Hii I have a question about tracking.
Im tracking a board (cutting matt) that lays on a table.
The footage is 4k.
One corners of the board is hidden along all the movie but the board has measuring lines on it so I can track a smaller area on the board without distructions and the tracking results are pretty good.
But then when I use this tracking, the "target" comp has to be the same dimensions as the tracked area, otherwise it will stretch the target comp to fit the tracking area.
is there a way to track the smaller but clean area and to put a larger comp so it fits all the board?
Mocha works well for this--it was built to handle that kind of thing. You could also use the 3D Camera Tracker, if there's enough camera movement--given the nice visible grid, AE should have no trouble tracking the table.
