Anyone looking for a professional grade NLE (non linear video editor) on a budget (read: FREE!) should really try the newest beta for DaVinci Resolve 11. Quite amazing, actually, and I still cannot believe this is freely downloadable.
The latest Lite version can work with and output up to 4K UHD (3840x2160) resolution! Except for Stereoscopic editing, noise reduction, and motion blur, everything is functional.
It’s been running stable for me. Bye bye Premiere CS6 and Lightworks! I was getting fed up by the licensing restrictions of Lightworks, and this is the perfect NLE replacement.
