new.ip233.com｜Seedance-2.0 视频生成

TikpanCangyuanSeedance20Node is the full Seedance 2.0 model behind a new.ip233.com relay, and it's the slightly fancier sibling of the Mini node: same async /v1/videos submit-and-poll pattern, but the 特惠 ("special-price") model tier with first/last-frame support and multi-reference material. If you've read the Mini article, you already know the shape - this is the same node with a better model dialed in. ByteDance's whole Seedance line is API-only (the KB's ByteDance panel calls it out: flagships ship closed, everything underneath ships open), so this wrapper is how that quality gets into a ComfyUI graph at all.

How it works

Identical machinery to the rest of the Cangyuan video nodes: POST prompt + settings to new.ip233.com/v1/videos, get a task_id, poll until the job resolves, download the mp4 to your output folder. You get the same five outputs - 本地保存路径, 任务ID, 视频云端直连, 完整日志, and 视频输出 (a VIDEO you can preview or save). Don't be fooled by the is_output_node flag being true in the schema; the 视频输出 wire is the one that matters for your graph.

The inputs that actually matter

• API_密钥 - from new.ip233.com, not tikpan.com. Different relay, different key. This is the #1 beginner mistake with the whole category-08 group.
• 生成指令 - the prompt. Seedance handles longer, more detailed instructions than most, so give it motion, camera moves, lighting, and subject behavior.
• 视频时长 - 4–15 seconds, default 6.
• 画面比例 - six choices from 16:9 down to 3:4.
• 分辨率 - 480p or 720p only. If you need 1080p you're on the wrong node.

Optional: 首帧图 / 尾帧图 for bookend control, up to 4 reference images (参考图1–4), 3 video URLs, 1 audio URL, and 生成原生音频 - Seedance generates its own audio, on by default. Default 校验HTTPS证书 is false on this relay (same quirk as its siblings).

Installing it

Part of the ComfyUI-Tikpan-Pro pack:

cd ComfyUI/custom_nodes
git clone https://github.com/htrert/ComfyUI-Tikpan-Pro

or search "Tikpan" in ComfyUI Manager and Install. Restart after either. There are no model downloads and no GPU requirement - this node only needs outbound network access to the relay.

Where people get burned

• Metered spend. Seedance 2.0 is billed per clip; 15-second 720p jobs add up fast, which is exactly the objection the community keeps raising about every closed video model behind an API (see the KB's API-nodes essay for the canonical "extremely expensive" thread). Use Mini for drafts, save the full model for the shots that need it.
• Key mixups. new.ip233.com key in a tikpan.com node (or vice versa) → auth failure. Check the log.
• Long waits. Default timeout is 600s and polling every 5s; a big job legitimately takes minutes. The 最长等待秒数 / 查询间隔秒数 knobs are local, so you can tune them without touching the upstream.
• Your inputs leave the machine. Prompt and reference images go to a third-party relay server you don't control. Fine for product content; think twice for anything sensitive.

If you want ByteDance-grade video inside ComfyUI and the cost-per-clip is acceptable, this is the node. It's the same wrapper family as the Mini, just pointed at the better model.
