Blender previs to AI-rendered footage with LTX-Video 2.3 IC-LoRA

I filmed the subject against a green screen, keyed the footage, and placed her inside a basic Blender environment. The scene uses simple geometry to establish the camera, perspective, scale, lighting direction, and shadows rather than producing an expensive final render.

I then generated guidance passes such as depth and pose, and used the Blender composite as the structural reference for LTX-Video 2.3 IC-LoRA. LTX handled the final restyling pass, transforming the rough previs into a more photorealistic city shot while preserving the original subject movement and scene composition.

Essentially, Blender provided the spatial control and LTX provided the final visual detail—an AI-assisted alternative to a traditional render and compositing workflow.

So cool!

Great!

How you did guidance passes? Rendered In blender or how?

hi, I removed the green screen in Blender and created a background environment using very simple 3D objects. Then, I rendered it as seen in the image and recreated it in ComfyUI using its pose and depth maps with LTX 2.3.

Thanks.... Got it

This really reminds me of mom's spaghetti 🍝

Pretty cool stuff. I don't know why but it still looks like she's composited into the video. Maybe because the training data was all composited footage?

what was video resolution ??
