Sorry for the late reply. I injured my back months ago so I can't sit at a computer, and typing this one handed on mobile was daunting. I agree with the Kurzgesagt suggestion and I'll check those others.
EducativeD4DariousAn entertaining channel about film-making where he talks about screen-writing, cinematography and his experience working on films. Very informative yet easy to digest in a humourous and energetic format. Highly recommended.
Jeremy JahnsFunny and entertaining movie reviews that are concise and give a brief overview, which can be preferable to drawn out in-depth critiques at times.
AlanBeckerTutorialsAnimation tutorials from the animator of Animator vs Animation. Highly recommended to
anyone studying animation due to high production quality and many animation examples. His 12 Principles of Animation series is essentially the guide in animated form. Ridiculously good.
AnimationLg59Pivot animator who uploads regularly and his animations are awesome. Loads of Pivot tutorials.
PivotDBSuperZAnother Pivot animator who makes amazing full-body DBZ Pivots.
Michael CusackZany, out of this world, hilarious animations. He still animates regularly and his Damo and Darren series is an uncanny representation of Australia.
ExplosmEntertainmentProfessional and funny animations 3 times a week from the makers of Cyanide and Happiness. The weekly C&H is always good.
NewgroundsIt's Newgrounds on YouTube and they've been uploading weekly the past 4 months.
StickPage StudiosStick-figure centric, high quality and they don't upload a ridiculous amount which puts me off Hyun's Dojo at times.
Misc.brusspupMind-blowing optical illusions.
Peter SerafinowiczDonald Trump... With a sassy voice over. :p
The Slow Mo GuysEverything awesome. Even better in slow motion.
