This is the most stable and feature-rich video editing software available out there! I’m on Windows 7 and I love it, because unlike others VSDC barely crashes.
Seriously, after basic linear programs like MM, this is a huge step towards professional post-production. VSDC has everything from zooming and cropping to blending modes an color grading. It’s quite intuitive and allows for keeping the highest quality on the output and has no “surprises” like watermarks or other unexpected things you find at the end of the project. I strongly recommend it to anyone interested in video editing on a serious level. You’ll never regret.
