LTX-2 19B GGUF 12GB ComfyUI Workflows 5 TOTAL! t2v/i2v/v2v/ia2v/ta2v — Text-Audio-2-Video-V2

This ComfyUI workflow generates LTX-2 video from text, images, short video clips, and audio, with modes for text-to-video, image-to-video, video extension, text-and-audio-to-video, and image-and-audio-to-video.

The workflow lists five paths: text-to-video, image-to-video, video-to-video extension, text-and-audio-to-video, and image-and-audio-to-video.

It includes two audio-enhancement nodes near the end of the workflow.

For text-to-video, provide a text prompt; for video extension, provide a few seconds of video and a prompt to continue it.

For audio-driven paths, provide a text prompt and audio, or an image and audio; the image-and-audio path is described as lip-syncing the result.

For the V2 version, update ComfyUI and comfyui-kjnodes because ComfyUI reorganized where the embedding model loads.
