352x288

352x288 is a standard digital video frame size that specifies a width of 352 pixels and a height of 288 pixels. It is widely known as a CIF (Common Intermediate Format) resolution and has been used as a baseline in several video coding standards and applications, particularly in PAL-based systems.

In practice, 352x288 is associated with the CIF level used by early video codecs such as H.261 and H.263, and it has appeared in MPEG-1 at low bitrates. The resolution can be displayed with either square pixels or non-square pixel aspect ratios, depending on the intended display format. With square pixels, the display aspect ratio would be roughly 1.222:1; to render the image as standard 4:3 video, a pixel aspect ratio near 1.09 is commonly applied.

Aspect and context: 352x288 is tied to television standards originating from PAL/SECAM regions, where 25 frames per second (or 50 fields per second) were typical for standard-definition video. As a CIF size, it sits between QCIF (176x144) and higher SD resolutions, providing a compact option for low-bandwidth video and early digital conferencing.

Modern relevance: While 352x288 is less common in new productions, it remains relevant for legacy video material, certain surveillance systems, and some older conferencing setups. It is often cited in discussions of historical video formats and the evolution of digital video compression.
