But quality/size ratio of output produced by different implementations of the same specification can also vary.Д®ach compression specification defines various mechanisms by which raw video (in essence, a sequence of full-resolution uncompressed digital images) can be reduced in size, from simple bit compression (like Lempel-Ziv-Welch) to psycho-visual and motion summarization, and how the output is stored as a bit stream. A codec is not a format, and there may be multiple codecs that implement the same compression specificationВ вЂ“ for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification. The quality the codec can achieve is heavily based on the compression format the codec uses.

General software characteristicsВ вЂ“ for example:.Performance characteristics such as compression/decompression speed, supported profiles/options, supported resolutions, supported rate control strategies, etc.

Video quality comparisons can be subjective or objective. Commonly video quality is considered the main characteristic of codec comparisons.

Video quality per bitrate (or range of bitrates).

The following characteristics are compared in video codecs comparisons:
