// QTCompressionOptionsWindow is a simple class that demonstrates how easy it is to manage the preset QTCapture media

// compression options encapsulated in a QTCompressionOptions object.

// The QTCompressionOptions class represents a set of compression options for a particular type of media.

// QTCompressionOptions objects are used to describe compression options for different kinds of media.

// Compression options are created from presets keyed by a named identifier such as @"QTCompressionOptions120SizeH264Video"

// or @"QTCompressionOptionsHighQualityAACAudio" but may also be returned dynamically using the

// +compressionOptionsIdentifiersForMediaType method.
