Review: Beholder Lite Gimbal For DJI Phantom Quadcopter

I recently purchased a Beholder Lite camera gimbal for my DJI Phantom quadcopter, and I am very pleased with it. Bottom line for those that don’t want to read this entire post… The Beholder Lite is hard to beat for the price, as long as you have some time to tune the gimbal.  Output video is very steady when flying reasonably, and still images are far more crisp than they are without a gimbal. The final output is not quite as good as the H3-2D Zenmuse, but it is still much more than acceptable. Plus, you can buy almost 4 Beholder Lite’s for the cost of one Zenmuse. However, when flying aggressively, there is a lot of vibration. Read more for an explanation, pros & cons, plus tips for set up and some sample videos.

Background

Um… What is a camera gimbal?

First, a gimbal is: “a pivoted support that allows the rotation of an object about a single axis. A set of three gimbals, one mounted on the other with orthogonal pivot axes, may be used to allow an object mounted on the innermost gimbal to remain independent of the rotation of its support.”

Basic Gimbal (photo: Wikipedia)

A camera gimbal is a set of these gimbal supports that enables the camera’s movement to be independent from the support structure. In this case, the camera gimbal allows the camera’s orientation to be independent from the orientation of the helicopter. Check out this video for more detail:

The Beholder Lite Gimbal

The Beholder Lite gimbal is a direct-drive brushless gimbal. This means: 1) the motors are brushless motors, and 2) that the motors directly drive the support arms for the gimbal; there are no servo arms or other moving parts in the gimbal assembly. Brushless motors are faster than traditional/brushed servo motors, so they offer a smoother response and better stabilization. I have used the Phantom with no gimbal, as well as with a brushed/servo gimbal, and the brushless direct-drive gimbal is by far the best quality.

I mentioned that I am very happy with this gimbal, though it has not been without its own hiccups.

Pros:

  • Very stable footage ****once properly installed and tuned****
  • Still images are more crisp
  • Videos are far more stable, though aggressive flying will cause significant vibration (this happens with all gimbals, though some more than others)
  • Very affordable compared to similar gimbals on the market.

Cons:

  • Installation instructions are not very good. They are based on pictures only, and do not clearly identify motor orientation or wiring. I originally had the motors in the wrong direction, and the motor polarity reversed. This third-party post (with video) was very helpful for installation. I’ve provided additional installation details at the bottom of this post.
  • The gimbal is marketed as “ready to go” – you just assemble it and start flying. Once assembled, I had lots of vibration to the point of being unusable. I seriously considered returning it. However, I had to manually change settings before I could get some decent footage. This was both physical (in the mounting), and in software configuration. I had to adjust the output gains before the gimbal would provide stable footage (details below).
  • The vibration absorbing mounts are too soft. You will get vibration from the camera oscillating below the copter. Luckily this can be corrected but sticking some foam ear plugs inside the vibration mounts (see details below).

Both aggressive flying and high-wind environments will cause additional vibration in both the copter and gimbal, so keep those in mind when you are filming. 

Sample Video Footage

I still don’t feel like I have the gimbal settings (gains) 100% dialed-in, but I have it close enough to get some high quality footage. I have found that the 1080p@60fps video mode on the GoPro camera has the best results. 2.7K@30fps has too much rolling shutter effect for the footage to be really usable. I also have not balanced the propellors on my copter, which will also help to eliminate vibration. Here are a few samples from the camera/gimbal combination. All of this footage was captured with a GoPro Hero 3 Black Edition.

1080p@60fps with Post Processing via Adobe Premiere: I still think I can get it more stable by changing a few editing parameters and changing the sequence of my scaling and effects, but I am very happy with this output.

1080p@60fps Non-Stabilized: “Day for night” color correction, non-stabilized, GoPro with ND filter, just for fun…

2.7K@30fps with 10% Warp Stabilization The footage is far better than it is without a gimbal, but there’s still some rolling shutter effect evident (capturing Tony’s hex liftoff).

Aggressive Flight: This footage is completely raw, without any post-processing or stabilization. This shows output when flying aggressively. This was *very* aggressive flight – full speed in ATTI mode. I recommend that you *never* attempt to shoot professional footage flying like this:

Sample Still Images & Compositions

Here are just a few still images and compositions captured with the Beholder Lite gimbal. You can see more on my Flickr page.

Installation Details

In addition to the gimbal’s manual, I strongly recommend that you read both of these posts and watch the videos for detailed installation instructions:

Pay particular attention to motor orientation and wiring. The motors look symmetrical, but their weight and operation is not. The pitch motor should have the wire coming out the side that is closest to the copter. The roll motor should have the wire coming out the side closer to the camera. If you have your motor polarity reversed, you’ll know b/c the gimbal will vibrate back and forth. This won’t hurt it, and you can just reverse the wires easily if this happens. In the picture below you can see my motor orientation:

Motor Orientation and Wiring

Motor Orientation and Wiring

Very important: make sure your gimbal is balanced. If the power is off, the GoPro should not fall in any direction. It should just stay where it is. Having it perfectly balanced is key to having smooth footage.

