I was trying to ask support a question about the app on the iPhone to export a video that was captured with the app on the iPhone. They did not know anything. I then did my own researching on the app and found out how to export the video fro the Amcrest Pro app to your photos/video on the phone.
1. In the App go to My Saved Files
2. Click on the box in the upper right corner of the screen (box with pencil in it)
3. Then select the capture from the Amcrest pro app you want to send to your photo/videos.
4. Finally click on the middle icon at the bottom of the app and the file will be sent to your photo/videos on iPhone.
