I’m using both PowerDirector 12 Ultra and Sony Vegas Studio Platinum 12 respectively on one of my projects. Comparing the two programs, I find PD is way simpler to learn and operate. What’ more, it includes more features that can be applied in my daily use, for example, menu, title, transitions, etc. It can make DVDs/video files in a quicker way than Sony.Up until now, PD is always running well with no crash or lockup, but sometimes the computer’s slow speed may cause a delay. I used to try Adobe Premier Elements and Pinnacle Studio, the former one is good, but the later one makes me feel very bad. I use PowerDirector to deal with videos of my grandkids when they play balls. Though it is running well, I won’t give a 5 star score but only 4, because it does not provide music files. If I want them, I have to buy from Smartsound additionally.
