I was a television director for 16 years, and a technical director for 10 years before that. In my experience, people are always chasing the ever changing technology. In my era, we went from 2 inch vtr, to 1 inch vtr, to Beta sp, to digi Beta, and then to Avid and the fully digital offerings. These days, domestically, I shoot MPEG 4 1920 X 1080 at 30fps, and I'm perfectly happy with it. The folks fixating on 4K now, will soon be chasing 8K......and then whatever comes after that.......and so the game goes on. My advice is to focus less on the technology and more on what you do creatively.
