The Video Generator node runs an AI video model and produces a video as output. You can drive it with a text prompt, an image-to-video workflow where a reference image is animated, or a full pipeline where upstream nodes produce both the prompt and the starting frame automatically.

​
Available models

The model picker lists all enabled video models in your workspace. Two models are available by default:
  • Kling V3 — a text-to-video and image-to-video model. Three variants are available depending on the motion style you need.
  • Seedance 2.0 — a high-quality model for image-to-video and text-to-video workflows.
Seedance 2.0 requires a Business tier subscription. Workflows that include a Seedance 2.0 node show a lock badge on the template card if your account is on a lower tier.
Your workspace administrator can add more video models through the Node Builder.

​
Input sockets

The sockets available depend on the selected model. Common inputs include:
SocketTypeDescription
prompt-inText (orange)The generation prompt
image-inImage (pink)Starting reference image for image-to-video
end-image-inImage (pink)Ending frame for morphing workflows
audio-inAudio (cyan)Audio track to incorporate into the video
params-inAny (purple)Parameter bundle from a Request Input node
Switching models updates the socket set. The node attempts to reconnect existing wires to compatible handles automatically.

​
Output sockets

The video-out socket on the right side emits the generated video. Connect it to a Response Output to return it to an API caller, or to a Frame Extractor node to continue processing frames.

​
Controls on the node

First row
  • Model picker — select the active model.
  • Aspect ratio dropdown — available options depend on the model (for example, 16:9, 9:16, 1:1).
Second row
  • Duration dropdown — available durations depend on the model (for example, 3 s, 5 s, 10 s). Kling V3 supports up to 15 s.
  • Resolution dropdown — appears on models that expose resolution presets.
  • Sound effects toggle — appears on models that support AI-generated audio (for example, Kling V3). When enabled, the model generates ambient sound to match the video.
  • Settings icon — opens the side panel for advanced configuration.
  • Run button — run the node.

​
Credit cost

The node header shows the estimated credit cost for the current settings (for example, ~56 cr). For per-second-priced models like Kling V3, the displayed cost reflects the selected duration (for example, 5 s × rate).

​
Side panel inspector

Click the Settings icon to open the side panel. From there you can:
  • Upload start and end reference images with large tile pickers
  • Edit the prompt in a full-width text area
  • Adjust advanced parameters exposed by the model
  • Choose output format settings

​
Generation history

Past results are stored on the node. Use the arrow controls below the preview to navigate between generations, or click All for the full-screen gallery.
Chain an Image Generator into a Video Generator to animate a freshly generated image. Connect the image-out socket of the Image Generator to the image-in socket of the Video Generator.
