  • What Is Motion Graphic?

    May 3, 2011

    Motion graphics are inseparable from time. Time is an absolute natural rule and it is unchangeable. When we look at a painting on a canvas, the art work seems to be remaining still. But, it is technically not true. The substances of the paints and the wooden materials of the canvas are being corroded by the acids in the air. The painting is not moving because the speed of the chemical reactions occur very slowly. Therefore, every object on the earth can be optically explained as motion graphics. No object is infinite and the change in time is a fundamental notion of motion graphics.

    Human visual perception miscommunicates with thinking process in an activity of observing motion graphics. Basically, we do not precisely comprehend the motions that we see on a screen. Before Blue-Ray and HD recording technologies were developed, the best way of containing movies was DVDs. The movie on DVDs were known as having the finest quality. But, we also noticed that the excellence was composed by pixelated or blurred still images. Accustomed to DVDs, we sense an indescribable awkwardness in the motion of HD movies even though the still images on HD movies are perfectly clear. The unnatural feelings from watching HD movies can be explained by the miscommunication between optical cognition and our thinking process. The thinking process of understanding images as a motion needs time to alter its mode from DVDs to HD. Because HD movies have clearer images than DVDs, it takes longer time for viewers to learn the motion. Therefore, HD movies seem to be playing slower than DVDs. We all simply misunderstood what we saw.

    Machines also misread motion graphics due to the processing capability. A digital camera digitizes an optical image through the lens and memorizes it in a memory card. The mechanism has been developed well enough to take a quality image out of a fast moving object. In a short time of exposure, the computer in a camera reads out the image and saves. However, very interesting thing happens when the reading processing is slow. Image A is a picture of a speed cop that I took using the 2MP camera on my iPhone which has 128MB eDRAM memory unit and I was driving about 70mph. And the image of the speed cop on my iPhone turned out warped. I assumed that it was an error. So I used another digital camera, Canon G12, that has bigger memory and faster computer in it. I took pictures of the letters on a running treadmill. Image B is from my iPhone and image C is from the G12. You can see that Image B is distorted. On the other hand, Image C is not misrepresenting the letters, rather it is just evenly blurred by the exposure setting. In short, it was a sensor* issue. A digital camera miscalculates the image from moving object and saves it incorrectly.

    The more we know about motion graphics, the better we can understand time. Some motions are too slow to sense. Other motions are too fast to take. Time exists between the images and expresses the relationship in motion graphics. Thus, my answer to the question, "What is motion graphic?" would be:

    Motion graphic is a sensitive method of expressing the passing of time.
