Cloth and hair motion that holds together
Hair and fabric are where temporal coherence breaks first. Prompt cues for weight and stiffness, shot choices that hide it, and when to mask and regenerate.

Hair and fabric are where temporal coherence breaks first. Prompt cues for weight and stiffness, shot choices that hide it, and when to mask and regenerate.
A short dissolve at the join is the standard fix for exposure and identity drift between chained clips. Dissolve lengths, and when a hard cut still wins.
A still-image inpaint does not fix a moving hand. Three video options: masked inpaint, a short segment retake, or reframing the hand out of shot.
Feet skate because ground contact is never specified. Prompt phrasing for footfall, weight and surface, plus the shot sizes where walking actually holds up.
Printed graphics, stripes and logos are the first thing a video model reinvents frame to frame. Mask that region and inpaint it instead of rerolling the shot.
Sharpening an upscale past a conservative setting amplifies temporal noise. Stabilize the clip first, then upscale gently so flicker dies instead of blooming.
Some models reach 2K by regenerating a low-res render; others generate high-res natively. What each does to fine detail, temporal stability and render time.
A 15-second ceiling is rarely 15 usable seconds. The three ways long clips fall apart, a ladder test to find your safe duration, and where to place the cut.
Background people break more shots than hero subjects. The pixel budget that predicts failure, plus staging tactics for street, stadium and venue shots.
Shimmer is usually a frame-rate problem: too many frames starve temporal context. Rates that hold, where the deflicker pass goes, and how to spot compression.
An unblinking subject is the tell that survives every other fix. Schedule eye behaviour in the prompt, or chain short clips at natural blink points.
Seedance 2.5 and Wan 3.0 chase 30-second single takes, Flux 3 ships 20s with audio. Why duration is hard to ship, and how to hit 30s on Versely today.
Why hands, teeth, and signage remain the hardest surfaces for AI video and image models — and the shot design that routes around each failure.
The unit of AI video generation is no longer one shot. A look at models cutting between angles mid-generation, and why the third cut is usually where it breaks.
