My First Slitscan Videos on YouTube
The majority of the images I create are 'photographic compositions'. That is, they are assemblages made from multiple images. Where do all the images come from? Video clips are a rich source that I use more and more often. How else can you take eighteen hundred pictures a minute? A minute of 720p video, at 30 frames per second, results in a file of over SIXTEEN HUNDRED megapixels. That's a lot of image data, and it's all neatly organized in a 'video cube' with dimensions of Height by Width by Time. I create still images from videos by effectively defining a two dimensional slice through the video cube. The resulting plane of pixels is presented as a flat image.
Suppose, however, I take the two dimensional slice I've defined and move it through the video cube from front to back, top to bottom, left to right, diagonally, or even just wandering along a snaking path? The result is a collection of slices from the video cube that can be presented as video frames, and that's a slit-scan video. |
