New to Mocha and relatively new to After Effects.
I have a 5 min long 4K clip filmed from an helicopter approaching and flying over a city. My client wants me to animate the route of a tunnel that is being drilled under the city. The route is relatively straight but there are 7 points along the route where there is a smaller bend or vertical ventilation shafts. The animation will only be a wide line/stroke and I would like it to be in perspective (wider closer to the camera and narrow close to the horizon).
(In short: I need to create 7 null objects (“3D”/XYZ) along the route, which are in the same coordinate system and they have to exist during the entire clip.)
I started with Camera Tracking in AE, created null objects at 3 of the 7 points and connected the nulls with ConnecLayersPRO. It’s been working great and just as I want it, see attached screen shot (ignore the green plate). However, the Camera Tracking does not want to track more than roughly 1:45 min out of 5. It takes forever and always ends up in nothing. If the Camera Tracking would work for the entire clip I would be happy and the project finished.
I’ve tried to split clip in shorter sections, but the problem is that the 3-4 of the 7 points are visible during the entire flight so I can’t see a way to split the clip. Also, the nulls that I’m connecting with the lines/strokes need to be in sort of the same coordinate system in order for them to appear in perspective (“3D”).
Is it possible to track a 5 min 4K clip in Mocha?
What would be the best workflow for this?
I would need “XYZ-nulls” from 7 positions along the route.
I would be super grateful for any advice pushing me in the right direction!
