Does anyone have a recommendation for a 3-axis gimbal for an Iris+?

The only option I have found out there is the DYS 3 Axis.  Are there any others that work with a GoPro Hero 4 Black?

Thanks, erik

p.s.

If someone who owns a DYS and an Iris sees this, I have a few questions:

  1. Does the DYS integrate with pixhawk?
    • Meaning in auto missions or follow me, will the Iris+ be able to tilt the camera up and down to keep the subject in frame?
  2. Is there an interface plate, or do I have to find someone to 3D print one for me?
  3. Does the DYS work with a GoPro 4 black?
  4. How are the vibration levels?
  5. Is it difficult to install
    • Complicated software config I can handle, but on the hardware side I'm pretty awful at soldering and tend to really mess things up.

LOL.  Thank you.

To be honest that was just a test video.  As far as color correction, I try to get by with the stock color board in Final Cut.  First I do exposure.  Within that I do the blacks first.  Then the highlights.  Then the midtones. If I need more control, I use Nattress Curves Luma.  Then I do the color.  For the most part I just try to get the white balance correct, or skin tones if there are people in the shot.  So basically I do a pass on all the clips to get exposure and color balanced out and corrected.  Others skip right to the grading.  Until last week when the color board was moved into Effects, I used an adjustment layer I created in Motion.  Its basically a title with no content.  i put that over the slip and then do any color grading to that.  In this video there wasn't a lot of color grading done.  I wanted to show my parents their farm (and the mountain) in different lights.  

As for sharpness, I almost never sharpen.  The image naturally sharpens up when you adjust the exposure.  What I do is shoot and edit almost exclusively in 4K.  When you shoot in edit in 4K, then export to 1080P, you get a better image than if you shoot in 1080P.  There is one sequence in that video where I shot in 1080P by mistake though.  Since it was just a test movie (mostly to show my parents their farm from the air), I used the 1080P footage anyway.  You can tell if you watch the video.  Its all the shots from the top of the mountain.

So my GoPro settings are 4K, 30fps, Wide, Protune, Flat Color (lately I've been trying GoPro color and liking it), Native white point.  I like using the native white point instead of setting it to 5500 because I want the GoPro doing as little processing as possible - just capture the data and record it at the highest bit rate possible.  

In this video, I also added some blur around the edges because I like the look.  And I guess I should mention that I letterboxes it - but thats kind of obvious.  There is very little slow motion in the video, I just fly super slow.  For example, the opening scene and closing scene look like they are slow motion, but they are at full speed.

Oh and one other thing.  I happen to like the look of fisheye.  Especially for mountainous and hilly areas, I think it looks good.  By the time I crop in the image a bit to reframe, or apply image stabilization (which crops in automatically), combined with letterbox... the fisheye is reduced.  I almost always try out a fisheye remover on clips, but never end up liking it as much.  Its different for more flat landscapes though.

Thank you for your reply.  This video editing is a new thing for me and a new software and workflow to learn.  I am extremely competent at adjusting still images in Lightroom but video has proven more difficult for me.  I have a hero 4 Silver, so I do not shoot in 4K as it does not have 30fps.  Of course you are using FC, and I have chosen Premiere as my home workstation is a PC.  Do you ever apply LUT's? I saw a video about adding a LUT to an adjustment layer to "fix" protune videos.

In general I do not apply LUTs. Mostly I do it by hand. I do use filmconvert (but not in the video you are looking at). I might apply a LUT depending on what look I am going for.

There is nothing wrong with 4K at 24 fps. Combine that with a 23.5 Letterbox and you get a very cinematic feel.

I believe the iris was on it's own from about 22 seconds to 52secs, that is I let it go where ever the wind took it without any interference from me on the controls whatsoever 

I just discovered this topic while looking for the best upgrade from my Tarot T-2D to a 3 axis gimbal, and the only two choices I was aware of were the DYS and the Feiyu. It looks like there's a new player now: SteadyGo http://xproheli.com/products/new-steadygo-3-axis-high-torque-gimbal...

Has anyone heard about this gimbal or found demo footage yet? It claims to be high torque, and looks nice - but I haven't seen any footage yet.

I only noticed that someone mentioned they no longer handle the DYS and at the same time this model was listed

This whole post has been really informative. I an a newbie with the Iris+ and UAV in general but not with video production.Trying to learn as much as i can and slowly getting better at flying. I need to add aerial footage to my reel and I would like to find an optimal solution for a gimbal with the Iris+. Looks like XProHeli is the way to go but no more DYS gimbals. So just to keep this thread going, has anyone tried that new SteadyGo gimbal from XProHeli? I will be contacting them after i write this. 

I would really like to see some video results from the XProHeli SteadyGo 3-axis gimbal (I've searched YouTube and have found none).

