48 Hours at ETH Denver: How We Captured the Crosschain Collider

ETH Denver is controlled chaos. Thousands of builders crammed into a convention center, half of them running on three hours of sleep and sheer conviction that whatever they're building is going to change everything. My job was to walk into that energy and come out the other side with a film that actually captures it.

Here's how we did it for Arbitrum's Crosschain Collider showcase — from load-in to final export.

The Brief

Arbitrum needed more than a highlight reel. They wanted a film that communicated the scale of their Crosschain Collider activation while feeling authentic to the builder culture of ETH Denver. Not corporate. Not sterile. Real.

The deliverable: a polished recap film, plus social cuts for post-event distribution. The timeline: two days of shooting, one week to deliver. No pressure.

Gear and Setup

For events like this, I travel light but deliberate. Here's what I packed:

• Sony FX6 as the A-cam — reliable low-light performance is non-negotiable when you're shooting in convention halls with questionable lighting
• Sony A7S III as the B-cam for run-and-gun moments, crowd shots, and b-roll
• DJI RS3 Pro gimbal — smooth motion through crowded spaces without a Steadicam rig
• Sennheiser MKE 600 shotgun mic plus wireless lavs for keynote speakers
• Portable LED panels for any sit-down interviews we could grab between sessions

The key with event gear is versatility. You don't get second takes. When a speaker drops something profound on stage, you either caught it or you didn't.

Day One: Setting the Scene

We arrived at the venue at 6 AM for load-in. The first few hours of any event shoot are about establishing shots — the space before people fill it, the signage going up, the tech checks happening in the background. This footage is invisible to most viewers, but it's what gives the final film a sense of place and progression.

By 10 AM, the doors opened and the energy shifted completely. Developer workshops were running simultaneously across multiple rooms. Keynote speakers were doing sound checks. The Arbitrum team was making last-minute adjustments to their booth setup.

I split my focus: gimbal work through the main floor to capture the scale, then locked-off shots of individual sessions to get usable audio. The biggest challenge at ETH Denver is noise. There's always music bleeding from somewhere, conversations overlapping, and the constant hum of a building packed past comfortable capacity.

Day Two: The Main Event

Day two was the Crosschain Collider itself. This is where the energy peaked — live demos, panel discussions, and the kind of spontaneous conversations that only happen when you put a thousand builders in one room.

I shifted my approach from documentary-style coverage to more intentional storytelling. Instead of trying to capture everything, I focused on moments: a developer's face when their demo worked perfectly, the crowd reaction to a keynote announcement, the quieter conversations happening in the corners of the venue.

The best footage from any event isn't the stage — it's the margins. The handshake after a panel. The whiteboard sketch during a coffee break. The group huddled around a laptop at 11 PM. That's where the real story lives.

The Edit

Back in the studio, I had roughly 14 hours of raw footage to cut down into a three-minute film. The editing process for event content is as much about restraint as it is about creativity.

My workflow:

1. Selects pass — scrub everything, flag the moments that made me feel something
2. Audio-first assembly — lay down the keynote audio and ambient sound to establish pacing
3. Visual layering — match visuals to the emotional arc, not just the chronological timeline
4. Color grade — match the moody, high-contrast look that fits both the Arbitrum brand and the ETH Denver atmosphere
5. Sound design — subtle bass hits on transitions, room tone to maintain presence

The final film tells a story in three acts: anticipation (setup and arrival), energy (the event at full tilt), and reflection (the quieter moments that give it meaning). You can watch the full Crosschain Collider film here.

What I Learned (Again)

Every event reinforces the same lessons:

Move fast, but don't rush. There's a difference. Moving fast means being ready when the moment happens. Rushing means missing it because you were already chasing the next one.

Relationships matter more than gear. The Arbitrum team trusted me to be in the room during their private planning sessions. That access — which you only get through trust built over multiple projects — is what separates a good event film from a forgettable one.

Shoot for the edit, not for the moment. It's tempting to chase every exciting thing happening at a conference. But if you don't have a narrative structure in mind while you're shooting, you'll end up with 20 hours of footage and no story.

The Takeaway

Event videography at this level isn't about showing up with a camera. It's about understanding the client's goals, the audience's expectations, and the story that connects the two. Arbitrum didn't need a video that said "we were at ETH Denver." They needed one that said "this is what happens when builders come together."

That's the difference between documentation and filmmaking. And it's why I keep coming back to events like this — because the energy is real, the stakes are high, and the stories are worth telling.
