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 checks actual bytes and duration plus the reported container, target dimensions, H.264 codec, frame rate, video bitrate, and AAC stereo facts. It does not certify progressive scan/profile level, enabled-track state, 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.
Check an App Store Preview video locally against the technical facts exposed by the current browser and the linked Apple requirements. Select one supported MP4, M4V, MOV, or WebM file; the workflow reports measurable container, duration, dimensions, tracks, and compatibility findings before any download. It does not verify creative content, rights, account settings, accessibility, or final App Store acceptance. Output operations keep one completed result in browser memory and are limited to 500 MB.
An authentic app demonstration video needs a technical App Store-oriented preparation check before submission.
Observed operation: Inspect the source, choose the supported preparation path and measure the completed output's container, tracks, duration and dimensions.
Review the result: Play the whole output and compare every technical receipt item with the current App Store Preview instructions.
Boundary: The route cannot certify content authenticity, rights, editorial review, enabled tracks or every Apple encoding requirement.
The selected video stays in the current browser session and is not sent to an Aftermath processing service. How local processing is verified.
Checks the displayed limits and reports or creates a local App Store-oriented video checklist and, when supported, a separately downloaded video result from one selected local MP4, M4V, MOV, or WebM file.
A local video result does not guarantee universal codec support, editorial suitability, or platform acceptance.
