NEW ALL-IN-ONE VIDEO TIMELINE EDITOR FOR LTX-2.3!

EDIT 15 june 2026: right now the ltx node ComfyUI-LTXVideo doesn't work well with the newest comfyui updates. IF YOU HAVE ISSUES, you can use the new FIX-LTXVIDEO-KORNIA.bat file and put it in your ComfyUI_windows_portable folder, next to your run_nvidia_gpu.bat file, run it and it should fix the issues with the node at least until the node receives an update.


Hey everyone! I’ve just released a brand new video on the NEW AI VIDEO TIMELINE EDITOR for LTX-2.3, called LTX Director. This is an amazing new addition for AI video generation that basically gives you a full timeline editor directly inside ComfyUI.

You can now control prompts across your video, use multiple frames, create transitions, add custom audio, and direct your generations way more easily than before, all inside one powerful timeline.

So if you wanted more control over your AI videos, this is really one of the best updates we’ve had for LTX-2.3 so far.

The installer of course automates the entire install process for comfyUI and the models downloads!

LOCAL INSTALL!!! RECOMMENDED TO START FROM SCRATCH

Download the LTX-2-3-ULTRA-COMFYUI-MANAGER_AUTO_INSTALL-V2.bat

Run the bat file

Wait for the install to finish

The webui will launch, load the LTX-2-3_ULTRA_WORKFLOW-V2.json file and there you go😎

DON'T FORGET TO GO UPDATE COMFYUI BY GOING INSIDE THE UPDATE FOLDER AND RUNNING THE COMFYUI UPDATE BAT FILE THEN CHOOSING THE CORRECT LAUNCHER FOR YOUR GPU!!

IF YOU ALREADY HAVE COMFYUI INSTALLED USING A PREVIOUS INSTALLER:

Download the LTX-2-3-MODELS-NODES_INSTALL-V2.bat and place it in the ComfyUI_windows_portable\ComfyUI folder

Run the bat file

Wait for the install to finish

???

Profit 😎

IF YOU GET AN ERROR WHEN LAUNCHING COMFYUI AFTER USING THIS INSTALLER SAYING "AssertionError: Torch not compiled with CUDA enabled" it's ok don't panic.

Just go inside the python embedded folder, click on the folder path, type cmd press enter, this will bring the command prompt window and there type:

python.exe -m pip uninstall torch

python.exe -s -m pip install --upgrade torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu128

--->replace cu128 by your cuda version (if you don't know your cuda version just open a new cmd window and type nvcc --version it will then tell you at the end Cuda compilation tools, release 12.8, V12.8.93 or something different like 12.6, in that case just use cu126 instead of cu128)


IF YOU ARE USING RUNPOD:

Create an account if you haven't already: Runpod

Click on Pod (on the left side) then click deploy

Choose a GPU with at least 24gb of VRAM (4090 is best), click here for the comfyui template (aitrepreneur/comfyui), then edit the template and choose 100gb for both the container and volume disk, then deploy on demand

Go to my pods, wait for everything to finish and then click "connect", then "Connect to HTTP SERVICE port 3000" and click on the manager to update comfyui and restart it

Then go to the port 8888, go inside the comfyui folder and then drag and drop the LTX-2-3-AUTO_INSTALL-RUNPOD-V2.sh file on the left side of the UI then click on the "Terminal" icon on the right side on the UI

Copy and paste these two lines then press enter:

chmod +x LTX-2-3-AUTO_INSTALL-RUNPOD-V2.sh

./LTX-2-3-AUTO_INSTALL-RUNPOD-V2.sh

Wait for everything to be installed

Go back to the port 3000 and click on the manager and restart it

Load the LTX-2-3_ULTRA_WORKFLOW-V2.json file and there you go😎

Also use the command:

tail -f comfyui.log

inside the workspace/logs to get the real time logs so that you always know when the install is done. It will then ask you to restart, so click on that restart button, wait for the webui to reboot, click refresh once it's done and there you go.


IF YOU GET OOM error :

Click on the little 3 dots button, arguments variables then enter

EXTRA_ARGS --reserve-vram 10 --cache-none

then restart the pod
