DefectiveDave Posted December 3, 2013 Share Posted December 3, 2013 Recently I've been doing some research to replace the camera I've been using to film and analyze myself skiing this past year (mostly slalom). The quality just doesn't cut it an I need something better. Currently my research has been focused on the gopro hero3+. I'm attracted by the ability of the camera to do 720p at 120fps, which will allow me to slow down the action during post processing. However, the camera has the significant drawback that it has an extremely wide field of view, which makes it more difficult to capture detail at a distance (say behind a ski boat). So in addition to purchasing the camera I will have to modify it to accept a new lens. I'm currently considering modifying it to accept c-mount lenses which will provide me with a variety of options to zoom in closer on the action. There is a kit which was recently developed which should provide this capability (http://www.back-bone.ca/). However, I'm also concerned about the image quality on the hero3+ at 120fps. The current camera I've been using has an 8mbps data rate at 720p with 30fps (h.264 codec), and the image quality leaves something to be desired due to compression artifacts. I know the gopro is capable of 45mbps (also h.264 codec), but normalized to 30fps that is only 11.25mbps. So I'm not convinced that this is the way to go. However, the only alternative I've been able to come up with is using an industrial camera that would output raw sensor data, sans compression, to a laptop. Strangely, given that I've already got the laptop this would be a wash on cost, but it would be a pain to haul a laptop out to the lake and back, not to mention waterproofing concerns. Can anyone here provide advice on building a camera system to film our skiing adventures? What types of camera and mount setups do you all use? What are some good camera options? Is slow-motion even beneficial? While I like the idea of being able to do slow-motion on the gopro, I'm not entirely convinced of the utility of doing so. So a reduced frame rate is definitely acceptable to me if I can get better image quality. Any input is greatly appreciated! Link to comment Share on other sites More sharing options...
