Kling 3.0 (Kuaishou) and Seedance 2.0 (ByteDance, routed via fal) are the two flagship video models on Lilidi AI. Kling is the lower cost per second and supports start and end frames; Seedance runs longer clips with native audio at a higher rate. Pick Kling 3.0: You are iterating a lot, you need to morph between a start and an end frame, or you want the lower cost per second on character driven shots. Pick Seedance 2.0: You need a single longer take, heavier motion complexity, or the most cinematic result and the higher per second cost is acceptable for a final. Verdict: Draft on Kling 3.0 because iteration is cheaper, then re run the approved shot on Seedance 2.0 when the take is final. Both bill from the same credit balance so switching costs nothing but credits. Provider: Kling 3.0 — Kuaishou (Kling); Seedance 2.0 — ByteDance Seedance, via fal. Max clip length in Lilidi: Kling 3.0 —
10s; Seedance 2.0 — 15s. Native audio: Kling 3.0 — Yes; Seedance 2.0 — Yes. Start / end frame: Kling 3.0 — Start and end frame supported; Seedance 2.0 — Start frame and references.

Typical use: Kling 3.0 — Character scenes, narrative shorts, music videos; Seedance 2.0 — Cinematic ad shots, complex motion, hero b roll. Q: Why is Seedance more expensive? A: Seedance 2.0 is billed by the provider at a higher per second rate, and Lilidi passes that through in credits per second. Q: Can I use my own start image? A: Yes. Both models accept an uploaded start frame in the video editor. Q: Do both produce sound? A: Both support native audio; results vary by prompt and by whether the prompt describes dialogue or ambience.
