The Limits of Defishing Fisheye Videos You Need to Know
For GoPro users, it is pretty easy to capture video with fisheye lens distortion being removed directly, if the linear FOV mode is enabled, which offers software-level correction to GoPro fisheye distortion. However, you have to understand this mode only works with 2.7k and full HD 1080p video with frame rates at 60fps or below. If you want to render your 4K 2160p video footages with a fisheye and give a rectilinear result without bends or curves, you will need to do some post production.
Shutterbugs are not strange with the professional video editors like Adobe Premier, which are available to fix fisheye effect, stabilize shaky video and more professionally. But they may be backed down either for the complicated user interface or the unsatisfactory performances such as lagging or freezing in editing and processing huge 4K UHD videos.
