Endless Wan 2.2 I2V (SVI 2 Pro)
A simple workflow to create Wan 2.2 videos of unlimited duration, using SVI 2.0 Pro.
The workflow has a 5 sec "Initial" block and 8 more optional "Extend" blocks of 5 sec each that can create almost 45 sec of video (some frames are lost in the connection).
Every block has its own Prompt and Length control in seconds (don't use more than 5.0).
If more seconds are needed, you can copy an "Extend" block, connect it with the others and continue..
Each block has a fix noise seed number that let you experiment with a block without re-generate all the previous, already generated blocks.
There are 2 LoRA sections. The Main and the Extra (for High and Low models).
All blocks are using the Main section, but you can choose if a block will use the Extra LoRAs or not.
GGUF loaders for low VRAM systems with lightx2v 4-step LoRA.

Bernini at 24fps with svi 2 pro would be awesome.
Call me an idiot, but i cant find where to add the prompt.
Hi, you will put the first description in the "initial" block. That describes the first five seconds. For each additional "Extend" block, you will put the description at the bottom of those that you activate. So you control each blocks action.

@Cyphermodx - when you open the workflow none of the text boxes work. They're not.. active.. not there. If you then go into the sub-graph and "open" or "unhide" the text encoder node, and then go back to main workflow page, then the text box is there. I tested with several and I had to do this for each new segment I enabled. I have no clue why and only discovered it by accident.
@Symbiot78 I hate when workflow designers collapse major nodes that you need to modify form time to time or all the time. Such as upscale nodes, like, people's directories are different so we'll need to change that... don't hide them behind other nodes and pin everything in place. I just delete the workflow when I see a bunch of pinned nodes.
@Symbiot78 Apologies, I haven't used this workflow, I was just going by the image of the workflow and trying to help as I was checking out what was new for the day.
The workflow should look like in the screenshot.
There, you can see that every section has a prompt.
If it's not like the screenshot, that means that you are using a more current, but unfortunately broken version of comfyui-frontend..
You can search google for the subgraph issues with the 1.4x.xx releases of their frontend.
The last frontend version, that the subgraphs were working OK for me, was 1.39.2.
To install this version, you must do pip install comfyui-frontend-package==1.39.2 in your ..\venv\Scripts\ folder.
After that you will see a warning once, but other than that, everything will work fine..
@Symbiot78 There is a "Extend Video Duration" node that you can use to enable the blocks you need.
And I thought it was the crazy
