Definition

Number of bytes used to represent a single video sample, which generally maps to bits per sample.

Controlled Vocabulary

free text

Example(s)

Files with a bit depth of 24 will usually be expressed as a 3-byte word size, however some applications may store 24-bit video in a 4-byte word.
