DaVinci Resolve 12.5 How to use it to edit and flip upside down videos 

Hi, thank-you SO much, I have watched a dozen Da Vinci youtube videos on how to edit and NONE of them showed me (me, total newbie ignoramus) how to actually USE the razor. You are THE FIRST and that makes you THE BEST! Thanks, mate - Jim from Canberra

Even easier way is to be in EDIT mode, select the clip or a pic, click on: Inspector, Transform, Flip = DONE!!!
