1 image input Split Stack - Nano Banana 2 + Kling 3.0
Upload 1 input image and generate 5 alternate angles to be used as start frames with Kling 3.0. Each video is stacked horizontally in a final 9x16 video.

简介
This ComfyUI tutorial workflow takes a single reference image and generates five alternate camera angles to use as starting frames for Kling 3.0 image-to-video. A set of utility nodes (including Reroute and PrimitiveNode) fans out your input from LoadImage into five branches, where a preconfigured "Nano Banana 2" angle-synthesis group produces varied viewpoints of the same subject. Each start frame is saved via SaveImage so you can verify framing and subject integrity before video generation.
Each of the five frames is then sent to KlingVideoNode to create short motion clips guided by your prompt (e.g., orbit, pan, dolly). Finally, the clips are tiled into a single portrait output using CreateVideo and saved with SaveVideo. The stacker uses a horizontal strip layout inside a 9:16 canvas, so you can compare all five angles in one shareable video. Optional GeminiImage2Node can auto-caption the input image to augment your motion prompt; if not used, the workflow falls back to manual text from a PrimitiveNode.
This setup is practical when you need consistent, multi-angle starters for Kling 3.0 without hand-authoring separate variations.

Yes. The KlingVideoNode requires valid credentials. Enter your API key or session token in the node’s settings (or environment, if supported by your install) before running the video stage.
It’s a preconfigured angle-synthesis group that takes your single input image and produces five alternate viewpoints to use as start frames for Kling 3.0. This helps you preview different angles without manually crafting separate inputs.
Yes. The workflow is set up for five branches by default. You can duplicate or remove a branch after the Reroute fan-out, then update the tiling/stacking inputs going into CreateVideo so the composite matches the new count. Angle spacing controls (if exposed) live inside the Nano Banana 2 group.
The compositor tiles the five Kling outputs into a portrait canvas for mobile/social viewing. If you prefer landscape, change the aspect/size in the CreateVideo node (author presets include 720p/2K/16:9). Ensure all branches feed the compositor at the same resolution.
