What Does Standard Input Format Mean?

Standard Input Format (SIF) is a specific video format
developed by the MPEG that allows for specific resolution and transmission
protocols for digital video processing. SIF is used in DVDs and high-density
television technologies as well as other applications.


Techopedia Explains Standard Input Format

Video experts often compare SIF to another common format
called Common Intermediate Format (CIF). Other common formats include QCIF and
SCIF. Each of these have their own video resolution and other attributes. For
example, with SIF resolution at 352 × 240, and CIF resolution at 352 × 288, the
output of these two formats is not radically different. Developers and
engineers may also look at elements like interlace and frame rate.
