Here is a suggested list of what you could use to get started. These links are either Amazon or to a post right here on my blog, and I use everything listed.
iRig mic is made for iPhone/iPad and plugs into headphone jack
This microphone is designed specifically for the iPhone and iPad. I’ve been very satisfied with the quality.
Order the windscreen that you’ll see with it. This helps to reduce wind interference when you say words beginning with “p”, for example.
Logo Mic Flag. In the photo above, you’ll notice the mic flag around my iRig. Don’t miss the opportunity to promote your brand while all eyes are on you. I created my own labels using Avery labels. I might at some point get this done professionally.
Bluetooth Headset. I use this headset so I can hear while the microphone is plugged into the headphone jack.
Microphone arm. You’ll need something to hold the mic. I’m currently using this space- saving mount so I no longer need a floor tripod.
Desktop Tripod for the iPhone or iPad. You’ll also need a tripod mount to hold the iPhone.
If you ever decide to use the iPad, you could do that too, but you’ll need a unit to slip the iPad into so it’ll attach to this mount. I have the iPad 4 and use this tripod mount.
Movo Lavalier Microphone. Depending on your video setup, you might also need a lavalier mic that will clip to your clothing. I purchased this one, but have only used it a couple of times during a speech.
Bluetooth wireless remote. This Bluetooth wireless remote will start and stop the video app without your having to tap your device. You’ll have to use Bluetooth as opposed to a selfie wire that plugs into the headphone jack (because the microphone will be there).
If you have a multimedia remote for doing PowerPoint presentations, check to see if it has multimedia capability. I have this Satechi remote, and can also use it to operate the camera/video function on my iPad and iPhone remotely.
Logitech Webcam. If you choose to use a Webcam instead of an iPhone, iPad, etc., you’re going to look better a high resolution Webcam as opposed to the one installed on your computer. I have this Webcam from Logitech.
Green Screen and Studio Lights. Are you considering taking things up a notch with Chroma Key (changing the video background with high resolution images or video), you’ll need more equipment: a green (or other color) screen and the right lighting. If the lighting is not right, the Chroma Key won’t work. There are tons of YouTube videos on how to Chroma Key, and I won’t get into that here, but here are links to my purchases.
Full lighting kit with screens. Lots of choices so shop around.
As with everything you do, having the right equipment will make the job easier. Look your best and you’ll do your best.
