What really helped me when I first started getting into VFX was really learning the basic concepts. Understanding why and how compositing, particles, motion tracking, and 3D models worked gave me a great foundation that helped me in the future. I wasn't too focused on specific software at the time. Like video editing, most VFX software work on the same principles; so once you can use one, it's easy to learn another. As far as a place to learn VFX, depending on the software and whether you're willing to spend money or not, the answer can vary. Video Copilot is always a good bet to get started with After Effects. There are also a bunch of YouTube channels like [Tolerated Cinematics](https://www.youtube.com/channel/UCNHY_bgEFYj3bNc5r6t1qNw) and [Lone Archer Films](https://www.youtube.com/user/lonearcherfilms) that do good stuff. As long as you know what you're looking for, most help is just a YouTube search away.
Thanks! I'll look them up!
