you track up to the part where the track dot is obscured and then you need to go to where it appears again and start tracking again. We do many previews to make sure that the hand tracking we do inbetween cover ups look as realistic as possible. Many times we dont do four corner pin track, insead we track each one by itself and use expressions to tie the tracks back into our cornerpinned image. this allows us to focus on getting each track nailed down one at a time, and works pretty good. Hopefully you know how to do that. We dont have very good luck with tracking when the dots are cut off at all, you really have to spend time getting the tracker to look realistic when you have footage shot the way that you do. We now try using Boujou or some other product to track random dots in the entire scene and then place a box in 3d space where the TV is so that the track looks better. Any way you slice it there is much more work this way. You can try to find other objects that are on the same plane of existance that are not blocked and then offset the track center, but once again this has no guarantees. Good luck.

What we do here is render millions of colors RGB+alpha channel which can be set in the render Queue. When you import that file into FCP it should retain the alpha channel. If that does not work, you can render the alpha channel seperately in the Queue, just pull down to alpha only. That should render only a B/W QT. This can be imported into FCP and used as a luma matte. if I remember correctly, you place the B/W movie under the color version of the movie. Right click the top color movie go to composite mode and travel matte luma. You would be way better off if you can just embed the alpha with the QT. One way you can check to see if there is an alpha channel is to re-import your render into ae, and then check if the alpha channel is there.

Could it be that the small parts of the circle are crossing over two different fields?
I have had that cause dancing. If the dots are vector based, try turning on continuous raster. -
Are you shooting a foreground plate and a background plate?
if so you could posterize the foreground plate to make trailing copies.
then you could distort the trails using caustic maps or ripple or whatever you want to taste to mess up the image. Then you could transfer mode and change the opacity to achieve the desired distortion. -
Hi,
NTSC is 720×486. This should be fine unless you are working in the 16×9 aspect ratio, then you should work in the 864×486 and then stretch in the render cue to 720×486 stretch. For fields we usually use lower fields in our shop, but this is totally dependent on what system you are laying off too. Hope that helps
