Pick for: extending Veo Fast clips at matching latency tier. For dedicated treatment of extend (input video preparation, frame anchor strategy, chained extends), see the [ video extend ](https://www.skills.sh/agentspace so/runcomfy agent skills/video extend) skill. t2v Route 1: HappyHorse 1.0 — default Model : happyhorse/happyhorse 1 0/text to video Catalog : [happyhorse 1 0](https://www.runcomfy.com/models/happyhorse/happyhorse 1 0/text to video?utm source=skills.sh&utm medium=skill&utm campaign=ai video generation) Currently 1 on the [Artificial Analysis Video Arena](https://artificialanalysis.ai/text to video) — RunComfy's recommended default for general purpose t2v. Native synchronized audio is generated in pass (no separate Foley step). Schema Field Type Required Default Notes prompt string yes — Subject first, describe motion + scene + audio in one declarative duration int no 5 Seconds. Up to ~15s aspect ratio enum no 16:9 16:9 , 9:16 , 1:1 typical resolution enum no 1080p 720p , 1080p seed int no — Reproducibility Invoke Prompting tips Lead with subject and one main action. "A red kite tumbles across a beach" — verb driven, not adjective stacked. Describe audio inline — "Audio: wind, gulls, distant laughter." HappyHorse generates audio in pass. Motion language matters more than visual nouns — "tumbles", "drifts", "snaps into focus" "looks beautiful". Multi shot: describe transitions explicitly — "Then the camera cuts to …" — Arena leading multi shot consistency. t2v Route 2: Wan 2 7 — open weights + audio driven lip sync Model : wan ai/wan 2 7/text to video Catalog : [wan 2 7](https://www.runcomfy.com/models/wan ai/wan 2 7?utm source=skills.sh&utm medium=skill&utm campaign=ai video generation) · [ wan models collection](https://www.runcomfy.com/models/collections/wan models?utm source=skills.sh&utm medium=skill&utm campaign=ai video generation) Pick Wan 2 7 when you have a specific voiceover / dialog audio file and want the on screen subject's mouth to sync to it. The audio url field drives the lip motion. Invoke With audio driven lip sync: Plain t2v (no audio): Prompting tips For lip sync , the prompt describes the scene + speaker ; the audio file drives the mouth. Don't transcribe the audio into the prompt — it'll fight the audio track. Open weights advantage : pair with Wan ecosystem (LoRA finetuned variants) when available. t2v Route 3: Seedance v2 — multi modal cinematic Model : bytedance/seedance v2/pro (or /fast ) Catalog : [seedance v2 Pro](https://www.runcomfy.com/models/bytedance/seedance v2/pro?utm source=skills.sh&utm medium=skill&utm campaign=ai video generation) · [ seedance collection](https://www.runcomfy.com/models/collections/seedance?utm source=skills.sh&utm medium=skill&utm campaign=ai video generation) Pick Seedance v2 Pro when the user needs multi modal conditioning — up to 9 reference images, 3 reference videos, 3 reference audio tracks synthesized in pass with cinematic motion refinement. Invoke Prompting tips Lens / film language is honored — "35mm anamorphic", "shallow DoF", "soft halation", "Kodak 5219" all land. Multi ref: describe roles explicitly — "subject from ref image 1, mood from ref video 2, score from ref audio 1" . Cinematic motion verbs: "tracking shot", "push in", "dolly out", "rack focus". i2v Route A: HappyHorse 1.0 I2V — default Model : happyhorse/happyhorse 1 0/image to video Catalog : [happyhorse 1 0 i2v](https://www.runcomfy.com/models/happyhorse/happyhorse 1 0/image to video?utm source=skills.sh&utm medium=skill&utm campaign=ai video generation) Invoke Prompting tips Describe motion , not the scene the image already shows. The image is your scene; the prompt is your direction. Anchor the camera explicitly — "Camera stays still" prevents drift; "slow push in" gives intent. Audio in the same prompt as t2v Route 1. i2v Route B: Veo 3 1 — Google's flagship Model : google deepmind/veo 3 1/image to video (or /fast/image to video ) C
