2D Track /w clean plate or paint

[Seriphu]

Hey guys,
I have a nightmarish shot that I am having a lot of problems with. I am working in Shake for this project. Here is the problem, while shooting someone forgot to take off the tracking markers on a television screen from a previous shot that they wanted something on the tv. There is an insane amount of action and motion blur in front of the television which makes it impossible to hold a track on the TV long enough to maintain a 4 point track. We have the elements roto'd out nicely so I already attempted to take a still from the footage where the screen was 100% in view and painted it clean in photoshop. There is a sample pic of the shot to give an idea of how much the tv screen gets blocked.

If anyone could give me any advice I would be very grateful.

What's the camera move like? Is it super shaky? You could try to hand track it. Or maybe use a planar tracker like mocha and then export the tracking data in to shake.

Sorry about that, I knew I forgot something. Its a push pull, the fg goes from blurred to crisp and there is a slight dolly back. Im currently trying to hand key a move2D since the camera is stationary for the first 20 frames and the last 60.

I finally figured it out. For those interested I found a tracking tool that I had never touched before called track offset. If you are not familiar with it here is what it does.

This is in shake, im not sure how you would do it in nuke yet.

When you start a track at some point and want it to continue on without having to guess what point it was on you go to the last frame the tracker was locked to. There is a button in the tracker menu under the viewer that looks like a box with an X in it. When you click it you can move the tracker to a new location that you feel is a nice point to track and continue on. Even though the tracker is in a new location the data is transfered to trackers point of origin. After that it was just tweaking in the curve editor.

Nice, glad you got it worked out.

yea this tool is definitly a godsend

when you are trying to track something that goes out of site or anything like that

the problem comes from trying to track on a different plane then you get a bit screwed

Is the same tool available in nuke? I have not had a 2d track in nuke complex enough to need that yet.
