VBR (Variable Bit Rate)

VBR (Variable Bit Rate): To look good, close-ups may require more detailed information than distant panoramic scenes. VBR lets you adjust the capture rate so you get higher quality recording, and large files, only when you need it. VBR provides an alternative to Constant Bit Rate, and allows for efficient monitoring of audio or video complexity; you are able to increase or decrease bitrate accordingly. The result is a lower bitrate for simple scenes, a higher bitrate for more complex visual scenes, ultimately, yielding a better overall rendering in a smaller or the same file size. Variable Bit Rate mode is often measured as an “average” bit rate which allows for greater bit rates for complex scenes as needed. [ Audio Glossary ] [ Video Glossary ] [ Archive Glossary ]
