LTX2.3 All in one [SFW / NSFW] - LTX Director + ID LoRA + ControlNet + Detailer + Upscaler

Thanks everyone for the Buzz ⚡ and the feedback 😊

This workflow supports 3 types of models currently:

• Standard LTX 2.3 distilled

• LTX 2.3 distilled GGUF

• 10Eros

💡 The models are self-contained. You can safely delete the entire group of whichever model you don't use without breaking the workflow. The remaining model groups will work independently without any additional changes needed.

⚠️ COMFYUI SECURITY ERROR FIX: At the end of this post.

🎬 This is a total revamp of the original workflow with the same features, but using LTX Director.

You can find the author's tutorial here.

This workflow is a modular and flexible text/image/audio-to-video generation system built in ComfyUI, designed to give full control over video creation using LTX-based models. It allows you to easily mix and match multiple generation modes such as text-to-video, image-to-video, lipsync, and fully guided animation by enabling or disabling grouped nodes.

📝 Personal notes:

• The 10Eros model is better for NSFW content, whereas the standard model is better for SFW generations, although the body movement of the 10Eros model can be beneficial in some cases for SFW content too, but in general, use each model as I just said.

• Try to always use 2 phase sampling generations (Half res + 2x upscaler), this yields the best quality and character consistency, LTX is not good at all at preserving character ID, so don't make it worse by doing a single pass generation. The upscaler model adds extra detail and improves character consistency, that's why I recommend using it.
  However, using half res on resolutions under 480p will generate bad quality videos since, at that point, you would be creating a first pass video so small that the upscaler won't have much details to work with. So for 480p and below, one single pass video generation is the way to go. On an RTX 4090, you can generate 1440p short videos using half res + upscaler, however, I think the sweet spot between quality and speed is at 720p.

• Don't use the detailer when generating "Amateur look" videos, it adds a light layer of detail to the final result, and most of the time it will look too "polished" for a real amateur recording; amateur style videos look more real when they look low quality.

Main features

• LTX Director support

• GGUF support

• SFW / NSFW support

• NSFW prompt enhancer

• Text, image, audio, and ControlNet-driven video generation

• LoRA support (character, style, and voice via ID LoRA)

• Custom or AI-generated audio with automatic syncing

• Reference image + unlimited keyframes (FFLF animation control)

• ControlNet video guidance with hybrid reference support

• Half-res sampling + 2× upscaling for faster high-quality results

• LTX detailer for enhanced final output

Common Setups

• Text to video:

  Timeline text segment.

• Image to video:

  Add an image segment to LTX Director, extend it to fill your video duration and input a segment prompt for that segment.

• Lipsync:

  Add an image segment to LTX Director, extend it to fill your video duration, input a segment prompt for that segment and add the audio file to the timeline. Enable custom audio in LTX director.

• Audio to video:

  Add a text segment to LTX Director, extend it to fill your video duration, input a segment prompt for that segment and add the audio file. Enable custom audio in LTX director.

• Character LoRA + voice reference:

  Add a text segment to LTX Director, extend it to fill your video duration and input a segment prompt for that segment. Add your character LoRA to the power LoRA loader, then activate ID LoRA and load a voice reference

• Voice reference to video:

  Add a text segment to LTX Director, extend it to fill your video duration and input a segment prompt for that segment. Activate ID LoRA and load a voice reference

• Character animation:
  Add an image segment to LTX Director, extend it to fill your video duration and input a segment prompt for that segment. Enable controlnet.

• First frame → last frame:
  Add two image segments to LTX Director, and shrink the second image segment (last frame), add your prompt in the first image segment and in the second image prompt write "."

• First → middle → last frame:
  Same thing as for FFLF, but adding an image segment in the middle and its corresponding prompt.

• Character animation with custom voice:
  Image segment + ID LoRA + ControlNet

COMFYUI SECURITY ERROR FIX

If you hit a security level error while trying to install some custom nodes from ComfyUI manager:

1. You need to temporarily change the security level in your config.ini file.

• If you are using the portable version, the file is located at:
  ComfyUI/user/__manager/config.ini

• Change the value to:
  security_level = weak

IMPORTANT:
Do NOT forget to restore it back to its original value, you should restore it afterward for safety reasons.

1. Perform a hard restart of ComfyUI (completely stop it, then start it again).

2. Install the custom node(s) using ComfyUI manager and double-check that it is the official one.

3. Restart ComfyUI and check if the node(s) work(s) properly.

4. Once everything is working properly, restore your original security level in the config.ini file and restart ComfyUI one final time.

Detailed instructions are contained in the workflow itself:

• Red nodes are instructions and useful notes.

• Yellow nodes are configurable elements you can adjust to your needs.
