What does encoding mean?

Encoding

Video encoding converts digital video files from one format to another or compresses raw uncompressed data using encoding algorithms. This compression reduces file sizes for easier storage, transmission, and internet streaming while maintaining acceptable visual quality. Encoders use codecs (coder-decoders) employing spatial and temporal compression techniques to eliminate redundant information between and within frames.

Different codecs like H.264, H.265, VP9, and AV1 have various compression methods balancing file size and quality. Video encoding involves selecting the optimal codec and configuring bitrate, resolution, frame rate, and settings to achieve the desired balance. The encoded video can then be stored, transmitted, or streamed for playback.
