Higher Quality HIDDEN YouTube Audio
I recently realised that many YouTube Music Videos have a hidden high quality audio track, and not just the crappy typical 128kbps .aac audio that we all hear.
For something to do , I had saved a YouTube video from Dua Lipa with 128kbps .aac Audio, and from a couple of nights earlier on RAGE (ABC HDTV) where they transmit higher quality audio.
I Demultiplexed them both with my Video S/W, (the Video and audio of both) with the idea of giving the higher quality looking YouTube video the better sounding Audio as well .
With YouTube ,this gave me an X264 Video file that none of my S/W players will play, and the couple of MB .aac audio as a separate .aac Audio file.
However, when I opened this X264 video in TMPGEnc Video Mastering Works 5 ,it still showed it as having Audio, despite the file being smaller after the .aac audio was removed.
I then decided to convert the X264 file to BluRay format to see what came out.
The results are at the links below.
In many cases, the new audio may be out of Sync with the Video, (or different ?) however, with Carly Simon-You're So Vain,for example,it was correct.
However, if you just wish to obtain higher quality audio, as with some Classical Music performances, this won't be a problem.
Many members will have heard the YouTube performance from SNL by Adele, so I have attached a comparison between both lots of Audio, although the Audio is WAY out of Sync with the Video in this example.
