For information…

RocketJump’s ‘How Star Wars was saved in the edit’ video can be seen here:-

https://www.youtube.com/watch?v=GFMyMxMYDNk - an 18 minute long video, from the erm… Rocketjump youtube channel.

The blurb for the video: ‘‘A video essay exploring how Star Wars’ editors recut and rearranged Star Wars: A New Hope to create the cinematic classic it became.’

I haven’t seen the 2 hour long video linked in the OP by G&G-Fan - though I am not sure how a video (in this context) can be “Literally a Lie”. Literally… 😉
