- Description
- Video file encoded with the MPEG-2 codec, which is mainly used for over-the-air, satellite, and cable digital TV signals and DVD video; uses lossy compression for audio and video to significantly reduce the size of the video data; not as efficient as the H.264 format.
- 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.
