class Aws::MediaConvert::Types::Vc3Settings

Required when you set (Codec) under (VideoDescription)>(CodecSettings) to the value VC3

@note When making an API call, you may pass Vc3Settings

    }

@!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] interlace_mode

Optional. Choose the scan line type for this output. If you don't
specify a value, MediaConvert will create a progressive output.
@return [String]

@!attribute [rw] scan_type_conversion_mode

Use this setting for interlaced outputs, when your output frame rate
is half of your input frame rate. In this situation, choose
Optimized interlacing (INTERLACED\_OPTIMIZE) to create a better
quality interlaced output. In this case, each progressive frame from
the input corresponds to an interlaced field in the output. Keep the
default value, Basic interlacing (INTERLACED), for all other output
frame rates. With basic interlacing, MediaConvert performs any frame
rate conversion first and then interlaces the frames. When you
choose Optimized interlacing and you set your output frame rate to a
value that isn't suitable for optimized interlacing, MediaConvert
automatically falls back to basic interlacing. Required settings: To
use optimized interlacing, you must set Telecine (telecine) to None
(NONE) or Soft (SOFT). You can't use optimized interlacing for hard
telecine outputs. You must also set Interlace mode (interlaceMode)
to a value other than Progressive (PROGRESSIVE).
@return [String]

@!attribute [rw] slow_pal

Ignore this setting unless your input frame rate is 23.976 or 24
frames per second (fps). Enable slow PAL to create a 25 fps output
by relabeling the video frames and resampling your audio. Note that
enabling this setting will slightly reduce the duration of your
video. Related settings: You must also set Framerate to 25. In your
JSON job specification, set (framerateControl) to (SPECIFIED),
(framerateNumerator) to 25 and (framerateDenominator) to 1.
@return [String]

@!attribute [rw] telecine

When you do frame rate conversion from 23.976 frames per second
(fps) to 29.97 fps, and your output scan type is interlaced, you can
optionally enable hard telecine (HARD) to create a smoother picture.
When you keep the default value, None (NONE), MediaConvert does a
standard frame rate conversion to 29.97 without doing anything with
the field polarity to create a smoother picture.
@return [String]

@!attribute [rw] vc_3_class

Specify the VC3 class to choose the quality characteristics for this
output. VC3 class, together with the settings Framerate
(framerateNumerator and framerateDenominator) and Resolution (height
and width), determine your output bitrate. For example, say that
your video resolution is 1920x1080 and your framerate is 29.97. Then
Class 145 (CLASS\_145) gives you an output with a bitrate of
approximately 145 Mbps and Class 220 (CLASS\_220) gives you and
output with a bitrate of approximately 220 Mbps. VC3 class also
specifies the color bit depth of your output.
