Tips and boundaries

Best practices, common fixes, and important limitations to help you get the strongest results with Happy Horse 1.0.

What works best

Use T2V for fresh ideas and spokesperson-style native audio shots.
Use I2V when a key visual or first frame is already approved.
Use R2V when identity, wardrobe, product shape, or character continuity matters.
Use V2V when the source clip has the right motion but needs a new look or direction.

Common problems → fast fixes

Feels random / inconsistent → simplify to: subject + action + camera + lighting. Re-run 2–3 takes.
Motion looks weird → reduce movement: one camera move, slower action, fewer props.
Subject drifts off-brand → start from a reference image and lock palette + lighting.
Text looks wrong → avoid readable signage, tiny UI, micro labels. Keep text off-screen.
Dialogue drifts → keep lines short and punchy; avoid long monologues.

Hard limits to keep in mind

Output is short-form (15s output (3-60s source for video edit)). For longer edits, stitch multiple clips.
Resolution tops out at 1080p for this tier.
No fixed seeds — iteration = re-run + refine.
