You'll get optimal footage if you have the right equipment, but sometimes you have to make do. If you're ever in a situation where you need to MacGyver a recording, just use your smartphone as the mic and laptop as your video camera. It makes sense if you think about it. Phones typically have the best mic since they were built for calls while a laptop has a more powerful processor, plus more ram and storage to handle recording video. No laptop? Another smartphone or tablet will work in a pinch, but other than Apple's, most tablets are horrendous at capturing photos and videos. The big takeaway point is to dedicate one device for recording the video and the other for recording sound. You can use Audacity, Logic Pro, and many other tools to piece it together and clean it up afterwards.
