How to play 24 fps video smoothly on a 60Hz display?

Solution 1:

Check out SmoothVideo Project:

SVP allows you to watch any video on your PC file with frame interpolation (like you can watch it on high-end TVs and projectors). It increases frame rate by generating intermediate animation frames between existing ones to produce very smooth, fluid and clear motion. The technology is well-known for a while ("TrimensionDNM", "Motion Plus", "Motionflow" and others), but now it's available for free to PC users with simple GUI and just a couple of mouse clicks.

Solution 2:

I don't know of a player that can do that on the fly, but you can convert any video of 24/25fps into a nice 60fps video by re-encoding the video with interframing.

here is a very nice step by step tutorial to do it. It includes before/after video samples. http://www.spirton.com/convert-videos-to-60fps/
