A small-file image is an image designed to use the least possible bandwidth in online transmission. Because streaming video is responsible for 1% of global warming, by some calculations, we need to reduce the file size of streaming media. For moving images, the Small File Media Festival () suggests a goal of 1 megabyte per minute. (For comparison, a 720 x 1080p high-definition video with frame rate of 24fps is anywhere between 60 and 350 MB/min). You can make your movie files small by compressing them with a codec like Handbrake or H.264: to retain image quality before compression, move the camera slowly and use a shallow depth of field. Or use 鈥渙bsolete鈥� technologies. Or use GIFs. Or reduce the frame rate. Or substitute moving images with still images, some kinds of animation, or text and keep a rich soundtrack, since sound uses less file space. If you still long for lush, high-resolution images, enjoy them in physical space rather than online. Laura U. Marks
