#aspect_ratio ⇒ String
To better control resolution and aspect ratio of output videos, we
recommend that you use the values MaxWidth
, MaxHeight
,
SizingPolicy
, PaddingPolicy
, and DisplayAspectRatio
instead of
Resolution
and AspectRatio
. The two groups of settings are
mutually exclusive. Do not use them together.
The display aspect ratio of the video in the output file. Valid values include:
auto
, 1:1
, 4:3
, 3:2
, 16:9
If you specify auto
, Elastic Transcoder tries to preserve the
aspect ratio of the input file.
If you specify an aspect ratio for the output file that differs from aspect ratio of the input file, Elastic Transcoder adds pillarboxing (black bars on the sides) or letterboxing (black bars on the top and bottom) to maintain the aspect ratio of the active region of the video.

#codec_options ⇒ Hash<String,String>
Profile (H.264/VP8/VP9 Only)
The H.264 profile that you want to use for the output file. Elastic Transcoder supports the following profiles:
baseline
: The profile most commonly used for videoconferencing and for mobile applications.main
: The profile used for standard-definition digital TV broadcasts.high
: The profile used for high-definition digital TV broadcasts and for Blu-ray discs.
Level (H.264 Only)
The H.264 level that you want to use for the output file. Elastic Transcoder supports the following levels:
1
, 1b
, 1.1
, 1.2
, 1.3
, 2
, 2.1
, 2.2
, 3
, 3.1
,
3.2
, 4
, 4.1
MaxReferenceFrames (H.264 Only)
Applicable only when the value of Video:Codec is H.264. The maximum number of previously decoded frames to use as a reference for decoding future frames. Valid values are integers 0 through 16, but we recommend that you not use a value greater than the following:
Min(Floor(Maximum decoded picture buffer in macroblocks * 256 /
(Width in pixels * Height in pixels)), 16)
where Width in pixels and Height in pixels represent either
MaxWidth and MaxHeight, or Resolution. Maximum decoded picture
buffer in macroblocks depends on the value of the Level
object.
See the list below. (A macroblock is a block of pixels measuring
16x16.)
1 - 396
1b - 396
1.1 - 900
1.2 - 2376
1.3 - 2376
2 - 2376
2.1 - 4752
2.2 - 8100
3 - 8100
3.1 - 18000
3.2 - 20480
4 - 32768
4.1 - 32768
MaxBitRate (Optional, H.264/MPEG2/VP8/VP9 only)
The maximum number of bits per second in a video buffer; the size of
the buffer is specified by BufferSize
. Specify a value between 16
and 62,500. You can reduce the bandwidth required to stream a video
by reducing the maximum bit rate, but this also reduces the quality
of the video.
BufferSize (Optional, H.264/MPEG2/VP8/VP9 only)
The maximum number of bits in any x seconds of the output video.
This window is commonly 10 seconds, the standard segment duration
when you're using FMP4 or MPEG-TS for the container type of the
output video. Specify an integer greater than 0. If you specify
MaxBitRate
and omit BufferSize
, Elastic Transcoder sets
BufferSize
to 10 times the value of MaxBitRate
.
InterlacedMode (Optional, H.264/MPEG2 Only)
The interlace mode for the output video.
Interlaced video is used to double the perceived frame rate for a video by interlacing two fields (one field on every other line, the other field on the other lines) so that the human eye registers multiple pictures per frame. Interlacing reduces the bandwidth required for transmitting a video, but can result in blurred images and flickering.
Valid values include Progressive
(no interlacing, top to bottom),
TopFirst
(top field first), BottomFirst
(bottom field first),
and Auto
.
If InterlaceMode
is not specified, Elastic Transcoder uses
Progressive
for the output. If Auto
is specified, Elastic
Transcoder interlaces the output.
ColorSpaceConversionMode (Optional, H.264/MPEG2 Only)
The color space conversion Elastic Transcoder applies to the output
video. Color spaces are the algorithms used by the computer to store
information about how to render color. Bt.601
is the standard for
standard definition video, while Bt.709
is the standard for high
definition video.
Valid values include None
, Bt709toBt601
, Bt601toBt709
, and
Auto
.
If you chose Auto
for ColorSpaceConversionMode
and your output
is interlaced, your frame rate is one of 23.97
, 24
, 25
,
29.97
, 50
, or 60
, your SegmentDuration
is null, and you are
using one of the resolution changes from the list below, Elastic
Transcoder applies the following color space conversions:
Standard to HD, 720x480 to 1920x1080 - Elastic Transcoder applies
Bt601ToBt709
Standard to HD, 720x576 to 1920x1080 - Elastic Transcoder applies
Bt601ToBt709
HD to Standard, 1920x1080 to 720x480 - Elastic Transcoder applies
Bt709ToBt601
HD to Standard, 1920x1080 to 720x576 - Elastic Transcoder applies
Bt709ToBt601
ColorspaceConversionMode
Auto
mode in the future. All outputs in
a playlist must use the same ColorSpaceConversionMode
.
If you do not specify a ColorSpaceConversionMode
, Elastic
Transcoder does not change the color space of a file. If you are
unsure what ColorSpaceConversionMode
was applied to your output
file, you can check the AppliedColorSpaceConversion
parameter
included in your job response. If your job does not have an
AppliedColorSpaceConversion
in its response, no
ColorSpaceConversionMode
was applied.
ChromaSubsampling
The sampling pattern for the chroma (color) channels of the output
video. Valid values include yuv420p
and yuv422p
.
yuv420p
samples the chroma information of every other horizontal
and every other vertical line, yuv422p
samples the color
information of every horizontal line and every other vertical line.
LoopCount (Gif Only)
The number of times you want the output gif to loop. Valid values
include Infinite
and integers between 0
and 100
, inclusive.

