The Retimer tool lets you generate output footage at a frame rate that is different from that of the input by retiming the image. Two interpolation modes are available to perform the retiming: the Warp interpolation mode, which uses motion estimation to generate intermediate frames, and the Blend interpolation mode, which generates a weighted average of adjacent frames. The Warp mode provides significantly better quality.
Additionally, motion blur (temporal anti-aliasing) can be added so that moving objects appear blurred, as they would when filmed with a real camera, which has a finite shutter speed. You can then modify the timing and/or speed curves through the Animation editor in the UI to create a constant or non-constant time warp.
