LTX2 basic GGUF 720p workflow

GGUF custom node: https://github.com/city96/ComfyUI-GGUF

(Please update your GGUF node and ComfyUI to the latest versions.)

embedding: https://huggingface.co/Kijai/LTXV2_comfy/tree/main/text_encoders

Place the text encoder-related files here: ComfyUI\models\text_encoders

audio vae is here: ComfyUI\models\checkpoints

upscale model is here: ComfyUI\models\latent_upscale_models

Use the distilled model and distilled-embedding, or use the dev model and dev-embedding with distilled-lora.

T2V: set bypass image on

I2V: set bypass image off

You can bypass upscale node for lowres.

Try starting with a lower length (perhaps 9).
