Best Image-to-Video API: Seedance 2.0 vs Kling

TL;DR For cheapest + fast, use Seedance 2.0 Fast. For the most capable image-to-video — native audio, multimodal reference (images / video / audio) and rich inputs — use Seedance 2.0. For motion transfer (drive a character with a reference video), use Kling Motion Control. All three are callable via the apimodels.app unified API.

Model	Price	Resolution	Duration	Native audio	Input
MiniMax H3	2K $0.145/s	2K	5-15s	✅ native	text / image / multimodal (≤9 img, ≤3 vid, ≤3 audio)
Seedance 2.0	480p $0.092/s · 720p $0.197/s · 1080p $0.492/s	480p / 720p / 1080p	4-15s	✅ native	text / image / multimodal (≤9 img, ≤3 vid, ≤3 audio)
Seedance 2.0 Fast	from $0.071/s	480p / 720p	4-15s	✅ optional	text / image / multimodal (faster & cheaper)
Kling Motion Control	720p $0.06/s · 1080p $0.10/s (Kling 2.6)	720p / 1080p	up to 30s	—	reference image + video (motion transfer)

How to choose by use case

• Budget / high-volume drafts: Seedance 2.0 Fast (480p $0.12/s, full multimodal).
• Quality + native audio / multimodal reference / real people + assets: Seedance 2.0 (≤9 img, ≤3 vid, ≤3 audio, native audio).
• Motion transfer (drive a character with a reference video): Kling Motion Control。

All three are callable through the apimodels.app unified video API: one API key, POST /api/v1/video/generations, pay-as-you-go, reachable anywhere.

Frequently Asked Questions

Which image-to-video API is cheapest?

By per-second rate, Seedance 2.0 Fast is cheapest (starting at 480p). Kling Motion Control is $0.06/s at 720p but is motion-transfer (a different use case). For general image-to-video, Seedance 2.0 Fast offers the best value.

Which image-to-video API is the most capable / best quality?

Seedance 2.0 is the most capable of these: native synchronized audio, plus text / image / multimodal reference (up to 9 images + 3 videos + 3 audios), with natural motion and strong prompt adherence — best when you want finished-quality output and rich inputs. For a cheaper, faster option, use Seedance 2.0 Fast.

Which supports native audio?

Seedance 2.0 generates synchronized audio alongside the video; Seedance 2.0 Fast has optional generate_audio; Kling Motion Control has no audio.

What if I need multimodal input (multiple images / reference video / audio)?

Use Seedance 2.0: it accepts up to 9 reference images, 3 reference videos and 3 reference audios combined — ideal for real people + assets and complex scenes.

How do I call these image-to-video APIs?

Sign up at apimodels.app for one API key and call them all via POST /api/v1/video/generations with the model name (seedance-2.0 / seedance-2.0-fast / kling-motion-control) — directly reachable from anywhere.
