I am trying to recover a video from the "Recovered Videos" local library but I get the following error: Error! Video could not save; Error domanin=PHPhotosErrorDomain Code=-1"(null)"; How do I recover these videos?

This error means you have a disk space issue on the device since a full copy has to be made. You can try to free up space on your device (https://support.apple.com/en-us/HT206504) or you can copy the file using iTunes (below) or some other method (see this FAQ for Windows)

See Apple's official documentation: https://support.apple.com/lv-lv/HT201301

Here are the steps for ScoreCam:

1. Open iTunes on your Mac or PC
2. Connect your iPhone, iPad, or iPod touch to your computer using the USB cable that came with your device
3. Click your device in iTunes. Get help if you can't find it
4. In the left sidebar, click File Sharing
5. Select the ScoreCam app from the list which is displayed. Video should show up in the "ScoreCam Documents" area
6. Select the movie and select the "Save..." button to save the file
