Hi Josh
1) create a lowrez in AE (ensure that its aspect ratio matches the high rez)
2) track the low rez with mocha
3) apply mocha tracked data to layer in AE (in low rez comp)
4) apply Scale Composition script - File>Scripts>Scale Composition.jsx
set width to actual high rez dimension.
5) place high rez backing/tracking plate into comp - switch off/delete low rez backing/tracking plate
6) replace (alt/option + drag over) insert layer (layer with mocha tracking data)
7) for mocha corner pin data, set the insert layer's Scale to 100%
8) for mocha transform data, place this Expression into the Scale property - value/3
The number 3 should denote the scale factor of the original rez relative to its low rez version. For example, if the original was 1920x1080 and your low rez is 640x360, then the Expression should be value/3
9) for mocha V3, exporting a 3D Cam Solve requires no manual adjustment as the Scale Composition script only affects AE's camera settings
