One thing first: The differences between Vegas Pro and Movie Studio are marginal for private users and most likely they do not fall out, which is why even how any cracking or other illegal procurement of Sony Vegas Pro not worthwhile in my eyes. Differences to expensive Pro version are on the one hand the support of professional video formats such as XDCAM, which only supports the Pro version, as well as the limited number of video and audio tracks (20 pieces each). But I doubt that this is not enough for the home user. The user interface is exactly the same as Vegas Pro and looks identical.
The program itself is quite complex and requires a lot of training, but I no longer really needed due to my work and the local use of Vegas Pro 8. If you know the key commands, such as "S" for cutting, the program is quite easy to use. Even the generation of transition effects by simply overlaying sliding video snippets is awesome. However, the Animating objects requires some practice until it goes perfectly. In addition to the layer masks work the animations as the Pro version. In addition, most of the effects of the Pro version here, for example, the Gaussian blur, I often need to Pixelize of people or license plates.
I decided not to Movie Studio Platinum 12, but the same for the Platinum 12 Suite. The decisive factors were above all the plugins as the 3D Titler and Magic Bullet Quick Looks individually cost normally $ 99. Even Sound Forge is included here, which I have not yet used. The higher price of around 12 euros is worth it in any case, especially for those who want to also deal with audio production. The Quicklooks of Magic Bullet is also great, they produce a few clicks cinematic film look.
In short: 45 Euro for Platinum Studio 12, 600 euros for Vegas Pro 12. The differences are tiny and not more than for production companies or TV stations relevant. Movie Studio is even more appropriate because of the included plug-ins for amateur filmmakers. Buy yourself the program, if you want to work professionally and possibly eventually want to upgrade to Pro, it is worthwhile in any case! The 45 euro are very well spent, I would buy the program again.
