I am going to keep the camera on 60fps until the helmet mount arrives, and then I will experiment further.
Have any of you noticed similar vibration problems at 30fps?
Various ways of storing video have various methods. But as a general rule.. very few systems store a full shot every frame. What happens is that a full shot (key frame is stored.. then for the next few frames.. changes from that are what is stored.. then another keyframe.. sometimes a partial key frame is stored and so on. Much smaller file size. These mechanisms are well documented and easy to look up, just telling you for general information
You can see how vibration might be a problem. Really good camera's deal to some extent with shake by taking a shot with more pixels than they use. THe camera figures out with an algorithm where in its field the shot should come from in order to be the least number of changes from the previous frame and generates the frame from that bit of the field of view. Which .. if the vibration is within the range of the camera's field is just brilliant.
SImplified as hell.. but.. maybe useful.
