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

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.

V1.5 LTX-2 DEV Video with Audio including latest π π £π § 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...
added a Power Lora Loader node to inject further Loras
use Image to Video Adapter Lora to improve motion for I2V: https://huggingface.co/MachineDelusions/LTX-2_Image2Video_Adapter_LoRa/tree/main
replaced a node to no longer require comfymath custom nodes
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.

Ollama help:
Install Ollama from https://ollama.com/
download a model: Go to a model page, chose a model , then hit the copy button, i.e. https://ollama.com/huihui_ai/qwen3-vl-abliterated
open terminal and paste the model name, i.e.: ollama run huihui_ai/qwen3-vl-abliterated
model will be downloaded and can be selected in green comfy node "Ollama Connectivity". Hit "Reconnect" to refresh.

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!
Thank you for your work.
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.
