Prequel

Product Introduction

1. Definition: Prequel is a professional-grade, AI-assisted screen recording and video editing application for macOS. It operates as a local desktop application that leverages Apple's native media frameworks (VideoToolbox, Metal) for hardware-accelerated capture, compositing, and export.
2. Core Value Proposition: Prequel exists to automate the post-production workflow for screen-based content creation. Its primary value is transforming raw, static screen captures into dynamic, cinematic videos with professional zooms, framing, and polish—directly after recording, without requiring manual video editing expertise or time-consuming manual keyframing.

Main Features

1. Context-Aware Automatic Zooming: Prequel's core innovation is its automatic zoom generation. It records metadata on user interaction (clicks, typing bursts) during capture. Post-recording, its algorithm clusters these events to create dynamic zoom-ins on areas of activity (cursor, text input fields) and smooth zoom-outs during transitions. Each zoom is a fully editable keyframe animation with adjustable level, speed, tilt, yaw, and progressive background blur, rendered via the Metal API.
2. Non-Destructive, Post-Recording Framing & Composition: All visual composition is applied non-destructively after recording. The webcam feed is recorded as a separate layer, allowing users to reposition, resize (circle, squircle, rounded rectangle), and mirror the camera in any corner during editing. Backgrounds (including system wallpaper, gradients, solids) with customizable padding, corner radius, border, and shadow are composited in real-time using Metal.
3. Hardware-Accelerated Multi-Track Editing & Export: The application provides a streamlined, non-linear editing timeline for trimming dead air, with a visual audio waveform. It records system audio and microphone as separate, gain-controlled tracks. Export utilizes Apple's VideoToolbox framework for hardware-encoded H.264 or HEVC MP4 files at constant frame rates, supporting resolutions up to 4K and frame rates up to 120 fps, all processed locally on the Mac's media engine.

Problems Solved

1. Pain Point: It solves the tedious, time-intensive post-production process required to make screen recordings engaging. Traditional workflow involves manually adding zooms, keyframes, and effects in separate video editing software (like Final Cut Pro or Premiere Pro), a significant barrier for non-editors.
2. Target Audience: Primary personas include SaaS Educators & Course Creators, Software Developers & Engineering Teams (for code walkthroughs and bug reports), Product Managers & UX Designers (for feature demos and async reviews), and Content Marketers & Social Media Managers creating tutorials and promotional clips for platforms like YouTube, TikTok, and LinkedIn.
3. Use Cases: Essential for creating polished product demo videos, software tutorial content, asynchronous team presentations, bug report videos with clear focus, and social media clips (Reels, Shorts, TikTok) where vertical/landscape reformatting must maintain consistent visual composition.

Unique Advantages

1. Differentiation: Unlike basic screen recorders (QuickTime, OBS) that output flat footage, or cloud-based AI tools (like Loom's early AI features), Prequel is a native macOS app that performs all intelligent editing and high-fidelity rendering locally. It offers more granular, frame-accurate editorial control than fully automated cloud tools while being vastly more efficient than manual professional NLEs.
2. Key Innovation: The proprietary "interaction-to-zoom" algorithm that translates user activity (clicks, typing) into a sensible, editable first-pass edit is its key innovation. Coupled with a proportion-based, non-destructive composition engine (where framing is relative, not absolute), it allows for seamless aspect ratio changes (e.g., landscape to vertical) without breaking the layout—a major technical hurdle in traditional video editing.

Frequently Asked Questions (FAQ)

1. Does Prequel work on Intel Macs or Windows? No. Prequel is optimized exclusively for Apple Silicon Macs (M1, M2, M3, etc.) running macOS Sonoma (14.0+) or later. This allows it to fully leverage the unified memory architecture and dedicated media engine for efficient, high-resolution capture and export without dropped frames.
2. How does Prequel handle privacy and where is my data processed? All processing—recording, AI-driven zoom analysis, editing, and rendering—occurs locally on your Mac. No screen recording data or video footage is uploaded to the cloud for processing unless you explicitly use a separate "shareable link" feature after export, which is an opt-in action for a finished file.
3. Can I use Prequel to record applications that require high security, like banking apps? As a native macOS app using the system's Screen Recording permission, Prequel can capture any on-screen content you permit. However, users should always adhere to security best practices and policies when recording sensitive information. The local-processing model is beneficial here, as data never leaves the machine.
4. What are the limitations of the automatic zooms, and can I edit them? The automatic zooms are a starting point. Every generated zoom is a fully editable object on the timeline. You can delete them, adjust their timing, change their target (cursor, a drawn region, or text field), and modify their animation properties (speed, blur, curve). The automation is not baked into the final video.
5. What is the output quality and format for professional use? Prequel exports a single, constant frame rate MP4 file using hardware-accelerated H.264 or HEVC codecs. This is the standard delivery format for web video. Quality is limited by your source display resolution; exporting a 4K video from a 1080p screen recording will not add detail. For professional use, recording at your display's native Retina resolution provides ample pixel headroom for clean 1080p or 4K zooms.
