Back around 2003 when I first started using Premiere, I had problems because we used a Matrox hardware/software product with it. I had a new computer built for my employer a year ago and have used mostly Premiere and Photoshop. I can't recall any problems at all. The Creative Cloud interface seemed very convoluted but once everything was up and running the programs worked great for us. A lot of what I do is shot on green screen and Ultra is great. With lighting adjustments I have been getting amazing keys where you really can't tell it's green screen. Not saying you are having problems because you're doing something wrong, but after working years in corporate video production, I finally arrived at having a relatively a stable workflow. Beginning around 2003 we mostly did video for live projected presentations. Wasn't even 720. Amazing how things have progressed. My Galaxy S5 shoots better video than our $7,000 camera back then. I would be interested in hearing from some of you guys having problems. Are you shooting TV commercials in 4K?
