Properties

aspectRatio → String?

auto, 1:1, 4:3, 3:2, 16:9

final

bitRate → String?

The bit rate of the video stream in the output file, in kilobits/second. Valid values depend on the values of Level and Profile. If you specify auto, Elastic Transcoder uses the detected bit rate of the input source. If you specify a value other than auto, we recommend that you specify a value less than or equal to the maximum H.264-compliant value listed for your level and profile:

final

codec → String?

The video codec for the output file. Valid values include gif, H.264, mpeg2, vp8, and vp9. You can only specify vp8 and vp9 when the container type is webm, gif when the container type is gif, and mpeg2 when the container type is mpg.

final

codecOptions → Map<String, String>?

Profile (H.264/VP8/VP9 Only)

final

displayAspectRatio → String?

The value that Elastic Transcoder adds to the metadata in the output file.

final

fixedGOP → String?

Applicable only when the value of Video:Codec is one of H.264, MPEG2, or VP8.

final

frameRate → String?

The frames per second for the video stream in the output file. Valid values include:

final

hashCode → int

The hash code for this object.

no setter, inherited

keyframesMaxDist → String?

Applicable only when the value of Video:Codec is one of H.264, MPEG2, or VP8.

final

maxFrameRate → String?

If you specify auto for FrameRate, Elastic Transcoder uses the frame rate of the input video for the frame rate of the output video. Specify the maximum frame rate that you want Elastic Transcoder to use when the frame rate of the input video is greater than the desired maximum frame rate of the output video. Valid values include: 10, 15, 23.97, 24, 25, 29.97, 30, 60.

final

maxHeight → String?

The maximum height of the output video in pixels. If you specify auto, Elastic Transcoder uses 1080 (Full HD) as the default value. If you specify a numeric value, enter an even integer between 96 and 3072.

final

maxWidth → String?

The maximum width of the output video in pixels. If you specify auto, Elastic Transcoder uses 1920 (Full HD) as the default value. If you specify a numeric value, enter an even integer between 128 and 4096.

final

paddingPolicy → String?

When you set PaddingPolicy to Pad, Elastic Transcoder may add black bars to the top and bottom and/or left and right sides of the output video to make the total size of the output video match the values that you specified for MaxWidth and MaxHeight.

final

resolution → String?

auto

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sizingPolicy → String?

Specify one of the following values to control scaling of the output video:

final

watermarks → List<PresetWatermark>?

Settings for the size, location, and opacity of graphics that you want Elastic Transcoder to overlay over videos that are transcoded using this preset. You can specify settings for up to four watermarks. Watermarks appear in the specified size and location, and with the specified opacity for the duration of the transcoded video.

final

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
