20 years ago — yes, two zero — I worked out a way to (sort of) track a subject in an early Sony Vegas and I used it constantly as a result. The handful of people who saw it at the time were really impressed, but the truth was, it was pretty easy, albeit a little time-consuming. Even back then, with software far simpler than today, you could find little gems of features and settings, buried in menus or requiring some intimate workflow.
With today's editing suites — particularly Adobe's which have been iterated on for several decades — there is an absurd level of depth. As with Adobe Photoshop, when I see videos professing to teach me some "hack" or "trick", I'll watch it. I've been using Photoshop for over two decades and I feel nowhere near an "expert" in it. These tricks are not just throwaway features you save in a folder for some unlikely scenario that never happens either. Many can fundamentally improve your workflow and as a goblin once told me, "time is money, friend."
