class Aws::MediaConvert::Types::Vp8Settings

Required when you set (Codec) under (VideoDescription)>(CodecSettings) to the value VP8.

@note When making an API call, you may pass Vp8Settings

data as a hash:

      framerate_conversion_algorithm: "DUPLICATE_DROP", # accepts DUPLICATE_DROP, INTERPOLATE, FRAMEFORMER
      framerate_denominator: 1,

      rate_control_mode: "VBR", # accepts VBR
    }

@!attribute [rw] bitrate

Target bitrate in bits/second. For example, enter five megabits per
second as 5000000.
@return [Integer]

@!attribute [rw] framerate_control

If you are using the console, use the Framerate setting to specify
the frame rate for this output. If you want to keep the same frame
rate as the input video, choose Follow source. If you want to do
frame rate conversion, choose a frame rate from the dropdown list or
choose Custom. The framerates shown in the dropdown list are decimal
approximations of fractions. If you choose Custom, specify your
frame rate as a fraction. If you are creating your transcoding job
specification as a JSON file without the console, use
FramerateControl to specify which value the service uses for the
frame rate for this output. Choose INITIALIZE\_FROM\_SOURCE if you
want the service to use the frame rate from the input. Choose
SPECIFIED if you want the service to use the frame rate you specify
in the settings FramerateNumerator and FramerateDenominator.
@return [String]

@!attribute [rw] framerate_conversion_algorithm

Choose the method that you want MediaConvert to use when increasing
or decreasing the frame rate. We recommend using drop duplicate
(DUPLICATE\_DROP) for numerically simple conversions, such as 60 fps
to 30 fps. For numerically complex conversions, you can use
interpolate (INTERPOLATE) to avoid stutter. This results in a smooth
picture, but might introduce undesirable video artifacts. For
complex frame rate conversions, especially if your source video has
already been converted from its original cadence, use FrameFormer
(FRAMEFORMER) to do motion-compensated interpolation. FrameFormer
chooses the best conversion method frame by frame. Note that using
FrameFormer increases the transcoding time and incurs a significant
add-on cost.
@return [String]

@!attribute [rw] framerate_denominator

When you use the API for transcode jobs that use frame rate
conversion, specify the frame rate as a fraction. For example, 24000
/ 1001 = 23.976 fps. Use FramerateDenominator to specify the
denominator of this fraction. In this example, use 1001 for the
value of FramerateDenominator. When you use the console for
transcode jobs that use frame rate conversion, provide the value as
a decimal number for Framerate. In this example, specify 23.976.
@return [Integer]

@!attribute [rw] framerate_numerator

When you use the API for transcode jobs that use frame rate
conversion, specify the frame rate as a fraction. For example, 24000
/ 1001 = 23.976 fps. Use FramerateNumerator to specify the numerator
of this fraction. In this example, use 24000 for the value of
FramerateNumerator. When you use the console for transcode jobs that
use frame rate conversion, provide the value as a decimal number for
Framerate. In this example, specify 23.976.
@return [Integer]

@!attribute [rw] gop_size

GOP Length (keyframe interval) in frames. Must be greater than zero.
@return [Float]

@!attribute [rw] hrd_buffer_size

Optional. Size of buffer (HRD buffer model) in bits. For example,
enter five megabits as 5000000.
@return [Integer]

@!attribute [rw] max_bitrate

Ignore this setting unless you set qualityTuningLevel to
MULTI\_PASS. Optional. Specify the maximum bitrate in bits/second.
For example, enter five megabits per second as 5000000. The default
behavior uses twice the target bitrate as the maximum bitrate.
@return [Integer]

@!attribute [rw] par_control

Optional. Specify how the service determines the pixel aspect ratio
(PAR) for this output. The default behavior, Follow source
(INITIALIZE\_FROM\_SOURCE), uses the PAR from your input video for
your output. To specify a different PAR in the console, choose any
value other than Follow source. To specify a different PAR by
editing the JSON job specification, choose SPECIFIED. When you
choose SPECIFIED for this setting, you must also specify values for
the parNumerator and parDenominator settings.
@return [String]

@!attribute [rw] par_denominator

Required when you set Pixel aspect ratio (parControl) to SPECIFIED.
On the console, this corresponds to any value other than Follow
source. When you specify an output pixel aspect ratio (PAR) that is
different from your input video PAR, provide your output PAR as a
ratio. For example, for D1/DV NTSC widescreen, you would specify the
ratio 40:33. In this example, the value for parDenominator is 33.
@return [Integer]

@!attribute [rw] par_numerator

Required when you set Pixel aspect ratio (parControl) to SPECIFIED.
On the console, this corresponds to any value other than Follow
source. When you specify an output pixel aspect ratio (PAR) that is
different from your input video PAR, provide your output PAR as a
ratio. For example, for D1/DV NTSC widescreen, you would specify the
ratio 40:33. In this example, the value for parNumerator is 40.
@return [Integer]

@!attribute [rw] quality_tuning_level

Optional. Use Quality tuning level (qualityTuningLevel) to choose
how you want to trade off encoding speed for output video quality.
The default behavior is faster, lower quality, multi-pass encoding.
@return [String]

@!attribute [rw] rate_control_mode

With the VP8 codec, you can use only the variable bitrate (VBR) rate
control mode.
@return [String]
