Struct CodecTunePreset 

pub struct CodecTunePreset {
    pub codec: String,
    pub tune_name: String,
    pub options: Vec<(String, String)>,
    pub description: String,
}

Per-codec tune presets for content-specific optimization.

Each preset encodes recommended encoder parameters for a specific content type (film, animation, grain, screen, etc.) for a specific codec.

Fields

codec: String

Codec this preset applies to (e.g. “av1”, “vp9”).

tune_name: String

Content tune name (e.g. “film”, “animation”, “grain”).

options: Vec<(String, String)>

Recommended encoder options as key-value pairs.

description: String

Description of what this tune optimizes for.

Implementations

impl CodecTunePreset

pub fn av1_film() -> Self

AV1 film tune preset.

Optimized for live-action content with natural motion, subtle colour gradients, and moderate detail. Uses film grain synthesis to maintain perceived quality at lower bitrates.

pub fn av1_animation() -> Self

AV1 animation tune preset.

Optimized for animated content with flat colour areas, sharp edges, and less texture. Favours PSNR-based quality and aggressive deblocking.

pub fn av1_grain() -> Self

AV1 grain preservation tune preset.

Preserves film grain and high-frequency texture detail. Uses grain synthesis with higher fidelity parameters and disables aggressive denoising.

pub fn vp9_film() -> Self

VP9 film tune preset.

Optimized for live-action content using VP9-specific parameters.

pub fn vp9_animation() -> Self

VP9 animation tune preset.

Optimized for animated content with VP9-specific parameters.

pub fn vp9_grain() -> Self

VP9 grain preservation tune preset.

pub fn presets_for_codec(codec: &str) -> Vec<Self>

Returns all available tune presets for a given codec.

pub fn find(codec: &str, tune_name: &str) -> Option<Self>

Looks up a specific tune preset by codec and tune name.

pub fn option_count(&self) -> usize

Returns the number of encoder options in this preset.

pub fn apply_to_options(&self, options: &mut Vec<(String, String)>)

Merges this preset’s options into a CodecConfig’s options list.

Existing options with matching keys are overwritten.

Trait Implementations

impl Clone for CodecTunePreset

fn clone(&self) -> CodecTunePreset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CodecTunePreset

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

Formats the value using the given formatter.

impl PartialEq for CodecTunePreset

fn eq(&self, other: &CodecTunePreset) -> 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.
