This is same as default WF in ComfyUI, but it uses GGUF custom node. Basically, you can insert images, audio, and video into any frame, so anything is possible.T2V, S2V, V2V, I2V First, last, middle frame.voice clone: You can input a few seconds of audio, and then crop those same few seconds after the process is complete.reference image: input a starting image and then instruct it to perform a completely different action. (However, the character descriptions remain the same.) Yes, this is what's called a failed I2V. Again, crop the initial image.extend video: input the images and audio extracted from the video. It will be extended for the remaining length.GGUF custom node: <a target="_blank" rel="ugc" href="https://github.com/city96/ComfyUI-GGUF">https://github.com/city96/ComfyUI-GGUF</a>(Please update your GGUF node and ComfyUI to the latest versions.)LTX2.3 and other: <a target="_blank" rel="ugc" href="https://huggingface.co/unsloth/LTX-2.3-GGUF/tree/main">https://huggingface.co/unsloth/LTX-2.3-GGUF/tree/main</a>orLTX2.3 GGUF: <a target="_blank" rel="ugc" href="https://huggingface.co/QuantStack/LTX-2.3-GGUF/tree/main/LTX-2.3-distilled">https://huggingface.co/QuantStack/LTX-2.3-GGUF/tree/main/LTX-2.3-distilled</a>VAE: <a target="_blank" rel="ugc" href="https://huggingface.co/Kijai/LTX2.3_comfy/tree/main/vae">https://huggingface.co/Kijai/LTX2.3_comfy/tree/main/vae</a>upscale model: <a target="_blank" rel="ugc" href="https://huggingface.co/Lightricks/LTX-2.3/tree/main">https://huggingface.co/Lightricks/LTX-2.3/tree/main</a>text encoder:gemma3 GGUF: <a target="_blank" rel="ugc" href="https://huggingface.co/unsloth/gemma-3-12b-it-GGUF/tree/main">https://huggingface.co/unsloth/gemma-3-12b-it-GGUF/tree/main</a>embedding: <a target="_blank" rel="ugc" href="https://huggingface.co/Kijai/LTX2.3_comfy/tree/main/text_encoders">https://huggingface.co/Kijai/LTX2.3_comfy/tree/main/text_encoders</a>Place the text encoder-related files here: ComfyUI\models\text_encodersaudio vae is here: ComfyUI\models\checkpointsupscale model is here: ComfyUI\models\latent_upscale_modelsUse the distilled model and distilled-embedding, or use the dev model and dev-embedding with distilled-lora.T2V: set bypass image onI2V: set bypass image offYou can bypass upscale node for lowres.Try starting with a lower length (perhaps 9).
