TimeRewind synthesizes the video backward into the pre-capture time with image-and-events video diffusion.
TimeRewind synthesizes the video backward into the pre-capture time with image-and-events video diffusion.
Comparison with Standard SVD and baselines, E2VID+* [48], EVDI* [59], and REFID* [48].
Below are backward-time videos synthesized from the reference video's last frame and events.
Sequence 1:Sequence 2:
The motion in before-the-capture time mostly comes from a few rigid body objects.
Note that since our task is backward-time video synthesis, the motion in the video is the reverse of original.

Sequence 4:
The motion in before-the-capture time is either due to animals and humans performing actions or scenarios with both the camera and the objects moving.
Note that since our task is backward-time video synthesis, the motion in the video is the reverse of original.

The motion in before-the-capture time is either due to a dynamic fluid (water stream, fire) or complex particle motion under force .
