What is motion blur?
Definition
Motion blur is the streaking of anything that moves quickly across a frame, as a camera with an open shutter would record it.
Computer-generated movement has none by default: each frame is perfectly sharp, which can make fast moves look like a series of jumps. Adding motion blur to a zoom or a camera move makes it read as one smooth motion.
It is produced by rendering the scene at several moments within the frame’s time and averaging them.
In Sceed
Sceed can add motion blur to zoom moves, sampled along the camera’s real path, at any strength.
