I have been having over and over the same problem: inability to easily download in highest possible quality videos from at least YouTube
I thought that http://www.clipconverter.cc was the answer, but aside from recently self-implemented restrictions, it found out that is has the same flaw as other sites and plugins for Firefox that I've recently tried: it is able to get a video in the highest resolution, but downloads it with a lesser audio quality that there is. And I know this because I can with compare in spectrogam a downloaded file with a file containing a what-you-hear recording of the same content played from the source location [as it turns out, what I hear on YouTube has usually 20 kHz, and various plugins save files with only 16kHz]
Does anyone know a free of charge site, plugin [not necessarily for Firefox] or software [for Windows 7 x64], than can download videos with both best available video and audio quality; without additional transcoding?
[I have a tested and working solution: <a href="http://www.tecmint.com/install-youtube-dl-command-line-video-download-tool" target="_blank">http://www.tecmint.com/install-youtube-dl-...-download-tool/</a>; but it requires way too many steps / manuall work and automating them with a script is way beyond my capabilities and thus I will be using it only as a last resort for some single problematic cases]
