I have tried to use the DJI Go 4 app Version 4.3.3 with my IPad (newest IOS 12.1) to edit my Mavic Air videos.
I have uploaded the videos from the SD card in to the iPad and imported them into the Go 4 app.
When I try to edit the video and make clips from the original it works fine until I press save clips a new video.
I starts to process and gets to between 30 - 40% and stops. After about 30 seconds the app crashes and closes.
I have uninstalled, cleared the cache, even hoped on one leg as I spin lol nothing has worked.

It’s only happening on my iPad. The iPhone performs the edit without an issue. However the iPhone is editing the lower resolution video that was transmitted from the Mavic Air. The iPad is working with the full resolution videos from the SD card.

DJI Natalia,

I have tried another new iPad with 128 GB of memory and the latest iOS & DJI GO 4 release.
I get exactly the same outcome. I will detail the steps below in hopes that you can reproduce the issue and help solve this.

I import a 4 minute video off the Mavic Air SD card into the iPad Albums
I start the DJI GO 4 application and go into editor and the top Album tab
I click on the top left import icon and chose local videos
I find the Imported Mavic Air videos that had been imported from the SD card
I picked only one 4 minute video and click on the blue import tab at the bottom
I proceed to click on the imported video under my album tab and then click on the CLIP button at the bottom of the screen
I choose several clips from the 4 minute movie ( i have tried long clips and short clips)
I click on save on the top right and save as new footage.
I get a new screen that says creating your video. Please wait outputing videos and it goes thru 10%, 20%, 30% and then before 40% it stops and crashes.... I loose everything!

Please help, I am unable to create clips from my movies

DJI what’s going on “NO ANSWERS” NO SUGGESTIONS....NADA?

Issue is still happening right at 40% when trying to save clips as new footage

Hi Spartan DJI, sorry for the late response. As for the crash during the editing, may we know what's the resolution of the video you edited? If the issue remains after updating to the latest App, please kindly refer to the below and export the crash log for further analysis, thank you!
