/AWS1/CL_MDCVP8SETTINGS¶
Required when you set Codec to the value VP8.
CONSTRUCTOR¶
IMPORTING¶
Optional arguments:¶
IV_BITRATE TYPE /AWS1/MDC__INTEGERMIN1000MAX01 /AWS1/MDC__INTEGERMIN1000MAX01¶
Target bitrate in bits/second. For example, enter five megabits per second as 5000000.
IV_FRAMERATECONTROL TYPE /AWS1/MDCVP8FRAMERATECONTROL /AWS1/MDCVP8FRAMERATECONTROL¶
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.
IV_FRAMERATECONVERSIONALG TYPE /AWS1/MDCVP8FRAMERATECONVRSALG /AWS1/MDCVP8FRAMERATECONVRSALG¶
Choose the method that you want MediaConvert to use when increasing or decreasing the frame rate. For numerically simple conversions, such as 60 fps to 30 fps: We recommend that you keep the default value, Drop duplicate. For numerically complex conversions, to avoid stutter: Choose Interpolate. 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: Choose FrameFormer to do motion-compensated interpolation. FrameFormer uses the best conversion method frame by frame. Note that using FrameFormer increases the transcoding time and incurs a significant add-on cost. When you choose FrameFormer, your input video resolution must be at least 128x96.
IV_FRAMERATEDENOMINATOR TYPE /AWS1/MDC__INTEGERMIN1MAX21400 /AWS1/MDC__INTEGERMIN1MAX21400¶
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.
IV_FRAMERATENUMERATOR TYPE /AWS1/MDC__INTEGERMIN1MAX21400 /AWS1/MDC__INTEGERMIN1MAX21400¶
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.
IV_GOPSIZE TYPE /AWS1/RT_DOUBLE_AS_STRING /AWS1/RT_DOUBLE_AS_STRING¶

IV_MAXBITRATE TYPE /AWS1/MDC__INTEGERMIN1000MAX01 /AWS1/MDC__INTEGERMIN1000MAX01¶
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.
IV_PARCONTROL TYPE /AWS1/MDCVP8PARCONTROL /AWS1/MDCVP8PARCONTROL¶
Optional. Specify how the service determines the pixel aspect ratio (PAR) for this output. The default behavior, Follow 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. When you choose SPECIFIED for this setting, you must also specify values for the parNumerator and parDenominator settings.
IV_PARDENOMINATOR TYPE /AWS1/MDC__INTEGERMIN1MAX21400 /AWS1/MDC__INTEGERMIN1MAX21400¶
Required when you set Pixel aspect ratio 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.
IV_PARNUMERATOR TYPE /AWS1/MDC__INTEGERMIN1MAX21400 /AWS1/MDC__INTEGERMIN1MAX21400¶
Required when you set Pixel aspect ratio 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.
IV_QUALITYTUNINGLEVEL TYPE /AWS1/MDCVP8QUALITYTUNINGLEVEL /AWS1/MDCVP8QUALITYTUNINGLEVEL¶
Optional. Use Quality tuning level to choose how you want to trade off encoding speed for output video quality. The default behavior is faster, lower quality, multi-pass encoding.
IV_RATECONTROLMODE TYPE /AWS1/MDCVP8RATECONTROLMODE /AWS1/MDCVP8RATECONTROLMODE¶
With the VP8 codec, you can use only the variable bitrate (VBR) rate control mode.
