The sound was the ONLY thing I had covered! If you know how to record anything then you can record it no problem. I just took a microphone (I’ve got a Blue Baby Bottle, but I’m sure any vocal mic would work…People use SM7Bs and RE-20s for this stuff frequently if you’ve got one or you’ve got the cash), put it on my desk (you could put it on a stand and aim it at your face, but this whole thing is so cumbersome I wanted to avoid that), and pointed it at my mouth. I made this a mono input in my DAW–Studio One 4. I then took the stereo out of the MnM into my interface and made this a stereo input in my DAW–that’s it. My monitors were muted and I was using (open back, though really closed back is preferred but it didn’t matter) headphones. I pressed record on the camera, then pressed record on the DAW. I said “1, 2, 3, 4!” and then hit play on the MnM, so I could later clearly see where to sync my audio. Then I just cut the countdown from the project entirely. The audio on the camera itself I decided not to use at all.
For video I got a cheapo Amazon-brand Tripod, put it up high, angled it straight down and straddled that bad boy between my legs like the precarious little slut I am. This is why a few minutes into the first part of the video I just barely bump it and the whole thing is angled poorly for a bit 
Syncing isn’t that bad as long as you don’t have variable frame rate which I’ve discovered is a BITCH to deal with. Phones record in variable frame rate instead of fixed frame rate (apparently there are apps to work around this?)…This means for whatever reason your audio is going to jump/skip around if you import the file into video editing software. I had my recorded audio matched up perfectly with the video audio and halfway into the video it was completely out of sync. I had to take this crappy video recording, use a crappy converting software that took an hour to convert 13 minutes worth of video, then import it back in to my crappy video editing software and try again. The syncing got a little off as I mentioned–requiring me to shift some things around throughout the video–but it was much more workable than before.
EDIT: Oh I also recommend having a script in front of you or at least an outline. I thought I’d know what to talk about but when I pressed record my mind went blank and I froze. So real quick I pulled up notepad and stream-of-conscious wrote everything I wanted to talk about. This made it WAY easier and I didn’t have as many pauses or moments where I ask myself what to talk about next.
But I made this Let’s Dance patch when I was trying to deeply learn the ins and outs of the MnM so I sat down with it by itself, my MD far away. Now the two are right in front of me, never disconnected from each other.
