MPEG-4 vs. H.263: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 9, 2024
MPEG-4 is a broad, advanced video/audio compression standard; H.263 is an older, simpler video-only compression standard primarily for video conferencing.

Key Differences

MPEG-4, developed by MPEG (Moving Picture Experts Group), is a multimedia encoding and compression standard designed for high-quality audio and video formats. H.263, developed by the ITU-T, initially focused on low-bitrate communication, particularly for video conferencing.
