MP4 (MPEG-4 Part 14) is a digital multimedia container format commonly used for storing video, audio, and subtitles. MP4 is the standard format for video sharing online, supported by virtually all devices and platforms. Municipalities use MP4 format for recorded council meetings, public information videos, promotional content, and archived video materials. The format balances quality with file size, making videos practical to stream online or download. Understanding video formats helps municipal communications staff share information effectively and ensures video content remains accessible to residents regardless of their devices or internet speeds.
