In my experience, earlier OpenShot versions were somewhat unreliable, but most of the functionality was there. Effects worked as expected for the most part, and while the interface was a bit awkward to work with at times, most of what the application was offering was there to be used. Having said so, my main problem with OpenShot was performance. Even when working with videos well below HD quality, the application would choke on them. Simply trying to add a single audio track to a single video track was a nightmare, for the preview render would be useless, thus leaving me editing blind.
BIG STEP FORWARD
Fortunately, come OpenShot 1.3.0, things have IMPROVED. Yes, that's an improvement worth the uppercase. To begin with, there is a host of new features which make OpenShot an even stronger and more powerful editor (the latest Blender 2.5.6-powered 3D effects are truly something, specially fun is the world maps feature!). Granted, great features were already there in previous releases, but what good are they if the basics are not tight? The good news is that things are way tighter in this release, including a major performance improvement. In fact, I was able to do some video editing on old laptops with poor on-chip video cards... Impressive!
Here's an OpenShot 1.3.0 video introduction from Jonathan Thomas himself:
I recommend checking out the OpenShot 1.3.0 Vimeo PAGE for some more interesting videos, demos and information.
If you have never tried OpenShot or if earlier versions disappointed you, I definitely recommend giving 1.3.0 a try. It's still not what I would call a professional video editor, but it is a huge step in the right direction.
