60 fps

Double the usual thirty. A camera at 60 fps takes twice as many samples of the motion in front of it, so fast movement stays crisp where it would otherwise smear, which is why gameplay capture and sport are shot and delivered at that rate. The second use is slow motion, since 60 fps footage dropped onto a 30 fps timeline runs at half speed and still plays one frame at a time, so it stays smooth. The trade-offs are storage, heat and the look. A shorter shutter comes with the frame rate and the picture reads as sharp and video-like, further from the motion blur people associate with film, which is why cinematic work stays at 24 or 25.
