Grip technique Consumer digital HD video cameras are ge ng smaller everyday. While using the 3D Mic Pro with such a small camera, it is easier to grip the whole system by the 3D Mic Pro’s hand grip. This technique will allow you to shoot more stable videos by balancing 3D Mic Pro and the camera like a camera stabilizer.
Page 19: Panning Technique
Panning technique While shoo ng video, it is absolutely necessary to keep the 3D Mic Pro aligned with the video camera. However, while recording only audio, you can physically move or rotate the mic to create a panning eﬀ ect for a sta onary sound source. For example, if you record...
