 
 <prompt> Wetin differences allow make happen for still frames? Based on di previous question, write one context wey contain di answer. E fit be 1 - 20 sentences. Context: <response>: Video data fit be represented as a series of still image frames. The sequence of frames get spatial and temporal redundancy wey video compression algorithms dey try eliminate or code for smaller size. Similarities fit dey encoded by only storing differences between frames, or by using perceptual features of human vision. For example, small differences in color dey hard to perceive pass changes in brightness. Compression algorithms fit average a color across these similar areas to reduce space, in a manner similar to those used in JPEG image compression. Some of these methods dey inherently lossy while others fit preserve all relevant information from the original, uncompressed video.
