Hello all, as we know, to integrate CG elements into live action footage, the footage must be camera tracked where a 3D camera will then be obtained and work can proceed further in the 3D program and then composited in AE.
As you may know, a Prime Lens is one with a fixed focal length, e.g. 35mm or 85mm and it cannot zoom because it is not a zoom lens. You may also know that an anamorphic lens squeezes the image onto the sensor to create a wide image and it is desqueezed for post-production work.
The question here is:
Looking at all the processes involved in the matchmoving/camera tracking workflow, would it be faster tracking/matchmoving a plate that was shot with a prime lens? Therefore would the process take longer if the lens used was an anamorphic lens?
I ask because I read that there is a desqueeze and resqueeze that needs to be done before and after the CG work is done, therefore I thought working with plates shot with a prime lens (fixed focal length) will be faster than an anamorphic lens workflow.
I would be grateful for your input.
Doesn't matter. The math is the same. Even anamorphic lenses are spherical lenses and whether you correct the PAR of the footage first or dial in some values in the solver is secondary. The only real difference is that for variable zoom stuff the camera solver has to run multiple times or even at every frame to figure out a consistent filmback size and all that stuff.
Thanks for your input Mylenium; appreciated!
