Understory: how we built a 30-second ad entirely inside Runway

A cinematic spot for a fictional brand, produced without leaving the platform. Script, keyframes, animation, voice, music and edit.

By Camilo Cuadra Sieveking · CCS Media, Santiago, Chile · August 2026

The idea

It started with a simple, absurd brief: make an ad for Understory, an adaptogenic mushroom tea brand nobody asked for and probably nobody wants. The product promised mental clarity. The problem was that it tasted awful.

That was the joke.

The concept: treat the suffering of drinking this tea with the same epic solemnity Tibetan monks bring to the search for enlightenment. Himalayan blizzards. Frozen waterfalls. A guru in a cave. And a grimace so honest it needs no words.

The script

Before generating a single frame, we wrote the narrative arc in five beats.

ShotDescriptionVoiceover
1Monk meditating under a frozen waterfall"For centuries... mankind has sought the path to clarity."
2Pilgrim crossing a Himalayan blizzard"Through blizzard. Through darkness. Through suffering so profound... it could only mean something."
3Guru in a cave with the steaming tea"They were right about the suffering."
4Extreme close-up of the grimacetotal silence
5Product shot, the tin rotating"Suffering now comes in a tin. Understory. Tastes like misery. Brings clarity."

The most important decision was the silence in Shot 4. No music, no voiceover, nothing. Just the grimace. That's where all the comedy lives.

The keyframes

Before animating, we generated a reference image for every shot. That let us control exactly how each scene would look before committing credits to video.

Monk meditating under a frozen waterfall, hands pressed together
Shot 1. The waterfall. The water hits, he doesn't move.
Aerial wide shot of a snowy mountain with a tiny figure crossing the ridge
Shot 2a. The blizzard, wide. The scale of the suffering.
Pilgrim with a frozen beard pushing forward with a staff through heavy snow
Shot 2b. The blizzard, close. Ice in the beard, handheld camera.
Guru sitting by a fire in a cave with a steaming cup and the Understory tin beside him
Shot 3. The cave. Prayer flags, fire, and the product waiting on the stone.
Extreme close-up of the guru's face holding the steaming cup
Shot 4. The shot everything rides on. One second of calm before the grimace.

The animation

With the keyframes approved, each image became the first frame of its video clip using Seedance 2, the most capable model for complex physical movement and cinematic scenes.

Each shot was generated with prompts designed for that scene's specific movement.

Shot 1Slow push-in toward the monk. The water hits, he doesn't move.
Shot 2aWide aerial. The camera drifts laterally as the pilgrim struggles.
Shot 2bHandheld camera shaking with the wind. Ice in the beard.
Shot 3Gentle dolly-in toward the guru raising the cup. The tin visible on the stone.
Shot 4Extreme close-up. One second of calm, then the contortion, then the eyes opening with absolute clarity.
Shot 5Elegant orbit around the tin. Firelight on one side, cold light on the other.

The audio

The voice · Elias

We chose the Elias voice from Runway's catalog: male, aged, American, with a warm gravity that makes even the most absurd line sound like ancient truth. The four lines were recorded separately so we could sync them frame by frame with each shot.

The sound of the grimace

For Shot 4, instead of music or voiceover, we generated a disgust SFX with Seed Audio: the sound of someone taking a sip and reacting viscerally. A single gasp. A guttural sound. Silence.

The music

A bed of Tibetan singing bowls and low drones, generated with Lyria 3 Pro. It comes in at second zero and cuts dead at 0:21, right before the grimace. The sudden silence is part of the joke.

The edit

All editing happened inside Runway's timeline: six video clips on Track 0, voiceover and SFX on Track 1, music on Track 2.

The most critical moment in the edit: Shot 4 ended with the monk almost smiling. We caught it before rendering and cut the clip dead, right as he brings the cup to his lips, cutting to the product orbit. The joke is saved by a single frame.

Final duration: exactly 30 seconds.

What we learned

Silence is a production decision, not an absence

The most powerful scene in the spot has no audio. You have to build that actively: no background music, no voiceover, nothing filling the void.

Keyframe first, always

Generating the reference image before the video saved time and credits. What you see in the keyframe is what you animate.

The voice does half the comedic work

Elias saying "Tastes like misery" with absolute seriousness is funnier than any visual effect we could have added.

A good brief is a good spot

The concept, zen suffering in a tin, solved everything. Tone, visuals, audio, humor. It was all in that one line.

The result

Built entirely in Runway. No external tools. No stock footage. No studio.

Understory. Tastes like misery. Brings clarity.
