How the pan-and-zoom is built, what governs the quality of what comes out, and where your photo goes. (Nowhere. It goes nowhere.)
Settings → Export quality. There are three choices, 720p, 1080p, and 4K, and 1080p is the default, because it's the right trade for something headed to Reels or Stories. Pick 4K when the video is going somewhere that deserves it, and expect a larger file.
Because you've framed a crop tighter than the photo has detail to fill. PanPan will still export it, but it never upscales beyond the photo's real resolution, inventing pixels only makes a soft video look worse. The warning is telling you the closing crop is asking for more than the photo has. A higher-resolution source photo, or a slightly wider crop, fixes it.
It picks the move for you. PanPan looks for the subject of your photo, usually a face, and builds a slow push toward it. When it can't find a subject it falls back to a centred zoom, so Auto always hands you something rather than shrugging. Treat it as a starting point: everything it chooses can be adjusted by hand afterwards.
The presets give you a single move: one opening crop, one closing crop. Customize lets you chain several, so the camera can drift left, settle, then push in. You can also add a hold on any frame, which parks the camera there for a beat before the next move begins, the thing that makes a slow reveal feel deliberate rather than restless.
Vertical for Reels, Stories, and TikTok; square for a grid post; widescreen for YouTube or anything that'll be watched on a laptop. You choose the format up front, and the framing you see while you drag is the framing that exports.
No. The photo is read, the video is rendered, and both stay on your device. No server, no account, no login. The result leaves your phone only if you share it.
No. PanPan writes a new video and never touches the photo it read from.
To read the photo you pick, and to save the finished video back to your library. iOS asks for those separately.
A single small banner, no interstitials, no video ads. In regions that require it you'll see a consent prompt the first time, and Settings → Manage Privacy Choices lets you change your mind later.
Apple's App Tracking Transparency prompt. Say no and nothing about the app changes except that the banner shows less relevant ads.
No account, no sign-up, no subscription. PanPan is free and works offline.
