Gopro Shaking


Recommended Posts

I shot my first GoPro video using a HERO3 mounted on the tail of my bike. I am a bit disappointed about the shaking of the camera, in facts anything above 60mph is unwatchable. Here's an example during the warm up lap at Thunderbolt: https://youtu.be/zXmRmhT1jrU

 

Any idea how the camera should be mounted on the tail of the bike? I used a sticker mount.

the vibration in the bike and from the wind is really unavoidable, keeping the connecting pieces between the mount and the camera to a minimum helps.

 

Have you tried using You-tubes stabilize option ? makes the videos much smoother, but can cause the picture to distort slightly in some places

I have seen worse. Heck I have filmed worse myself.

 

I have found in my own personal experience the heavier the mount the better the video. I use RAM ball mounts that are solid mounted to the bike. Here's a photo of the camera on one of my bikes. The camera is attached to mount that goes into the steering head bolt. It's also useful for mounting other things such as GPS's.

For the rear RAM sells a ball mount that can be attached to a license plate bolt or another fastener.

 

Amazon has a pretty good selection of RAM mount stuff. You can buy the pieces individually to build your own mounting system.

I see what you mean. Like Tyler, I have shot much worse video myself using a ContourHD1080 camera. My finding was that it was due to the fiberglass fairing vibrating a lot and the camera was attached using a suction cup to the vibrating fairing.

 

I was thinking that maybe that the fairing was vibrating could be your problem. Is the fairing well affixed to the frame?

Looks like the state of the art for prosumer mounts is the FeiYu G4 ($350): http://www.feiyu-tech.com/G4-en.php.

Another prototype you can get for $200: https://www.indiegogo.com/projects/slick-stabilizer-a-motorized-gopro-steadicam#/story

 

As for stabilizer software, I read that iMovie does a good job. Adobe Premiere Warp is the best. I'm going to try tonight and show some before/after with iMovie.

T, actually the youtube stabilizer is not bad at all. The picture above 50mph is much better. There is still shaking at the apex but I guess that's too much to handle for any software. Same clip after correction: https://youtu.be/qWM-MUcb-pc.

 

BTW, I wonder why I have so much tail shaking in the corners at less than 60mph (and less than 45 degrees angle, I don't remember dragging the knee in any turn during that lap). I guess the gyroscopic forces and acceleration at the same time? Or could it be something with my setup?

Spaghetti,

 

How is the camera attached to the tail unit? I have found that the suction cup & arm I use makes the video very prone to vibrations. I will be doing some tests, but right now my gut feeling is that the better you can lock the camera down (ideally with a flat mount on the fairing or all the way to the seat unit subframe), the less vibration you'll have.

I just watched Dylan Gray's lap of SIlverstone, which is filmed with a host of GoPro's. In some of the shots you can see the other cameras (like in the attached screenshot) and it looks very much like that they're using their sticker mounts.

Nylox was MotoGP cam before, I guess GoPro has taken over. I can see one camera mounted on the bike tail and pointing at Dylan's back. Would be curious to see the other mounts and if they processed the footage with a stabilizer. Picture is very stable.

 

I just finished processing my test clip with iMovie stabilizer at 50%. It does a good job removing the vertical shake but doesn't seem to do as well for horizontal shaking. It's more apparent on the straight before the last turn at 1:50. Still better than the YouTube stabilizer: https://youtu.be/QbsSKWVyXSA.

They have professional level post production so that helps,

 

I'm gonna guess they use some kind of stabilizing software that reduces the FOV as part of the process to eliminate the flicker and distortion you get with the YouTube or iMovie one. Reduce the visible part of the frame and you can shift them into alignment without skewing the picture to make it fit

 

I'd also be very surprised if the cameras weren't solid mounted to frame and other hard parts

I have a GoPro and found out that the shorter the bracket, I get less vibration, which is logic. Even if I put it on the tank cover which is not solid and it does vibrate I have more than acceptable results even in very bumpy tracks.

 

If you want even better results then you should go for image stabilized action camera like Sony and no more hard shacking.

Have to agree. The lower the center of mass of the camera the less the mount has to deal with shakiness. Mounting it to hard stuff helps too.

 

Here's a video I on-board a friends bike using a RAM steering head mount just like the photo I posted earlier. He's going a bit slower than normal because it's 48 degrees out. :)

Yes, thanks for the tip. I figured the tail fairing has more shaking leverage than the triple-clamp, similar to what you say for the mounting bracket.

Nice sound work, what camera and software did you use for the lap time/tracking layout?

I thought all action-cams have hardware stabilization. Is it Sony better than Gopro at this?

Wow, picture is very good. 60fps seems to do a huge difference. Which camera did he use?

That's the same Contour +2 camera that I use on my own bike. Just moved it on to his for a session.

No I believe only Sony has the image stabilization for the moment. I used dashware for the track and time layout.

Speaking of Dashware (which I really like), I have gotten confirmed from GoPro/Dashware support that DashWare doesn't support 4K video at this time.

Update: I borrowed my friends GoPro again today. This time, I mounted it using GoPro's "flat adhesive mount" and it did WONDERS to the quality of the video - the shaking was virtually all gone! I'll upload a small sample when I have the time.

Today's Room For Improvement is to use a slightly higher Quick-release buckle so my steering damper doesn't take up ~1/3rd of the picture :)

So after reading @Drloannis comments about the as200v I had to try one. This is a video using the same mount than the others with an adapter gopro-to-sony. Few comments:

 

- stabilizer works very well at low speed, after 50mph I don't see any improvement compared to gopro

- picture quality is excellent on the as200

- the wind noise reduction filter cuts the engine sound so avoid

- the mount I'm using has a hard rubber base which might wobble the camera, I'll have to try a rigid plastic mount
