![]() ![]() ![]() Frame Rate: The frequency or rate at which consecutive images are displayed.Constant bitrate maintains a constant bitrate per segment, regardless of the complexity. For example, higher bitrate for action-packed scenes in a movie and a lower-bit rate for slow scenes. VBR and CBR: Variable bitrate encoding varies the output bits over time.The higher the bits, the more the picture quality increase-but so does file size. Bitrate: The number of bites you're allowing the tool to describe each frame of the video.Some settings are global, i.e., similar from codec to codec or specific to an individual codec. Depending on the codec, this encoding occurs in one of two ways: lossy or lossless compression.īefore we dive into the formats, you should be aware of the parameters that will directly affect the quality of the finished video. But principally, you have to maintain the trade-off between image quality, file size, processor usage, and popularity. Knowing when and when not to use a codec is important throughout the process of post-production, compression, and final delivery of your content. There are dozens of different codecs, and each uses a different technology to encode and compress your video file. Codecs use algorithms to effectively shrink the audio or video file size and then decompress it for playback, editing, or when needed. It is an encoding tool that processes video and stores it in a stream of bytes. What Is a Codec?Ĭodec is an acronym that stands for compressor/decompressor or coder/decoder. You could spend weeks studying technologies that are useful only for a smaller number of applications, so instead, we're going to focus our attention on what technologies you'll use for video encoding, understanding the trade-offs and playback needs. ![]()
