Image and video decision
Swiftship Previews
A single experienced developer can build and maintain a smaller self-hosted replacement (desktop app using AVFoundation/ffmpeg) in a multi-week effort; lossless-cut shows the core editing/exporting functionality is achievable in open source.

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. All Swiftship Previews alternatives, with the arithmetic →
What a replacement has to do
- Drop device screen recordings → trim/reorder/add intro/outro → choose background music → export Apple-compliant preview video
What it still won’t have
- Polish and edge-case handling for the variety of iPad aspect ratios
- Built-in licensed music library and curated presets
- Commercial-grade UI/UX and one-year update support included by vendor
- Apple-signed distribution infrastructure and marketing
- Customer support and refund handling
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a macOS (Swift/SwiftUI + AVFoundation/FFmpeg) app that produces App Store preview videos from iPhone/iPad screen recordings. Core features: drag-and-drop import of recordings, clip trimming and reordering UI, speed control, intro/outro overlay with logo and tagline, background music upload and mixing, and an export pipeline that enforces Apple App Preview specs (resolution, codec, bitrate, framerate, color space). Include local-only processing (no uploads), single-Mac license activation, codesign and notarization scripts, error handling, and automated unit/UI tests for import/export flows. Out of scope: built-in licensed music library and a web backend. Provide packaging for distribution (signed .app or .pkg) and a short README with notarization and distribution steps.

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.