The rubber vibration dampeners are too soft for the gimbal. If you fly it “stock”, you will get a TON of vibration from the gimbal oscillating under the copter. Use some soft foam earplugs, roll them up, and put them inside of the dampeners. I used the cheap foam orange ones you get from any drug store, and they work great. I put one in each of the 6 vibration dampeners. Another picture below, so you can see the orange ear plugs in the dampeners:

Earplugs to Stiffen Vibration Dampeners

Earplugs to Stiffen Vibration Dampeners

Once your gimbal is powered up, if you have vibrations while the copter motor isn’t even running, then you need to adjust the gains and tune the gimbal itself. I had to do this. You can connect using a standard micro USB cable (from any Android phone), and use the software here: https://code.google.com/p/brushless-gimbal/downloads/detail?name=BruGi_049B_r161.zip&can=2&q= and drivers here: http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx (windows only)

Not entirely necessary, but I also put Moongel in between the gimbal and the copter body to absorb vibrations, and I also put it on top of the gimbal’s gyro board to absorb vibrations that may affect gimbal orientation (see picture below).

Beholder Lite on DJI Phantom

Do not get the white wires too close to the power wires or to the motors. They are very light weight, and can get interference from power wires, motors, and motor wires. You will get inexplicable vibrations if this occurs.

One last thing… If you use zip ties on the gimbal for extra safety, keep them very loose. If you compress the dampeners, the bottom plate will hit the controller board, and cause significant interference with gimbal operation. Everything will be fine one second, then completely out of control the next.

Battery Life

Before having a gimbal, I could easily get 12+ minutes of flight time per battery. With a servo-based gimbal, I could get about 10+ minutes per battery. With the Beholder Lite, I get a max of 8 minutes per battery. I set a timer for 7 minutes, and be sure to bring it down as soon as the time goes off. However, this seems comparable to battery life with other brushless gimbals that friends/coworkers use. The decreased battery life is due to additional weight of the gimbal, plus the additional power consumption from the gimbal motors.

Recap: Russell Brown’s Top Gun Flight Training at Photoshop World

Last week I had the opportunity to feed my obsession with aerial photography and participate in Russell Brown’s Top Gun Flight Training workshop at Photoshop World, and it was an awesome experience! Many thanks to Russell for putting together this incredible workshop. There’s nothing like a giant room full of RC photography enthusiasts, with multiple copters flying around all over the place, coupled with a wealth of Photoshop and video processing knowledge (links below for all of this content)!

There are few places that have as dramatic architecture and landscape as Vegas, and this also made for some great photos.

The day started with an intro from DJI, who sponsored the event and donated copters for workshop participants to use.  If you haven’t seen their copters/footage yet, you should check out the short video below to see what’s possible with today’s radio controlled aircraft.

Next, we broke off into teams to cover basic flight training principles… everything from safety (the most important thing of all), basic takeoff and landing procedures, flight modes and capabilities, to techniques for panoramas and dramatic shots.

Once everyone had a chance to fly the copters and get acclimated, we regrouped to learn how to work with your aerial footage. Do not miss the videos from Russell Brown and Colin Smith in the links below. These are must-watch content for any aerial photographer, cinematographer, or GoPro enthusiast and contain a wealth of information!

Finally, the day ended with a flying competition… The person who could fly through 4 hula hoops without knocking anything over, without crashing, and land in a controlled fashion walked home with a brand new DJI Phantom, and the winner did it in 26 seconds! … This was not an easy task.

Some additional photos from the event…

Lens Profile Correction for GoPro Cameras

Last week, new release-candidate versions of Camera Raw and Lightroom were posted to Adobe Labs that feature additional camera and lens support. I was extremely excited when I found out that one of the new camera profiles supported is the GoPro Hero 3. I’m a huge fan of GoPro cameras, and this means we now have more ways to get more creative with their usage.

gopro_ps_lr

I have a GoPro Hero 3 Black, and I use it in lots of different situations… everything from mounting it to a surfboard, attaching it to a remote control helicopter, mounting it on my car, to weird perspectives snapshots of everyday life. I love the camera, and am always finding new/creative ways to use it.

I was recently thinking… I absolutely love the shots I get off of the GoPro, but I wish there was an easy way to reduce the fisheye distortion. I wanted to try my hand at creating some aerial panoramas, but the distortion was causing issues. You can reduce the distortion using Photoshop’s Adaptive Wide Angle filter, but that can be tedious to get right. This release makes the process of reducing fisheye dead simple.

