Seedance ComfyUI Workflows

The first thing to know about Seedance comfyui workflows is that Seedance is a cloud model. It is ByteDance's video-generation family from the Seed team, and there are no public weights to download, so these workflows call it through ComfyUI's API nodes rather than loading a checkpoint. What you get in return is one of the strongest video generators available: Seedance 2.0 has topped the blind text-to-video leaderboard on Artificial Analysis, where people vote on clips without knowing which model made them.

The workflows cover the jobs people actually reach for. Text-to-video turns a written prompt into motion, image-to-video animates a still you provide, and first-last-frame (FLF2V) interpolates between two frames you set. Seedance 2.0 generates synchronized audio in the same pass, so dialogue and sound effects land with the picture instead of being added afterward, and it can produce multi-shot clips up to about fifteen seconds. It also accepts a mix of reference inputs, several images plus short video or audio clips, to steer the result.

Because these are open ComfyUI graphs around a closed model, you still control the parts that matter: the prompt, the conditioning images or frames, the duration, and the aspect ratio, which ranges from wide 21:9 down to vertical 9:16. ByteDance describes Seedance's camera control and motion as director-level and physically plausible; those are the model's own claims, but the leaderboard result is independent.

To run one, open a Seedance workflow on Comfy Cloud with nothing to install, since there is no local weight option anyway. Add your prompt or upload your frames, set the duration and aspect ratio, and generate. You can re-run with a tighter prompt until the motion and timing are right.
