Movies are filmed in 24fps.They look real and have no slowdown. Film a movie in 60fps or whatever, it would be too fast and look stupid.....you could make a game not lagg at 24fps if you kept it solid there..30fps, i dont careJordanKid
movies are FILMED, not PLAYED. if you did any movie editing at all you would know this, anyone that has used tmpeg knows why films are shot at 24fps. if you were right then why play games at 30fps? why not lower them down to 24fps?
Movies run at 24 fps and they look perfectly smooth so surely 24 fps is enough for moving imagery to be perceived by the eye, right?
Ever had someone shine a bright light into your eyes? When they take the light away, you can still see an afterimage of that light for a bit. As the light surrounding you deepens the more the afterimage makes an impression on your retina. The same effect happens in the Cinema so that you perceive an afterimage of the previous frame, which to your mind is blended in with the next frame.
On the big screen, the image is projected in its entirety, one complete frame at a time, which in turn gives us an afterimage effect.
Films also have motion blur, so that much like the Visual Cortex, motion blur can help maintain the illusion of smooth moving imagery.
Let's talk TV. PAL runs at about 25 frames per second, whereas NTSC runs at about 30 frames per second. Now regardless of which format we choose here, neither of these is actually at a high enough frame rate to give us the perception of smooth moving imagery. What's that you say? Your TV looks fine? Of course it does, because the moving imagery you are looking at is also displayed at a higher refresh rate. Unlike the big screen, TV's don't display one image after another, but draw the image line by line horizontally, which relates to 60 drawing's or refreshes every second. For NTSC, you have 30 fps but 60 refreshes of the screen per second. This amounts to each frame being drawn twice and therefore we have a higher frame rate.
Again, like the big screen, Motion Blur makes its presence known. Want to see this? Go get an action DVD, anything with fast moving objects. Now pause it whilst that object is moving. Looks blurred doesn't it, yet the DVD has frozen that point of the film on one singular frame.
Using a succession of moving images, the two refreshes per frame fool us into believing there is two frames for every one frame. With the motion blur the eye believes we are watching a smoothly flowing picture.
I'm sure some of you out there are thinking, well I'm happy playing games at 30 fps, who are you to turn around and say different? Frankly I'm not. What I am saying is there are people out there who are not happy with 30 fps, and now hopefully you can understand why. CRT Monitors are considered 'Flicker Free' at about 72Hz for a reason, and simply put it's to compensate for the lack of motion blur, afterimages and other trickery we live with every day in TV and Films. The Human Eye is a marvellous, complex and very clever thing indeed, but even that needs a little help now and then. At the end of the day, it's all down to end user preference, but for me personally I prefer a flicker free display and flicker free gaming.
