The Autel Evo drone series is known for capturing stunning aerial footage. However, the wide-angle lens used on these drones can sometimes create a fisheye effect, distorting the image and making straight lines appear curved. Fortunately, there are several ways to remove or minimize this fisheye effect from your Autel Evo videos.
Understanding the Fisheye Effect
The fisheye effect is a type of distortion caused by wide-angle lenses. It’s characterized by a bulging or rounded appearance in the center of the image, with objects at the edges appearing stretched or warped. While this effect can be creatively appealing in certain situations, it’s often undesirable for professional or realistic-looking footage.
Methods for Removing Fisheye from Autel Evo Videos
Here are some effective methods for removing the fisheye effect from your Autel Evo videos:
1. In-Camera Correction (Lens Correction)
- Autel Evo App: Some Autel Evo drones offer a lens correction feature directly within the Autel Explorer app. This feature can automatically correct for lens distortion, including the fisheye effect, during recording. Check your drone’s manual or the app settings to see if this option is available. Enabling this setting is the easiest way to mitigate fisheye.
2. Post-Production Software (Desktop)
- Adobe Premiere Pro/After Effects: Professional video editing software like Adobe Premiere Pro and After Effects offer powerful lens distortion correction tools. You can use these tools to manually adjust the distortion parameters and remove the fisheye effect. Often, these programs have built-in lens profiles for specific cameras, including potentially the Autel Evo. Look for “Lens Distortion” or “Optics Compensation” effects.
- Other Video Editing Software: Many other video editing software packages, both free and paid, provide lens correction capabilities. Explore options like DaVinci Resolve (free version available), Final Cut Pro (Mac), or Filmora to find a solution that fits your needs and budget.

3. Third-Party Plugins and Applications
- Dedicated Defishing Plugins: Several plugins specifically designed for removing fisheye distortion are available for various video editing software. These plugins often provide more advanced correction algorithms and features compared to built-in tools.
- Mobile Apps: Mobile apps dedicated to video editing are also becoming increasingly powerful, offering tools to remove fisheye from footage on the go. Research popular apps to see their available features.
Tips for Minimizing Fisheye During Filming
While post-production correction is effective, you can also minimize the fisheye effect during filming by following these tips:
- Avoid Extreme Wide Shots: If possible, try to avoid shooting at the widest field of view. Zooming in slightly can reduce the prominence of the fisheye effect.
- Compose Shots Carefully: Be mindful of how the fisheye effect will impact the composition of your shots. Place important subjects closer to the center of the frame to minimize distortion.
- Use a Gimbal: A stable gimbal can help to keep the horizon level and minimize the appearance of distortion, particularly when making panning movements.
Conclusion
Removing the fisheye effect from Autel Evo videos is achievable through various methods, allowing you to create more polished and professional-looking footage. Whether you choose in-camera correction, post-production software, or third-party tools, understanding the techniques and applying them effectively will significantly enhance the visual quality of your aerial videos.
