Videók

Videók, the Hungarian plural form of video, refer to motion pictures or video recordings. They are typically digital files that contain visual data and accompanying audio, along with optional subtitles and metadata. A video file is organized in a container format that bundles encoded streams and data.

Common containers include MP4, MKV, AVI, and MOV. The same video can be encoded with codecs such as H.264/AVC, H.265/HEVC, VP9, or AV1. The choice of container and codec affects compatibility, quality, and file size, while metadata and subtitles improve searchability and accessibility.

Historically, analog video used formats like VHS and Betacam, but digital video emerged in the 1990s. The growth of broadband and universal media players enabled online distribution and streaming, culminating in major platforms for user-generated content and on-demand services.

Delivery methods include progressive download and streaming. Streaming protocols such as HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH) adapt quality to network conditions. Video is widely used in entertainment, education, journalism, marketing, and communications.

Legal and ethical issues include copyright, licensing, and privacy. Video production and distribution often involve rights management, content moderation, and accessibility considerations like captions and audio descriptions to ensure inclusivity.
