Expand description

Result of comparing two encoding passes.

Fields§

§reference_label: String

Label of the reference (typically single-pass) pass.

§candidate_label: String

Label of the candidate (typically multipass) pass.

§ref_avg_qp: f64

Average QP of reference pass.

§cand_avg_qp: f64

Average QP of candidate pass.

§ref_qp_std_dev: f64

QP std dev of reference pass.

§cand_qp_std_dev: f64

QP std dev of candidate pass.

§ref_total_bytes: u64

Total bytes of reference pass.

§cand_total_bytes: u64

Total bytes of candidate pass.

§ref_size_std_dev: f64

Frame size std dev of reference.

§cand_size_std_dev: f64

Frame size std dev of candidate.

§candidate_qp_equal_or_better: bool

Whether the candidate has equal or better average QP (lower is better).

§candidate_qp_more_consistent: bool

Whether the candidate has lower or equal QP variance.

§candidate_smoother_bitrate: bool

Whether the candidate has a smoother bitrate distribution.
