A note for FitKat: I hope you don't think all you need is the right camera to make professional quality videos.
The camera plays a part, but you also need proper video editing software and a computer powerful enough to run that software.
These are basic components, each requires accessories and add-ons (such as a tripod, as you've mentioned).
That's still only the equipment part. There's a lot of skill involved with filming and editing, and getting that skill takes time and patience.
