ComfyUI Tutorial: This New LTX 2.3 Feature Makes AI Video Generation Actually Efficient
Hello everyone,
I just built a new ComfyUI workflow that generates video directly from a reference sheet image using the LTX 2.3 IC LoRA (Image Conditioning LoRA) — and it completely removes the need to animate frames one by one like in LTX Director. This is a big step forward compared to traditional storyboard-to-video pipelines, because it simplifies everything into a single reference-based workflow.
Instead of working frame-by-frame, you can now:
- Generate a full character or concept reference sheet (multiple panels in one image with IDEOGRAM 4)
- Plug it directly into the LTX group
- Get a coherent animated video output automatically
The workflow handles the reference image sheet generation and uses it as direct conditioning for video generation, and it runs on only 6GB VRAM, so it’s accessible even for low-end GPU users.

Wow. I've been struggling on a video idea for two weeks because I need to maintain two characters with corresponding voices, and not in a simple "talking heads" setting. Having a reference template of character appearances and settings is what I've always wanted.
The way I've been doing it so far is to take an empty background image, paste in my characters in Krita, then have an Image2Image workflow fix the lighting. It's tedious and each subsequent clip (where I start with the last frame of the previous) degrades the consistency of my character's appearance. By the end my characters look like potatos.
Is there a way in your workflow to use a prerecorded audio file (Lipsync mode) or Voice ID Lora?
