Using Mocha AE plugin v6.1.3 on an old, black and white shot of a building I-beam being raised on cables (don’t ask). After a lot of work, think I got a reasonably solid track based on the purple grid. But now comes the problem.
I need to attach a logo to the bottom of the beam. However, none of my Google searches have turned up how to attach a shape via cornerpin when you don’t have reference points. I used the corners of the beam to adjust the track, but that makes the logo match the size/shape of the beam (there’s also the issue of the edge angles twisting as the beam moves but one problem at a time). I tried just using Transform data which isn’t awful but clearly isn’t right due to the Y-axis swing of the beam. I can’t find how to correctly set Surface corners that won’t distort the logo without reference corners in the footage.
I can’t show the footage but here’s a quick trace of what the final result should be and where I believe the Surface corners should be. I’m not a Mocha whiz by any stretch so maybe I’m overlooking something very fundamental.
