pub const DEFAULT_MIN_FRAMES: usize = 4;Expand description
Sampling floor and ceiling, also from the checkpoints’ own video processor
(min_frames: 4, max_frames: 768). The floor matters more than it looks:
with temporal_patch_size = 2, fewer than 2 frames cannot fill a single
temporal group, and a 1-frame “video” would silently become a still.
