MP4 File Converter

Technically, MP4 files use the .mp4 extension and support multiple codecs including H.264 for video and AAC for audio. The format allows for efficient streaming by segmenting files and enabling progressive downloads. Its structure is based on the ISO base media file format, which organizes data into 'boxes' or atoms for flexible content management.

MP4 files can also include subtitles, still images, and metadata, enhancing the viewing experience. This versatility has made MP4 one of the most widely accepted video formats across different platforms and devices. Fun fact: MP4 became popular in the mid-2000s with the rise of portable media players like the iPod.
