VideoQuality

enum VideoQuality : Enum<VideoQuality> (source)

How much bitrate an export spends on its video, relative to its frame size, codec and frame rate.

Each tier resolves to one bitrate at plan time, the same on every backend, and that is what OutputFormat.bitrate reports. The reference rate is 3 Mbps for a 1080p H.264 frame at 30 fps, and it scales with the frame's pixel count, the codec and any frame rate above 30. A transcode that names neither a bitrate nor a tier runs at High.

Entries

VeryLow

The lowest tier, at 0.3 times the reference rate for a frame. It gives the smallest file.

Low

The second tier, at about 0.57 times the reference rate for a frame.

Medium

The middle tier, at about 1.08 times the reference rate for a frame.

High

The fourth tier, at about 2.04 times the reference rate for a frame. A transcode that names no bitrate runs at this tier.

VeryHigh

The highest tier, at about 3.86 times the reference rate for a frame. It gives the largest file.

Functions

valueOf

fun valueOf(value: String): VideoQuality

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

values
