Here's a list of equipment I set up for my blog casting studio. You may need more or less, depending on what you're trying to accomplish. I take some of this equipment on location to produce other segments.
You'll need some cables, a few grip stands, and lots of subject matter. However, the above list covers the major components that enable me to produce my videos for my YouTube channel "lenswork4" and my video blog cast show, "Doin' Time With Dan." I also use it to make video reviews for Amazon. To save money, you can substitute a less expensive camera because video watched over the internet is degraded. I went with the better camera because some of my productions are used on cable television. Best of luck!
