	//
	// 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

	// 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 either MaxWidth or MaxHeight without exceeding the
	//    other value.
	//
	//    * Fill: Elastic Transcoder scales the output video so it matches the value
	//    that you specified in either MaxWidth or MaxHeight 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 for MaxWidth and MaxHeight. 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 for
	//    MaxWidth and MaxHeight, 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 of
	//    MaxWidth and MaxHeight 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 of
	//    MaxWidth and MaxHeight without dropping below either value. If you specify
	//    this option, Elastic Transcoder does not scale the video up.
