| Seedance 2.0 Fast | from $0.071/s | 480p / 720p | 4-15s | ✅ optional | text / image / multimodal (faster & more affordable) |
| 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 $0.071/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 most affordable?
By per-second rate, Seedance 2.0 Fast is most affordable (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 more affordable, 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.