#fixed_gop ⇒ String
Applicable only when the value of Video:Codec is one of H.264
,
MPEG2
, or VP8
.
Whether to use a fixed value for FixedGOP
. Valid values are true
and false
:
true
: Elastic Transcoder uses the value ofKeyframesMaxDist
for the distance between key frames (the number of frames in a group of pictures, or GOP).false
: The distance between key frames can vary.
FixedGOP
must be set to true
for fmp4
containers.

#frame_rate ⇒ String
The frames per second for the video stream in the output file. Valid values include:
auto
, 10
, 15
, 23.97
, 24
, 25
, 29.97
, 30
, 60
If you specify auto
, Elastic Transcoder uses the detected frame
rate of the input source. If you specify a frame rate, we recommend
that you perform the following calculation:
Frame rate = maximum recommended decoding speed in luma
samples/second / (width in pixels * height in pixels)
where:
width in pixels and height in pixels represent the Resolution of the output video.
maximum recommended decoding speed in Luma samples/second is less than or equal to the maximum value listed in the following table, based on the value that you specified for Level.
The maximum recommended decoding speed in Luma samples/second for each level is described in the following list (Level - Decoding speed):
1 - 380160
1b - 380160
1.1 - 76800
1.2 - 1536000
1.3 - 3041280
2 - 3041280
2.1 - 5068800
2.2 - 5184000

# File 'gems/aws-sdk-elastictranscoder/lib/aws-sdk-elastictranscoder/types.rb', line 4226 class VideoParameters < Struct.new( :codec, :codec_options, :keyframes_max_dist, :fixed_gop, :bit_rate, :frame_rate, :max_frame_rate, :resolution, :aspect_ratio, :max_width, :max_height, :display_aspect_ratio, :sizing_policy, :padding_policy, :watermarks) SENSITIVE = [] include Aws::Structure end |
#keyframes_max_dist ⇒ String
Applicable only when the value of Video:Codec is one of H.264
,
MPEG2
, or VP8
.
The maximum number of frames between key frames. Key frames are fully encoded frames; the frames between key frames are encoded based, in part, on the content of the key frames. The value is an integer formatted as a string; valid values are between 1 (every frame is a key frame) and 100000, inclusive. A higher value results in higher compression but may also discernibly decrease video quality.
For Smooth
outputs, the FrameRate
must have a constant ratio to
the KeyframesMaxDist
. This allows Smooth
playlists to switch
between different quality levels while the file is being played.
For example, an input file can have a FrameRate
of 30 with a
KeyframesMaxDist
of 90. The output file then needs to have a ratio
of 1:3. Valid outputs would have FrameRate
of 30, 25, and 10, and
KeyframesMaxDist
of 90, 75, and 30, respectively.
Alternately, this can be achieved by setting FrameRate
to auto and
having the same values for MaxFrameRate
and KeyframesMaxDist
.

