This workflow allows you to generate up to four clips with WAN 2.2 and seamlessly combine them into a longer video of up to about 20 seconds.The workflow uses the SVI 2.0 Pro nodes and the SVI LoRA to generate smooth transitions by using the last few frames of the previous clip, as well as the initial start image, as character and environment references.I am using an RTX 5080, but with lower resolutions the workflow should also work well with GPUs that have less VRAM. <h3 id="additional-features">Additional features</h3><ul><li>Interpolation and upscaling</li><li>Switching between multiple WAN base models</li><li>Color matching to the reference image</li><li>Trimming the sides of the video to remove artifacts</li><li>Trimming a set number of frames from the first clip, so the video can begin with movement</li><li>Viewing and saving the last frame of each clip</li><li>Viewing all frames in a clip</li><li>SageAttention integration</li><li>Setting specific LoRAs as global for all clips (The SVI and lightx LoRAs are mandatory for the workflow to function.)</li></ul><h3 id="recommended-use">Recommended use</h3>Upload an image, set a lower resolution in the CustomResolution node, and select only one clip to be generated. The CustomResolution node was made by me and works with ComfyUI Manager.Turn off interpolation for now. Upscaling can remain enabled, as it will not have any effect unless upscaling itself is activated.Then iterate by generating a new seed or changing the prompt and LoRAs until you are happy with the result. After that, consecutively add clip 2-4. Remeber to activate “save output” for clips you want saved.Once you are happy with the full sequence, you can move to higher resolutions and then interpolate or upscale the final result.Note:You can disregard the aspect ratio setting in the CustomResolution node, as the workflow automatically adapts to the aspect ratio of the start image.Also, only the resolution setting for clip 1 matters. This setting is automatically carried over to the subsequent clips.<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/95ccc9ef-4ba4-4dc8-9b5c-fe8022e2d5e5/original=true/95ccc9ef-4ba4-4dc8-9b5c-fe8022e2d5e5.jpeg" />
