WebNov 27, 2012 · With CRF encoding you are picking the quality. The encoder uses whatever bitrate is necessary to deliver that quality. With bitrate based encoding you are picking the bitrate (and hence the file size). The encoder delivers whatever quality it can at that bitrate. Different videos will require different bitates to maintain quality. WebMay 24, 2024 · Hello, I Really need some help.
