It is 2D vector field where each vector is a displacement vector showing the movement of points from first frame to second. Consider the image below (Image Courtesy: Wikipedia article on Optical Flow ).
WebJan 24, 2024 · Jan 24, 2024. When altering the speed of a clip to slow it down by any percentage and selecting either Optical Flow or Frame Blending as the method of Time Interpolation, the result still simply displays/renders as though Frame Sampling had been selected (jittery with duped frames). Even after I render the clip, I can confirm this is the … WebApr 12, 2024 · It is a remarkable change of direction, but those magic extra frames aren’t conjured from thin air. DLSS 3 takes four inputs – two sequential in-game frames, an optical flow field and engine data such as motion vectors and depth buffers – to create and insert synthesised frames between working frames.
