A fisheye lens is a lens that is embedded in video or film cameras, with an extremely wide angle of view (more than 180 degrees). This lens falls within the angular lenses and has the particularity of deforming the image with convex curves. They also have a large depth of field (distance between the first and last point in focus of the frame). But if you have a video that was recorded with a fisheye lens and you need to remove the aberrations from the frame, we are going to present you three programs to remove the fisheye effect in videos.
With these programs, you can convert videos taken with fisheye lenses to a normal lens. It does this with preset tools, but you can also use "geometric settings" to correct the frame.

Easy Video Fisheye Fixer is a free program that removes fisheye from videos. Undoubtedly, the platform is one of the simplest on the list for correcting lens aberration. The interface has four controls that let you correct X-Y coordinates, make fine adjustments, undo changes, and play the video from its interface to see the effect removal in real time.
HitFilm Express
HitFilm Express is one of the most used free programs for editing video. Among its functions, the platform has the option "Remove the fisheye effect". To do this, you have to go to the bottom of its interface and select "Media". At this point, drag the video to the section and drop it on the work area (timeline). Then, go back to the bottom left menu, click on "Effects" and select "Wrap". Inside this folder you will find the effect "Cam Lens Distortion", from where you can correct the distortion from its controls:
- Presets
- FOV (Field of View)
- Reverse
- Center
- Scale Anchor
- Layer Resize
- Wrap (Tile, Reflect, Blur Reflect, Off)
You can view the changes from its previews (one shows the original video and the other the modified one).
VideoProc
VideoProc is another very good video editor that, in its free version, only allows you to process five minutes of video. But the good thing about the platform is its built-in tool to correct the perspective of the video and eliminate the aberration of the frame. Once you load the video into its interface, you have to click on "Toolbox", which is at the bottom, and select the tool "Fisheye tool". A popup window will open with several controls to remove the distortion caused by the fisheye.
With the programs you can remove the distortion produced by the fisheye lens in videos.
If you want to test, we leave you a sequence from the movie "Fear and Loathing in Las Vegas", made extensively with fisheye lenses.
