NAME
Paws::MediaConvert::Mpeg2Settings
USAGE
This class represents one of two things:
Arguments in a call to a service
Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.
As an example, if Att1 is expected to be a Paws::MediaConvert::Mpeg2Settings object:
$service_obj->Method(Att1 => { AdaptiveQuantization => $value, ..., TemporalAdaptiveQuantization => $value });Results returned from an API call
Use accessors for each attribute. If Att1 is expected to be an Paws::MediaConvert::Mpeg2Settings object:
$result = $service_obj->Method(...);
$result->Att1->AdaptiveQuantizationDESCRIPTION
Required when you set (Codec) under (VideoDescription)>(CodecSettings) to the value MPEG2.
ATTRIBUTES
AdaptiveQuantization => Str
Adaptive quantization. Allows intra-frame quantizers to vary to improve visual quality.
Bitrate => Int
Specify the average bitrate in bits per second. Required for VBR and CBR. For MS Smooth outputs, bitrates must be unique when rounded down to the nearest multiple of 1000.
CodecLevel => Str
Use Level (Mpeg2CodecLevel) to set the MPEG-2 level for the video output.
CodecProfile => Str
Use Profile (Mpeg2CodecProfile) to set the MPEG-2 profile for the video output.
DynamicSubGop => Str
Choose Adaptive to improve subjective video quality for high-motion content. This will cause the service to use fewer B-frames (which infer information based on other frames) for high-motion portions of the video and more B-frames for low-motion portions. The maximum number of B-frames is limited by the value you provide for the setting B frames between reference frames (numberBFramesBetweenReferenceFrames).
FramerateControl => Str
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 sepecification 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.
FramerateConversionAlgorithm => Str
When set to INTERPOLATE, produces smoother motion during frame rate conversion.
FramerateDenominator => Int
Frame rate denominator.
FramerateNumerator => Int
Frame rate numerator - frame rate is a fraction, e.g. 24000 / 1001 = 23.976 fps.
GopClosedCadence => Int
Frequency of closed GOPs. In streaming applications, it is recommended that this be set to 1 so a decoder joining mid-stream will receive an IDR frame as quickly as possible. Setting this value to 0 will break output segmenting.
GopSize => Num
GOP Length (keyframe interval) in frames or seconds. Must be greater than zero.
GopSizeUnits => Str
Indicates if the GOP Size in MPEG2 is specified in frames or seconds. If seconds the system will convert the GOP Size into a frame count at run time.
HrdBufferInitialFillPercentage => Int
Percentage of the buffer that should initially be filled (HRD buffer model).
HrdBufferSize => Int
Size of buffer (HRD buffer model) in bits. For example, enter five megabits as 5000000.
InterlaceMode => Str
Use Interlace mode (InterlaceMode) to choose the scan line type for the output. * Top Field First (TOP_FIELD) and Bottom Field First (BOTTOM_FIELD) produce interlaced output with the entire output having the same field polarity (top or bottom first). * Follow, Default Top (FOLLOW_TOP_FIELD) and Follow, Default Bottom (FOLLOW_BOTTOM_FIELD) use the same field polarity as the source. Therefore, behavior depends on the input scan type. - If the source is interlaced, the output will be interlaced with the same polarity as the source (it will follow the source). The output could therefore be a mix of "top field first" and "bottom field first". - If the source is progressive, the output will be interlaced with "top field first" or "bottom field first" polarity, depending on which of the Follow options you chose.
IntraDcPrecision => Str
Use Intra DC precision (Mpeg2IntraDcPrecision) to set quantization precision for intra-block DC coefficients. If you choose the value auto, the service will automatically select the precision based on the per-frame compression ratio.
MaxBitrate => Int
Maximum bitrate in bits/second. For example, enter five megabits per second as 5000000.
MinIInterval => Int
Enforces separation between repeated (cadence) I-frames and I-frames inserted by Scene Change Detection. If a scene change I-frame is within I-interval frames of a cadence I-frame, the GOP is shrunk and/or stretched to the scene change I-frame. GOP stretch requires enabling lookahead as well as setting I-interval. The normal cadence resumes for the next GOP. This setting is only used when Scene Change Detect is enabled. Note: Maximum GOP stretch = GOP size + Min-I-interval - 1
NumberBFramesBetweenReferenceFrames => Int
Number of B-frames between reference frames.
ParControl => Str
Using the API, enable ParFollowSource if you want the service to use the pixel aspect ratio from the input. Using the console, do this by choosing Follow source for Pixel aspect ratio.
ParDenominator => Int
Pixel Aspect Ratio denominator.
ParNumerator => Int
Pixel Aspect Ratio numerator.
QualityTuningLevel => Str
Use Quality tuning level (Mpeg2QualityTuningLevel) to specifiy whether to use single-pass or multipass video encoding.
RateControlMode => Str
Use Rate control mode (Mpeg2RateControlMode) to specifiy whether the bitrate is variable (vbr) or constant (cbr).
SceneChangeDetect => Str
Enable this setting to insert I-frames at scene changes that the service automatically detects. This improves video quality and is enabled by default.
SlowPal => Str
Enables Slow PAL rate conversion. 23.976fps and 24fps input is relabeled as 25fps, and audio is sped up correspondingly.
Softness => Int
Softness. Selects quantizer matrix, larger values reduce high-frequency content in the encoded image.
SpatialAdaptiveQuantization => Str
Adjust quantization within each frame based on spatial variation of content complexity.
Syntax => Str
Produces a Type D-10 compatible bitstream (SMPTE 356M-2001).
Telecine => Str
Only use Telecine (Mpeg2Telecine) when you set Framerate (Framerate) to 29.970. Set Telecine (Mpeg2Telecine) to Hard (hard) to produce a 29.97i output from a 23.976 input. Set it to Soft (soft) to produce 23.976 output and leave converstion to the player.
TemporalAdaptiveQuantization => Str
Adjust quantization within each frame based on temporal variation of content complexity.
