After using MSC equipment for approx. eight mos.,I purchased my video rig in Aug. of 2009. My reasons were two fold: A larger fee and more opportunities. At that time, the industry logic was that audio/video was the future, but it was not to be. Both the number of shops and the fees began decreasing. In addition, the rejection rate was considerably higher than for traditional shops. My last audio/video job, of approx. 160, was 2 1/2 yrs. ago, so my investment of $400 was quite rewarding.
In my opinion, and in today's shopping climate, one would reap a greater advantage from the heat burning the money would produce than investing in audio/video equipment. That, though, does not include IF one has a SmartPhone, which an MSC will accept, that could be employed to complete the work.
In the past, no video work I recall seeing would accept glasses. The claim was that movement of the head produced unacceptable images.
