Launch assets and App Store screenshots

One take gives you more than videos. ShowTake picks the take's key moments (the settled end of each step, or moments the agent marks) and writes screenshots and launch images from them, at the exact pixels each platform asks for. Every file is read back after export: pixel size, PNG or JPEG, no alpha channel, sRGB and the platform's file-size limit. Stills are a Pro feature.

Ask your agent

• "Make the App Store screenshots" → screenshot with bundle: "app_store": the required set for the take's platform. Add style: "marketing" for a background, a headline per shot (your step captions) and a device frame; all_sizes: true for every other accepted size.
• "Make a launch kit for Product Hunt" → export with bundle: "launch": one folder, exports/launch-kit/, with every file below and a README.md that says which file goes in which field.
• One size only → screenshot with preset, for example og_image or producthunt_gallery.

App Store screenshots can be plain captures or marketing images: Apple's Guideline 2.3.3 allows text and image overlays on screenshots as long as they show the app in use. App Previews are different: Guideline 2.3.4 asks for screen captures of the app, so ShowTake never frames them.

Notes

• The Product Hunt thumbnail is your app icon. ShowTake reads it from the app it built; if the app has none, the agent passes icon with a PNG.
• Hacker News takes no images: your Show HN post is a link, and the link preview (og_image) is what people see when it is shared elsewhere.
• Peerlist, Uneed, DevHunt, Fazier and Microlaunch publish no exact image sizes; the Product Hunt gallery images work there.
• Sizes are re-checked against each platform's own pages; full list with sources: video and image sizes.
