Exploded View Animation
Upload an image of a device or object to generate start and end frames. The workflow animates the transition to an exploded view and back, outputting a seamless video loop.

简介
This ComfyUI workflow, titled 'Exploded View Animation,' is designed to transform a static image of a device or object into a dynamic video showcasing an exploded view. The workflow utilizes models such as Nano Banana 2 and Seedance 1.5 Pro to generate start and end frames, which are then animated to create a seamless loop. Key nodes like ByteDanceFirstLastFrameNode and CreateVideo are employed to handle the transition between frames, while SaveImage and SaveVideo nodes manage the output.
This workflow is particularly useful for visualizing complex mechanical structures or electronic devices, providing an engaging way to present internal components without the need for physical disassembly.

This workflow does not support audio. You can add audio by using a video editing tool after exporting the video.
Images of devices or objects with clear outlines and details work best, especially if you have a reference image of the internal components.
Enable the node for reference images of internal components to enhance accuracy, especially when precise internal structure is important.
Yes, you can save individual frames using the SaveImage node before compiling them into a video.
