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 both 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.

Version 2.0

This version adds a second Extra LoRA section so now there are 3 LoRA sections.

The Main, the Extra 1 and the Extra 2 (for High and Low models).

All blocks are using the Main section, but we can choose if a block will also use one of the Extra LoRAs or not.

Warning: The two LoRAs already loaded in the Main LoRA section are mandatory (for 4-steps & Linked blocks)
