Include a full transcript of your video in the blog post. If you're a words guy like yours truly, you'll want to read along and reference the material after you watch the video. It's a nice way to flesh out your blog post while using the content you've already created. Provide a link to your video to a service like Rev and get your full transcript without typing a thing.
You can work with an agency to develop the videos. This option is more expensive, and you will often end up spending thousands of dollars for a single video. However, you get what you pay for. If you’re looking to create a single, impactful video (or if you have a healthy marketing budget), working with professionals is certainly a beneficial option.
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.
Professional cameras, like DSLRs, give you fine control over the manual settings of shooting video and allow you to achieve the shallow depth of field (background out of focus) that people rave about. While they're primarily used for photography, DSLRs are incredibly small, work great in low light situations, and pair with a wide range of lenses — making them perfect for video. However, DSLRs do require some training (and additional purchases) of lenses.
