Every launch needs a video. Few ship one.
A short video is what social feeds, YouTube and the App Store preview slot all run on — and it is the launch asset most makers skip, because it has meant learning a video editor.
Video editors are a detour
Timelines, keyframes and render settings are a second craft to learn the week you are trying to ship.
Every feed wants a new shape
Reels and Shorts are 9:16, YouTube is 16:9, feed posts are square and App Store previews have their own exact sizes.
Your screens are already done
The designed screenshots are the storyboard — rebuilding them in another tool is where the afternoon goes.
Your screenshots are already the storyboard
Pick a screenshot set and every frame becomes a scene, in order, with the same device frames, fonts and backgrounds as your store listing. A template adds a title card and an end card; a style sets the transitions, camera motion and how each headline and phone animates in.
- ✓Drag scenes to reorder and drag an edge to change how long each one runs
- ✓29 transitions, 27 entrance animations and 17 camera motions, previewed as moving tiles — or 10 styles that set them all at once
- ✓A rendered 3D phone with eight camera moves, in any body colour, showing your own app screens
- ✓Make it for me: AI reads your screenshots and app brief, picks the template and writes the title and end cards

One video, every shape a feed asks for
Choose where it will be posted and the canvas is set for you. Scenes keep their own layout and are fitted into the frame over a full-bleed copy of their background, so a portrait screenshot still looks deliberate in a landscape video.
- ✓Vertical 9:16 for Reels, TikTok and Shorts; square for feed posts
- ✓Landscape 16:9 for YouTube — and the Play Store preview video, which is a YouTube link
- ✓App Store preview sizes with Apple’s 15–30 second window checked before export

Everything a launch trailer needs
Every scene opens in the same editor as your screenshots: device frames, text, shapes, images and backgrounds, placed anywhere.
Upload an MP3 or M4A, pick where it starts, set the volume and fade it out. Try it on any plan; export with Pro.
Upload a capture of your app and it plays inside the phone, or full-frame with a caption. Try it on any plan; export with Pro.
Your app screen on a rendered 3D phone you place like any element: spin, orbit, rise, drop in, flat lay, duo or a fan of three, in any colour.
Smoother motion for YouTube and your landing page. App Store previews stay at Apple’s 30 fps.
Make and export a real 720p video before you pay for anything.
Your screens in, a trailer out
Start from scratch, or from the set you design for the store — see the App Store screenshot generator and the Play Store screenshot generator. Listing copy, legal pages and a landing page are in the same Edok Studio app launch kit.
