic pair with the left eye on top and the right eye on bottom. After I’ve perfected the animation of the left eye mask at the layer top, I don’t want to re-do all of that work for the right eye on the layer bottom. In fact, to avoid stereoscopic artifacts, it’s actually crucial that both masks be as identical as possible.
I simply need to duplicate the left eye mask with its path animation and move the copy to the lower part of the layer for the right eye. It should be simple. Duplicating a mask is easy, but the path keyframe animation references the absolute position on the layer. I need the duplicate mask to have a relative position offset so that it’s path animation stays the same relative to itself, but the mask’s position on the layer is anywhere I choose to put it.
Make sense? Any advice?

[Dave LaRonde] “I guess this person you’ll shoot is in some sort of environment that precludes chroma keying.”
This is exactly right. Imagine a live, outdoor event with many people throughout the day. The camera is a 360 degree stereoscopic camera:
https://www.google.com/get/cardboard/jump/
I don’t need to replace the background so I don’t need the precision of chromakey. I do need to isolate moving subjects and masking works well.
[Dave LaRonde] “Or maybe I should just stay out the discussion. I don’t think I’m getting your intent.”
Let me try to be more clear because I’d appreciate your insight.
Let’s say I have a path keyframe animated mask. I want to duplicate that mask and move the copy to a different part of the layer, while keeping all the animated movement.
Is there a better way to do this than using the KeyTweak workaround I’ve described?

[Dave LaRonde] “I guess I wouldn’t even bother with masking. I’d try chroma keying if those two cow graphics are on colored backgrounds. I bet you’d get a great key.”
lol, I’d love to be able to chromakey but that won’t be possible for the kind of video I’m working with.
In case it’s not clear, my samples above are just placeholders to illustrate the problem. The cow represents a person who’s outside in a public location. The difference between start and finish is the person moving in live video. Hence the need for masking.

[Roland R. Kahlenberg] “Have you tried Effects>Distort>Transform ?”
I don’t think that will work because it transforms the layer. I only want to offset the mask. Am I missing something?

[Walter Soyka] “Out of curiosity, what is the last 10% of the challenge that you can’t cover in Premiere? Maybe someone here would have a suggestion, or maybe there’s a good area for a feature request.”

[Tim Wilson] “Timmy likes!!!!”
Excellent! Will keep you posted as we get further along. It’s still early and we’re still figuring things out. Fingers crossed…
[Tim Wilson] “Stupdendous thread, as some of the COW’s big throbbing brains stride across the land like the giants they are.”
Keep your eye on the After Effect forum because Walter S. and I are going in deep. Here’s another thread that might interest anyone who uses Dynamic Link between Premiere and After Effects and has ever wondered WTF happened to my dissolves?
https://forums.creativecow.net/readpost/2/1067127
Walter’s dropping hardcore science and I for one am learning a ton. It’s the COW at it’s best and why I enjoy this place so much. Stand by for more…

[David Cherniack] “That said, when I re-build my Premiere editing station it will be on dual xeons.”
David – Is the reason you plan on choosing dual Xeon in the future because you want dual processors or more RAM than you can get with i7?
