Step by step
Open a project's Video tab and click Choose a script. There are 15, each composed for its frame: landscape 16:9 for YouTube and your site, vertical 9:16 for Reels, TikTok and Shorts, and square for feeds.
The script opens already filled in — your screenshots, your captions and your background, placed scene by scene. Press play to watch it; nothing starts empty.
Every word is editable. Click a line in the panel and the preview jumps to that scene, then type — here the closing line becomes Stedo's own call to action.
Under Music, pick one of ten built-in tracks or upload your own. It plays with the video, loops to its length and fades out at the end.
Click a phone in a scene and upload any screenshot, or drag one from Finder straight onto a phone in the preview. It lives in this video only, so the screenshots in your set stay as they are.
Export MP4 renders the video at 1080p and 30 fps right in your browser, music included, and saves it to your downloads — ready for your site, socials or Product Hunt.
Building and previewing videos is free; exporting is part of AppStills Pro.
Under Videos, click New video and pick a vertical 9:16 script such as Reel: the same screenshots and captions, with new choreography for Reels, TikTok and YouTube Shorts.
Need an App Store app preview instead? Apple wants real footage of your app — select a phone in the editor, add your screen recording, and export it at the exact preview size.
