B-Roll Prompt Guide Adds 25 Camera Templates for Video Campaigns
Luma Labs published a guide containing 25 structured B-roll prompts for Dream Machine covering establishing shots, product close-ups, and transition sequences. Editors and commercial producers can use these templates to generate targeted insert shots without wasting generation credits.
Luma Dream Machine, the AI video generation platform from Luma Labs, released an official library of 25 structured B-roll prompts designed for commercial video campaigns. The prompt collection provides specific text recipes for generating insert shots, establishing scenes, and visual transitions. The guide helps editors overcome common prompting failures by detailing exact camera movements, lighting descriptions, and subject positioning optimized for Luma Dream Machine.
What's new
The release categorizes 25 production-oriented prompt formulas into five distinct editorial categories:
- Establishing shots: Prompts tailored for wide exterior angles, architectural sweeps, and atmospheric environment setups.
- Product close-ups: Macro-lens descriptions that focus on material textures, lighting glints, and subtle product motion.
- Tech and atmospheric scenes: Abstract visual layers, futuristic server racks, and ambient background plates for corporate edits.
- Visual transitions and filler shots: Dynamic camera pushes, whip pans, and bokeh defocus elements built to bridge primary scenes.
Each prompt template includes specific keywords for lens focal lengths, lighting setups, and motion descriptors designed to yield stable motion output from Luma Dream Machine without requiring extensive negative prompting.
How it fits your workflow
In video post-production, high-quality insert shots and B-roll dictate the overall pacing of a sequence. Generating filler footage in AI video generators can rapidly consume monthly render credits when unverified prompt phrasing yields unintended spatial warping or erratic camera movements. By using standardized camera vocabulary verified against Luma Dream Machine, editors can generate usable 5-second cutaways for documentaries, commercial spots, and YouTube videos on the first try.
Compared to trial-and-error prompting in competing tools like Runway Gen-3 Alpha or Kling 1.5, Luma's templates prioritize predictable spatial motion. For example, using explicit camera direction terms like "slow tracking dolly shot" or "shallow depth of field macro pull" ensures the Dream Machine engine maintains consistent focus on the intended subject rather than distorting background elements.
What it costs / how to try it
The 25 AI B-roll prompt templates are accessible for free on the official Luma Labs site. Creators can copy and execute these prompts immediately within Luma Dream Machine using standard account tiers, which offer free generations along with paid monthly subscriptions for higher concurrency and faster rendering.
