About this project
After years experiencing the limitations with current video stabilization technologies we decided to take a drastically new approach to developing our own solution.
Using SteadXP's built in accelerometer and gyroscope, your camera's movements are accurately recorded as you shoot. When you're finished, just connect SteadXP to your computer and watch as the software stabilizes and reduces all of the unwanted artifacts in the footage.
And beyond stabilization, our advanced software features turn any of your handheld shot in a perfect cinematic move:
The real breakthrough is how free you are to film without the hassle of any mechanical structure between you and the camera. Now you can do crazy camera movements and decide only later how smooth your shot is going to be.
Just plug your SteadXP on your camera, and you are immediately ready to start shooting.
In practice, your camera records unstabilized video as usual. In the same time our device saves all camera movements.
Then our post-treatment software will automatically upload, extract and process datas to compensate for any unintentional movements.
Within a few seconds, SteadXP software will suggest you to choose between different trajectories already optimized for your shot, resulting in different typical looks.
Pick one profile, quick preview, click Run and that's it!
Under the hood, our algorithm automatically builds a new virtual camera trajectory freed from geometrical distortions, vibrations and even the worst rolling shutter deformations.
So it is now possible to film handheld, without gimbals, glidecam, steadycam or shoulder rig.
But of course SteadXP shouldn't be seen as a strict competitor to traditional stabilization solutions. Our device will also bring an added value (Horizon lock, reframing...) in association with your mechanical stabilization system.
A major advantage of SteadXP technology compared to 100% software solutions is how fast and robust is the processing. Knowing everything about your camera movement, we don't need to run a "first pass" analysis on your video.
Computation time is therefore very significantly reduced. Moreover, if you ask us the GPU support, we will add a Stretch Goal during the campaign. You can therefore expect real time correction even in a 4K workflow!
By it's unique workflow, SteadXP opens new filming opportunities to both the professional filmmakers looking for the perfect framing, and to athletes filming with POV mounted cameras.
We developed 2 versions of SteadXP. SteadXP@ is made specifically for GoPro®* cameras, and SteadXP+ is designed to fit almost any other video camera.
To make no compromise on stabilization quality, both SteadXP models share key components:
- powerfull 32 bit ARM processor,
- 3 axis gyroscope,
- 3 axis accelerometer,
- microSD card slot (FAT16 / FAT32 class 4 min: 32 GB max),
- USB connectivity (Mass Storage Device)
SteadXP@ is a 34 grams accessory you just plug on the expansion port of your GoPro®* camera, and that's it ! Powered by the host camera battery, you can start and stop your recording as usual, in any of the video modes (wide modes are recommended for the most dynamic scenes).
SteadXP@ fits inside the GoPro®* waterproof case with its extension backdoor**.
SteadXP+ is a 60 grams accessory compatible with nearly all pro and semi-pro cameras. It only requires:
- an accessible flash mount (standard coldshoe),
- a stereo microphone input,
- and a video output (AV Out).
You can also use SteadXP+ on professional cinema cameras, with several options how to ensure the synchronization (standard Genlock signals: bi or tri-level sync).
SteadXP HMDI: [UPDATE: #4 Stretch Goal UNLOCKED] Same characteristics than SteadXP+, but compatible with your HDMI Out!
The standalone SteadXP software allows to:
- preview stabilization results,
- cut several sequences,
- and adjust rendering options if you are looking for a particular result.
From day one, we are looking for the most intuitive user experience. Our software combines 2 different approaches: Set and Run features (1 clic approach), or intuitive advanced tuning functions with Semi-automatic features.
Several stabilization profiles are proposed by the software: covering different typical kind of shots (various action sports, horizon lock, hyperlapse, handheld footage, shoulder rig shot, virtual tripod etc...). Picking the appropriate profile (or following software recommendation) gives great results most of the time.
You can always create new profiles or quickly adjust rendering options based on several parameters (stabilization intensity, desired crop factor, Hyperlapse speed, enable Horizon Lock / Virtual Motion Blur / Pixel interpolation functions etc...) to produce the exact result you were looking for.
Some camera movements like quick panning shots are particularly unpleasant to watch without motion blur effect. By enabling this option, SteadXP software will add a virtual motion blur, for which you can set effect dynamic and intensity.
Video example : without / with Motion blur option (alpha version : work in progress)
Sometimes, the rotation amplitude of a handheld camera can be so large that even a very wide-angle lens is not enough to produce a very smooth trajectory, especially when the Horizon Lock option is enabled. The time of one missed step, a sudden rapid move can ruin your shot by unfortunately affecting a few frames.
If you set custom options trying to fix this high amplitude rotation with high smoothing level, a black zone can briefly appear in the output corners of the frame, due to the lack of input pixels!
To avoid that, our algorithm uses past and future frames to fill this black zones. It automatically reconstructs missing parts of the frame without any noticeable defect. This is a useful function when stabilizing the most dynamic scenes.
Video example : without / with pixel interpolation option
Beyond automatic features, if you are looking for a particular rendering effect, you can take total control of framing with a complete set of semi-automatic features.
By a few manual interventions, and with the help of the preview window, drive intuitively your final virtual camera trajectory.
If you are in quest for the perfect framing of your scene, our interactive timeline will give you a complete control on final result. You can intuitively add and edit orientation keyframes to match the exact framing you were looking for.
Reframe your subject in post with SteadXP software
Attaining the stretch goal #3 will allow us to implement automatic following of subjects on screen. Face detection will help you identify the subject to highlight, follow, and to maintain in a particular zone of the frame.
