Hi,
I am looking for a PP video editor for beginner (Mac user) ... Is there any good recommendation ?
Many thanks in advance
regards Adrian

Start with iMovie. It's free and included in the Mac OS. It has most of the necessary functions for a beginner. Later switch to Final Cut Pro which has more functions. They use the same editing principal. Therefore it's easy to change between these two programs.
Another good option is DaVinci Resolve, but the learning curve is much steeper compared to iMovie and FCP.
