Seedance 2.0 (ByteDance) and Kling 3 (Kuaishou) are both per-second image-to-video models, but they optimize for different things. Seedance 2.0 leans into fidelity and features: it ships native audio for free and supports first/last-frame conditioning, which makes it a strong choice for polished hero shots. Kling 3 leans into efficiency and movement: it costs roughly a third of Seedance 2.0 per second at 720p and produces confident, dynamic motion, which makes it ideal for fast iteration and high-volume social output.
Neither model is strictly "better" — the right answer depends on the shot. This page breaks down the real credit math on Kensa, matches each model to concrete scenarios, and explains why running both from a single account lets you spend Seedance credits on your money shots and Kling credits on everything else.