One of our future plan for SteadXP is to release Mobile Applications (Android, iOS) to complete the workflow with a quick preview solution to validate the shot on the spot, at least in low resolution.
For the highest resolutions rendering (like 4K), you will still need the desktop application, but it will be a very convenient addition to support a demanding professional workflow.
As you can see below this custom Stretch Goal is one of those we propose to build in a collaborative mode. Feel free to join the discussion!
Of course this is still a work in progress demo (and one of this custom Stretch Goal we propose to build together), but you should take a look at what we have accomplished so far with only 2 GoPro®*!
SteadXP is the first device to automatically keep horizon stable when filming Virtual Reality immersive shots...
Adding this to SteadXP's native rolling shutter correction technology, means you'll never be sick again in watching VR videos!
Of course, what has been done with 2 cameras can become a reality with 4 or 6, and with any existing multi-cameras rig using SteadXP@ or SteadXP+... Just spread the word if you are interested in this feature, and we will build a new Stretch Goal for this!
Whatever the model of camera you use (genlocked pro camera, GoPro®*), at this date you can't use traditional gimbals, OIS and EIS stabilization systems in 3D shooting, that's a fact.
So SteadXP is therefore the first technology to stabilize your 3D shots!
Thanks to you backers, we unlocked Stretch Goal #2! So now, you can back the SteadXP from Europe, USA, Canada, Japan, South Korea, Australia, China, Taïwan, Hong-Kong, Singapore and Russia.
And of course we will ship worldwide after another Stretch Goal to come if you make us a very successful project!

First SteadXP independent review
Why we need your help
The development of SteadXP started 3 years ago and our hardware and firmware are mature. All technological barriers are crossed, all critical components are sourced and boards are nearly ready for production.
But at this date, our software requires a dose of polish! All functions are implemented and stable, but we need to hear your feedback to reach the best user experience possible.
Of course we need your contributions to hire developers, pay contractors, run quality and robustness testing, logistics, tooling and certification of the boards.
But most of all, we need every each of you as an ambassador for our products. Because SteadXP technology is what we call an unexpressed need: if people don't hear about us, we know they are not looking for a technology like SteadXP. Just because there is no equivalent solution!
A Kickstarter campaign will certainly help us spread the word, but it will work ONLY with your personal involvement! SteadXP is by far the best stabilizing and cinematic shot solution in its price range, let other people know about it!
Moreover, the more funds we collect, the faster will be the delivery of your rewards, and more cool features will be added. So please share the news with your community; you can write about it on forums, or tweet it to your favorite Tech blogger... Beat the drums about us, we need you!
Risks and challenges
We have been working hard on improving SteadXP, and today all critical components are sourced and tested with a stable firmware ready for production.
Research is far past, development is nearly finished, and we are confident in our capacity to ship products in their respective deadlines.
However, there is always the possibility that problems may arise and affect reward delivery.
While we anticipated EMI certification of the boards, an initial rebuttal is always possible. This could delay the project by a few weeks.
We may face unexpected delays from our suppliers, and this could delay the production and shipping for several weeks.
All videos on this webpage were made exclusively with SteadXP software, and we hope you are impressed with the results.
However, much work needs to be done before releasing it to all platforms.
The SteadXP software is currently an alpha version allowing us to validate our algorithms and compare different user experiences in a coherent workflow.
While we hope adding new features to the SteadXP software thanks to your feedback, our top priority is to deliver SteadXP according to the schedule, even if this means releasing updates later on.
Of course we promise to keep you updated and informed on the production advancement and reward delivery progress.Learn about accountability on Kickstarter
Final retail prices will be 250€ for SteadXP@ and 380€ for SteadXP+.
SteadXP@ is compatible with GoPro®* H2, H3 White / Silver / Black, H3+, H4 Silver / Black. H4 Session is not supported, and about H5 who knows ?
SteadXP+ will be compatible with any camera able to simultaneously accomplish the following points:
- internal recording of the video,
- recording of an external stereo audio signal,
- AV-OUT or HDMI OUT (1080 max) : outputting video signal while video recording.
You will need a standard coldshoe to mount the SteadXP too.
So it means nearly all cameras on the market, but please carefully read and check this points in each of the video mode you plan to use with the SteadXP+. Because we can't get and test every camera!
To summarize, if you can plug an external STEREO microphone on Mic IN of your camera, record a video and simultaneously see a valid video output via AV-OUT or HDMI : it's ok!
Note that with our SteadXP+ prototype, using HDMI output, Genlock Out or Genlock IN, you’ll need an adequate adapter (BNC to RCA) or converter (HDMI to AV).
Also, SteadXP+ works only if all internal image stabilization (OIS / EIS) is disabled on the camera.
Please contact firstname.lastname@example.org we will do our best to find a solution, and could refund your pledge if no solution is found!
Yes, but only if you lock the focal to one of its extremum position.
SteadXP+ uses the audio on your camera for the initial synchronization of each recording. In order to record a video with sound, you can either unplug the SteadXP+ audio cable from the camera about 2 seconds after you start the recording, or you can use an external audio recorder.
It is not recommended to use SteadXP+ in this configuration, but it will be possible by an added procedure. You will need to do a typical movement with your camera connected to a recording camera / SteadXP+ (like a 180° rotation on roll axis).
This particular move will automatically be detected by our algorithm, helping you to sync SteadXP datas to your videos in a semi-automatic mode.
But of course it's a lot easier to use our sync audio signal!
Our desktop application will be compatible Win32, Win64 and Mac OS X, with at least 2GB of available RAM and 10GB of free disk space.
