NAME
Paws::MediaConvert::Xavc4kProfileSettings
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::Xavc4kProfileSettings object:
$service_obj->Method(Att1 => { BitrateClass => $value, ..., Slices => $value });Results returned from an API call
Use accessors for each attribute. If Att1 is expected to be an Paws::MediaConvert::Xavc4kProfileSettings object:
$result = $service_obj->Method(...);
$result->Att1->BitrateClassDESCRIPTION
Required when you set (Profile) under (VideoDescription)>(CodecSettings)>(XavcSettings) to the value XAVC_4K.
ATTRIBUTES
BitrateClass => Str
Specify the XAVC 4k (Long GOP) Bitrate Class to set the bitrate of your output. Outputs of the same class have similar image quality over the operating points that are valid for that class.
CodecProfile => Str
Specify the codec profile for this output. Choose High, 8-bit, 4:2:0 (HIGH) or High, 10-bit, 4:2:2 (HIGH_422). These profiles are specified in ITU-T H.264.
FlickerAdaptiveQuantization => Str
The best way to set up adaptive quantization is to keep the default value, Auto (AUTO), for the setting Adaptive quantization (XavcAdaptiveQuantization). When you do so, MediaConvert automatically applies the best types of quantization for your video content. Include this setting in your JSON job specification only when you choose to change the default value for Adaptive quantization. Enable this setting to have the encoder reduce I-frame pop. I-frame pop appears as a visual flicker that can arise when the encoder saves bits by copying some macroblocks many times from frame to frame, and then refreshes them at the I-frame. When you enable this setting, the encoder updates these macroblocks slightly more often to smooth out the flicker. This setting is disabled by default. Related setting: In addition to enabling this setting, you must also set Adaptive quantization (adaptiveQuantization) to a value other than Off (OFF) or Auto (AUTO). Use Adaptive quantization to adjust the degree of smoothing that Flicker adaptive quantization provides.
GopBReference => Str
Specify whether the encoder uses B-frames as reference frames for other pictures in the same GOP. Choose Allow (ENABLED) to allow the encoder to use B-frames as reference frames. Choose Don't allow (DISABLED) to prevent the encoder from using B-frames as reference frames.
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.
HrdBufferSize => Int
Specify the size of the buffer that MediaConvert uses in the HRD buffer model for this output. Specify this value in bits; for example, enter five megabits as 5000000. When you don't set this value, or you set it to zero, MediaConvert calculates the default by doubling the bitrate of this output point.
QualityTuningLevel => Str
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, single-pass encoding.
Slices => Int
Number of slices per picture. Must be less than or equal to the number of macroblock rows for progressive pictures, and less than or equal to half the number of macroblock rows for interlaced pictures.
