Automated brand-styled video b-roll using LTX-Video and a custom LoRA

A streaming media brand needed cinematic b-roll generated automatically from editorial scripts, matching a specific visual identity. We built an LTX-Video pipeline with a custom brand LoRA and a render queue.

Problem

What they were stuck on

The client's editorial team was waiting 2–3 days for outsourced b-roll. Stock footage didn't match their visual identity, and bespoke commissions blew their per-segment budget. They needed b-roll generated in minutes, on-brand, and triggered automatically when an editor uploaded a script.

Approach

How we built it

STEP 01

Model selection

Benchmarked LTX-Video 2.2, Wan 2.1, HunyuanVideo, and Mochi-1 on the client's reference shots. LTX-Video won on cinematic motion and render-time ratio.

STEP 02

Brand LoRA

Trained a style LoRA on 1,800 frames of the client's existing footage - colour grade, framing, depth of field. Applied at inference for consistent brand look.

STEP 03

Script → shotlist

An LLM step converts the editor's script into a shotlist (subject, camera move, mood, duration). Each shot becomes a prompt + LoRA call.

STEP 04

Render queue

Redis-backed job queue distributing generation across a multi-GPU node. Adaptive batching, automatic retries, and a preview-then-approve flow for the editor.

STEP 05

Delivery

Generated MP4s pushed straight into the client's NLE bin via API. Versioned, with prompt metadata embedded for reproducibility.

Our editors now sketch a script and have a first-pass cut ready by lunch. The brand look is consistent because the LoRA learned it.
