aspectRatio property
The aspect ratio of the input file. If you want Elastic Transcoder to
automatically detect the aspect ratio of the input file, specify
auto. If you want to specify the aspect ratio for the output
file, enter one of the following values:
1:1, 4:3, 3:2, 16:9
If you specify a value other than auto, Elastic Transcoder
disables automatic detection of the aspect ratio.
Implementation
final String? aspectRatio;
