I just started using Shotcut yesterday and thanks to its well thought out, intuitive UI, I'm already being productive with it.* Like others, I tried some other options running under Linux but I wasn't impressed. I guess I'm spoiled from the days of using Sony Movie Studio (the lite version of Vegas). As I do about every year or so, I thought I'd re-investigate Linux options and this go-around I started trying to use Flowblade. It seemed ok (although awkward) until a clip on the timeline suddenly disappeared for the second or third time. That was it -- I was out of there! I had intended to try out Shotcut first but I couldn't because, for some reason (likely related to the Intel graphics), it wouldn't run on my HTPC. So after giving up on Flowblade I decided to try running Shotcut on my old laptop from a Live DVD (which is how I always test software before committing myself to it). Lo and behold, I booted into the live DVD, configured a few things, connected to the Shotcut PPA, installed Shotcut and ran it... Everything seems to be working great. So, yeah, many thanks to the Shotcut team!
The system I'm running on is a 2-core Sony VAIO VGN-SR540G with 4G memory running Linux Mint 18 (MATE edition) from a live DVD.
- That is, if one considers the making of a prank video being productive.
