	Compression options identifiers:
	
	A QTCompressionOptions object can be created with any of the following identifiers, each representing a set of options that determine how media will be compressed. 
 
	These compression options are appropriate for high quality intermediate video that requires further processing.
		@"QTCompressionOptionsLosslessAnimationVideo";
		@"QTCompressionOptionsJPEGVideo";
		@"QTCompressionOptionsLosslessAppleIntermediateVideo";		// Not available in 64-bit

	These compression options are appropriate for medium and low quality video that will be used for delivery to destinations such as the internet.
		@"QTCompressionOptions120SizeH264Video";
		@"QTCompressionOptions240SizeH264Video";
		@"QTCompressionOptionsSD480SizeH264Video";
		@"QTCompressionOptionsHD720SizeH264Video";
		@"QTCompressionOptions120SizeMPEG4Video";		// Not available in 64-bit
		@"QTCompressionOptions240SizeMPEG4Video";		// Not available in 64-bit
		@"QTCompressionOptionsSD480SizeMPEG4Video";		// Not available in 64-bit
	
	This compression option is appropriate for lossless audio that requires further processing, or is intended for high fidelity destinations.
		@"QTCompressionOptionsLosslessALACAudio";
 
	These compression options are appropriate for audio delivered with lossy compression.
		@"QTCompressionOptionsHighQualityAACAudio";		// For music and other high quality audio
		@"QTCompressionOptionsVoiceQualityAACAudio";	// For voice recordings
