Stop Motion but Moving Camera

Is it possible to maintain a smooth tracking motion while using stop motion?

What I want to do is use compositing to overlay stop-motion elements over a normal video.

What I want is very similar to this Dashboard Confessional video, except instead of the fast motion i want random elements appearing and disappearing.

Any thoughts or advice?

Much appreciated.
 
im just wondering how they even did the fast footage with him being in normal speed.
 
I think they shot a bunch of timelapse and then he is shot on greenscreen and superimposed. It may be a mix, but most of it looks like he is carefully matted in.
 
Yes, what you could do is this:

(1) track normal video plate

(2) import track data into 3d app

(3) create approximate geometery that represents the real world gemortry

(4) drop alpha mapped planes of People/objects that you want to "composit" and merely adjust the opacisty over time to simulate it appearing and disappreaing.
 
Thing here is a combination of alpha masks, CGI, and blue screening going on in that video... Each technique works for each shot. Obviously there is a lot of live action and TL mixed in as well.

I just had a detailed look again and it seems Arsons probably spot on.


Why do we guys always end up making simple effects harder than it has to be (or at least I did anyway) :cheesy:
 
I've been a 3d/cgi guy since 1989. I still try to do anything I can practical because it's just faster and more realistic. If you need hyper-real or something that would otherwise be too difficult, costly or dangerous to do, then go CGI. Although a lot of people doing independent project choose the CGI route because once you have a computer and the software then all you need it time and skills. But when you need some usable footage by the end of the day then going practical can speed things ip. IE sometimes hooking a scarf to a fan and shooting it on green screen is easier than animating the same scarf in maya and making it look realistic in the same amount of time. All cgi looks fake unless you spend the time to get the motion, modelling, texturing, and lighting perfect.
