Can I use HappyHorse inside a reel?

It is available on the standalone video tool but not published to the reel pipeline. Reel requires models that bind character references directly; HappyHorse reads only a start frame, so the face can drift from shot two onward.

Which models do handle dialogue inside a reel?

Seedance 2.0 — it does lip sync as well and binds up to nine references, so it holds the character across shots at the same time.

Do I supply the audio?

HappyHorse generates its own. Passing a reference audio track is a provider capability that Reelfo does not currently expose.

HappyHorse 1.0

HappyHorse 1.0 is a lip-sync-oriented video model. Most video models treat a talking head as a body that happens to move its mouth; HappyHorse treats the dialogue as the driver. For a reel with actual spoken lines, that difference is the whole shot.

How It Works

Key Features

Lip Sync as the Point

Mouth movement tracks the spoken line instead of approximating speech. The uncanny quality of AI dialogue usually lives in that mismatch.

Native Audio Output

Returns a clip with sound rather than a silent one to dub afterwards.

Start-Frame Driven

Takes a keyframe as its anchor, so Reelfo generates one first. That also means it holds a character within a shot but not across shots — for cross-shot identity, use a reference-binding model.
