The first is nearly self-explanatory. Video is huge right now. It is dominating the world of marketing, and if you aren’t using video, you’ll almost certainly lose out to your competitors. That’s not a hyperbole; with video ranking higher on all social platforms and performing well in ads, customers are more likely to notice and respond to businesses using video.
Tripods range tremendously in price, and the quality of your tripod should depend on the level of camera and lens you have. If you're shooting with your phone, you can get by with a table mount like the Arkon Tripod Mount or a full-size tripod like the Acuvar 50” Aluminum Tripod. For a DSLR, Manfrotto makes a variety of trustworthy tripods starting with the Manfrotto BeFree and increasing in quality and price from there.
