RetroClip - Instant replay for your Mac

@rrhoover It's not. It runs completely locally. In fact, it's sandboxed so it is prevented by macOS from doing any networking at all.

@jacqvon Unlike other screen capture tools for macOS, RetroClip doesn't record to an ever growing file on disk, but instead just keeps track of the last 30 or 60 seconds in memory. This means you can leave it running all the time, and press the keyboard shortcut whenever you want to save a video retroactively, rather than having to plan ahead what you're going to capture. This makes it perfect for gamers to capture unexpected exciting moments, or for software developers to capture pesky bugs that are hard to reproduce.

@alexanderspoor I haven't done a thorough benchmark, but I would expect the battery life impact to be pretty minimal. The hardware video encoder is very efficient. In general, you can keep an eye on which apps are adversely affecting your battery life by clicking on the battery icon in the menu bar, as well as by using the Energy tab in Activity Monitor.

@thealexfreeman Do you ever need to show somebody how to do something on your computer, and a screenshot isn't enough? Or do you ever need to file a bug report with a piece of software and you want to show the steps you took? Or do you ever play games and you want to save a clip of some cool gameplay? Those are the main use cases. One way to think of it is what Live Photos are to photos, RetroClip is to screenshots.
