<h3 id="version-1.1">Version 1.1</h3>This version adds an image loader for adding key frames. Key frames can be selected by using the camera movement command "Go to image 2" to end on the second image in the key frame selection box. You can still make loops by going to the "original image" or, if you prefer, "go to image 0". Lightning can now be turned off and on with a single selection, and the number of steps will automatically be adjusted. SVI is also available, but it often has side effects like severe color shifts.All videos posted were created with lightning on, but turning if off improves maintaining style and smooth animation. If quality is important, test animations with lightning on, but turn it off for the final generation.By default, interpolation is set to 1, which doubles the rendering speed, but even higher quality is available by setting it to 0.<h3 id="version-1.0">Version 1.0</h3>This workflow is a variation on the amazing work of <a target="_blank" rel="ugc" href="https://civarchive.com/user/Usako_USA">https://civarchive.com/user/Usako_USA</a> and their Wan2.2 Highspeed "FreeLength(Loop Processing)" I2V Workflow for Your Scenario (v1.1). Cosmetic changes are removing the LLM calling for suggestions, and combining several nodes into subgraphs to keep the flow clean. I also added some notes about what certain settings are for.Functional changes are:<ul><li>Add a camera movement "Return to original image" that makes the last frame of that segment the original image, useful for loops or to reset quality.</li><li>Switch from KSampler to SamplerCustom to allow full sigma control, this reduces image degradation as the video lengthens.</li><li>Added a rescale multiplier to the model to slow video degradation even more.</li><li>Automated some of the manual settings.</li><li>Fixed bug when new image size is not a multiple of 8 that caused the video to jiggle between scenes.</li></ul>The images contain the workflow settings I use to make the video, just drag them to the ComfyUI window to open.TL;DR version:Select the gguf files that fit your system.Add the starting image.Update prompt #1 with a description of anything that should remain fixed through the entire video, e.g. "A girl with short blond windswept hair is sitting at a table under a beach umbrella."Update prompt #2 with the individual scenes as "&lt;time&gt;|&lt;action&gt;|&lt;camera movement&gt;, e.g. "4|The girl holds the glass to her mouth and sips slowly from the straw in the orange juice. |The camera remains steady and doesn't move."Then run to get the video built.Camera movement can be holding still, panning, rotating, orbiting, or "Return to original image" to create a relatively seamless loop. Add LoRas for more complex camera movement, or better action adherence in the panels at the far left. Remember to add any LoRa activation keywords to the segments that use it.

Wan 2.2 Long video via multi-step actions

Now optional key frames can be added, and any scene can be selected to end on one of the key frames or the original image.
