new.ip233.com｜seedance-2.0-720p 视频生成

720p is the resolution Seedance 2.0 was basically built around, and this node is the version that locks it in. It calls seedance-2.0-720p through the new.ip233.com relay, gives you the full 4–15 second duration range and all six aspect ratios, and returns a ready MP4. If you're going to use Seedance at all, this is the node most people should start on - it's the quality/cost balance point before the price curve climbs toward 1080p and 4K.

It's one of the Seedance 2.0 cluster in ComfyUI-Tikpan-Pro (the official plugin for Tikpan.com), and like every node in the new.ip233.com relay group it needs a key from https://new.ip233.com - not the Tikpan one. Seedance is ByteDance's closed video line, so there's no local model here at all; the relay is the only door, and every clip is metered.

How it works

POST a JSON payload (model: seedance-2.0-720p, prompt, duration, aspect ratio, optional refs) to https://new.ip233.com/v1/videos, poll the async task, download the finished MP4 to your output folder, return VIDEO + path + cloud URL + logs. The fixed-resolution design just means the model and resolution dropdowns are hidden - there's genuinely nothing else to misconfigure.

The inputs that matter

• 生成指令 - the prompt.
• 视频时长 - 4–15s in one-second steps. 6 is the default and a decent starting point.
• 画面比例 - 16:9, 9:16, 1:1, 21:9, 3:4, 4:3.
• 首帧图 / 尾帧图 - optional first/last frame pins.
• 参考图1 … 参考图9 - up to nine reference images.
• 视频URL列表 / 音频URL列表 - up to 3 + 3 optional URLs.

Plus the standard relay tail: 最长等待秒数 (600), 查询间隔秒数 (5), 校验HTTPS证书, 跳过错误.

Outputs

Gotchas

The enforced rule applies here too: first/last-frame mode is mutually exclusive with reference images, video URLs, and audio URLs - pick one, or the node rejects the request. And the standing economics: the community's loudest objection to Seedance-in-ComfyUI was "it's an API and it's expensive," and that objection is most accurate at the high-res end - which is exactly why 720p is the sane default. Iterate at 720p, save 1080p for the final deliverable. Test one short clip before you trust a batch run, since this pack's docs are thin and its community footprint is close to zero.
