The idea is to set up a second camera without having a second Camera Operator. This ‘B’ camera angle offers dynamic movements so that you can cut away to the footage when needed.
Unmanned, unattended, looping, automated, it all sounds pretty good. Yet you can see how this basic system fails to provide many of the ‘Smart’ features of the more expensive products coming to market. On the flip-side, one advantage is that with this basic circuit one can expand this idea outside of just a typical slider.