Reducing the lens distortion is now as simple as selecting the GoPro camera profile in Camera Raw’s lens correction settings, and you can use it to create some incredible images. Check out the video below to see how to apply GoPro lens correction to both images and videos in Adobe Photoshop, Adobe Lightroom, and Adobe Bridge.

Here are some side-by-side comparisons of before and after applying the GoPro lens correction.

Panoramas

I’ve also been able to use this feature to create some awesome (in my opinion) aerial panoramas using the DJI Phantom quad-rotor remote controlled helicopter. The easiest way to create one of these panoramas is to select the images you want to merge inside of Adobe Bridge. Then right-click and select “Open in Camera Raw…”, and then apply the lens correction to all of the images. Once you’ve done that, keep the same images selected and go to Tools -> Photoshop -> Photomerge inside of Adobe Bridge. This will launch the Photomerge process inside Photoshop, and after a few minutes, you will have a nice panorama to work with. Take the generated panorama, turn it into a smart object, and then you can start applying other filters (including Camera Raw) to it, and you can achieve some great results.

Here are a few panoramas I’ve created. Click on any one of them to view an interactive panorama, where you can zoom into the full resolution of the image.

Salisbury, MD (5392 x 1833) – Click for Interactive Panorama

OBX-photomerge

Avon, NC (6623 x 1533) – Click for Interactive Panorama

To make the panoramas interactive, I used Photoshop’s “Zoomify” export, combined with the Leaflet mapping library for an interactive HTML experience. You can ignore the HTML it generates, but keep the images and XML configuration file. I then used this open source Zoomify Layer for Leaflet to make the images fully interactive, without any plugin dependencies. You can pinch/zoom and pan the images, and they are loaded as individual tiles, so it’s a smooth experience for the end user.

Next Steps

Go get started, and have fun! You can download Camera Raw 8.2 and Lightroom 5.2 release candidates from labs.adobe.com – just make sure to get the correct Camera Raw plugin for your suite (CS6 or CC).

My New Obsession: Aerial Photography & Creative Cloud

I have a new “hobby”, and I must admit, I am completely addicted. Perhaps “obsessed” might be the proper term. Luckily for me, it is a great use of Creative Cloud, so I can get away with it! What is this new obsession, you ask? Aerial Photography.

However, I’m not flying airplanes or riding in helicopters. In fact, my feet aren’t even leaving the ground at all… just my camera. It all started a few weeks ago when my friend Tony approached me about getting some aerial photos for experimentation. He knew I already had a GoPro camera, and that I was completely obsessed with it… GoPros take incredible pictures, and are very durable. The only thing was that we needed a reliable way to get it off the ground.

Enter part 2 of the equation, and the greatest part of my obsession: the quadcopter.  Basically, it is a multi-rotor remote controlled helicopter. Multi-rotor copters are mechanically very simple, very stable, and versatile. Just check out this TED video to see how agile and versatile they can be.

I had been wanting one of these for a long time. Researching here and there, looking at the DIY and pre-built kits. I wanted something that would be easy to fly, but also capable of outdoor flight and a camera payload. Copters can range from inexpensive children’s toys to high-end hex/octo-rotor professional rigs for many thousands of dollars, and I looked at nearly every one of them. I finally settled on the DJI Phantom.

DJI_Phantom

I chose this copter mainly for two reasons:

  • It has a GPS guidance system that makes it easy to fly, corrects for wind drift, and even has a “return to home” feature if the battery gets low or if it loses contact with the controller. Yet, it can be very maneuverable and agile. 
  • It is easy to setup, and comes with a GoPro mounting system.
  • The videos that people are producing with this setup will make your jaw drop. (Yes, I said two… this one isn’t an “official” reason.)

DJI’s promise of “ease of use” definitely holds true. It was setup and running very quickly, with the longest part of the setup process waiting for the battery to charge. Once we finally got it off the ground, there was no going back… Now, with everything that I look at, I wonder “Wouldn’t that be cool to take a picture of from the air?”

A word of warning, once you start down this path, it is very easy to become obsessed – I will elaborate more on this subject in a bit. For now, check out some of my recent photos with this rig. You can see the full collection (and any future photos) on my Flickr photostream.

