Enum BitDepth 

pub enum BitDepth {
    Auto,
    EightBit,
    TenBit,
}

Output bit depth — bits per sample. The on-disk pixel format is derived from this (the encoder is always AV1 4:2:0, the web-safe chroma subsampling): 8-bit → yuv420p, 10-bit → yuv420p10le (le = little-endian 16-bit words holding 10 valid bits). Bit depth is one axis; gamut + SDR/HDR transfer is the orthogonal ColorPolicy axis.

You rarely set this by hand: Auto derives it from the color policy.

Variants

Auto

Derive depth from the ColorPolicy: 8-bit for an SDR tonemap, 10-bit for HDR (Hdr10 / Hlg), the source’s own depth for Passthrough. The default — the right choice almost always.

EightBit

Force 8-bit 4:2:0 (yuv420p) — universal web compatibility.

TenBit

Force 10-bit 4:2:0 (yuv420p10le) — higher precision (banding-free gradients), and required by the HDR policies. Needs a 10-bit-capable encoder: NVENC (nvidia), AMF (amd), QSV (qsv), or ffmpeg.

Trait Implementations

impl Clone for BitDepth

fn clone(&self) -> BitDepth

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for BitDepth

impl Debug for BitDepth

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for BitDepth

fn default() -> BitDepth

Returns the “default value” for a type.

impl Eq for BitDepth

impl PartialEq for BitDepth

fn eq(&self, other: &BitDepth) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
