One export set that fits every submission form without redoing it each time.
Nearly every directory asks for the same handful of images at slightly different sizes. Export the set once and submissions stop being an afternoon each.
No personal data, no half-loaded states, no browser bookmarks bar. Crop to the interface, not the desktop.
1280x800 for the standard gallery, 1600x900 for wide heroes, 1200x630 for OG, and a 512x512 square icon on a solid background.
Product name, one line of promise, one screenshot fragment. It gets rendered at thumbnail size in a feed.
No intro slide, no music, no face. Start inside the interface on the first frame, because most viewers leave by second ten.
