VideoParameters
The VideoParameters
structure.
Types
Properties
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 bit rate of the video stream in the output file, in kilobits/second. Valid values depend on the values of Level
and Profile
. If you specify auto
, Elastic Transcoder uses the detected bit rate of the input source. If you specify a value other than auto
, we recommend that you specify a value less than or equal to the maximum H.264-compliant value listed for your level and profile:
Profile (H.264/VP8/VP9 Only)
The value that Elastic Transcoder adds to the metadata in the output file.
Applicable only when the value of Video:Codec is one of H.264
, MPEG2
, or VP8
.
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
, 15
, 23.97
, 24
, 25
, 29.97
, 30
, 60
.
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
.

Specify one of the following values to control scaling of the output video:
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.
