Welcome to our first tutorial! This tutorial is broken into two posts (and two videos).
These tutorials will show you how to correct the fisheye look that you get from the wide-angle lenses included on the GoPro HERO HD cameras. This will work for corrections from other cameras, too, and you can correct a lot of issues besides the fisheye look, including chromatic aberration, fringe and vignette, plus you will also have the ability to transform the perspective. I am not going to show you most of this, since our main focus here is on correcting the fisheye look.
The first tutorial (this one) will focus on correcting the video through After Effects. The second will fix the problem in Photoshop (yes, you can work with video in Photoshop – but more on that in the next post).
So, here we go. First, check out the video tutorial below. Then, if you prefer a written version of the instructions, scroll on down!
Instructions for correcting the fisheye look in After Effects:
- Import you footage into After Effects.
- If working directly in After Effects, choose File –> Import, or double click in the project panel.
- If working in Premiere Pro, select the clip that you want to correct, right click and select “replace with after effects composition.”
- This step is not necessary if you sent your flip from Premiere Pro into After Effects.
- If you did start directly in After Effects, simply drag the clip in your project panel to the Create a new Composition button.
- At this point, I find it helpful to turn on the proportional grid. This will help you in a few minutes to guide your plane to be a true straight line.
- Find this under the Effect menu and in the Distort category.
- Since this is a 32 bit effect, you should
- First, you’ll want to check the reverse lens distortion option. If this is unchecked, you will actually be distorting your image more.
- Next, adjust the field of view parameter until the plane you have chosen becomes a straight line. Mine is set at about 80.6.
- This step is optional. When you adjust the field of view, you may notice that the video is slightly enlarged. In order to compensate, I have scaled down the video a little.
- If you have done the above step, you’re video will no longer be the size of the frame and will be surrounded by black. To compensate, try turning on the resize option. I have set mine to max 2X. Then, simply readjust the size of your video to fill the entire frame.
- I have decided not to change the Field of View Orientation or the View Center, but feel free to adjust these and experiment all you like!
- Select the Composition menu and select Add to Render Queue.
- In the Render Queue, click on the yellow Output Module and select a format for rendering.
- Click on the yellow Output To and choose a location to save your rendered file.
- Click the Render button.
- Wait for you composition to render. That’s it!
