Stop Frame

Stop Frame is a technique in which you physically manipulate an object tro create the illusion of motion. To creathe this your chosen object is required to be moved little by little and taking individually photographed frames, this will produce the illusion of motion when you have played the frames in a continuous series, which can be done through the use of computer technology by putting the series of frames into Stop Motion software or even into Adobe Premiere. Movable jointed clay figures are often used in stop motion due to their greate ease of movement. Although they are useful it is not always necessary to use figures and in turn many stop motion films can involve using humans which can create interesting outcomes. here is an example of a stop frame animation that uses this technique.



Persistence of Vision

The Persistence of vision is a theory that an afterimage is thought to persist for around one twenty-fifth of a second on the retina,  this is believed to be an explanation for motion perception. The true reason for perception of continuous light is Flicker fusion.

 

 

A critical part of understanding the visual perception phenomena is that the eye is not a camera and in turn does not see in frames per second. In other words this vision is not as simple as light registering on a medium, because the brain has to make sense of the registers data the eye has provided and constructs a coherent picture of reality. Joseph Anderson and Barbara Fisher argue that the phi phenomena privileges a more constructionist approach to the cinema.

 

Frame Rate

Frame rate or better known as frames per second / FPS, is the rate at which a device produces unique consecutive number of images called frames. This term is used to apply equally well to film and video cameras, computer graphics. Most often expressed in frames per second it can also be expressed as progressive scan monitors in hertz.

 

 

The motion picture industry utilises traditional film with a standard filming and projection format of 24 frames per second. although Historically, 25 fps was used in some European countries as shooting at a slower frame rate would create a faster motion when it was projected, when shooting at a frame rate higher than 24 fps it creates a slower motion once projected. a further example of the historical experiments within frame rate is that they were not widely accepted by Maxivision 48 and Showscan, this was developed in 2001 by Douglas Trumbull, Special effects creator for Space Odyssey.

 

Here is an example of how Frame Rate orks giving a comparison of the differences bettween more and fewer frames. as you can see from the image the piece showing the use of 30 fps is much more clear and gives a smoother effect,  where as the piece used for 15fps is much more blurred within the motuion of it. this is why more framesd are used as it creates a better picture and makes it much smoother too watch overall for the viewer meaning you dont get the motion blurring.
