The iPhone is a really good recording device now, especially if you want to go down the 4K route as the 6 Plus has this now. Also, you can get some cheap tripod mounts for them.
I tend to make video reviews of devices, products I have and put them on You Tube. Most of the time I use my Panasonic FZ200 bridge camera as with it having an optical zoom (the iPhone only has a digital zoom) I find its better for framing the scenes in my video. But saying that, if you are using a 6 Plus for recording and use 4K, you can sacrifice a bit of digital zoom as you have more pixels to play with in 4K.
When doing the video reviews, I use a lavalier mic that connects into a digital recorder. I use this as the sound from pretty much all built in camera mics is a bit ropey and I get really high quality sound with the lavalier, digital recorder. I later use Adobe Audition to enhance the sound slightly, if its needed. You can also use a free application called Audacity. I later use Adobe Premiere Pro to do any video editing, adding titles and also to sync the audio track from my audio recorder to the action in the video. I’ve tried Final Cut Pro for my video editing, but find my workflow is better with Premiere Pro.
When I make the video guides for stuff on the iPhone, iPad, Mac. I use the Quicktime player (which comes included with Mac’s) to record the screen of the iPhone, iPad, Mac. I also use the lavalier mic and audio recorder to record the sound. When I have finished recording, I use an application called ScreenFlow, which allows me to zoom in on parts of the video, so as I can show things in more detail for example. After this, I load the finished video into Premiere Pro and do any editing and adding of titles. After this its ready to upload to YouTube.
It does sound complicated syncing two audio tracks. But with modern video editors it’s a fast and simply process. The only thing you need to remember (as it makes for a perfectly synced track) when you start recording is to clap three times in front of the mics. This performs one of the same functions as the clapper board you see in the film industry and this is it makes a loud sound spike in the audio’s waveform, which is easy to identify/your software to identify when syncing the tracks later in post production.
I learned a lot about audio enhancing etc from someone off of You Tube. He has some really good video’s. Here’s a link to his channel.
