Why movies and video games look the way they do at differing frame rates

NewImage

Simon Cooke goes into an in-depth explanation on why movies and video games look the way they do at differing frame rates.

Let’s end this debate once and for all. Humans can see frame rates greater than 24fps (although plenty of people will argue that they can’t on the internet). I’ll explain more in a future post if necessary, but let’s take that as read.

Once you’ve accepted that fact, the next question is why do movies at 48fps look “videoy”, and why do movies at 24fps look “dreamy” and “cinematic”. Why are games more realistic at 60Hz than 30Hz?

The answer to all of this lies in two things – ocular microtremor, and center-surround receptive fields in the retina. And it predicts where the cut-off lies as well.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
