CAMETV 7800 Gimbal Tricks – How Stable Is It?

Earlier today I had a comment about the CAMETV 7800 Gimbal and how people may want the 'camera over handles' mode. In this mode you don't have to raise your arms very high and will have less fatigue. Not exclusive to the 7800, any 32 bit Alexmos / Basecam gimbal can perform various positions and remain incredibly stable. In this video (below) i'm demonstrating just how stable these gimbals can be with the right configuration.

Now I realize the DJI Ronin is the best bang for the buck and it is an amazing system to carry heavy payloads. The main reason I use other gimbals is because i'm typically working with smaller cameras. I don't need to travel with the bulk, and I don't need to run around with the weight of the Ronin. If you watched the video above, you can see how even me (small guy) can man handle these all carbon fiber gimbals with just one hand [try that with a Ronin]. Even while switching through all of the different positions, the 7800 remained completely stable.

With this stability in a sub $1300 dollar gimbal like the 7800, you can see why it's really hard for me to go with a heavier gimbal like the Ronin. Unless of course there's a need to carry such a heavy payload, i'd rather just borrow a friends or rent one. Otherwise i'm happy to work with a more convenient system. As you can see in my video i'm using a heavier Canon 5D Mark III with Sigma Lens. If you're shooting with a GH4 or Sony A7s, these smaller lighter gimbals should make your life much easier when you have to pack, travel, and shoot all day.

Now the tricks I show on the CAMETV is not limited to nor exclusive to the 7800. Any gimbal running the new 32 bit software that has a properly balanced camera can operate just the same. It's extremely time consuming, but i'll try to do more videos on showing you a step by step process on balancing soon, but if you guys have any questions let me know.

    @Wheeler - If you know how to use the software, try going into the RC tab and change the RC settings for Pitch and Yaw to 'No input'. This is a test to see if your joystick is bad and is causing this problem. There are so many variables, that I would suggest starting the troubleshooting with CAMETV support, they will be able to walk you through different checks to narrow down what the problem could be.

  2. I have a Came-TV 7800 and balanced it and used it for a month and it worked fine. I have never changed PID settings. Now it shakes when tilting and using the pitch motor. Please see uploaded video for example of problem.

    Any advice would be greatly appreciated.

    Thanks and great work on all your gimbal posts.

    Hey Emm. I can't find the answer anywhere. Will the honu cage for the gh4 fit inside this gimbal? and will it work with the quick release plate from the kamerar qb-15?

    @Dave - You download the latest firmware and then you'll have to configure the software yourself to how you like it. I think the 'latest' firmware may support inverted mode if you power the unit off, rotate the handles, and then power it back on. If the gimbal is still struggling, then you have to retune your PID settings.

  5. Thanks Emm! I didn´t tilt the gimbal in the film... but I could do so without yaw arm moving (camera panning). Will try again. Regarding the firmware (I use SimpleBGC v2.42) and profile settings, can they be dowloaded or do I have to make them myself?

    @Dave - First up, I don't think you balanced the Yaw tilting the handles sideways and over the camera. If you don't have that balanced, then the gimbal will struggle. Second, I was able to do it because I had mine perfectly balanced, but technically you aren't supposed to be able to go 'inverted' on the fly. You need to make sure you're using the proper firmware installed and configured to where you would flip the gimbal and then turn it on. It will auto detect the inverted gimbal and then attempt to operate normally. Otherwise there's also a profile setting you can choose that you need to switch to before you go inverted.

  7. Hi Emm, I don´t suppose you would have a clue as to what is the fault with my CAME 7800. It won't work over the handles, with my 5D+16-35, the gimbal starts to wobble as soon as i tilt it. As in this video I sent them (first minute only shows that it is properly balanced). https://www.youtube.com/watch?v=UmTQ9Dvocl0
    When I tried with my Canon 550D the motor starts humming and hissing really loud as soon as I put it over the handles.
    CAMETV say I shouldn't be using it over the handles... But if I really had to, then invert the camera and put the pan bar back to front. Like in this video they sent me; http://v.youku.com/v_show/id_XODcyOTUyNzk2.html
    For some reason this works with my 550D, but it seems really stupid since the gimbal gets unbalanced + it won´t do for my heavier 5D. Would really like fix it. Any idea what to do? PS. Love you blog, been spending at least a few hours a month on it the last couple of years :-)

    theIdol, I just got my 7800 and had the same thing with the roll bar. I also notice that the back post was a bit off angle so I had to play a bit to put it kind of straight.

    Thank you Emm for the tutorial there is maybe one small detail that you did not elaborate to help with the balance,since i had problem to balance my Sony A6000 with a Sony 18-108mm until I move the bottom part ( where the QR plate sit ) up . That was a lot better. I still have some minor adjustment since the frame was not i a perfect alignment from Came but so far so good !!

    @theidol - The angle of your arms will definitely effect your balance. Try to make it as square as possible.

  10. theIdol

    Ok, it's very possible I am confused. I thought the roll & tilt would be adjusted by the QR plate and not adjusting the roll bar in the back. In my case the roll bar was loose and pointing down without a camera even on it, So I needed to lock that down first before and other adjustments. Which was different from your video. When I look at the roll bar from the side the bar with the motor on it is slightly angled up a degree or 2 compared to the other side with the bearing on it. I think that might be impending my efforts to balance this.

