FlowC2S: Flowing from Current to Succeeding Frames for Fast and Memory-Efficient Video Continuation

Christian Sandor, Hovhannes Margaryan, Quentin Bammey

FlowC2S flows directly from current video frames to succeeding ones, halving input size and outperforming prior methods with five evaluations.

Claims

C1strongest claim

By flowing directly from current to succeeding frames, instead of the common combination of current frames with noise to generate a video continuation, we reduce the dimensionality of the model input by a factor of two. The proposed method, fine-tuned from LTXV and Wan, surpasses the state-of-the-art scores across quantitative evaluations with FID and FVD, with as few as five neural function evaluations.

C2weakest assumption

That temporally adjacent video chunks serve as a practical proxy for true optimal couplings and produce straighter flows, and that injecting the inverted latent of the target chunk strengthens correspondences without introducing artifacts.

C3one line summary

FlowC2S generates video continuations by flowing directly from current to next frames in a fine-tuned flow model, using adjacent chunks as optimal couplings and target inversion to cut input size in half and beat SOTA FID/FVD scores.
