I'm very disappointed with the loading and rendering times of Vegas Movie Studio 15. When the video file that I'm trying to edit finally does load in the program, its a pixillated mess. I have noticed that many users are experiencing similar problems. I just downloaded and installed the latest program update (Build 106) but the problems persist. It appears that MAGIX has released a new version of the software without thoroughly testing or debugging it. I'm a musician in a jazz band and I use Movie Studio to edit and post concert videos. Unfortunately, Vegas Movie Studio 15 is unusable in its current form for this purpose. I will be uninstalling it, and trying to go back to an earlier version of the program, which worked fine.
