V11 - Updated for compatibility with recent ComfyUI versions (ComfyUI Frontend versions > 1.40.0.x totally borked subgraphs).

V10 - Use with ComfyUI Frontend versions <= 1.40.0.x

This is my take on an "ultimate WAN 2.2 I2V / SVI" workflow.

I can only recommend using this WF if you are also using ComfyUI-Easy-Install. It seems that the some of the very popular "must-have" nodes I've used, which are included in this, may be problematic for users who are NOT using it.

Convenience features:

- Global LoRAs option. Each gen step can have additional LoRAs.

- Global prompt prefix/suffix option. Each gen step can have this customized.

- Each gen step has option to "Save latent" (can be loaded later for SVI extension)

- Color correction option for each gen step

Can independently run I2V or SVI or both

- Starting point for I2V can be First Frame ***or*** FLF2V (first/last) ***or*** FMLF2V (first/middle/last)

- Start point for SVI can be I2V ***or*** load a saved latent ***or*** load a video file

SVI blocks:

- Can have overrides for Shift, Total Steps, Split Step

- Can be duplicated

I also used a few nodes that I like from this node pack:
