Google's Wide angle Distortion Correction Technology. Google's new algorithm is developed from one of its previous researching projects. In its previous program, the operation processes this way: the user may send images in a low-resolution from one mobile phone to the server, then the server will send user back with a 'converting method' on those images, and users are allowed to convert those. If you're using Photoshop, you can do the same with the FilterLens Corrections function. Adobe Lightroom has a built-in lens correction tool.

The GoPro Hero line of cameras offer a high-quality way to capture footage that ordinary cameras can’t. Finepix viewer for mac os x. They go underwater, they’re light enough to attach to helmets, they shoot at high frame rates for great-looking slow motion. Still, the fixed lens means you’re stuck with what you’ve got—a small sensor with a fish-eye wide field of view. If that fish-eye look bothers you, how can you get rid of it?

A frame from the original clip, in which I went surfing, and managed to stand up.

Learn to love it

Easy, if impractical: getting used to the look is the easiest path of all. If your client doesn’t mind it but you do, set aside your personal preferences and roll with it. You’ll get the best resolution and sharpest results, plus you won’t crop away any of your image. But if your client has noticed…

The official option

If you’ve never imported your footage into FCP X, you may have luck with the free GoPro Studio app.

It works if you take the files straight from the card, but not if they’ve been re-wrapped.

However, when you import your footage into FCP X, the .mp4 that GoPro makes is re-wrapped into a .mov, and that apparently causes the fish-eye removal hidden in Advanced Settings to be unavailable in GoPro Studio. That’s a shame, though if you’ve dragged your footage into FCP X from the Finder (rather than using File > Import) you may not have problems.

Correct it with Photoshop

It seems like a less than obvious choice, but Photoshop can actually handle video as well as stills, and you can even apply its advanced lens corrections to video too. You’ll need the Exchange panel if you don’t have it already—here are some instructions. Install Exchange, restart Photoshop, then open the new panel from Window > Exchange.

Next, you’ll need a custom module to do the hard work. The latest one is called WideAngleVideo3, and you’ll need to search for that in the Exchange panel. Click the Free button to download it, then restart Photoshop to use it. (Note: if it doesn’t work after this step, restart your Mac too.)

Once you search, you’ll see this.

Drag your video clip onto the Photoshop icon, or use File > Open and locate it. Choose Windows > Extensions > WideAngleVideo3, then look in the panel that appears and find the settings you used to record this footage. I’ve used a GoPro 3 Black at 1080p in Wide mode, which is good for video quality but bad for fisheye. Luckily, just pushing the button works a treat. Scrub through the video, and even take a look at the Adaptive Wide Angle filter that’s been applied (to a Smart Object) if you want to see how it works.

And here’s the button I need to press.

To export, use File > Export > Video, choose a destination and format settings (H.264 on high quality should be OK) and wait for the export. It can take a while, though.

And here’s the button I need to press.

Correct it with FCP X

Another strategy is to correct the footage a little closer to the editing process. First, download the trial of Lock & Load from CoreMelt. (Disclosure: I create tutorial videos for CoreMelt, but you can use the plug-in used here for free, even after the Lock & Load trial expires.)

Lens Undistort lets you pick the degree of correction you want to apply.

In FCP X, add your clip to a matching timeline, then open the Effects tab. Look for C2 Lock & Load, then drag the Lens Undistort effect onto your clip. After a few seconds, it should deskew nicely, and you can adjust the Field of View parameter to match GoPro settings, or with Custom settings to match another camera instead.

This is much, much faster than the Photoshop method, but you have less control. Keep Photoshop ready for extra-tricky clips.

And here’s the corrected clip, which plays in real-time on my iMac.

Next time, shoot with different settings

You have a couple of options to minimise the issue a little. You can either shoot on a “medium” or “narrow” field of view instead of the default “wide”, or shoot at a higher resolution to make cropping less deleterious to image quality. You can’t combine these settings, though: for the 2.7K resolution, you only have the “wide” option.

In 1080p mode you have a few options, and wide will be most distorted.

While going through the settings menus on the camera itself can be an exercise in frustration, it’s quite easy to find the settings in the companion iPhone app, so do it there if possible.

Conclusion

While the plug-in used here isn’t the only way to de-skew GoPro footage, it’s the easiest way I know, and it’s free. There’s another free FCP X plug-in from Alex4D that seems to do a good job too. So get out there and do something silly with your camera!*

*No, not that silly.

As you know, the level of fisheye distortion is determined by the amount of tilt you have the camera set to. So setting to manual will allow you to make the right modification for the specific amount of tilt.

I don't know how to script I feel your pain! I know I've been led by the hand on my limited script experience when I dived into some sbs to anaglyph conversions awhile back. I wanted to let you know there is a download at the bottom of the page on the debarrel link - it contains the html file copy of the website and a dll file.

Spherical Panorama 3-Fisheye Stitcher, intended for creation of spherical panoramas. Universal support of standard and custom userls equipments (any type of rotators and tripods) Spherical Panorama 3-Fisheye Stitcher, intended for creation of spherical panoramas.Automatic and manual image correction.

I believe that is to aid you in the process. I'm not sure how that works either but just that there is more info available. Perhaps a kind soul on this website will be able to give you a briefing on scripting. Edit - out of curiosity I digged up this link: I should invest some time in it myself. I really only have a sub-sub-sub beginner understanding of avisynth and its true potential. This should be a good place to start for us uninitiated neophytes.

Edit - this program says it requires.net framework 1.1 to install. I just got a bunch of updates done for Vista Home Premium - the computer I'm currently typing at - I thought the newer.net was included in Vista? I have service pack 2 for home premium fy. I don't know how to script Perhaps a kind soul on this website will be able to give you a briefing on scripting. I installed, but I can't find it, hahaha. I don't know if you caught my edits in time before posting: There is a guide here for.

However I can't seem to install it because of a.net requirement. I'm gonna check to see what version of.net I have on my vista pc. I think there should be some other tutorials out there for avisynth. Unfortunaley there was another tutorial listed in the guides section but the link was dead. Code: LoadPlugin('PATH defish.dll') FFMpegSource2('PATH Fisheye.mp4') AssumeFPS #this is because ffms2 sometimes gets the framerate slightly off ConvertToRGB32 #req'd for defish, I'm using Rec.601 for this example, but you usually use Rec.709 for HD footage defish(fov=85) Original Defish(fov=85) Defish(fov=85, scale=0.7) When you 'undo' a barrel distortion or fisheye, you are left with 'gaps' - areas than were never recorded. Most plugins will automatically 'zoom in' to eliminate the black areas, but you're left with softer footage, and less field of view.

You can use defish with scale to control the amount of zooming (Get the pun??? 'Defish with scale' hahahha!!! ) This plugin doesn't have an center offset parameter - in your footage the center isn't actually in the center, so the distortion and correction are skewed (notice the objects on the left of the frame are more distorted than the right) Other FX programs can actually motion track background objects like the ground to (almost) automatically fill in the gaps, and there are other compositing 'trickery' that you can do (e.g. Poi file. The sky is easy to fill in for this particular) - so you try to get the 'best' of both worlds - less zoom in, and no black gaps Most people add sharpening afterwards (because the scaling and undistortion cause softness, especially on the periphery) - but the 'ideal' way to do it is through a gradient - so objects in the center are less sharpened, objects in the periphery are sharpened to a larger degree Of course you have to fiddle with the parameters and settings to get best results.

What are you using to edit? I use Aperture for Photos and PTLens is a great (I think free) plugin for Fisheye in Photos.

You can also use Adobe Camera Raw which is free, and works with Photoshop. Only problem is the Raw Files (DNG) import with wrong colors in Aperture in some cases. So using Adobe Camera Raw to do the import, then converting to JPG, then bringing them into Aperture for catalogueing and storage is another method.

For video I use Final Cut Pro X. CoreMelt has a great Free plugin as part of the Lock and Load set. Lock and Load is not free but the Go Pro Fisheye Plugin that comes with it is. And it does not only work on GoPros. It works well with the Phantom 2 Vision+ camera also, which is what I have. You do not have to pay for or register Lock and Load to get the Fisheye Plugin. It is truly free.

Point is, there are free options that work just fine for both Video and Photo! Final Cut Pro The CoreMelt plugins must be downloaded, then saved in the Final Cut Pro library / Plugins / folder. There is not install program and it is not done from within Final Cut. There are directions in the ReadMe file for proper placement of the plugin files. Note: when you drag the filter to your video in the timeline it defaults to a GoPro setting.

Do U Know Of A Fisheye Correction Program For Mac Free

If you are using the Vision+ you can then change the setting to manual, instead of GoPro, then tweak it to make it perfect. As you know, the level of fisheye distortion is determined by the amount of tilt you have the camera set to.

So setting to manual will allow you to make the right modification for the specific amount of tilt. Let me know if you have any other questions!
