videoQC viewing modes

videoQC includes a full reference analysis and and viewing system.  Two files can be loaded into the comparison dialog, and they can be played back together in a variety of ways, as well as having PSNR, SSIM and MS-SSIM comparisons charted between them. The viewing modes are perfect for comparing for example, a high resolution source file and a compressed version of the same file to determine whether the compressed file is of an acceptable quality.
