That stands in contrast to the NIST's Cumulus Video Database clips, taken from the very same tapes but have instead both stereo channels working. See and hear for comparison to same video with non-enhanced broken audio: https://www.youtube.com/watch?v=vEamg438JBw MPEG-2 encoded video has been interlace deblocked, deinterlaced, decompressed and encoded again by a lossless video encoder. Resolution has been HQ dither upscaled to 1080p by fixing the original display aspect ratio (DAR) of 3:2 to 4:3 (conversion of non-square to square pixels), and video sharpened. Then video stream lossy compressed again by x.264 (2-pass encoding, variable video bit rate of 50 MBit/s) and muxed with audio stream in MP4 container format in MeGUI 2508, before upload on YouTube. As-released/corrupted AC3 audio stream decompressed and sent to lossless PCM audio codec/WAV format. Low volume normalized, only working left channel audio shift to the right channel, and stereo widening effect applied in Adobe Audition CS6, audio track saved again in PCM/WAV. Then losslessly compressed by Apple Lossless Audio Codec (ALAC) in MeGUI 2508, muxed there with video stream in MP4 container format before upload on YouTube.
