App Store Preview fixer
Choose a recording, select an Apple destination, set a 15–30 second range, preview its framing, and validate measurable output facts. Check Apple’s current documentation before submission.
Your video stays on this device. No upload, account, or server-side processing job.
Browser-local workspace
Choose one local MP4, M4V, MOV, or WebM file. JavaScript activates a browser-native preview and capability check; available conversions depend on the codecs supported by this device.
No upload, account, or server-side media job.
The App Store Preview flow reuses the same local trim, crop, resize, frame-rate, audio, and MP4 pipeline. It keeps the interface focused on a destination and a short clip instead of exposing a broad professional editing surface.
A completed receipt reports duration, dimensions, frame rate, codec, audio, bytes, and baked rotation. It cannot verify app-content accuracy, rights, licensing, or Apple’s editorial and policy decisions.
Private browser processing
Aftermath reads selected video bytes only in the current browser. Unsupported codecs are reported clearly rather than sent to another service. High-resolution conversion can use substantial device battery and processing.
