Technical: Editing
On November 4, 2017 we posted "The Most Comprehensive Editing Tutorial Ever" and damn it, 17 months later, I truly believe it's still the MOST comprehensive editing tutorial EVER. Yes, that video is about Adobe Premiere. No, you do not need to use Adobe Premiere to learn from it.
Setting up your edit
Let's talk about workflows and organization. Don't be the one person who stores everything on your desktop. Stay organized. As an editor, you're going to find yourself collaborating more and more once you improve. When I shoot a video, I send the footage to my editor, but then after a few days, he sends his edit (files, folders, and project files) back to me so I can color grade it. Even when I know I'm not working with multiple editors, I still stay organized for my own sanity. I make a lot of videos so folder structure is important to me. I use the roughly same format for every video. I also use a handy app called Post Haste to help me create empty folder structures in one simple click.

Organization is key. You can see an example of one of my older folder structures to the right. I don't have a "Projects" folder like most people do, that's because I work with FCPX. The way Premiere saves project files is way different than FCPX. If I use any Adobe CC apps, you'll find me making an "Adobe CC" folder with sub folders for each app I use. You'll also notice that all editors use a different structure. Find one that works for you. There's no right or wrong way, so long as you're staying organized in a way that makes sense for you.
In the editing world, you're going to hear the word "workflow" a ton. A Workflow is basically the steps you take to edit a video. From ingest to export. Ingest, is simply importing footage from the camera's cards to your computer. From ingest, you may encode your footage and audio to some kind of sync software, or maybe one that re-encodes audio time code into actual time code. From there you may work exclusively in one editing software, or you may use multiple depending on the needs of the video. For example: I edit in Final Cut but if I need to do heavy color correction, I'll export my timeline (XML) to Davinci Resolve and color correct/grade it there. The I export. Each step is a part of my work flow. I talk a little bit about workflows in my "Which Editing Software Should I Use?" Video. Below are some supplemental videos to watch as well.
