      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.

      FAQ

      What inputs does Happy Horse 1.0 support?

      MaxVideoAI exposes Happy Horse 1.0 as one model with text-to-video, image-to-video, R2V reference images, and video-to-video edit workflows.

      Does Happy Horse support lip-sync?

      Yes. Happy Horse is treated as a native-audio model with synchronized speech and lip-sync integrated into the generation flow.

      Why is V2V priced differently?

      Happy Horse video edit is billed at a combined input/output rate, so V2V is double the standard per-second price for the same resolution.
