Overview
Convert fisheye video to rectilinear, and vice versa. It is based on the angular mapping functions actually used in fisheye lens design, to get the best possible results. It can also be used to correct the slight distortion of some wide-angle converters, or to bend the image beyond recognition for special effects and light shows.

- Non-Linear Scale: The image will be stretched/squished to fix camera scaling between 4:3 and 16:9. Like used in GoPro’s superview.
- Use negative values for up-scaled videos
- Use positive values for down-scaled videos

Tips
- this filter is very CPU intensive on high resolution videos so using Settings > Preview Scaling will have a massive impact allowing realtime playback even for 4K sources.
- See also Lens Correction Video Filter which supports keyframes unlike this filter.
