https://www.youtube.com/watch?v=5T_ePuuIsOw - Hey guys. Now before anybody rips on me I don't like Yung Lean but I do have an interest in this editing. Specifically, I wanted to know how the quick zooms and quick pans are done, I've tried in AE before but had no luck, so what better place to come but the forums. Thanks guys!
No idea. Can't see the video due to audio copyright restrictions. Beyond that saying "I've tried in AE before but had no luck" is not really useful without showing and explaining what you have so far...
A lot of those are done in camera. Some could be done be animating a camera or scale with motion blur. The problem with pushing in or snapping out of existing video is that any footage over about 125% scale is going to start falling apart. If you need that kind of look then shoot it in camera or shoot 4K or bigger and produce in HD.