#max_frame_rate ⇒ String
If you specify auto
for FrameRate
, Elastic Transcoder uses the
frame rate of the input video for the frame rate of the output
video. Specify the maximum frame rate that you want Elastic
Transcoder to use when the frame rate of the input video is greater
than the desired maximum frame rate of the output video. Valid
values include: 10

#padding_policy ⇒ String
When you set PaddingPolicy
to Pad
, Elastic Transcoder may add
black bars to the top and bottom and/or left and right sides of the
output video to make the total size of the output video match the
values that you specified for MaxWidth
and MaxHeight
.

#resolution ⇒ String
To better control resolution and aspect ratio of output videos, we
recommend that you use the values MaxWidth
, MaxHeight
,
SizingPolicy
, PaddingPolicy
, and DisplayAspectRatio
instead of
Resolution
and AspectRatio
. The two groups of settings are
mutually exclusive. Do not use them together.
The width and height of the video in the output file, in pixels.
Valid values are auto
and width x height:
auto
: Elastic Transcoder attempts to preserve the width and height of the input file, subject to the following rules.width x height
: The width and height of the output video in pixels.
Note the following about specifying the width and height:
The width must be an even integer between 128 and 4096, inclusive.
The height must be an even integer between 96 and 3072, inclusive.
If you specify a resolution that is less than the resolution of the input file, Elastic Transcoder rescales the output file to the lower resolution.
If you specify a resolution that is greater than the resolution of the input file, Elastic Transcoder rescales the output to the higher resolution.
We recommend that you specify a resolution for which the product of width and height is less than or equal to the applicable value in the following list (List - Max width x height value):
1 - 25344
1b - 25344
1.1 - 101376

#sizing_policy ⇒ String
Specify one of the following values to control scaling of the output video:
Fit
: Elastic Transcoder scales the output video so it matches the value that you specified in eitherMaxWidth
orMaxHeight
without exceeding the other value.Fill
: Elastic Transcoder scales the output video so it matches the value that you specified in eitherMaxWidth
orMaxHeight
and matches or exceeds the other value. Elastic Transcoder centers the output video and then crops it in the dimension (if any) that exceeds the maximum value.Stretch
: Elastic Transcoder stretches the output video to match the values that you specified forMaxWidth
andMaxHeight
. If the relative proportions of the input video and the output video are different, the output video will be distorted.Keep
: Elastic Transcoder does not scale the output video. If either dimension of the input video exceeds the values that you specified forMaxWidth
andMaxHeight
, Elastic Transcoder crops the output video.ShrinkToFit
: Elastic Transcoder scales the output video down so that its dimensions match the values that you specified for at least one ofMaxWidth
andMaxHeight
without exceeding either value. If you specify this option, Elastic Transcoder does not scale the video up.ShrinkToFill
: Elastic Transcoder scales the output video down so that its dimensions match the values that you specified for at least one ofMaxWidth

#watermarks ⇒ Array<Types::PresetWatermark>
Settings for the size, location, and opacity of graphics that you want Elastic Transcoder to overlay over videos that are transcoded using this preset. You can specify settings for up to four watermarks. Watermarks appear in the specified size and location, and with the specified opacity for the duration of the transcoded video.
Watermarks can be in .png or .jpg format. If you want to display a watermark that is not rectangular, use the .png format, which supports transparency.
When you create a job that uses this preset, you specify the .png or .jpg graphics that you want Elastic Transcoder to include in the transcoded videos. You can specify fewer graphics in the job than you specify watermark settings in the preset, which allows you to use the same preset for up to four watermarks that have different dimensions.
