new.ip233.com｜Grok Video 1.5 单图生视频

Single-image-to-video with xAI's Grok, with a rule you can't miss: this node takes exactly one reference image, no more, no less. You wire one IMAGE into 参考图, write a motion prompt, pick a duration and resolution, and the node sends it to the grok-video-1.5 model through the new.ip233.com relay and returns a saved MP4 plus a VIDEO output you can preview right in the graph. It's the "one subject, one shot, animate it" tool - product closeups, character stills, a single frame you want alive.

It's part of ComfyUI-Tikpan-Pro (official plugin for Tikpan.com), but this node lives in the pack's new.ip233.com relay group, so it needs its own sk- key from https://new.ip233.com - not the Tikpan one. The model itself is closed; the relay is your doorway, and you're paying per video.

How it works

The node converts your reference image to a JPEG data URL, POSTs to https://new.ip233.com/v1/video/generations with model: grok-video-1.5, then polls the task every few seconds until it's done, downloads the finished MP4 into your ComfyUI output folder, and hands back the local path, the cloud URL, and a VIDEO tensor. Because it's an output node, it's meant to sit at the end of your workflow.

The inputs that matter

• 参考图 - the required single image. The tooltip is blunt: 必填且只能 1 张参考图. Wire exactly one.
• 生成指令 - the motion prompt. English works; the default is a cinematic "smooth natural motion" prompt.
• 视频时长 - 4, 6, 8, 10, 12, or 15 seconds.
• 分辨率 - 480p or 720p. For a 15-second clip, 720p is the one you actually want.
• 画面比例 - only 16:9 or 9:16. No square, no 21:9.

The usual relay knobs are in optional: 最长等待秒数 (default 300), 查询间隔秒数 (5), 校验HTTPS证书 (off), and 跳过错误 (return empty on failure so a flaky relay doesn't abort the run).

Outputs

Five of them, and the last is the prize:

• 视频输出 - a VIDEO tensor you can preview or pipe to a video-save node.
• 本地保存路径 - where the MP4 landed (ComfyUI's output dir, named new_ip233_grok_video_15_<taskid>.mp4).
• 视频云端直链 - the cloud URL, in case you want to host or share it directly.
• 任务ID / 完整日志 - diagnostics.

Install

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

or ComfyUI Manager → Tikpan → Install → restart. Stock dependencies only - requests, PIL, torch.

Gotchas

The one-image rule is enforced by the relay, not just hinted at: wire in two reference images and expect a rejection. And because it's an output node, 跳过错误 genuinely matters - with it off, a failed job raises and marks the run failed; with it on, you get an empty video output and a log entry instead. Budget the cost before you burn ten 15-second 720p clips in a row; video is where API metering gets expensive fast. And as always with this relay group: an obscure, thinly-documented pack - read the log before you assume a failure is your fault.
