GoPro Hero 6 Lens Correction

[tegumedia]

Hello,

I would like to ask can you suggest me any filters or values for GoPro Hero 6 to remove the fisheye effect?
Under Lens Correction I could find presets only for older GoPr3/4.

Thanks,
Tegu

Go Pro's own Studio software can help quite a bit. And New Blue Video Essentials IV, which comes with VS, also has a good filter for correcting fisheye.

Thank you but the Fisheye effect especially adds fisheye effect to the image and not removing it. Also I am looking for GoPro 6 defined values and not general.
The GoPro software is not supported anymore (or something like this..), once I tried it but it was completely buggy and couldn't solve anything with it.

Examples:
The original output from the camera:

The available presets for lens correction:

My used values for lens correction & the result:

It's quite a big improvement but I am looking for GoPro 6 specific values.

So my question is can you suggest me GoPro 6 specific lens correction values or some any workaround to remove the fisheye effect?

Tegu, based on Ken's suggestion, try the following:

1. Before ANY Editing, Cutting, Added Text, etc, first select (click) the entire GoPro Hero 6 clip you brought INTO the timeline FIRST to do the Lens Correction.

2. Under the "FX" heading to the right of the video editing viewer, click the "FX", then look through "ALL" the options OR choose NewBlue Essentials II as Ken Berry as the LENS CORRECTION is in there. Choose "Lens Correction." They should be alphabetical.

3. As you left-click on the LENS CORRECTION, it'll pop into the video editor covering the video on the left. Once it does, DRAG the same ICON of the "Lens Correction" down ONTO your GoPro Hero 6 video ONTO your video timeline --- BOOM!! Instant HORRIBLE DISTORTION! It's OK, we can fixed it in a moment...at least, to my satisfaction.

4. Under EFFECTS (I have mine on the far upper-right), choose "Customize Filter" for the highlighted Lens Correction and the NewBlue Lens Correction display will become visible in the center of your screen.

5. IMPORTANT: UNCLICK KEYFRAMES!!! The other two ("Show in Preview Window" and "Show Actual Sources") can remain clicked if your computer isn't a slouch. Again, UNclick Keyframes.

6. For an initial "Trial" for your Lens Correction, change the "Distortion" value of 50.0 to either a NEGATIVE 12 or NEGATIVE 14 (-12 or -14), depending on your liking; Set "Zoom" to six (6). I keep the X and Y Axis at 0...that's just me.

7. Play around with that to see if that simple thing doesn't at least help a bit...Hopefully it will. You can edit to your heart's content after that.

8. If your Hero 6 footage isn't stationary (A cool ACTION motion video!) and not in a Gimbal, or has a lot of movement, I highly recommend trying out the proDAD Mercalli 2.0 Filter! (AFTER that lens correction!)

9. IF you want to try the Mercalli 2.0 Filter out (it works well for me w/ walking shots), use it the first time you do only a TINY clip of video in your entire timeline to see what settings work best for your GoPro Hero 6!! Try it in a running vid for 5 to 10 seconds only. Don't try it on a big file or a cut file initially as it takes a while to render the stabilized video and you don't know if the settings are good...you use a short clip initially to find the settings that works best for your footage. For my settings w/ fast walking, I choose Final Result (Compare View), Best Border (Border Handling), CLICK on "Further Settings," Click on EVERYTHING (Roll/Zoom/Horizontal/Vertical Tilt Compensation), Click OFF Rolling Shutter Compensation, and I increased my Avoid Border to 35%, keeping everything else the same. If the video all comes out weird, just change the settings a little at at time on the TINY CLIP until its perfected...should take 10 minutes, tops!!

Using EXACTLY the same settings above, here is a video of my family and I walking the Brooklyn Bridge in September 2018:

I SURE hope this helps a little. PEACE!!

As a suggestion, I set my GoPro Hero 5 Black so that I don't get the fisheye effect when recording.

Change the Field of View (FOV) settings to Medium, Linear or Narrow. Experiment to find which works best for you. Sometimes I get a little fisheye effect with Medium.

This way if I set my GoPro to record at 1080, the output will be 1080 quality. If you are using the lens correction in VS, then I would suggest that you should record in higher quality than you intend to produce the video at.

I would also suggest that you work out the focal length too. All action cameras have a fixed focus. This means that there is a sweet area where things are in focus and things aren't. For me, this is more important as I like to do some macro work when I diving. It's no good me getting to within 3 or 4" of something as I know it'll be out of focus when I see it at home. I mention this as your sample images of the pens are way too close. It is hard to pick this up on the LCD screen and even harder under water. I have to work based on the length of my hand and judge from there. I can also use the arms on my tray.
