I'm sure this has been covered before but I just can't find what I am looking for in the searches. Is there a standalone fisheye distortion program for the Mac?
Not sure if you want to eliminate "fisheye" or add it to your video. If you are looking for software to eliminate it, I use GoPro Studio, since I have a GoPro camera. Under "Import and Convert", is a tab for "Advanced Settings". In "Advanced Settings" is a Checkbox for "Remove Fisheye". I check it and process the video. It eliminates any fisheye affect in the video. Very handy for me, when I'm tilting my camera from the horizontal plane (which adds a fisheye affect to the video in the GoPro Hero 3+). I'm using GoPro Studio version 2.0.1 on an iMac running OS X version 10.9.5.
