DIY Variable jello remover filter

Hey there Peeps, this is a small tutorial on how to make a variable light input filter to get rid of the jello produced by the rolling shutter on the GoPro Cameras.

The main advantage is that you can change the amount of light the sensor receives simply by adjusting the lense.

 

First what you are going to need is a RealD3D glasses you get on the cinema when watching a 3D movie.

 

 

Then, carefully, separate them from the lense, they are glued together, a bit of force is required, dont worry the lenses are plastic they wont break.

 

Once you have them apart, you will need to find the right position for them, only one will work, you will know you've done it right when it looks like the following video with no weird colors.

 

 

 

After this you'll need to cut them into your desired shape and size, it can be circular so you can adjust it on the go.

In my case, i've got the Spidex v2 gimbal, so its easy to swap them, i did 3 front lenses at diferent angles so i can adjust the light. 

 

 

 

Here is the finished set of lens.

 

 

Hope this works for you as well as it did for me, as always milage may vary, always balance your props and motors.

This is a vid showing the end result, thanks!!

Interesting, polarizers. So do you place one in front of the other, then rotate one with respect to the other to reduce the light input to the camera, effectively stopping it down and thereby reducing the shutter speed?

That is exactly how polarized lenses for cameras work so no rocket science involved.

I bought a 52mm filter and mounted a servo to rotate 1 of the lenses - works great - but the servo needed more travel.

So this allows you to get a better picture when you are in a really bright location? Could you to a video with and without the polarized lenses to show the difference?

Oh, just looked it up. I see the difference now. It's the wavy stuff in really vibration heavy videos.

yes even with full sun you wont get jello, some ppl also gets good results with ND filters but the advantage with this one is that you can adjust them to your needs.

You could just use a better camera than the Gopro, like the sony or the contour..

Sorry, I think the GoPro beats both of them especially the 3 black edition even if it has jello at times.

I agree. The GP3Blk is miles above the Contour and/or the Sony.

Every one of my HD videos was shot with the original Contour I bought for $100. They are now out of business due to Gopro's marketing, even though they had the better product. Tougher lighter and imo, shot better video. Not to mention it's profile is aerodynamic. The GoPro is only one HD camera guys, it's not the end all, be all of cameras, sorry. They just have strong marketing, look how well it worked fanboys...

Hmmm better than GoPro. IMO The audio from the Contour sucked and the profile would be almost impossible to mount on any existing gimbal. They failed as company because they didn't listen to their user base.

Nice work on finding a cheap way on making a variable nd filter. For those that don't know how it works it basically cuts the amount of light reaching the sensor therefore lowering the shutter speed of the gopro. Higher shutter speeds means less motion blur but more jittery and jelloy video.

I own a GoPro 3 Black and actually have never been impressed with the video I have gotten out of it. In fact it sits on the shelf while my Mobius is used as it is lighter, way less expensive and to my eyes shoots better video. Besides why risk a $400.00 camera in the air when the Mobius is as good as it is?
