Video and audio basics – About video and audio encoding

Recording video and audio to a digital format involves balancing quality with file size and bitrate. Most formats use compression to reduce file size and bitrate by selectively reducing quality. Compression is essential for reducing the size of movies so that they can be stored, transmitted, and played back effectively. Without compression, a single frame of standard-definition video uses nearly 1 MB (megabyte) of storage. At the NTSC frame rate of approximately 30 frames per second, uncompressed video plays at nearly 30 MB per second, and 35 seconds of footage takes up about 1GB of storage. By comparison, an NTSC file compressed in DV format fits 5 minutes of footage into 1 GB of storage at a bitrate of about 3.6 MB per second. To compress video for distribution at the highest possible quality, select the smallest compression ratio that delivers video within the file size and bitrate constraints of your target delivery media and playback devices. When exporting a movie file for playback on a specific type of device at a certain bandwidth, you choose a compressor/decompressor (also known as an encoder/decoder, or codec), to compress the information and generate a file readable by that type of device at that bandwidth.
