How to choose

Seedance 2 is the top performer across text-to-video, image-to-video, and video editing, edging out HappyHorse 1.0. Seedance 2 offers more aspect ratios (6 including 21:9 ultra-wide), excellent default output quality, and strong multimodal reference support with first/last frame workflows.

Choose HappyHorse 1.0 when you need native audio+lip sync, video editing mode, or ~87% cross-clip consistency for multi-shot narratives. HappyHorse's built-in audio and 7-language lip sync are unique features no other model offers.

Choose HappyHorse 1.0 for better overall quality — with native audio+lip sync, video editing mode, and ~87% cross-clip consistency. It's the better choice for most video generation tasks when compared to Kling 3.0's specialized controls.

Choose Kling 3.0 when you need explicit camera motion control (push/pull/pan/tilt/orbit), native 4K output, or the Motion Control API for reference-video-driven character animation. Kling is unmatched for directed filmmaking.

Seedance 2 is the clear winner for general quality — delivering better default visual quality, 6 aspect ratios, sound, and multimodal references at a competitive price. Kling 3.0 excels when camera motion control or 4K output is the priority, not for everyday video generation.

Choose Kling 3.0 when you specifically need camera motion control, native 4K, or the Motion Control API. Kling is specialized for directed filmmaking, not general-purpose video generation.

Seedance 2 offers far more features: 6 aspect ratios including 21:9 ultra-wide, multimodal references, per-second pricing flexibility, and strong multimodal input support. Veo 3.1's advantages are 4K support and default background audio at competitive pricing.

Use Veo 3.1 Fast (60 credits) for quick 8s clips with auto audio if Seedance isn't available or you specifically need 4K. Use Veo Quality for premium 4K delivery. For any serious video work where quality matters, Seedance 2 is the better choice.

Seedance 2 is the best choice: widest aspect ratio set (6 options including 21:9 ultra-wide for YouTube Shorts/TikTok/Reels), 1080p output, sound support, and excellent quality across diverse prompts. Its 6 ratios cover every social platform format.

Use Seedance 2 Fast for testing social hooks cheaply. Use HappyHorse 1.0 if you need native audio+lip sync for talking-head social content.

Seedance 2 produces the most polished product videos with strong I2V fidelity for product shots. Its 6 aspect ratios (including 21:9 for cinematic product reveals) give you maximum format flexibility. Multimodal references handle product consistency across angles.

Use Kling 3.0 for product reveals that need camera motion (slow push-in, orbiting shot) or 4K. Use HappyHorse 1.0 when you need native audio narration alongside product footage.

HappyHorse 1.0's ~87% cross-clip consistency makes it the best choice for multi-shot narratives. Characters, style, and lighting stay stable across cuts — combined with native audio, 7-language lip sync, and 15s duration, it's ideal for storytelling.

Use Kling 3.0 when the story depends on camera movement (dramatic push-in or pan). Use Seedance 2 when you need 21:9 cinematic framing.

Kling 3.0 is the only model in this set with explicit camera motion control (push/pull/pan/tilt/orbit) and a dedicated Motion Control API. For action sequences, dynamic shots, and directed camera movement, it's unmatched. Its native 4K output also ensures crisp detail in fast-moving scenes.

For general action generation without specific camera directions, HappyHorse 1.0 or Seedance 2 produce higher overall quality. Use Kling specifically when you need to control the camera.

Kling 3.0 (native 4K since May 2026) and Veo 3.1 (1080p/4K, 2x credits for 4K). HappyHorse and Seedance 2 currently cap at 1080p. For most social and web use, 1080p is sufficient — only use 4K for film, advertising, and large-screen production.

For 1080p work, Seedance 2 offers the best overall quality with 6 ratios and sound.

Seedance 2 Mini is the lowest-cost route at 15-30 cr/s with sound, broad ratio support, and reference inputs. It is best for testing and drafts. Seedance 2 Fast remains useful for faster 480p/720p exploration, and Veo 3.1 Fast is strong for fixed 8s clips.

For final quality, switch to Seedance 2 or HappyHorse once the direction is validated. Mini is best used to validate ideas cheaply, not as the default final delivery model.
