A GGUF version of the Image to Video workflow of the newest LTX Video version 2.3 in subversion 1.1.
Runtime profile
Source description
A GGUF version of the Image to Video workflow of the newest LTX Video version 2.3 in subversion 1.1.
Howto
Drag an image into the image nodes, adjust the prompt, and press queue. The rest should fit.
Description
An image to video ComfyUI workflow with LTX Video 2.3 subversion 1.1. The nodes are wired and visible in the traditional way and grouped together. No set and get nodes, no subgraph. I like it simple. It produces two videos, one with audio, one without.
Time
The example video in a resolution of 1024 x 576 was generated in 240 seconds at Windows 11 at an AMD Radeon AI PRO R9700. I have yet to test it on Linux, which is usually faster by a third.
AI-generated commentary
AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.
Use this ComfyUI image-to-video workflow to turn an image and a prompt into two videos: one with audio and one without. It is a GGUF workflow for LTX Video 2.3 version 1.1.
The nodes are wired and visible in grouped sections, with no set/get nodes or subgraph.
Drag an image into the image nodes, adjust the prompt, and press queue.
Suggestion · not verified
The outputs are two videos: one includes audio and the other does not.
Use it in ComfyUI with the LTXV 2.3 base model.
The workflow was generated with 32 GB of VRAM and includes a ram saver node that you can enable.
Listed model files include: gemma_3_12B_it_fp8_scaled.safetensors, ltx-2-19b-distilled-lora-384.safetensors, ltx-2-spatial-upscaler-x2-1.0.safetensors, ltx-2.3-22b-distilled-1.1-Q5_K_M.gguf, and ltx-2.3-22b-distilled-lora-dynamic_fro09_avg_rank_105_bf16.safetensors.
Additional listed model files are: ltx-2.3-spatial-upscaler-x2-1.1.safetensors, LTX23_audio_vae_bf16.safetensors, taeltx2_3.safetensors, LTX23_video_vae_bf16.safetensors, and ltx-2.3_text_projection_bf16.safetensors.
Listed node packs are: comfyui-custom-scripts, ComfyUI-GGUF, comfyui-kjnodes, comfyui-videohelpersuite, and rgthree-comfy.
If you need to try a lower-memory setup, enable the ram saver node before queueing.
Suggestion · not verified
The example video uses 1024 × 576 resolution.
Before use, verify that every listed model file and node pack is available in your ComfyUI setup.
Suggestion · not verified
VAE decoding is described as a bottleneck that froze the author's rig, and Linux use has not been tested.

Requirements
This workflow was generated with 32 gb vram. There is a ram saver node involved, which you can turn on. So you should be able to go lower. The bottleneck that even made my rig freeze is the VAE decode.
Estimated VRAM requirement
Estimate unavailable
12.3 GB across 1 of 10 model files. Model file total + 25% loading overhead + 2 GB execution buffer, rounded up.
