Hi guys,
this topic has come up before but I can´t find
the corresponding threats so please excuse the
repetition.
I have a stitched backroundplate, 5:4 aspectration,
roughly 12500x10000px to which I have aligned
an XSI camera (~90%there due to the stitching).
Using lensshift.
Now I´d like to "zoom" the camera offcenter onto
a square area to get additional headroom for the
rendering, e.g. being able to render that region
in something like 8K without having to create
a ~25000x20000px framebuffer using the
Passes>Crop (to selection) option.
I remember a tool or script that would let you
"zoom" in or out off a plate, giving you the
corresponding focallengths, I think it´s main
purpose was to get overscan area for motion blur
calculations, I guess that´s what I could use.
Anyone got more info or tips on this?
Cheers
tim
P.S: Basically, I´m trying to use "PixelZoom" of Rotoscopy
in a fullblown render to get a higher resolution render with
identical perspective distortion while "cropping" away the
now useless area of the framebuffer.
