Codec

A Codec is a technology used to compress and decompress video files, enabling efficient storage and streaming. Common examples include H.264 and H.265, which help reduce file sizes while maintaining quality, making it easier to transmit video over networks and store it on devices. Codecs are essential for various applications, including video conferencing, streaming services, and media playback.

Key Functions of Codecs

1. Codecs reduce the file size of audio and video by removing redundant or unnecessary data, making it easier to store and transmit.
2. When playing back a file, the codec decompresses the data so that it can be rendered or played back in its original form.

Types of Codecs

1. Audio Codecs: Examples include MP3, AAC, and FLAC, which are used for compressing audio files.
2. Video Codecs: Examples include H.264, H.265 (HEVC), and VP9, which are used for compressing video files.
3. Container Formats: While not codecs themselves, formats like MP4, AVI, and MKV can contain multiple codecs for audio and video within a single file.

Applications of Codecs

1. Codecs are used to deliver audio and video content over the internet efficiently.
2. They enable real-time communication by compressing video and audio streams.
3. Codecs are essential for media players to play various file formats.

Understanding codecs is crucial for optimizing media quality and performance, especially in applications that require streaming or high-definition content.
