Struct BitrateModel

pub struct BitrateModel;

Expand description

Bitrate model for predicting bitrate from CRF and content complexity.

Implementations§

impl BitrateModel

pub fn predict(crf: u8, complexity: f32, codec: &str) -> u32

Predicts bitrate in kbps for a given CRF, content complexity, and codec.

Model: bitrate = complexity * base * 2^((crf - 28) / 6)

Codec-specific base bitrates (kbps):

h264: 2000
vp9: 1500 (typically more efficient)
av1: 1200 (most efficient)
hevc / h265: 1400
others: 2000

pub fn crf_for_bitrate(target_kbps: u32, complexity: f32, codec: &str) -> u8

Estimates the CRF needed to achieve a target bitrate.
