# Make an App Store preview video from a screen recording.

Page: https://crispdemo.com/app-store-preview-video

Your App Store page has screenshots and an empty App Previews slot. You have a two-minute screen recording from your iPhone and no time to learn a video editor.

CrispDemo has an App Store iPhone look: a portrait video of 886 by 1920 pixels, at most 30 seconds long. Your coding agent builds it from your recording, and your Mac renders the file.

## How to make an App Store preview video.

1. **Add a recording of your iPhone app.** Drop in the portrait screen recording from your iPhone as a MOV or MP4 file, or screenshots of the app. A video can use up to 12 files. Your original files are never changed.
2. **Pick the App Store look.** Under Where will this video be posted?, pick App Store. The look is 886 by 1920 pixels at 30 frames a second, and a video for it can be at most 30 seconds long.
3. **Ask for one flow in 15 to 30 seconds.** Your coding agent rebuilds the screens from your recording and writes the story. The App Store look shows your app's screen whole, with no device frame and no camera moves.
4. **Check the export, then upload it yourself.** Export the MP4 and check it against the App Store Connect requirements before you upload it. CrispDemo does not upload to App Store Connect.

## Before you upload.

- **A Gemini review of the finished video.** Gemini watches and listens to the rendered video and lists what to fix: the opening, legibility, framing, captions and more.
- **The same story for TikTok, Reels and Shorts.** Add a vertical look for each feed, or make a separate version when one of them needs a different cut.

## Which file does the App Store look export?

A portrait MP4 of 886 by 1920 pixels, with H.264 video at 30 frames a second and AAC sound. A video for this look can be at most 30 seconds long.

## Does it make iPad or landscape previews?

No. The App Store look is for iPhone, in portrait.

## Will App Store Connect accept the video?

CrispDemo does not check the video against Apple's rules, and we have not uploaded an export to App Store Connect ourselves. The video shows screens that your coding agent rebuilt from your recording, so compare them with your app and check the export against the App Store Connect requirements before you upload it.

## Can I use the screen recording from my iPhone?

Yes. Add the MOV or MP4 file. A portrait recording is shown whole inside the 886 by 1920 frame.