    @theIdol - I think you're confused. The unit does not come pre-balanced. It only comes 'pre-configured' in the PID settings. You need to walk trough the steps of balancing for your camera and that is why they left the items loose.

  12. theIdol

    I just got my 7800 last week and mine sure wasn't the same as the way you got yours. Both the yaw and roll bars were completely loose in fact the yaw bar was almost out of the 2nd retainer. As a gimbal that was to be balanced at the factory this sure isn't it. Even the QR plate is trouble, seems like a soft metal. When I tighten down so the camera doesn't rotate it puts major groves in the plate. I have been struggling for 3 days to get this balanced and so far no joy.

  13. Can anyone here please help? My 7800 will not hold the horizon level. I have contacted CAME they sent the gimbal software and a quick video on how to re calibrate. The problem is My Mac or my PC will not connect to the software. I'm at the point of send this back. Any help would be great.

  14. I think it was because the rokinon 35mm f1.4 is so long and heavy. I found the center of gravity and put it there and didn't go by the gimbal leaning forward or back and its not doing it anymore.

    @AO&JO Photography - I'm not super clear about the problems you are having. A video would help alot. When standing behind the camera, the pitch motor should be on the left side of the camera. Do you have it backwards or upside down when you balanced? Did you change anything in the software for sensor positions?

  16. My camera right to left movement is balance I can lean it back and it stays in position so my pitch is balanced. It no longer swings when I lift a handle off the stand so my yaw is good to go. I powered it up and I had held the joystick in I didn't know what calibrate ACC meant. Now my camera seems to be balance but keeps turning upside down so basically the bottom rail is at the top position. Help please? The roll bar is suppose to be at 90 degrees correct?

    @Jeff - It would work (if you can find a way to mount it) as a pan tilt head on a jib. These gimbals are designed so you can plug in an external RC remote for second operator mode. The only thing is you would have to open up the case that hides the controller to attach the remote's receiver and you won't be doing 360 spins, just 180 angles.

  18. Jeff

    How well would this work as a light weight Pan & Tilt and the end of a Jib/Crane? I was thinking the joystick control could be moved to the operator end. Would it be able to perform smooth slow start and stops for pans and tilt? How would it compare to you Servo City system you were using?

    @ghost99 - Yes they have a generic profile setup to work with that size camera, but if you take the time to learn the software you can tune it for many other cameras and other weight.

    Hey Emm,

    Quick question - on their site it states the following:

    *** 2-We have set up PIDS before shipping , it can work with different camera directly, just like 5D3, 5D2, 7D, GH4, and Sony A7 ***

    Does this mean it can also support the Canon 60D? I just wanted to verify this before purchase

    @Apostolos - Off the shelf it's a great kit and mostly configured. But with any gimbal you still have to learn the balance dance and eventually some software tuning - even with the Ronin. I myself have been building custom ones for different purposes, but for an off the shelf solution under 1400, I recommend the 7800. If you want more convenience features you would have to pay more.

    @Apostolos - I doubt that is a real Gini website. Gini only makes Rigs not cranes or stabilizers. I heard there was some weird falling out with a partner site and it's still a mess. Whi knows.

    That listing also has no battery, means no charger, and you have to assemble it from scratch. Doesn't come assembled like the one i'm showing in the article with battery tray and monitor mount. Doesn't have the new QR baseplate system too that makes it easy to balance.

    It's about 70% of what you need to start flying, which is easy once you learn it and know what extra parts to shop for, but tuning, assembly, and balancing can also be the hardest part for new owners.

    What's supposed to happen after a "long click" of the joystick? (Click and hold the joystick button for longer than 5-seconds.) Mine beeps ~10 to 15 times then all the lights flash and turn red. The gimbal then stops responding to any joystick commands or movement. I have to power it off and back on to reset it. Is this normal?

    If I'm not mistaken I believe this "mode" does a "Calibrate Accelerometer". Anyone have any experience with this?

    I took my 7800 out on a boat today on Lake Havasu. The 7800 performed amazingly. It was like it was on a tripod on solid ground, and I was on water, handheld. The horizon was rock solid. I can't believe how nice the footage looks. Panasonic GH4 in 4K UHD.

    I supported the 7800 with an Atlas single rod system [ http://www.atlascamerasupport.com/1-rod-packages ] that we've owned for many years but have barely used.

    It holds the 7800/GH4 combo like it's weightless. It is a bit of a pain to have the single rod bonking me in the head.

    I'm playing with the idea of bending a piece of 1/2" EMT conduit, placing it in the pockets of the Atlas vest and hanging the 7800 via a bungee cord.

    Also, my SmallHD DP4 with its loupe attached is the only way to see the image in daylight. It works quite well when it's mounted on the 7800's monitor mount. Good to evaluate exposure, framing and focus.

    7800 is amazingly stable, even going over severe wakes handheld. Amazing. Rock Solid.

    The socket screws that attach the yaw arm to the upper frame on my 7800 have 2.5mm sockets and a thread pitch of M3 x .50mm.

    These are the silver socket screws that are 40mm long measuring from under the socket head to end of threads.

    As for shipping time, mine took 20 days from the day I placed the order, but to be fair I was on Pre-Order status at first and then the Chinese national holiday from Oct 1-7 stopped all work. Once it actually shipped it got here remarkably fast: a few few days to arrive in California.

  26. Hey Emm
    Have you tried to use the Winbook TW100 10.1 as a field monitor for your DSLR? I see you used it to tune your motors in the 7800 so it should work right?
