Every seat is the front row.
How to plan IMAG and big screens for a festival stage, from the VJ for Daft Punk's 2006 Coachella set: box lenses, IMAG vs livestream cuts, delay, lumens, LED nits and pixel pitch.
Key takeaways
- Plan the canvas from the sightlines: left and right IMAG, a center wall, or one wide surface. Get the artist rider early.
- The money shot comes from front of house, 150 to 300 feet out: long box lenses (about 80x to 100x) on a platform that will not shake.
- The crowd already has the wide shot. Keep IMAG tight and give the livestream its own cut with wides and scale.
- Keep camera-to-wall delay to about 1 to 2 frames; every extra scaler or frame sync adds delay.
- Projector lumens = screen area (sq ft) x target foot-lamberts / screen gain. 900 sq ft at 50 fL is about 45,000 lumens.
- Daylight needs LED at 5,000+ nits; dim to roughly 10 to 30% after dark. Pixel pitch: about 1 meter back per millimeter.
- Give the director clean comms to every operator, coordinate wireless early, and make "hold a wide, safe shot" the fallback.

At a festival, most of the crowd never sees the artist's face up close. They see the screens. IMAG, short for image magnification, is how 100,000 people get the front row. I was the VJ for Daft Punk's pyramid set at Coachella in 2006, and I was also the VJ for Rabbit in the Moon at events like EDC. Here's how to plan it so it holds up, day and night. Start with sight lines, not gear. Walk the field from the back and from the sides.
Where will the farthest fans stand and how big does a face need to be for them to read it? Then, define the canvas. Left and right IMAG screens, a center wall for visuals, or one wide surface the media server splits up. Get the artist's rider early. Some acts want IMAG on every song. Some want only their own content, and some want none at all. When I VJ'd for Rabbit in the Moon, the video wasn't decoration. It was part of the performance, cued to the music like another instrument.
Acts like that need the screens planned around their show, not the other way around. Next, the cameras. Your money shot usually comes from front of house, which can be 150 to 300 feet from the stage. That means long box lenses, around 80 to 100 times zoom on a solid platform that won't shake when the base hits. Add handheld cameras on stage with wide lenses for energy, a jib or crane for sweeping crowd shots, and small robotic cameras on the DJ booth or the drum riser.
At Daft Punk's Coachella set, the tent was packed far past capacity. For most of that crowd, the screens were the show. One more thing. The screens and the live stream need different cuts. The crowd in the field already has the wide shot, they're standing in it. So the IMAG stays tight on faces, hands, and the moments they can't see from the back. The audience at home needs the opposite, wides, the crowd, the scale of the place.
Plan a separate program feed for each, even when it's the same cameras. Watch your delay. If the screen runs more than a couple of frames behind the performer, the people near the stage see lips out of sync with the sound. Keep the signal chain short. Camera, switcher, media server, LED processor. Every extra scalar or frame sync adds delay. And plan the long runs early. At Coachella, I was the first one allowed to trench fiber across the polo field, so live video could reach the far end of the grounds.
Test it at sound check. Have someone clap on stage and watch the wall. Then decide how the picture reaches the audience. Projection can look beautiful after dark, but brightness is everything. A rough rule. Multiply the screen area in square feet by the brightness you want in foot Lamberts. A 40-foot wide screen is about 900 square feet. At 50 foot Lamberts, that's around 45,000 lumens. Usually two or more projectors stacked and aligned.
In daylight, projection simply washes out. For a daytime set, you need LED. Outdoor panels run 5,000 nits or more to compete with direct sun. After dark, dim them way down or you'll blind the crowd and blow out your own cameras. Choose the pixel pitch by viewing distance. A rough rule is 1 meter back for every millimeter of pitch. Coms tie it all together. The director needs a clean channel to every camera operator, plus separate channels for the VJ, the LED tech, and stage management.
Festival radio frequencies are crowded, so coordinate your wireless with the production office before you arrive. And give every operator a fallback. If coms drop, hold a wide, safe shot until the director is back. Plan the canvas, pick the right glass, keep the delay low, match your brightness to the sun, and keep everyone talking. Do that, and the back row feels like the front row. I'm Lucky. If you're planning a stage, a festival, or a live event, let's talk about how to make every seat a great one.
