I am having the exact same issue (windows 7 64bit, master collection CS4). My computer is a serious powerhouse so I know it’s not a performance problem. I even tried on a second computer running the same software and it failed there as well. I’ve looked everywhere for a solution and turned up nothing but dead ends (adobe is no help). Sorry I can’t offer any advice.

[RuneMadsen] “I want to be able to move the camera (pan, tilt and dolly) and still be able to put footage in the green screen area in the right perspective…”
This really depends on what your backgrounds will be like. It depends on what’s in the shot, what lens you’re using, how much movement, the size of your subjects in the frame, the distance of your subjects from the background, and how “real” you want it to look. Your technique is capable of tracking only two dimensions, but the perspective within the shot is affected by 3 dimensions. For small movements it should look almost perfect, but say, for a long dolly shot the perspective will skew unless you shoot the backgrounds with the same dolly movement.
I’ve done this before with my foreground subject being quite large in the frame and it came out great. Depending on what you’re doing your results will vary. Let us know how it turns out.

Okay, It’s time for a new problem now. You guys really helped me out on this. I set my comps to 24fps and I added 3:2 pulldown back in. The beta footage looks great under those settings. The new problem, however, is that the footage I’m compositing over the beta footage originated on HDV and was shot at 29.97fps. So now, when I render the compositions with 3:2 pulldown added in it makes my composited characters move all crazy-like on top of flawlessly moving backgrounds. Is there anything I can do for this problem? I’ve been working on this project since last october and I just wanna be done! Thanks in advance.

thanks, I’ll give it a go.

I can’t find the menu option to add pulldown anywhere in my render settings. I’m using AE 6.0 . Where might I find it?

Way better color quality with the beta. Maybe I am misunderstanding something here. I intentionally set all of my compositions for 29.97 fps. Isn’t that what I should do? I remove the pulldown to treat it as 24fps but I thought that if I set the actual composition for 24 fps it would cause problems when I render because I am editing in a 29.97 sequence in AVID. Does that make sense? Could this be the problem? I could try setting my compositions to 24 fps but how do I then reintroduce the 3:2 pulldown so I can use it in AVID?

The footage on the DVCAM and the BETA is identical. But I had no problems with the DVCAM. There are many many shots on these tapes but I have interpreted them each individually. The problem is that there is no existing phase which does not cause repeated frames. The other thing is that AE recognizes the pulldown and specifies a phase, but frames still repeat with the beta footage. I can’t wrap my brain around this. I’m totally frustrated.

It’s obvious to me that you’ve already shot this and it’s too late to re-light. And since you’re using DV I must highly highly suggest trying DVmatte Pro by DV Garage. It’s just a plugin and it works freakin’ wonders. It’s made for exactly your problem. I used it recently to do the same thing and it saved my life. I don’t know how much it costs as a standalone, I got it with a package. But I’ll bet it’s pretty cheap. I had actors moving too quickly and I couldn’t key out the green but not the blur. DVmatte Pro kind of works by interpolating blur and removing the green on a gradient so you get nicer edges and get to keep your motion blur.

The problem I ran into when doing this earlier in the week was that after removing pulldown many clips were strobing. I have discovered that several clips were incorrectly phased in AE wheich was causing this problem. I solved the problem last night by having AE determine the phase for all 200 or so clips individually by going through them one by one and telling AE to guess the phase. (Last time I had applied the interpretation to all the clips overlooking the fact that the phase would not be guessed for all of them but rather set to whatever the first one was.) This had been the mistake. I linked these clips to my existing 29.97fps DVCAM composites and rendered them at 29.97fps. About 20 minutes ago my render from last night finished and all 50 composites are perfect. The blocky edges are gone and the motion is flawless.
