Run-Length Encoding in Video Compression

Run-length encoding (RLE) reduces video file size by representing sequences of identical pixels with a single value and the length of the run. It identifies consecutive pixels with the same color or intensity and replaces them with the pixel value and the number of consecutive pixels with that value. RLE is highly effective for video sequences with large areas of uniform color or gradual transitions. However, it is not effective for random data and provides relatively low compression ratios compared to more sophisticated codecs. RLE is often used as a component within more complex video compression algorithms, typically applied to specific parts of the video data.

RLE replaces consecutive identical pixel values with a single value and a count, reducing redundancy. ---
