When you buy a Mac it includes a free video editing program called iMovie. iMovie is the Gold standard of simplicity. I really can’t stress how maintaince free macs are. I know of churches using the same Mac for 10 plus years and it still runs like the day they took it out of the box. Best bet is iMovie on a Mac just for the ease of use.But If you are absolutely positively a windows user keep this question in mind. do you have a fast enough computer?
