App Preview Converter

Turn any screen recording into an app preview that App Store Connect accepts. App Store Connect rejects app previews for reasons it rarely explains well: the video runs 14 seconds instead of 15, the resolution is off by a few pixels, the frame rate is 29.97 instead of 30, or there is no audio track at all. App Preview Converter handles all of it in one pass. HOW IT WORKS 1. Drop in a screen recording from your iPhone, iPad, Mac, or the Simulator. 2. Trim the part you want on a filmstrip timeline built around the 15-30 second rule. 3. Pick the device and orientation you are submitting for. 4. Export. The file is ready to upload. BUILT AROUND THE REQUIREMENTS - Exact resolutions for iPhone, iPad, Mac, Apple TV, and Vision Pro - Portrait and landscape output - H.264 video at a constant 30 fps - AAC stereo audio, added silently when your recording has none - Rec. 709 color, the standard App Store Connect expects - Every export is verified before it lands on disk A TIMELINE THAT KNOWS THE RULES You cannot accidentally build an invalid preview. The handles stop at 15 and 30 seconds, and once you hit the limit, dragging slides the whole selection along the video instead of breaking it. Click anywhere on the filmstrip to jump the preview to that exact frame. RECORDING TOO SHORT? STILL FINE A 9-second recording does not have to be reshot. Turn on Extend to 15 sec and the last frame holds until the preview reaches the App Store minimum. FIT OR FILL, SEEN BEFORE YOU EXPORT Fit shows the whole recording with letterbox bars. Fill crops to the edges. The preview updates the moment you switch, so what you see is what uploads. PRIVATE BY DEFAULT No account, no upload, no network access at all. Your recordings are converted on your Mac and never leave it. Made for developers who would rather ship than argue with ffmpeg flags.
