Nathan Ruberto · Launch Video Breakdown: Hook, Pacing & Motion Design

Today I'm coming out of stealth. I've been building Reflux - a natural language interface for chemical engineering simulation software. The tools that design every oil refinery, chemical plant, ASU, and carbon capture project on earth are running on software built in the 1980s. https://t.co/podTGCwgNV

AI Agent Live Demo with Founder PiP

Founder Authority & Technical Motion Graphics

Adapt it.

Replace founder video with new founder's introduction.
Update screen recording to feature the new AI agent's UI and target software.
Customize 'LiveAgentTerminal' text content to reflect the new agent's actions and output.
Adapt 'DynamicFlowsheetUpdate' to showcase automated interactions within the new software.
Adjust background music to a similar low-energy ambient electronic style.
Ensure PiP placement and styling remain consistent.

Launch overview & key findings

A 239.9-second founder authority & technical motion graphics launch video by Nathan Ruberto, unveiled on June 3, 2026 with over 1K views on X. Evaluated at a 8.5/10 hook score with an editing tempo of 1 cuts per minute, the production demonstrates Nathan Ruberto introduces Reflux, an AI agent that provides a natural language interface for complex chemical engineering simulation software. The video demonstrates Reflux's ability to automate tasks like building and modifying flowsheets, which traditionally run on outdated systems. The motion style is characterized by a direct founder address, a picture-in-picture overlay, and extensive real-time screen recordings showcasing the AI's dynamic interaction with the software, all set to a calm, ambient electronic score.

The Hook
Founder Introduction & Stealth Reveal
“Today I'm coming out of stealth. I've been building Reflux - a natural language interface for chemical engineering simulation software.”

Problem Agitation
Legacy Software & Reflux Agent Activation
“The tools that design every oil refinery, chemical plant, ASU, and carbon capture project on earth are running on software built in the 1980s. Reflux is a natural language interface for chemical engineering simulation software. So let's say I want to build a flash flowsheet.”
On screen
Reflux running agent Reflux thinking - Preparing the simulator run. - Starting agent. - Using deterministic Aspen flash skill. - Resolving component/property setup. - Resolved N-BUTANE, PROPANE with PENG-ROB. - Building Aspen flash model. - Starting Aspen from a flash component deck. - Creating connected FLASH2 topology. - Writing flash feed stream specifications. - Checking Aspen required inputs. - Running the flash simulation. ready Components: N-BUTANE, PROPANE. Assumptions: - Modeled as one Aspen FLASH2 block with one feed, one vapor outlet, and one liquid outlet. - Feed basis: 100 kmol/hr at 320.00 K and 10 bar. - Flash target: 300.00 K and 5 bar. RESULTS VAPOR T: 300 K P: 5 bar Flow: 49.846 kmol/hr

Product Reveal
Automated Flowsheet Modification
“Now let's say I want to add a heater upstream of the flash. Reflux is going to inspect the current flowsheet, disconnect the original feed from the flash, insert a feed heater, and then reconnect the feed to the heater and the heater to the flash.”
On screen
Reflux running agent preparing request - Inspecting current flowsheet. - Inspecting existing blocks. - Inspecting existing streams. - Found the current flash topology. - Inserting feed heater before flash. - Reading stream data. - Disconnecting original feed from flash. - Rerouting feed through heater. - Writing heater and flash parameters. - Inspecting flowsheet topology. - Checking Aspen required inputs. - Running the updated flowsheet. ready NOTES - FLASH1 is still temperature/pressure specified, so Aspen resolves the outlet split at the flash target conditions. - If the flash temperature remains fixed, an upstream heater can appear on the flowsheet without changing the equilibrium split. - Flash pressure target kept at 5 bar. Heater target: 360 K RESULTS Before heater Vapor fraction: 0.49846 Liquid composition: N-BUTANE=0.64435, PROPANE=0.35565 After heater

Motion
Dynamic screen recording with automated UI interaction, demonstrating the agent's ability to interpret and execute complex commands.
Feature Teaser
Advanced Simulation & Editing Capabilities
“And now we have a heater upstream of the flash. And we can see the results before and after the heater. So this is just a quick demo of Reflux. I'm really excited about what we're building here. And I think it's going to be a really powerful tool for chemical engineers.”

Synthesizable in Remotion · key components of the founder-agent-demo template.

PiPFounderOverlay

A live video feed of the founder is displayed in a small, fixed rectangle in the top-right corner of the screen, overlaying the main screen recording content.

+ Code construction recipe

Use a <Video> component for the founder's feed, positioned absolutely with `top` and `right` CSS properties. Ensure `z-index` is higher than the main screen recording <Video> component.

LiveAgentTerminal

A semi-transparent terminal-like window appears on the screen, displaying real-time text output from an AI agent, simulating thought processes and actions. Text appears to be typed out dynamically.

+ Code construction recipe

Implement a <Sequence> of <Text> components, each with a `typewriter` effect (using `interpolate` for `opacity` and `width` or `clip-path`) to reveal text character by character. Use a semi-transparent background for the container.

DynamicFlowsheetUpdate

Elements within a complex simulation software interface (e.g., flow diagrams, data tables) are automatically added, removed, or modified in response to the AI agent's commands, without manual user input.

+ Code construction recipe

Utilize a screen recording <Video> component. For specific UI elements that need to appear/disappear or change, consider overlaying transparent <AbsoluteFill> components with `opacity` or `scale` animations, or pre-rendering specific UI states and cross-fading between them.
