I have been trying to use the video editor with my Phantom 3 standard to upload movies made off the DJI app to facebook.  Everything works until the end when the result on facebook is a blank box with no picture where you would click to start the made movie.  If you click the blank box the movie will start.  It seem that the older app would a least put a picture in the box.  Does any one know what is going On?

Never used it so sorry I can't give you any advise, other than try Movie Maker or other editing software that actually works out the box.

It seems to work well and easy to use except for glitch at the end of the upload with  an empty box instead of a picture of the start of the flight.  I have used movie maker before and it works well.

I agree.  I use Movie Maker, it's free, comes with windows and is pretty easy to use.
