- Description
- An RMVB file is a Real Media video file compressed using a variable bit rate, which is optimized for the content of the video. It is a newer variation of the standard Real Media (.RM) file format that allows for more efficient compression.
- A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
