Measured (table) lengths in the primary papers are 30 s (CausVid, LongLive, Rolling Forcing), 50/75/100 s (Self-Forcing++) and 50/250/300 s (Stable Video Infinity). Longer claims are qualitative figures or demos: 255 s (Self-Forcing++ Fig. 6), 240 s (LongLive appendix + demo page), over 2 min (Rolling Forcing Fig. 4), 1000 frames at 128 px (Diffusion Forcing, qualitative) and 8-14 min (SVI README). Self Forcing itself reports no quality measure beyond 5 s and states that degradation remains past the training length.
