What is the purpose of codecs in video production?

The purpose of codecs in video production is primarily to compress and decompress data for transmission. Codecs are algorithms or software tools that encode and decode digital data, making it possible to efficiently store and transmit video files. The process of compression reduces the file size, which is crucial for streaming, downloading, or sharing videos over the internet, as it makes data transfer faster and less demanding on bandwidth. When playback is required, the codec decompresses the data, ensuring that the video plays smoothly and retains quality.

This function is essential in today's digital media landscape, as high-definition videos require significant amounts of data. Without codecs, managing the storage and distribution of video content would be challenging, and the ability to stream videos in real-time would be severely limited. Understanding how codecs work enables content creators to optimize their videos for various platforms and audiences, balancing quality and file size effectively.
