The Hook
“(No spoken dialogue — consistent rhythmic 'click' sound, low-frequency sub-bass drone, 'whoosh' sound at 0:04)”
Product Reveal
“(No spoken dialogue — subtle high-frequency 'ping' at 0:05, rhythmic 'click' sound continues)”
Feature Teaser
“(No spoken dialogue — rhythmic 'click' sound, sub-bass drone, significant sub-bass drop/impact with resonant 'thump' at 0:08)”
Call to Action
“(No spoken dialogue — sustained ethereal pad sound fades out)”
Synthesizable in Remotion · key components of the cli-terminal-launch template.
Text appears character by character, simulating a user typing in a command-line interface, accompanied by a blinking cursor.
Utilize Remotion's `Sequence` and `spring` for cursor blink. For text, use `interpolate` to reveal characters based on `frame` and `durationInFrames`, applying a monospace font.
Blocks of text or new lines of output appear instantly or with a very rapid fade-in, mimicking system responses in a terminal.
Employ `AbsoluteFill` with `spring` or `interpolate` for opacity from 0 to 1 for each line or block of text, ensuring a quick, almost instantaneous reveal.
A line of text indicating a process (e.g., 'Thinking (0s)') with dynamically updating numbers or symbols, often accompanied by a subtle dot animation.
Use `interpolate` to animate numerical values or symbols within a text string. A `loop` or `spring` can be used for the blinking dot or subtle movement of status indicators.
Purpose. Establish the familiar developer environment and initiate the product installation.
Execution. A clean terminal window with a user typing a `curl` command to install 'fx'.
Purpose. Introduce the 'fx' agent and its core functionality.
Execution. The 'fx' command is executed, showing its version and a prompt for commands.
Purpose. Demonstrate the interactive capabilities and responsiveness of the AI agent.
Execution. User types 'hello world', and the system displays a 'Thinking' status.
Purpose. Showcase the AI's intelligent response and readiness for further interaction.
Execution. The AI responds conversationally, 'Hello! What can I help you with today?'
Objective
Launch a new CLI-based database migration tool called 'MigrateX'.How the recipe adapts
The video would open with a user typing 'npm install -g migratex' in a terminal. This would be followed by a rapid output showing installation progress. Then, the user would type 'migratex init' and 'migratex apply --env=production', with the system displaying 'Running migrations (3s)' and then 'Migrations complete!' The sound design would feature distinct clicks for typing, a 'whoosh' for installation completion, and a deep 'thump' for migration application, ending with a subtle success chime.Scene durations (4 scenes, 11.4s)
