Anyone know of a good reasonably (preferably free) application that will remove fish eye from videos?
Don't shoot at wide angle. If you don't want a fisheyed shoot use narrow or medium.
I've been trying to use the GoPro, but it doesn't seem to be working right.
I tried talking to there support, but they weren't very helpful when I said I was running it on a Mac.
I had issues using GoPro Studio too, the software does not like external drives or SD cards when you import or export files. Try copying your files to the desktop first then try to import them into the program. When done, export/save back to the desktop or anywhere on your local disk.
besides the gopro are you using any other video editing software like FCP X?
There are a bunch of plugins but unfortunately cost money.
