This is my very first workflow. It's based on Wan2.2 and can create videos of unlimited length. It generates 5-second videos at a time, but these fit together perfectly. This allows you to build a video piece by piece. If you like a segment, you can keep it and expand upon it. If you don't like it, it's regenerated. All the segments you have can be assembled later.

Furthermore, the workflow is designed for maximum consistency and uses ReActor.

V1.4 is still not perfect, but it works quite well. Since I am currently working on another project, I am making my current version available to you here. It is not quite finished yet, but it produces good results.

Info: The best results when extending videos are obtained by assigning the same seed to all extensions as the original video.

Info: If ComfyUI cannot find the saved latent, you need to adjust the path in the "Latent Save" group.

- fix scale for Video extention

- fix upscale for Endframe in Landscape

- fix bug color correktion without video extention

- some minior fixes and improvements

- removed colorcorrect after decode (not needed, Color Match is much better)

- some little changes in settings

- Videos with more than 81 frames can now be loaded for expansion.

- Color Match sets color now after Decode too, for maximum results.

- add Latent Save after video generation

- add Load latent for video extension with better transitions and prevents plastic look

- add Load and Save with Name

- add automatik save to input folder

- add smooth video extention via prompt shifting

- add face detailer for testing

- add latent noise between sampler for better details and textures.

- add Fast mode switch (Generate 41 frames instead of 81 and interpolate them.)

- experimental Face detailer (can be enabled if needed)

(Due to time constraints, the documentation was not updated.)
