Enum Quality 

pub enum Quality {
    UltraFast,
    VeryFast,
    Fast,
    Basic,
    Slow,
    VerySlow,
}

Universal quality preset all encoders understand.

Presets trade encode speed for output quality, from fastest/lowest to slowest/highest. Each encoder maps these onto its own native effort levels.

Variants

UltraFast

Fastest encode, lowest quality.

VeryFast

Very fast encode, low quality.

Fast

Fast encode, moderate quality.

Basic

Balanced speed/quality — the default.

Slow

Slow encode, high quality.

VerySlow

Slowest encode, highest quality.
