I'm hoping to be able to render frames of an animation where I render slices that are set to different points in the animation. This effect could easily be achieved in after effects but the render time in Blender would be drastically more so ideally I'd like to cut it down. (Have lots of slices and cameras to merge into single images)
Is there a way to have the animation at frame 1 render the top 50% (or any number of pixels) then move the animate to frame 50 and complete the bottom 50% of image. This would become frame 1 of the rendered footage.
Same then start the next frame this time with frame 2 in the top 50% and frame 51 in the bottom 50%. And so on until we have the completed animation with bottom half offset by 50 frames.
Any advice would be appreciated so much.
