DaVinci Resolve has a low learning-threshold for doing simpler things ( like making a gif ).
At the same time it has the power to do complex tasks – things like video editing, animation,
colour correction (grading), advanced graphics (VFX), automatic subtitling and text-effects,
as well as offering adequate tools for sound design, including Dolby Atmos and Auro 3D.
DaVinci Resolve is a must-have industry standard program for professional post-production artists.
And the best thing is that it offers a completely free version, fully upgradeable, with only a few
insignificant limitations vs the paid version – things that only professionals need.
DaVinci Resolve is used to create magic in most major Hollywood productions.
