LTX 2.3 - Improved AI Videos & Extensions in ComfyUI!

LTX 2.3 has a bunch of updated version 1.1 model files now available. They boast better audio quality and a different aesthetic experience. You can use these at home, on your OWN COMPUTER - nicely avoiding those nasty privacy and cost issues when using on-line services to make AI videos. Also, because my LTX 2.3 workflow isn't large enough yet, I figured I'd extend it with some groups for... video extensions! Thus, in this video you'll not only learn how to get the very latest and greatest LTX 2.3 models, but also how to extend any generated or existing videos using ComfyUI with a single node! Model sizes range from 8GB to over 40GB, so there's something for everyone! Using this POWERFUL workflow, at the flip of a switch you can now access and combine all sorts of features in a single workflow, including: VRAM Saver Text to video Image to Video Custom Audio Union Control Net LoRAs First Image / Last Image Best Face Swap Generated Video Extension Existing Video Extension All with the very latest LTX 2.3 version 1.1! :) This video is part of an LTX tutorial series and focuses on the Video Extension groups and new models.
