AppPreviewCut vs LogCat Analyzer

App Previews are the short promo videos on your app product page. App Store Connect requires very specific formats and resolutions for each device for the videos to be uploaded and accepted. This app is built to create and edit those videos from your screen recordings—with file formats and encoding presets that match Apple developer requirements so you get it right the first time. Create a project, pick the device and orientation (e.g. iPhone portrait, iPad landscape, Mac, Apple TV, or Vision Pro). Trim and join your screen recordings, adjust speed, add B-roll, then export. The app uses the exact resolutions and video audio codec specifications required for each App Preview type, so you don’t have to look up dimensions or convert to a different format. FEATURES • Built for App Previews—formats and resolutions match App Store Connect requirements • Presets for iPhone, iPad, Mac, Apple TV, and Vision Pro (portrait & landscape) • Insert an introduction title screen • Trim and join screen recordings • Speed up or slow down clips • Per-clip volume and mute • Create title screen with app icon, title, and description • Add background track from our royalty-free stock music library EXPORT Choose a preset when you create a project; export uses that preset’s resolution and aspect ratio. No guessing—just pick the App Preview type you need and export. Save to Files, export to Photos, or AirDrop to your Mac to upload. Designed for light and dark mode with a clean, neutral interface so your screen recordings stay the focus. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
