DJI had high ambitions to add such software to the basic App, but I believe DJI will come through with fixes and improvements to make the Director work to help many people post quick and easy videos.
The current Director software is broken in my opinion and I have found no one who was successful in using to completion. Some features seem to work, and you can select clips, but then in my experience the App stops progressing to the next step of assembling the video and adding the music. So I gave up, and am watching for an IOS App update.
It may take them months to get it right, but given what DJI has accomplished with the P3P and P3A, I give them good odds, the App will get better and better over the next year.
