What settings are you using for shutter speed? I don't feel like I'm seeing much difference from 1/30 to 1/80. I hardly do video, but I was recently trying to help a friend shoot some video of his tank. I had to bump the ISO to 1200-1600 at f/3.5 and 1/80 I hate that I had to use that high of an ISO!! Any advice for video setting shooting tanks would be great!!
The most common frame rates are 24, 25, 30, 50, and 60. Using 24 fps will give you a film look while using 50 or 60 fps will allow you to have great looking slow motion video by slowing it down in post production. For the same look you see on television shows or documentaries, use 25 or 30fps. Like any of your cameras settings, using and changing them is what will give you the best idea of what you like and what works best for you.
