PreviewASO Screen - Turn any video into an Apple App Preview in seconds

Hey Product Hunt! I'm Daniel, a solo iOS dev, and I built PreviewASO Screen out of my own recurring headache. Every time I ship a new app, I hit the same wall: uploading the App Preview video to App Store Connect. A plain iOS screen recording never matches Apple's required spec (886×1920, H.264, 15–30s) — so it gets rejected, and I'm stuck opening Final Cut Pro or Canvas just to re-encode a video I already have. So I built the tool I wished existed: upload any video, trim it to 15–30s right in a phone-frame preview, and export it already in Apple's exact format — for iPhone, iPad, Mac, Apple TV, and even the 4K Vision Pro spec (which almost nothing else supports). It's free to try — 1 conversion/day, watermarked. Paid credit packs remove the watermark and skip the queue. This is a side project I'm building solo, so I'd genuinely love to hear from anyone who's shipped an iOS app and felt this exact pain — what would make this more useful for you?
