Generate from text, animate an image, guide a scene with up to nine reference images, or edit an existing clip from the same Happy Horse model card.
Best for Native-audio spokesperson and dialogue clips, Unified text, image, R2V, and V2V production workflows, and Reference-guided character and product consistency.

Technical overviewDetails
Workflows: Text-to-video, image-to-video, R2V reference-image generation, and video edit are exposed as one model in MaxVideoAI.
Duration: 3-15 s for generation outputs; video edit accepts 3-60 s source clips and caps output to the first 15 s.
Resolution: 720p or 1080p
R2V references: 1-9 images, addressed as character1 through character9 in the prompt.
V2V edit: One source video, optional reference images up to five, and audio handling set to auto or origin.
Audio: Native synchronized audio and lip-sync are treated as part of the generation.
Happy Horse 1.0 model demos
Review the model page clips for native audio, lip-sync, and video-edit behavior. Comparison pages intentionally stay text/spec focused for this launch.

Structured prompt (best for reliable results)
Separate information so the model can follow it consistently.
Structured = consistency. Use when you need reliable results.
Template (copy/paste)
Scene (plain language):
[Subject + setting + props + time of day. Add 2–3 distinctive visual anchors.]
Cinematography:
- Camera shot: [wide / medium / close-up, angle]
- Camera motion: [slow push-in / handheld / pan / tracking]
- Lens look + depth of field: [e.g., 35mm, shallow DOF]
- Lighting + palette: [key light + 3 palette anchors]
Actions (beats):
- [Beat 1: a small, visible action]
- [Beat 2: another clear beat]
- [Beat 3: a final beat in the last second]
Dialogue (optional):
[Keep lines short so they fit the clip length.]
Background sound:
[One sentence: ambience + key SFX. Keep it simple.]
Constraints:
No logos, no readable text, no subtitles/overlays.
Pro prompt (ultra-specific "film crew brief")
Use this when you need a very specific cinematic look or continuity across shots.
Pro = continuity. Use for precise, repeatable looks.
Template (copy/paste)
Project / intent:
[One-line goal. What should the viewer feel/understand?]
Subject:
[Who/what. Wardrobe/materials. 2-3 distinctive traits.]
Location / set:
[Where + time of day + weather. Add 3 visual anchors (specific nouns).]
Cinematography:
- Framing: [wide / medium / close-up] + [angle]
- Lens feel + depth of field: [e.g., 35mm natural, shallow DOF]
- Camera movement: [ONE move: slow dolly-in / handheld / pan / tracking]
- Composition: [centered / rule of thirds / negative space]
- Look (optional): [clean digital / subtle film grain / soft bloom]
Lighting & color grade:
- Key light: [soft window / golden hour / neon practicals / studio key]
- Contrast: [low / medium / high]
- Palette anchors: [3-5 anchors: "warm sunrise, teal shadows, amber highlights"]
Action (timed beats):
- Beat 1 (start): [visible action + camera behavior]
- Beat 2 (middle): [visible action + camera behavior]
- Beat 3 (end): [final action + end pose / reveal]
Sound (if supported):
- Ambience: [one line]
- SFX cues: [1-3 cues]
- Music (optional): [genre + intensity]
Constraints:
No logos. No readable text. No subtitles/overlays. No slow-motion. No jump cuts.
Storyboard prompt (multi-shot / shot list)
Use this when you want a mini-story in one clip. A storyboard prompt (aka multi-shot / shot list prompt) gives Sora clear timing, camera direction, and continuity. Also called shot-list or sequenced prompts.
Storyboard = beat timing. Use for mini-stories in one clip.
Template (copy/paste)
Storyboard / shot list prompt
Duration: [4/8/12s] • Aspect: [16:9 or 9:16]
Scene + continuity:
[Same subject + same location + same wardrobe/props + same lighting throughout.]
Shot 1 (0–2s):
[Framing + subject action + camera move]
Shot 2 (2–6s):
[Framing + subject action + camera move]
Shot 3 (6–8/12s):
[Framing + final action/reveal + camera move or settle]
Lighting + mood:
[Golden hour / soft daylight / neon night… + 2–3 palette anchors]
Sound (if supported):
[Ambience + 1–2 SFX cues + optional music vibe]
Constraints:
No logos. No readable text. No subtitles/overlays. No jump cuts. No slow-motion.
Demo prompt - Happy Horse 1.0
Audio on10s
A museum curator walks through a dawn-lit portrait gallery as painted faces come alive and change expressions. Smooth dolly camera, marble reflections, soft dust, surreal realistic atmosphere, cinematic lighting, 15 seconds, 16:9.
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.
