视频｜Grok3 直出视频生成

xAI's Grok video is one of the more permissive closed video models you can reach from a graph - the KB's closed-models essay notes Grok's famously light content filtering - and TikpanExclusiveVideoNode is the pack's "direct out" Grok video node. The "exclusive" and "Grok3 直出" branding signals the intended workflow: run Grok's own prompt-optimizer node (TikpanGrokPromptOptimizerNode, elsewhere in this pack) on your brief, then feed the result here, because Grok responds much better to Grok-flavored prompts than to generic ones. It supports grok-video-1.0 and grok-video-1.5 (plus the older grok-videos / grok-video-3 / grok-video-3-10s aliases), 6/8/10/12/15-second clips, 480p/720p, and up to seven reference images.

How it works

The Grok3专属提示词 plus model, duration, ratio, resolution, seed, and up to 7 reference images go to the relay as an async video job; the node polls 任务ID until the clip renders, downloads it, and returns the standard 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 (VIDEO).

The inputs that actually matter

• Tikpan_API密钥 - sk- from tikpan.com (note the slightly different field name on this node).
• Grok3专属提示词 - the prompt. The tooltip recommends feeding it from the Grok prompt-optimizer node's output. Grok has its own prompt grammar; generic Stable Diffusion-style prompts waste its potential.
• 模型选择 - five options with sharp differences:
  • grok-video-1.0 - text/image/multi-reference (up to 7 images)
  • grok-video-1.5 - single-reference only (exactly 1 image, per the tooltip)
  • older grok-videos / grok-video-3 / grok-video-3-10s - legacy aliases.
• 视频时长 - 6 / 8 / 10 / 12 / 15 seconds.
• 比例 - 16:9 / 9:16 (default) / 1:1 - but the tooltip warns 1.5 only supports 16:9 and 9:16.
• 分辨率 - 480p or 720p. No 1080p tier on this node.
• 随机种子 - 888888 default; same seed + same prompt aims to reproduce a clip.

Optional: 参考图_1 … 参考图_7, 中转站地址 (defaults to tikpan.com), 校验HTTPS证书 (defaults true here), and 跳过错误.

Installing it

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

restart (or Manager → "Tikpan"). No models to download.

Where people get burned

• 1.0 vs 1.5 reference rules. 1.0 takes up to 7 images; 1.5 requires and caps at exactly 1. Wiring a multi-image batch into 1.5 is the classic error, and the ratio limits differ too (1.5 drops 1:1).
• The prompt optimizer matters. The "效果更佳" note in the node description isn't fluff - Grok video quality lives and dies on prompt phrasing. Use the optimizer node.
• No 1080p. If you need higher than 720p from Grok, this relay tier doesn't offer it.
• Seed is best-effort. Reseller relays don't guarantee determinism; treat the seed as a hint.

The fair take: if you're doing Grok-native short-form video - and especially if you want the least-filtered closed model available - this is the node, with the optimizer node as its intended front half. Just respect the 1.0/1.5 reference and ratio rules.
