EvoLink Seedance 2.0 Mini Image-to-Video (Official)

Image-to-video is the most controllable kind of cloud video, and Mini is the cheapest flavor of it in the EvoLink pack. EvoLink Seedance 2.0 Mini Image-to-Video (Official) takes a required first_frame, an optional last_frame, and a prompt, and gives you a 4-to-15-second clip capped at 720p. If you want to learn first/last-frame animation without spending flagship money on every attempt, this is the node to make your mistakes on.

What it is

• first_frame (required) - the starting image from any image output. Local files upload through EvoLink's channel and are auto-deleted after 72 hours. The clip's aspect ratio follows this frame.
• last_frame (optional) - the ending image; connect it and the video is forced to travel from frame A to frame B. Mismatched ratios auto-align to the first frame.
• prompt (required) - the motion description, Chinese welcome.
• duration - 4–15 seconds, default 5, billed by duration.
• quality - 480p or 720p. Mini has no 1080p/4K - that's the point of the tier.
• generate_audio - on by default, no extra charge.

Outputs: video (into Save Video - nothing visible otherwise), task_id, status_info, result_urls (24-hour expiry), response_json. Default timeout 30 minutes; renders are remote, so "Mini" means cheap, not instant.

Install and key

Standard EvoLink install - same for every node here. ComfyUI Manager → search EvoLink → install → full restart (close the console, don't just refresh the browser). Manual:

cd ComfyUI/custom_nodes
git clone https://github.com/deeplearning-goethe/comfyui-evolink

Dependency is just requests; no models, no GPU. Key from evolink.ai/dashboard/keys (sk-), pasted once into api_key - saved locally, blank after, never in a shared workflow.

Why you'd specifically pick Mini

Two reasons. First: it's the cheap way to iterate on "will this frame move well" before you commit the good frames to a pricier render. Second: the loop trick - feed your first frame as the last frame too, and Mini becomes the cheapest loop generator in the pack, because the model has to return to where it started. It won't be your most polished loop ever at 720p, but it'll be your cheapest, which is often the point.

The trade is the same one the whole Mini line makes: it's visibly a budget render, so finals belong on the full Seedance 2.0 I2V. And the standing cloud math applies - per-call billing, prompts and frames leave the machine, failed or moderation-blocked tasks don't charge. Cheap tier, real meter, same deal.
