Question 1

Happy Horse vs Seedance 2.0 — what's the main difference?

Accepted Answer

Happy Horse (Alibaba) currently leads the Artificial Analysis Video Arena for both text-to-video and image-to-video on blind human preference, and generates audio + video jointly through a unified 40-layer transformer (1080p in ~40s on a single H100). Seedance 2.0 (ByteDance) leads on multimodal reference input — 9 images + 3 videos + 3 audio in one generation — and native beat-sync motion. Both produce 1080p with native audio.

Question 2

Which is better for international content with dialogue?

Accepted Answer

Happy Horse. Native multilingual lip-sync across Mandarin, Cantonese, English, Japanese, Korean, German, and French is its standout feature. Seedance 2.0 generates native audio too but doesn't expose the same multilingual lip-sync range.

Question 3

Which is better for music videos?

Accepted Answer

Seedance 2.0. Native beat-sync motion locks video edits to a reference audio track. Happy Horse generates synchronized audio with the video but doesn't offer beat-locked editing to an external track.

Question 4

Which is better for reference-driven scenes?

Accepted Answer

Both support reference images, but at different scales. Happy Horse takes up to 9 reference images and resolves them via character1…character9 prompt tokens (good for multi-character scenes). Seedance 2.0 takes 9 images plus 3 reference videos and 3 reference audio in a single call — wider modality, more references.

Question 5

Which is cheaper per second?

Accepted Answer

Happy Horse: $0.14/s at 720p, $0.28/s at 1080p; video-edit mode is double rate. Seedance 2.0: $0.211/s at 720p and $0.486/s at 1080p. Both bundle into your plan's credits inside Flik AI.
