High-End Lightworks Video Editor Finally Says Why They Didn't Go Open-Source Yet
Way back in 2010 it was announced that Lightworks would be going open-source as this high-end, non-linear and cross-platform video editor solution. This video editing system has been used by many films over the years from The Wolf of Wall Street to Bruce Almighty to Moulin Rouge to Pulp Fiction as well as many other movies and television shows while also being approachable enough that it's used by less advanced video editing enthusiasts. Lightworks going open-source would be a big win, but ten years after their failed plans were announced they finally have shed some light on why such move away from being a proprietary application never materialized.

Important Patches Land To Improve GNOME's Multi-Monitor Experience With High Refresh Rates
