I've been asked to do a job with 4k footage (4096x2160) which has some kids standing and holding up a sheet of standard white poster board, and the client would like the logos of different organizations tracked and inserted onto the poster boards.
The 4k footage is a different aspect ratio from the poster boards and all of these organization's logos are different sizes and different aspect ratios. The tracking is easy enough in Mocha AE and I can precomp logos and apply the tracking data to the precomps, however, because of the differences between the aspect ratios of the logos and the aspect ratio of the poster board the logos don't keep their correct aspect ratio even after doing a fit to comp. I've had to manually tweak the scaling and judging by eyeball until the aspect ratio of the logo looks correct on the footage.
Just curious if there is an easier and more correct way to accomplish this. I've watched a couple of tutorials and they mainly deal with instances in which your footage aspect is different from your insert layer which is in the same aspect as the surface, such as a phone screen. Manual corner pin and align to surface in Mocha AE also don't seem to address the issue as the aspect ratio of the logos are different from the poster boards...or I'm not understanding how to do it correctly.
