This article covers 3 free video fisheye removal software for Windows. These software help you remove the fisheye effect from the video footage and hence produce a regular video with rectilinear frames.
What is Fisheye Effect?
Let me explain the fisheye effect with an example. Say, a video frame or a photo has vertical and horizontal straight lines. But when you try to cram more filed of view into that, it gets wrapped. The straight lines become convex curves and add distortion to the picture, also known as Lens Distortion.
In other words, the fisheye effect adds an optical distortion by wrapping the frame near the edges. In case of a video, this happens with all the frames throughout the video. The good thing about the fisheye effect is that it offers an immersive field of view as compared to a regular video and also captures a wider angle.
Why does it happen?
Generally, this effect happens with wide angle lenses where the field of view is larger than the size of the image sensor. There are also dedicated fisheye lenses which add the lens distortion (fisheye effect) to the footage in order to capture a wider field of view. Action cameras and drones are two of the main gadgets which use the fisheye effect to take wide angle shots.
While the fisheye manages to capture a wide field of view, it can also be annoying in many cases. Thankfully, it can be corrected with software even after the footage is captured. Since the distortion varies with the lens and camera, there is no universal solution to fix the fisheye. But, you can create presets for specific lenses and cameras or otherwise try various geometrical configurations to find the most suitable configurations for fisheye correction.
If you have a video with fisheye, you can use any of the below-mentioned software to correct the lens distortion and make the video look regular. All these software provide you with several controls to adjust the axes, geometry, and perspective of the video. You can tweak those controls to make the curve areas rectilinear. So, let’s check out these software one by one.
