Animate a single still image into a 4-30 second 720p cinematic clip with optional synchronized native audio using ByteDance Seedance 2.5 Image to Video on RunComfy. Documents the four-field schema (prompt, image, duration, generate_audio), the $0.35/s pricing, the fact that output aspect ratio follows the input image, and when to route to the Seedance 2.5 480p, text-to-video, reference-to-video or first-last-frame pages instead. Calls `runcomfy run bytedance/seedance-2.5/image-to-video/720p` through the local RunComfy CLI. Triggers on "seedance 2.5 image to video", "seedance image to video", "seedance i2v", "animate this image with seedance", "bytedance image to video", or any explicit ask to turn a still into video with Seedance 2.5.
