How many frames per second can the human eye see?

How many frames per second can the human eye see?

This is a tricky question. And much confusion about it is related to the fact, that this question is NOT the same as: How many frames per second do I have to have to make motions look fluid?

And it's not the same as: How many frames per second makes the movie stop flickering?

And it's not the same as: What is the shortest frame a human eye would notice?

Website beautifully explains and illustrates the relationship between smoothness of motion, frames per second and sensitivity of the human eye. Highly recommended reading.

And while you are at it, I suggest you read some of the other articles on the site, particularly the one about video codec comparison and de-interlacing. Enlightening stuff.

Timeline is also available for Facebook Pages that people can use to promote their website or business or event. Although you can change the cover photo as often as you like, it’s meant to be static – something which you design and leave it for at least a few weeks or months like a redesigned website. However, there are times when you may want to change the cover photo frequently and periodically to match event dates or some special promotion that you are running or plan to run.
