Enum QualityLevel 

pub enum QualityLevel {
    VeryLow,
    Low,
    Medium,
    High,
    VeryHigh,
}

The five qualitative output levels.

The names are the browser adapter’s, so the engine and the adapter share one vocabulary for the concept. Their meaning is the engine’s: see the resolution functions beside this type.

Variants

VeryLow

Smallest output that is still watchable.

Low

Previews and proxies.

Medium

Streaming-sized delivery.

High

Delivery quality. The default.

VeryHigh

Close to visually transparent; mastering and re-encode sources.
