1. A Good Camera
I have two cameras I use when making YouTube videos. I have a Canon 70D and a Canon Rebel T3i. I generally use the 70D more often, just because it is the better camera of the two.
2. A Tripod
Invest in a tripod. Seriously. Shaky footage can take a video from amazing to "eh" really quickly. Now, if you're dong a vlog and need to be walking around a lot, that's a different story. I hardly ever use a tripod while vlogging.
3. A Subscription To a Royalty Free Music Site
Find a Royalty Free music site that creates music you like. The last thing you want is to be in trouble with copyright infringement.
4. A YouTube Channel
I MEAN... This one is really obvious. Make a channel, personalize it, and get started.
5. A Brand For Yourself
Check out my post about this!
6. Editing Software
Final Cut Pro and Premiere Pro are both really good, but iMovie works for beginners!
7. A Notebook
This is great for writing ideas in at home or on the go!
