The Foundry Camera Tracker versus Imagineer Mocha Ae v3 Camera Solver Feature

[Ian Douglas]

I think Ross explained very clearly why I own both AE Cs6 (now but not when I originally posted) and the upgrade to Mocha V3.

As far as the ‘alternative’ or specialized 3D camera trackers these are not free and some of us are just amateurs and just cannot justify the extra expense (in my case).

I think todays contributions to the thread, by all, have been really useful and enlightening.

Thanks

Wow Ross, your explanation was very good!

If I’ve correctly Understand, we have to use specific 3d tacking sw when we have to rebuilt an entire geometry scene in a shoot with deep focus and many objects (people. f.i.) or geometries (Buildings, houses. mountains… f.i.). In a shot with soft focus, just with an object (in focus) and a defocus Background, you are not interest ti build a 3D Environment but just to place moving plans in synchronism with the original camera movement.
If have I understand…

Hi Simon,
I think you’ve got it. I would not get overly hung up on the “focus/depth of field” aspect of my explanation.

Think of this as an example: say you used mocha’s 3D solver to solve the position of an actor on a set and the track looked spot on and a 3D Null represented the actors position in relation to the camera. If you viewed this 3D camera and Null from a top view in After Effects and repositioned the Null in Z space, it might not necessarily be in the proper 3D space. So yes, for multiple 3D objects interacting in a scene, mocha’s tracker is not the appropriate solution.

mocha uses only couple planes in its 3D camera solver. The more you use, the more accurate the solve will be, but still – it is using a different method than camera tracking software.

Best,
Ross

Good Ross, very clear!
Many thanks!
