How To Download Videos Using Chrome Developer Tools
Yes information technology is possible (perhaps not legal) but I desire to explain the technical part (annotation that I don't download videos from YouTube, there is no reason, as it is ever there on the cloud!).
YouTube transmits those streams in bytearrays and if you check for one clear url information technology doesn't exist. BUT: if y'all look in the dev tools and trace the network yous can find this url.
Take a look at this image: 
YouTube transmits in separate channels and at runtime puts it all together, using XMLHttpRequest to get the video and audio separately.
All calls which start with videoplayback? are about the video/audio streaming. The videoplayback? Ajax calls always come paired together: content-type= sound/* and content-type= video/* in some order.
You lot can individuate them from the headers (in the image it looks like content-type= video/* or content-type= audio/*)
To Become FULL Audio/VIDEO STREAM THE ONLY THING TO DO IS : Change the parameter RANGE.
The parameter RANGE specifies the segment of this content to stream (which is never usually the entire media since then it wouldn't be streaming, and to avoid downloads from nerd people)
Re-create the url which starts with videoplayback? (like is shown in the image). Find the parameter range= at the end of the querystring. The parameter range= is composed of a Kickoff and Stop (eg. range=18096-20098) which are separated by a "-".
Put 0 (zero) for START and a long number for END like 9999999999 (eg. range=0-999999999999). (Editor note, my guess is that these are the 'seconds' timestamps of the video)
After you take modified this URL, copy and paste information technology in a new tab in your browser and y'all can simply download the sound or video.
Get both streams and put them together in some audio/video editing software (eg. NUENDO)
Important: Don't change other parameters, every bit this is a self validating URL.
