I created .gif file with 360 frames from a rotating tower in blender, every frame is 1 degree of rotation. However, there is a bit of curvature on the left and right end of frames. I want to make them all completely rectangular, but I don't feel like editing all 360 frames.
What would be the best way to modify all the frames at the same time, because the curving on the edges is the same for every frame?
