LTX2.3 All in one - ID LoRA + ControlNet + Detailer + Upscaler + Custom Audio + Keyframes

⚠️ If you see this workflow as updated, nothing has changed, I had to re-upload the file because the site has been broken lately...

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 switch between multiple generation modes—such as text-to-video, image-to-video, lipsync, and fully guided animation—by enabling or disabling grouped nodes.

The pipeline supports advanced features including LoRA-based character and style conditioning, voice identity transfer (ID LoRA), custom or generated audio, and ControlNet-guided animation using reference videos. Users can also incorporate keyframe images for structured motion control or rely on a single reference image for consistent character appearance.

Performance and quality can be balanced through options like half-resolution sampling with 2× upscaling, as well as post-processing tools like the LTX detailer.

Main features

• Modular, toggle-based workflow (quickly switch modes)

• 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 images + up to 4 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
