    V2.6 LTX-2.3 DEV & Distilled Video with Audio + LTX Director workflow

    Minor update to LTX2.3 Image to Video with Ollama workflow:

    • sampling Preview implemented

    • NAG to allow negative prompt for Distilled model (CFG=1)

    Included a Workflow supporting LTX Director node, which is awesome, it supports:

    • First, Mid, Last or whatever frame, basically any frame is a keyframe

    • Prompt Relay which allows to generate frames prior to Input Image

    • more precise editing: What shall happen when in the clip?

    • Audio Import to create lipsynced clips

    • Image or Text to Video, even both in one process

    more Info: https://github.com/WhatDreamsCost/WhatDreamsCost-ComfyUI

    recommend to watch the creatorΒ΄s youtube video in above link for how to.

    => added a longer example video at the end.


    V2.5 LTX-2.3 DEV & Distilled Video with Audio

    Image to Video and a Text to Video workflow, both can use own Prompts or Ollama generated/enhanced prompts.

    • works with latest LTX 2.3 Distilled model (8 steps, CFG=1) or Dev model (20 steps, CFG=3)

    • Updated the processing for DISTILLED and DEV model, select the DIST or DEV model in loader node and switch to dedicated DIST or DEV processing pipeline, so each model has its own processing.

      • DIST model pipeline: Standard Guider and Basic Scheduler, follows the manual sigmas issued by Lightricks

      • DEV model pipeline: MultiModal Guider and LTX Scheduler + Distilled Lora on latent upscaler

    • Included a workflow version with "RTX Video Super Resolution" node, which upscales videos in highspeed.

    Tip: With latest Comfy and LTX updates, the processing got faster for me, so I can increase the scale_by in sampler node from 0.5 to 0.6 or higher to have crisper videos with minor impact on render time.


    V2.3 LTX-2.3 DEV & Distilled Video with Audio

    Downloads for LTX 2.3:

    update : April 14th 2026 : Lightricks has updated their LTX 2.3 distilled model to 1.1 (and Lora):


    smaller LTX 2.3 GGUF Dev or Dist. models work as well. (replace Checkpoint loader node with Unet loader node from this custom node: https://github.com/city96/ComfyUI-GGUF ):


    V1.5 LTX-2 DEV Video with Audio including latest πŸ…›πŸ…£πŸ…§ Multimodal Guider

    Image to Video and a Text to Video workflow, both can use own Prompts or Ollama generated/enhanced prompts.

    Replaced the Guider node with latest Multimodal Guider node, see more details in WF notes or here: https://ltx.io/model/model-blog/ltx-2-better-control-for-real-workflows Before we had 1 CFG parameter for audio and video. With multimodal guider, we now can tweak audio and video seperately with even more parameters...


    V1.0 LTX-2 DEV Video with Audio:

    Image to Video and a Text to Video workflow with own Prompts or Ollama generated/enhanced prompts.

    • setup for the LTX2 Dev model.

    • uses Detailer Lora for better quality and LTX tiled VAE to avoid OOM and visual grids

    • 2 pass rendering (motion+upscale). Upscale process uses distilled and spatial upscale Lora

    • setup with latest LTXVNormalizingSampler to increase video & audio quality.

    • Text to Video can use dynamic prompts with wildcards.

    Quick question: do I need to have Ollama running if I wanna use your workflow?

    No, there is a switch to toggle ollama off, so you can use your own prompt. If you have no ollama installed, comfy might post a message, but supposed to work anyway. Or delete the 2-3 dedicated ollama nodes from Workflow.

    @tremolo28Β Well, i do have Ollama, but I'm quite new at this.... I think I'm supposed to enter an IP address inside the comfyui-ollama node?

    @artificialotakuΒ within the green node "Ollama Connectivity", hit the "reconnect" button, then select the ollama model in the drop down field below the URL field, ollama needs to run in the back (in your tray, if you are on windows).

    Have added a short Ollama help section at the end of the description.

    @tremolo28Β Just saw that new section, thanks, i think everything is clear now, will give it a try!

    Hi, thanks for the workflow, this workflow works great. I was wondering if you could add 1st and last frame to this I2V workflow ?

    VAELoaderKJ just complains checkpoint does not contain valid VAE even though I have selected the LTX23_audio_vae_bf16

    Hi, make sure to update KJnodes custom nodes. The VAE loader requires the latest update.
