I don't know how but I have a some videos in the DJI editor but I've never used it. One I want to get out of the editor has a flight where I think it was 6 bird hits. I don't have the video anywhere else. My card has been erased since then.
If the dji app is on an IPhone, save the film clip you want, it will then be stored in your 'me upload history' folder on the app, connect it to your computer wait for the prompt and copy it over to your video library. Not sure about android phones but assume it would be the same.
