Cool site! I didn't know this was an established way of measuring input lag but it's how I've been doing it since I found out my Samsung phone came with a 960 fps camera. Manually counting frames with ffmpeg is a pain, but I never even thought to look for an app that does this. Thanks for sharing, I'll take a look around :)

Great app. I hope next iPhones have improved slow-motion camera modes. 1000fps will be a long shot but maybe 480/500fps.

What was the issue with your setup? TV not in game mode?

Never got to the bottom of it. TV was set to game mode, I tried various scaler settings on the deck itself, couldn't get it below about 90-100ms. I've tried on two TVs.

You can learn to play Space Channel 5 by tapping 100ms ahead of the beat. But I worried that if I succeeded too much, I'd end up doing everything that way: jumping red lights, taking espresso shots while they were still being poured etc.
