How to Fix Fishbowl effect on a Zoom Q4n-4k Video Camera

Great tip from CaneMajor on Correcting Zoom Q2n Video Fisheye Distortion using Wondershare’s Filmora video editing software. Let’s see how I get on.

However, I had a second problem. The Video file wasn’t closed properly on the video, so I got another message:

The Finder can't complete the operation because some data in ZOOM003.MOV can't be read or written.  

Aparently, the MOV files filled the SSD, and the file wasn’t closed property.
Solution. Start a terminal console and run the following to clean up the SSD and fix the error. (Note, that instead of using /Volumnes/Untitled you can just drag the SSD from the desktop to the terminal console and it will get the correct name for the SSD. In my case it was:

dot_clean /Volumes/Untitled  

Problem sorted.
