Version 3.0 has been updated to use LTX 2.3

LTX 2.3 should provide some enhancements such as sharper video

Better audio

Etc..

The normal models are HUGE, can't be used by most people.

This workflow used GGUF for model and text endcocder, gemma.

Trying to keep footprint small, but its getting hard to do.
