We can't talk about video SEO without mentioning YouTube. After all, it's the second largest search engine in the world after Google, and somewhere your video content should definitely be ranking. Consistent videos on YouTube answering your target audience's questions can continue to rank and build up awareness for months and years to come. And because YouTube is owned by Google, a high ranking on YouTube also frequently correlates to a high ranking on Google.
White balance tells your camera the color temperature of the environment you're shooting in. Different types of light have different colors. For example, incandescent bulbs (like what many people put in a lamp) have a very warm color. The fluorescent lights (if you're reading this in an office, look up) are a little bit cooler. Daylight is cooler yet. Before you begin shooting, you have to adjust your camera's white balance according to your setup.
What you need are deep insights into your audience. To find them you'll need to run surveys, conduct interviews and sift through data. Start by gathering basic information like demographics, then move onto more detailed considerations of personality and preferences. Be sure to get to the root of what your audience need, what they want, and which problems you can help them with.
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.
