Link: https://ratio.select I do visuals for live shows, and every gig meant rebuilding test cards in Photoshop for odd screen sizes. So I built a resolution and aspect ratio calculator that also draws the test card for whatever size you type. It now does LED walls in panels, saves every screen of a show for one batch export, and renders seamless MP4 test loops with timecode and a sync beep, all in the browser with nothing uploaded. Attach the tour reel. Happy to answer questions about how it was built.   submitted by   /u/Successful_Net2201 [link]   [comments]
