A video node shows only the handles its selected model can use, so the ports change when you switch models or variants. Which handle you wire to decides how the upstream asset is used.
Pairing rules
- A last frame only works alongside a starting frame. A last-frame-only run is rejected with “Starting frame and last frame must be used together.”
- Frames and reference images are mutually exclusive unless the model accepts both — for example Kling 3.0 Omni’s reference-to-video variant.
- Each model caps how many image and reference-image inputs it accepts. Wiring more than the cap is rejected.
Output handles
Shot chaining
To produce a multi-shot sequence:
- Create your first video node and run it.
- Add a second video node downstream.
- Drag from the first node’s Last frame output to the second node’s Starting frame input.
- Prompt the second node with how the action should continue.
Each shot picks up exactly from the previous shot’s last frame, so motion and composition stay consistent.
To carry a character or style across shots instead of an exact frame, wire the same image into every node’s Reference image handle. Last modified on August 21, 2026
