Having been working in the video business since 1988 I have amassed a great amount of knowledge of both the kit and production values over the last 30 years.

One thought on “AJA Ki Pro Quad 4K & 2K Recording

  1. Seems a bit useless if it’s not actually recording the raw files only passing them through. Doesn’t that throw away most of the benifit of shooting in raw??
