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.
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.
