I used Movie Studio Suite since 2012 and in 2018 made the foolish mistake of upgrading to Vegas Pro 16. A monumental error a) because of the ludicrous upgrade price of £240!!! (on top of all the other upgrade fees I had shelled out) and b) because it is the most buggy software I have used in 20 years.
I have repeatedly asked for my money back for over a year now and keep getting pushed back to support, who are less use than a chocolate frying pan.
DO NOT BUY THIS SOFTWARE! Really unless you WA t a life of pain, do not buy it! My last project was 3 months late because of all the crashes (one time I couldn't even load the software for 3 weeks and support hadn't a clue, I fixed it myself in the end. On other occasions (note the 's') it repeatedly crashed because of software Magix supplied with installation! Then if course there was the reliable 2 hour or less crashes every session).
I have since moved to Davinci Resolve - wow, a breath of fresh air. A slightly steeper learning curve but you feel you are using top of the range software, not some kids programme, and the results are infinitely more professional.
PS the free version of Resolve is as functional as Vegas Pro.
