The phone says 50 MB but if I want a consistent data rate I have to set UL/Low to 45. It seems there is some sensitivity in rendering (if not at or below data rate it fails in some manner) but if you match or are low it does a fantastic job. Working with 4K (over 30 gigabytes ) I have to say I love this program. Yes you have to tweet your hard ware a bit to have a fantastic experience, but when you do you realize just how good the Vegas work flow is. Yes I am a fan boy and used either Studio or PRO for over 14 years from a old Canon Vixia 1080i to the really good consumer 100 mb Gx8, but today I really had the best editing experience I've ever had. Fast and great output. I'm considering getting a BM 4K pocket but I'm not sure I'd see the "added value" of the full Resolve suite, Guess you could use the special effects segment.
