We live in a visual world. Video makes a big impression. You can make nice recordings with your smartphone or a basic camcorder but are they good enough for business today? Let's look at how you can create your own quality videos in full high definition (1080p).
For the best results, get the right equipment and learn how to use it. I did lots of research and also talked to video expert Nikola Danaylov of the terrific Singularity Weblog.
The GH3 is easy enough for a beginner and capable enough for a professional. Since the GH4 with 4K resolution is now available, the GH3 is an even better bargain. You might be able to find a used one. Use the savings on other equipment.
The lens is very important. You may change cameras but can keep using the same lens (unless you change systems).
The lens aperture is f1.4, which allows lots of light gets in. That lets you get great results in situations with lower lighting. You also get a shallow depth of field: the background is out of focus, which puts attention on the foreground. You'll see this used in movies and commercial photography.
You'll need a tripod designed for video. When you're working in a controlled environment like an office, you needn't spend extra for a lightweight tripod or even the latest model. I picked up a discontinued tripod from a camera clearance outlet.
As you gain experience, you may want to get an external microphone. A shotgun mic is a good choice (e.g., the Rode VideoMic Pro). Another option is a wireless clip-on lavalier mic (e.g., the Sennheiser EW 112P G3). To get more sophisticated, get a second camera and more lens!
Editing is easier if you have good video, good audio and few mistakes. There are many editing tools. I've used Adobe Premiere Elements but don't find it intuitive enough. I switched to Cyberlink PowerDirector. You'll find good choices at TopTenReviews. Using the trial version will help you decide.
YouTube is an ideal place (e.g., my channel). Your video editor may even do the upload automatically.
Here's a short video recorded in my office in a single take. The frame rate is a cinematic 24 frames per second and the light is from a window. The script took several days to finalize and memorize. This is not the first take.
PS The GH3 also takes great photos.
