Video encoding is the process of converting raw video files into a compressed format that can be easily stored and transmitted. This involves using specific algorithms to reduce the file size while maintaining acceptable quality. Common encoding formats include H.264, H.265, and VP9, each offering different levels of compression and quality. The encoded video can then be played back on various devices, such as smartphones, computers, and smart TVs. Video encoding is essential for streaming services like YouTube and Netflix, as it allows for efficient delivery of high-quality video content over the internet.
