Image and video decision

Screen Studio

A competent engineer can implement a useful local screen recorder with automatic zooms and exports (core loop) using existing libraries, but matching Screen Studio's polish, device catalogue, hosted sharing, and cross-edge UX would take substantially more time and product effort—keep paying if you need turnkey polish and hosted features.

Open-source builds that already do this

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.

What a replacement has to do

Record screen + mic/webcam, automatically track and smooth cursor + apply zooms, edit timeline zoom regions, export to video/GIF, optionally generate local transcript

What it still won’t have

polished UX and animations tuned over many releases
shareable links / hosted previews
device frame catalogue and automatic iPhone/iPad model detection
hand-tuned export presets and wide-tested platform compatibility

Runnable build prompt

Not run yet

Build a native macOS app (Swift + AVFoundation for capture, SwiftUI for UI) that: 1) captures screen, selected window, webcam, microphone, and system audio; 2) tracks cursor position, applies smoothing and automated zoom framing with animated transforms; 3) exposes a timeline UI to add/drag zoom regions, trim and speed segments; 4) exports to MP4 (H.264/HEVC) and optimized GIF with selectable presets; 5) runs local transcription (OpenAI Whisper or VOSK locally) and exports subtitles. Out of scope: cloud-hosted shareable links, multi-OS support, app-store distribution. Include error handling for device/permission failures, unit tests for capture/export logic, and a small CI workflow to build signed developer builds.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