I've watched a lot of videos from guys on the RCGroups forum using the Feiyu Tech G4, DYS, and Align G2 3-Axis gimbals.  All of them seem to suffer from some level of horizon drift when turning during forward flight motion.  I think a lot of it has to do with a lack of a communication channel between the flight controller and the gimbal controller.

As I have mentioned above in this thread, I own both the DYS 3-Axis and the DJI H3-3D gimbals.  My biggest complaint with my DYS gimbal is that it suffers from YAW drift during forward motion of the multi-rotor (where as the horizon is solid).  My H3-3D on the other hand is rock solid in all three axis during various flight maneuvers.  Perhaps the H3-3D is more solid due to the CAN bus comm connection between the Naza V2 F/C and the H3-3D GCU, I don't know.

I am thinking I might be able to improve my DYS performance with my Pixhawk controller if I were to use the AUX channel outputs between the F/C and the gimbal controller.  Right now, my DYS gimbal controller is free standing, and pitch is controlled by a spare channel on my S-bus Rx.  I've spent hours trying to tune my DYS, and others on RCGroups have just given up on the DYS.

It will be REAL interesting to see the video results of the SOLO with its 3-axis gimbal!  Though I don't usually like the "boxed" solutions like the Phantom, Inspire, or Bebop (or Iris for that matter), the SOLO looks really cool, and pre-sale videos seem to look pretty awesome.  And I really like the programmability of the 3DR flight controller (it's the one reason I haven't pulled it off my big hex with the DYS gimbal).  I'm ready for my next aerial video platform...

Thanks for the reply.

I haven't found any videos yet although their website is www.steady-go.com and they have a DSLR gimbal. The video is from 2013 and nothing coming up in Google searches? The smaller drone gimbal must be really new.


I have only had my Iris+ a few months and it was having all kinds of issues at first when i tried to use the GoPro mounted on front. Not sure what the deal was, it flew fine without it. After horrible support lag from 3DR, i basically fixed it myself by doing many many calibration attempts and complete resets. I think it might have been APM Planner for my mac after i did a firmware update. I now use Mission Planner with VMWare Fusion. So i have been worried about throwing more money at it if its going to have more issues. Its been flying fine now though with the front mounted GoPro. I still need a gimbal and FPV setup. And the SOLO is so new that i don't want to go that route either. But i need to get a solution soon. I think i might just buy the Phoenix Simulator software and get better at flying first and then wait for more of the SOLO issues to get resolved. I was thinking about the Phantom 3 but not too sure about that camera. Although it does say 50-60Mbps for the bitrate. 

I wish XProHeli would do a sample video with the Steady Go. You'd think they would have one already if they wanted some sales. 

It's possible that when using the front mounted GoPro on the Iris that the balance (CG) was off, contributing to flight instability.  I find that both my Hex (using Pixhawk) and my quad (using Naza V2) fly much better when I use the battery to counter-balance the weight of the gimbal and camera (I just mount the battery further back with Velcro and a Velcro strap).  It will be interesting to see how the Solo performs with a fix-mounted battery (and no way to compensate for the forward weight of the gimbal / camera).

My buddy has a Phantom 3, and I must say the video (link to ground station) is pretty awesome at 720 res. and DJI's camera shoots some really nice footage at 4K / 30FPS (or 24, I don't recall exactly).  And there's no fisheye either (but that can be handled on GoPro by going to the "Narrow" field of view option).

My only comment on 4K at 30FPS is that it (GoPro) doesn't respond well when the camera rotates quickly, the video gets a little choppy at 30FPS.  At least at 2.7K, you can record at 60FPS, which is best for an original source video, then edit as needed.  Not sure if the P3 camera has that option.  As far as bit-rate, just be sure to get a SD card that can handle the dataflow - Sandisk has several mid-priced cards that perform very well.

Yeah, the CG might have been off, but they did have sample 3DR videos that showed a front mounted GoPro with the clear plastic housing. I just bought a frame housing and that was ok. Both pointed forwards and downward. But that was just for testing, i need a gimbal now. Or a SOLO or P3. I would really like to check out some raw original files straight off the P3's camera (No YouTube/Vimeo compression, etc). And that Narrow FOV is somewhat OK but i would prefer to have it a bit wider than the 94 degrees or so. The P3 cameras 4K is only 30fps.

When filming i would try to keep movements to a minimum. Just slow flying and slow camera movements. Looks a bit more cinematic anyways and you wouldnt have to slow down any footage. Erik Graham in earlier posts had a great video in the snow. Trying to minimize stuff done in post. 

For my GoPro i have the SanDisk Extreme Pro 64Gb card at 95MB/s. "Should" be able to handle any of the GoPro 4 Black settings.
