SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @runcomfy/cli.

What problem does it solve? Turning a single approved still image into a short cinematic video clip normally requires manual animation work or complex video tooling; this Skill lets you generate a 4-30 second 720p clip with optional synchronized audio directly from the command line using ByteDance Seedance 2.5 on RunComfy. ## Core Features & Use Cases - Single-image animation: Submit one image URL plus a motion prompt to the bytedance/seedance-2.5/image-to-video/720p endpoint; the output aspect ratio follows the input image. - Native audio generation: Set generate_audio: true to produce synchronized speech, sound effects, and ambience in the same pass. - Routing guidance: Documents when to use sibling endpoints instead, such as the cheaper 480p draft tier, text-to-video, reference-to-video, or first-last-frame. - Use Case: A marketer has an approved product packshot and needs a 12-second silent clip with a slow camera push-in for an ad variant; the Skill submits the job, polls status, and downloads the result to a local directory. ## Quick Start Ask the agent to animate your image by saying: animate this still image into an 8-second video with Seedance 2.5 image to video using a slow push-in camera move and soft ambient audio.

FAQPage Schema
How do I animate a still image into a video with Seedance 2.5?▼

Run `runcomfy run bytedance/seedance-2.5/image-to-video/720p` with a JSON input containing a motion prompt and a publicly reachable image URL. The CLI submits the job, polls until completion, and downloads the video to your specified output directory.

What input fields does Seedance 2.5 image to video accept?▼

The schema has exactly four fields: prompt (required string), image (required URL), duration (optional integer, 4-30 seconds, default 5), and generate_audio (optional boolean, default true). There is no aspect_ratio, resolution, seed, or multi-image input.

How much does Seedance 2.5 image to video cost per second?▼

The 720p endpoint bills at $0.35 per second of generated video, so a default 5-second clip costs $1.75 and a 30-second maximum clip costs $10.50. A 480p sibling endpoint runs the same schema at $0.17 per second for cheaper drafts.

Can I control the aspect ratio of the generated video?▼

No, the output aspect ratio always follows the input image and there is no aspect_ratio parameter. To get a different ratio, crop or reframe the source still before submitting it.

When should I use reference-to-video instead of image-to-video?▼

Use Seedance 2.5 Reference-to-Video when you need multiple image, video, or audio references in one shot or an explicit aspect-ratio control. The image-to-video endpoint accepts only one still image and a motion prompt.

Why does my Seedance video generation fail with a schema error?▼

Exit code 65 indicates bad input JSON or a schema mismatch, usually from passing unsupported fields like aspect_ratio, resolution, or seed. Stick to the four documented fields and ensure the image URL is publicly reachable without login-gated hosting.