In fact, we were so excited to fly it, that we didn’t even wait for daylight! The Phantom has a series of LEDs for navigation, so there was no problem flying at night, at all. Here’s a short video from my first quadcopter flight:

While this setup takes amazing still images out-of-the-box, you may have noticed that the video isn’t all that smooth. Some of the shaking can be reduced by refining your piloting techniques (don’t ascend/descend too fast, etc…). However, the default configuration isn’t ideal for video capture. Though, much of that can be corrected with some ad-ons (which I will be investing in), and software-based video stabilization in After Effects. Again, I’ll cover this more in a bit…

Lessons Learned

My explorations into aerial photography have provided me with some valuable lessons…

  • Accept the fact that you will crash.  Even though the Phantom is very easy to fly, at some point you will, without a doubt, crash the copter. Luckily every piece of the copter can be replaced. If your battery is almost dead and you try to take off, the copter will just flip over onto the ground. If you are trying to land and there is a strong gust of wind, you will likely crash. If you descend too quickly, you will crash. I mention each of these, because I have done all of them.
  • Immediately replace the nuts that hold the propellers onto the copter.  Within the first week of owning the Phantom, I lost a propeller and the copter came plummeting to the ground. Luckily, I was only about ten feet off of the ground when this happened. The “dome” nuts that ship with the copter look pretty, but are not reliable. Get some new nuts with lock washers, Nylock nuts, and/or some thread lock to prevent the nuts from loosening due to vibration. If you use thread lock, just be sure NOT to get any on the plastic propellers. I have heard it will do bad things to them.
  • Be prepared to obsess over the ways that you can use and modify the copter. This leads me to my next section…

Add-Ons

If you are like me, you will immediately want to explore all of the ways that you can use the Phantom once you get it. This will lead you down the road of watching countless YouTube videos that others have created, reading DIY instructions for modifications, and scouring the web for upgrade options.

Must haves:

  • Extra batteries. The Phantom comes with one battery that lasts 10-12 minutes. You will want more batteries for additional flight time.
  • Better nuts to secure the propellers. (See my lessons learned above)

Of course, not all modifications are “must haves”; here are the next few options that are on my list. If anyone is looking for a gift idea for me, look at this list! :)

  • Travel Case. Without a doubt, you will want to protect your copter. I have mine in a cardboard box lined with bubble-wrap to prevent damage from travel and toddlers. If you plan on travelling with your copter (which I do), you will want something like one of these.
  • Upgraded Propellers. Larger propellers provide additional lift. Balanced propellers provide less vibration. Stiffer propellers also provide additional lift. The Phantom ships with 8″ plastic props. I’m looking into 9″ wooden or carbon fiber, balanced propellers.
  • Camera Gimbal System. A gimbal system will keep your camera stable, regardless of the pitch or yaw of the copter. This will make a huge difference if you are producing video. There are lots of options, from DIY kits, to the official DJI/Zenmuse Gimbal system that was just released today. I am drooling over these options.
  • Vibration Isolation Mount. If you have a gimbal, you probably already have this, but if you don’t, you might want one. A vibration isolation mount will reduce the copter vibrations that are transferred to the camera. This will result in better quality images and videos, and less “jello effect”.
  • ND/Polarized filters for the GoPro camera. ND filters and polarized filters can help improve the captured image or video, and can minimize the “jello effect” due to vibrations.
  • FPV Video Navigation System. An FPV (First Person View) video system gives you the ability to see exactly what the copter sees when you are flying. This can be really useful for framing of photos, or flying beyond line-of-sight. Most of these will require you to modify your copter. You can use the GoPro app as a limited FPV system; although keep in mind that it operates over an ad hoc wifi connection. If you lose the connection, you lose the video feed.

I mentioned that people are creating amazing images and videos with this rig; here are just a few that blew me away…

… and there are many, many more.

Creative Cloud

So, I’ve written all about the copter so far, but what about Creative Cloud?  How does it tie into quadcopters? Creative Cloud enables you to do more with the aerial imagery that you capture from the quadcopter.

When taking still images, I setup the camera so that it will automatically take two pictures every second. When you’re flying for 10 minutes, this ends up being a lot of images. Lightroom enables you to quickly import, tag, develop, and publish your images.

Many of the images need additional editing before they are suitable for your final product. Whether you need to remove objects (such as landing gear, shadows, people, etc…), or you want to tweak clouds or make other dramatic changes, Photoshop enables you to do these things. Photoshop enables rich editing and retouching of images.

Advanced Editing in Photoshop CC

Of course, it’s not all about still images. Premiere and After Effects enable editing and production of your captured videos. You can use Premiere to arrange multiple clips into a broader sequence, and you can add post-processing effects and image stabilization with After Effects.

…and what is a video without audio? Audition provides you with a rich environment for audio production. Whether it is editing the captured audio, or producing new music and soundtracks, Audition has you covered.

Here’s another video that I produced using Premiere for edits, stabilization with After Effects, and Audition for audio tweaks. Granted, I do not have a gimbal or other stabilization system, so bear with the quality!

This is just the proverbial “tip of the iceberg”. Creative Cloud gives you the tools you need to create amazing multimedia content, and the means to make that content engaging and interactive – from hobbyist to die-hard professional.

Once you’re happy with what you’ve got, don’t forget you can share it on Behance via your Creative Cloud membership!
