Set extension & world
Multiply a crowd in your footage
Hiring a thousand extras isn't in anyone's budget, but a packed scene sells scale like nothing else. vfxmagia multiplies the people you do have — turning a few extras into a roaring stadium, a marching army, or a teeming street — matched to your footage's perspective and light. It's a tilt-and-fill crowd without a casting call.
Why it works
What you get
- Turn a few extras into a packed crowd or army.
- Fill stadiums, streets, and battlefields with believable people.
- Matched perspective and lighting for a seamless blend.
- Iterate the density and arrangement across renders.
How it works
Three steps
- 01Upload the footage with your real extras in footage mode.
- 02Open the Set extension / scale template and describe the crowd to fill in.
- 03Render, review the crowd blend, then download or refine.
Get started
A prompt to start from
“Extend the small group of soldiers into a vast marching army filling the valley to the horizon, ranks of figures matched to the perspective and overcast light of the original footage, dust rising over the column. Epic, cinematic, seamless.”
Prompt pack
Prompts to copy for each kind of shot
Stadium stands
“Fill the empty stadium stands behind the athlete with a packed, cheering crowd: rows of fans in team colors on their feet, waving scarves and flags, matched to the stadium's floodlight direction and the camera's perspective.”
For sports scenes shot in an empty or half-empty venue. Name the team colors so the crowd looks like one fanbase.
Marching army
“Extend the small group of soldiers into a vast army marching down the valley road: disciplined ranks stretching to the horizon, banners above the column, dust rising under their feet, matched to the overcast light of the footage.”
For period or fantasy battle scenes. Shoot your real extras in formation near camera and let the prompt fill the distance.
Busy city street
“Turn the quiet street into a busy downtown sidewalk at rush hour: pedestrians walking in both directions, people crossing at the lights, commuters with bags and coffee, all matched to the afternoon sun and the camera's eye level.”
For establishing shots that feel empty. Ask for movement in both directions so the crowd does not march in one stream.
Concert crowd
“Multiply the handful of fans in front of the stage into a dense concert crowd: raised hands and phone screens, silhouettes backlit by the stage lights, the crowd swaying to the music as far back as the camera can see.”
For music-video and live-event shots. Backlit silhouettes hide detail and blend well.
Before you upload
Shot checklist
- Shoot a locked-off camera or a slow, steady move. Fast handheld motion makes the added crowd harder to match.
- Place your real extras nearest the camera; generated people work best filling the middle and far distance.
- Leave the area you want filled clear and visible in the frame: stands, road, or open ground.
- Note the light direction and time of day in the prompt so the crowd's shadows match your plate.
- Say how dense the crowd should be and which way people are moving.
