Four reasons to pick HappyHorse for speaking clips
Each row is a spend decision: language, sound pass, cast lock, or format cost — not a generic benefit list.
Direct the line in one of seven languages
Spell the dialogue in the prompt and name the spoken language. Lip-sync covers English, Mandarin, Cantonese, Japanese, Korean, German, and French — that exact set, not an open world list. Use it when a spokesperson cut, dubbed explainer, or localized ad must look spoken rather than captioned over frozen lips. If you need a language outside those seven, switch models or plan a post-dub path instead of hoping the mouth tracks.
Queue picture and sound in one joint pass
Alibaba’s ATH design synthesizes audio alongside the frames — dialogue, ambience, and Foley aimed at the same take rather than a silent render you always score later. A clip can return already scored and lip-synced when sound lands with the picture, but there is no separate audio on/off control, so do not bank on every file as a guaranteed soundtrack. Listen to the result before you ship client work.
Lock a cast with up to nine reference stills
Reference mode accepts up to nine images — not a source video. Point the prompt at [Image 1]…[Image 9] to pin a face, outfit, product pack, or palette across shots. That is how a short sequence keeps the same presenter without fine-tuning. Image-to-video is different: one required start frame, aspect derived from that frame, no separate aspect control. Do not upload a motion plate expecting video-to-video; that path lives on Seedance 2 and Omni Flash edit instead.
Pick length and resolution before you spend
Duration is an integer from 3 to 15 seconds. Resolution is 720p or 1080p only — no 4K on HappyHorse 1.1. Text and reference modes expose wide aspect choices; frames mode inherits aspect from the start image. Credits bill per second: 40 at 720p, 50 at 1080p, with a 120-credit floor so a 3s × 720p run is the cheapest legitimate clip. Read the live cost in the generator before you queue.
Speaking path
From script to a speaking clip in four decisions
Each step is a choice that changes cost, cast, or language — not a generic upload tutorial.
1
Choose text, first frame, or reference stills
Start from a written scene, animate one required start image, or attach up to nine reference stills for cast lock. Reference mode is image conditioning only — skip it if you have a source clip to drive motion.
2
Write the action and the spoken line
Put what happens and what is said in the prompt. Name the language when you need lip-sync in English, Mandarin, Cantonese, Japanese, Korean, German, or French. For reference mode, call out [Image 1]…[Image 9] so faces and products land where you intend.
3
Set 3–15s and 720p or 1080p
Match length to the line you need delivered. Leave 4K for another model. Confirm the credit quote — 40/s at 720p, 50/s at 1080p, never below 120 — before you spend.
4
Render, listen, then iterate the line
Queue the take and check mouth timing plus any returned audio. Tweak the dialogue, swap a reference, or re-roll the same cast into the next shot without leaving the generator.
Shelf check
When talking video beats silent motion models
Inputs, resolution caps, duration, and credit shape only — not quality rankings. Highlight stays on HappyHorse 1.1 when speech is the goal.
| Pick when | Character must speak; multilingual mouths | Need 4K or source-video conditioning | Want Google Veo fixed-length clips up to 4K | Need a fast draft or video-edit path |
|---|---|---|---|---|
| Input modes | Text · first frame · up to 9 ref images (no source video) | Text · image · video reference (v2v) | Text · image (t2v / i2v) | Text · image · video edit (v2v) |
| Resolution caps | 720p or 1080p only | Up to 4K (plus 480p–1080p) | 720p / 1080p / 4K | Duration-led (no 720p/1080p tier picker) |
| Duration control | User int 3–15s | User duration × resolution pricing | Fixed-length clips (~8s class) | User duration (default 8s) |
| Credit shape | 40/s @720p · 50/s @1080p · floor 120 | Per-second × resolution (4K highest) | Flat per-clip by resolution tier | 30 credits per output second |
| Speech / audio focus | Joint audio-video + 7-language lip-sync | Motion-first; not talking / lip-sync focus here | Not the multilingual lip-sync model | Speed / edit focus, not a lip-sync path |
Talking jobs
Jobs that need mouths that track dialogue
Personas built around speech, language markets, and cast continuity — not silent B-roll.
Founder on-camera announcement
Deliver a product line straight to camera with lip-synced speech so the launch cut does not need a studio day for a 10-second statement.
Localization producer
Ship the same explainer in Mandarin, Japanese, or German with mouths that match each language instead of hard-subbing a single English take.
Paid-social media buyer
Swap dialogue per market on a vertical 9:16 cut while keeping the same presenter locked from reference stills.
Course author
Turn a short lesson script into a narrated talking-head segment you can re-roll when the syllabus changes.
Product marketer
Animate a packshot still and pair it with spoken benefits so the demo explains itself without a separate VO session.
Character short director
Hold one cast across three beats with [Image 1]–[Image 9] refs so dialogue scenes stay the same face scene to scene.
Explore other video models

The only Seedance tier with 1080p and 4K — always-on synced audio, 4–15s from text, frames, or refs.

HappyHorse 1.1 questions before you generate
Which languages can HappyHorse 1.1 lip-sync?
HappyHorse 1.1 is set up for lip-sync dialogue across seven languages on SupaImagine. Pick the language that matches the line you want spoken so mouth motion and audio stay aligned.
Will every file include audible speech and lip motion?
The model is designed to synthesize sound with the picture and match mouths to dialogue, so many takes come back scored and lip-synced. Still preview each export before you publish — treat joint audio as the design goal, not a silent fallback mode.
How do text, first-frame, and nine-image reference modes differ?
Text mode builds the talking clip from a prompt. First-frame mode locks the opening look from one still. Reference mode accepts up to nine images to hold cast and costume continuity while you direct the line.
How do the 120-credit floor and per-second rates work?
Billing is 40 credits per second at 720p and 50 at 1080p. The cheapest legitimate run is 3 seconds at 720p (120 credits), which is also the floor. Longer or 1080p takes scale from there.
Does HappyHorse 1.1 go to 4K?
No. This model exposes 720p and 1080p only. If you need 4K delivery, finish composition here then upscale with a video tool or choose a 4K-capable model for the final pass.
What clip lengths are available?
Durations from 3 to 15 seconds. Set length with the dialogue so the line fits the window before you spend.
When is HappyHorse the right model versus a general t2v lane?
Open HappyHorse 1.1 when multilingual talking heads, character lines, or lip-synced UGC are the job. Use a general motion model when you only need silent or non-dialogue cinematic motion.
Are paid-plan HappyHorse clips cleared for commercial work?
Yes under a paid SupaImagine plan and the site Terms. Clear talent, logos, and music-like beds you do not own yourself.
