Video Gen

The Video Gen node runs a video model on a prompt and produces a video for the next node to use. You pick the model and write the prompt. Depending on the model you choose, the node can also accept reference media, such as a starting image, to guide the generation. Both the prompt and the model’s parameters can be set on the node or fed in from upstream nodes.

​

Inputs

Input handles are on the left of the node. The exact set depends on the model you select — the node shows a handle for each of that model’s available parameters.

​

Outputs

Output handles are on the right of the node. One video generation call produces one output item. If the Video Gen node receives multiple input items from a Batch or structured list, it runs once per item and produces one output item per run.

​

Settings

• Model — the video model that runs. Filtered to models that produce video output.
• Prompt — the text instruction the model generates from. A {{variable}} token exposes a dedicated text handle so upstream values can fill that part of the prompt.
• Connected parameters — any extra inputs the selected model exposes (reference media, aspect ratio, duration, and similar) appear as fields on the node. The exact set changes with the model.
• Advanced Settings — less-common model parameters under a collapsible section. The available parameters depend on the selected model.

Switching models keeps any compatible parameter values and fills in defaults for the new model’s parameters.

​

When to use

Reach for Video Gen whenever a step should produce a video — turning a text prompt into a clip, or animating a reference image the upstream flow created. Pick the model that matches the style, length, and inputs you need.

​

Connects to

• Upstream — Input nodes feeding the prompt; an LLM node producing a refined prompt; an Image Gen node producing a reference/start image.
• Downstream — a Result node to surface the video as a workflow output, or any node that accepts a video (or file) input.

​

Notes / limits

• The output is a single video handle labeled Video.
• Video Gen can run by itself from the node’s Run action when its required inputs are available.
• Video generation typically takes longer and costs more than text or image steps; runs can take a while to complete.
• A Batch, multi-select Choose Output, or LLM structured list makes Video Gen run once per incoming item. See Lists & single values.
• Connection compatibility follows the standard rules: exact-type matches connect, any connects to anything except tool-list, and media types can feed a file target.
• As with the rest of the canvas, no cycles or self-connections.
