Seedance2.0 Real Human: FLF2V is a ComfyUI workflow that verifies a real person’s identity once and then generates a personalized video where both the first and last frames are constrained by your chosen references. It uses ByteDanceCreateImageAsset to upload and verify a reference photo, returning an Asset or Access ID and a Group ID to keep all assets for the same person linked. Video generation is handled by the ByteDance2FirstLastFrameNode, which calls the Seedance 2.0 FLF2V model to condition the opening and closing frames while smoothly interpolating motion in between. PreviewAny lets you inspect results in-graph, and SaveVideo writes the final clip to disk.
