EvoLink Grok Imagine Image-to-Video (Official)

EvoLink_GrokVideoI2V is xAI's image-to-video node, and it has one thing nobody else in this pack's lineup does: a mode dial with a setting called spicy. Grok's image and video stack is known for running a lighter content filter than the other majors, and this node exposes that directly as three generation styles - normal, fun, and spicy - for when you want the tone of the result nudged somewhere bolder. It's the xAI personality you're paying for.

The task itself is straightforward: first image required, up to seven reference images total, and it generates a 6–30 second clip.

The inputs that matter

• image1 (required) - the first frame / primary reference. Connect Load Image here.
• prompt (required) - shot and motion description. The model has your subject from the images; this should be about what happens.
• mode - normal (default), fun, or spicy. This is the fun one; expect the fun/spicy variants to be looser in both content and composition.
• duration - 6–30 seconds, default 6, billed by duration.
• quality - 480p (default) or 720p. Budget note: Grok's I2V tops out at 720p in this node, so don't expect 4K.
• aspect_ratio - 16:9 (default), 9:16, 1:1, 3:2, 2:3.

image2 and image3 are optional additional references (up to seven with image_urls_text), and the pack-standard api_key + timeout_seconds (1200) round it out.

How it works

Standard pack mechanics: images upload through EvoLink's official file channel (auto-deleted after 72h, no third-party host), the job goes to POST /v1/videos/generations, and the pack polls until completion, downloading the clip as a VIDEO object. Wire video into a native Save Video node. You also get task_id, status_info, result_urls (24h expiry), response_json - the same five outputs as every video node here. Needs a recent ComfyUI for VIDEO output support.

Installing

Nothing heavy - no GPU, no model files, only requests:

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

Restart ComfyUI fully afterwards, or install through ComfyUI Manager by searching EvoLink.

Troubleshooting

Same error codes as the whole pack - 401 key, 402 balance, 403 access, 429 rate limit. VPN users: whitelist api.evolink.ai and files-api.evolink.ai. One Grok-specific thing worth knowing: spicy is relative, not a promise - xAI's moderation still runs on their servers, so if a prompt gets refused, tone it down and retry (blocked jobs don't charge). And if the clip comes back looking nothing like your reference image, check that image1 is actually connected; an empty first-frame socket changes the whole request.
