Summary

This free AI b roll generator turns a short world description into a numbered shot list for your next trailer or devlog. Pick a mood, pick a shot count, and it builds ten camera-ready prompts, establishing wides, texture inserts, silhouettes, weather passes, each one written for Seedance, Runway, Pika, or any AI video model. No signup. No video is generated on this page, you get the plan, then you render the footage yourself.

Each shot below ships with a full, ready-to-paste prompt for your video generator of choice.

How the generator works

What goes into every shot list

Ten shot archetypes

Every list draws from ten proven b-roll archetypes: establishing wides, texture inserts, silhouettes, weather passes, transitions. The same rotation editors reach for when cutting a trailer. You are not guessing at shot types, you are picking from the set that already works.

Mood sets the lighting

Pick moody noir, epic cinematic, or three other moods. Each one rewrites the lighting and color language baked into every prompt, so the shots actually match your world's tone instead of looking like generic stock footage bolted onto a fantasy map.

Prompts you can paste

Every shot ships as a complete prompt for Seedance, Runway, Pika, or whichever AI video model renders your footage. Copy, paste, generate. No prompt engineering required, the phrasing and camera language are already built in.

From shot list to finished trailer

You already did the hard part when you generated a playable world. This tool closes the gap between that world and a trailer someone actually watches. Describe the scene, pick a mood, and paste each prompt into your video model of choice. Cut the results together and you have b-roll that matches the world you built, not stock footage that almost matches it. Most devlogs die at this exact step, the world is done but the footage to show it off never gets made.

  • Describe the world or scene once
  • Pick a mood and a shot count
  • Copy each prompt into your AI video tool
  • Render, then cut the shots into your trailer or devlog

Common questions

Does this generate actual video?
No. This is a planning tool. It turns your world description into a shot list and matching prompts. Paste those prompts into a video model like Seedance, Runway, or Pika to render the footage.
Is it free?
Yes. No signup, no limit on how many times you regenerate. The shot list updates the moment you change the description, mood, or shot count.
Where do the shot types come from?
Ten archetypes used constantly in game trailers and devlogs: establishing wides, texture inserts, silhouettes, weather passes, transitions, and more. Cut a few trailers and the same six or eight shots keep doing most of the work.
Does it work for any game engine, not just AuxWorld worlds?
Yes. Describe any scene, biome, or environment, indie, Unity, Unreal, or a world you forked in AuxWorld. The prompt builder does not care where the footage comes from.
Is my world description stored anywhere?
No. Everything runs in your browser. Nothing is sent to a server, except the anonymous tool-run beacon used to measure how many people use the page.
Can I get more than 10 shots?
Run it twice with two different moods. A noir pass and a cozy pass on the same world description gives you 20 distinct shots for a longer cut.
Which AI video tool should I paste these prompts into?
Whichever one you already use. The prompts are written model-agnostic, so they work with Seedance, Runway, Pika, or Veo without edits.
Do I need editing experience to use the output?
No. Each shot already tells you the framing and the camera move, plus the exact prompt. You render the clips, drop them on a timeline in whatever order makes sense, and cut to the beat of your voiceover or music.

Your world already has the footage

AuxWorld turns a prompt into a playable world in about 30 seconds. Generate one, point the shot list at it, and you are already rolling.
