What is a Video file?
A video file is a digital container that stores moving images, often paired with audio and metadata such as subtitles, chapters, and cover art. Common extensions include .mp4, .avi, .mkv, and .mov. Inside the container, you’ll typically find compressed streams encoded with codecs like H.264, H.265/HEVC, or VP9 for video, and AAC or MP3 for audio. Video files balance size and quality through compression, making them practical for streaming, archiving, and editing. Their wide ecosystem support has made them the standard format for entertainment, education, and social media platforms.
