What sort of gear do you use to capture video of your display? I was planning on just using the video mode on my Nikon D3100 DSLR, but I just read the manual and found that it will only record for 10 minutes at a time. I'm assuming that the sound quality will be pretty bad too. I have one of those el cheapo 'Full HD' video cameras, but the quality is pretty shocking. I'd like to try to get some quality footage of my light display this year, but I don't want to spend a fortune on a video camera which will almost never get used. Any suggestions?
