Problem:
keyframes from camera tx, ty, tz, rx, ry, rz ranging from 1001 to 1195
need to have their timing remapped, such that the new timing is sped up by 2x
thus, the formula where kT = original frame, is ((kT - 1001) * 0.5) + 1001
This will give us new keyframes from frames 1001 - 1098.

New frame range after re-speed is 1001 - 1093, we just truncate frames 1094 - 1098.
