Enum QualityMode 

pub enum QualityMode {
    Low,
    Medium,
    High,
    VeryHigh,
    Custom,
}

Quality preset levels.

Variants

Low

Low quality (faster encoding, lower bitrate).

Medium

Medium quality (balanced speed and quality).

High

High quality (slower encoding, higher bitrate).

VeryHigh

Very high quality (very slow encoding, very high bitrate).

Custom

Custom quality with specific parameters.

Implementations

impl QualityMode

pub fn to_crf(self) -> u8

Converts quality mode to a CRF value for most codecs.

Returns

CRF value (lower = higher quality):

• Low: 28
• Medium: 23
• High: 20
• VeryHigh: 18

pub fn to_preset(self) -> QualityPreset

Converts quality mode to a preset.

pub fn speed_factor(self) -> f64

Estimates encoding speed factor relative to real-time.

Returns

Approximate speed factor:

• Low: 5.0x (encodes 5x faster than real-time)
• Medium: 1.5x
• High: 0.5x
• VeryHigh: 0.2x

Trait Implementations

impl Clone for QualityMode

fn clone(&self) -> QualityMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QualityMode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for QualityMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for QualityMode

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

impl Serialize for QualityMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
