RLE stands for Run Length Encoding and is a general lossless compression method. It is used in many codecs after lossy compression. But some old codecs use only RLE.
- In MOV files, 'rle ' (lower case) indicates Apple QuickTime RLE.
- In AVI, BMP and ASF files, RLE indicates Microsoft RLE.
- Here's a list of all the known RGB bitmap/BMP formats: http://www.fourcc.org/rgb.php - including:
