RockSteady vs HyperSmooth, Which One Is Better?

By Farrah Penn Updated: May 24, 2019

When DJI announced its rugged camera Osmo Action on May 15th, the world saw a competitive player in the pool of action camera, which is previously dominated by GoPro. Among other specs, such as the unique dual display and 11-meter waterproof, you might also be curious about RockSteady stabilization, DJI Osmo Action's Electronic Image Stabilization (EIS) algorithm. After all, stabilization is essential for action camera in reducing jittering and blur when you are running, mountain biking and recording all the other breath taking moments of extreme sports. Read on if you are interested in RockSteady vs HyperSmooth regarding their stabilization abilities.

Here is a RockSteady Resolution list for you to check which resolutions use RockSteady.

Resolution FPS Stabilization
4K (3840x2160) 60, 50, 48, 30, 25, 24 RockSteady
2.7K (2720x1530) 60, 50, 48, 30, 25, 24 RockSteady
1080p (1920x1080) 240, 200, 120, 100 unavailable
1080p (1920x1080) 60, 50, 48, 30, 25, 24 RockSteady
720p (1280x720) 240, 200 unavailable
4K 4:3 (4000x3000) 30, 25, 24 unavailable
2.7K 4:3 (2720x2040) 30, 25, 24 RockSteady
HDR 4K, HDR 2.7K, HDR 1080p 30, 25, 24 unavailable

RockSteady vs HyperSmooth: which one does a better job?

We run a test on DJI Osmo Action and GoPro Hero 7 Black to compare their stabilization performance. For most users, EIS in DJI Osmo Action and GoPro Hero7 Black deliver similar performance in most cases, at least to the bare eye. While some users claim that DJI's RockSteady produce better footage than GoPro in the most extreme scenarios, when significant bumps occur.

Here are RockSteady vs HyperSmooth quick facts:

● HyperSmooth was firstly introduced in GoPro Hero7 Black.

● RockSteady made its debut in DJI Osmo Action Camera.

● Both system utilize Electronic Image Stabilization (EIS) algorithm.

Cropping is inevitable in EIS, as cropping is at the core of the algorithm to cut image edges and offset skewed image.

● GoPro claims to crop videos by 10% (5% on each side); DJI also crops 10%.

● RockSteady doesn't support HDR video or Slow motion.

● HyperSmooth doesn't support video looping.

For general video recording mode, EIS availability on DJI Osmo Action and GoPro Hero 7 Black differs in resolution and frame rate, though they both support up to 4K@60FPS. RockSteady doesn't support HDR video, and Hero 7 Black doesn't have HDR video at all. Video Looping is available on GoPro, but stabilization cannot be enabled.

To be clearer about video modes and stabilization options, i.e. which resolutions use RockSteady, or HyperSmooth (and Standard Stabilization, a pre-Hypersmooth algorithm on GoPro), check out below RockSteady vs HyperSmooth Resolution list.

*Note 1: The resolutions of 2.7K, 4K 4:3 and 2.7K 4:3 on DJI Osmo Action and GoPro Hero 7 Black is slightly different in pixels.
For Osmo Action, it is 4K 4:3 (4000x3000), 2.7K 4:3 (2720x2040), and 2.7K (2720x1530);
while for Hero7 Black, it is 4K 4:3 (4096x3072), 2.7K 4:3 (2704x2028), 2.7K (2704x1520).

**Note 2: The divergence between NTSC and PAL dates back to the era of analogue television. Since the signal is related to the frequency of electrical power in a certain region, and the fact that NTSC region uses 60Hz while 50Hz is the norm in PAL region, a wrong set will cause incompatible issues across regions. NTSC is commonly used in North America, Some region in South America and Japan; while PAL is common in European, Australia, and parts of Asia.

FAQ: RockSteady vs GoPro HyperSmooth

How to enable RockSteady in DJI Osmo Action (I only see EIS logo)?

RockSteady is automatically enabled when you choose the capable Resolution and FPS combinations. You will see the blue "RockSteady" mark in the Resolution/Frame rate settings. If you see "EIS" instead, just update the firmware of DJI Osmo Action.

How to update the DJI Osmo Action Firmware to enable RockSteady?

With DJI Mimo App

Step 1. Download DJI Mimo App on your mobile.

Step 2. Tap at the camera icon in Mimo to connect with your Osmo Action, select your device and make sure the verification code is identical.

Step 3. You will see "New firmware available. Return to home to update." Click home icon, and download the firmware. Osmo Action will finish the update process automatically.

With Micro SD card

Step 1. Download the latest Osmo Action Firmware from DJI's official site.

Step 2. Copy it to the root directory of a microSD card.

Step 3. Insert the miscroSD card into Osmo Action, and power on the camera. It will automatically update when the file is detected. You just wait until it’s done.

How to turn off RockSteady / Hypersmooth?

Just tap at the RockSteady logo to turn it off on DJI camera. To turn off Hypersmooth in GoPro, tap at video settings to toggle off.

Can I use RockSteady / Hypersmooth in HDR videos?

No. Osmo Action allows you to film High Dynamic Range videos, but RockSteady doesn't support HDR mode. GoPro Hero 7 doesn’t support HDR videos at all.

Hypersmooth is not enabled in certain FOV, how about RockSteady?

DJI Osmo Action doesn't offer a manual switch between the viewing angles, comparing to GoPro's linear, wide, super wide options. In this regard, you might be slightly disappointed if you want a wider view in certain scenarios to include more details. You can use below chart as a guide to see which resolutions, FPS and FOV supports HyperSmooth and Standard Stabilization on GoPro Hero7 Black and GoPro Hero6 Black.

Have strange effects in low light when stabilization is enabled?

GoPro: EIS is not enabled in low light scenarios on GoPro Hero6/5. Though HyperSmooth (first introduced in Hero 7 Black) can be enabled in low light, it used to cause strange effects. To deal with these strange effects inevitably caused by EIS in low light, GoPro release an update of firmware v1.61 on Dec 11, 2018. With this update, HyperSmooth will now dynamically change the level of stabilization with regard to different light conditions at night.

DJI: RockSteady can be set on in low light scenarios. However, DJI doesn't give any information on whether RockSteady adopts dynamic change in the level of stabilization for now.

Is stabilization to be blamed for image flickering in low light?

For low light scenarios, especially when you are shooting at night under fluorescent lamp, you might notice a flickering in the image. That's not one of those strange effects caused by enabling EIS, but due to wrong FPS settings. You have either wrongly chosen the NTSC set of 240,120,60,30,24 fps when you are in PAL region, or PAL set of 200,100,50,25,24 fps when you live in NTSC region.

Final Words

RockSteady on DJI Osmo action and Hypersmooth on GoPro Hero 7 Black both produce well-stabilized videos. The difference lies in stabilization availability on certain resolution and FPS combinations, though both RockSteady and HyperSmooth support up to 4K 60FPS. Besides In-camera stabilization, you can also rely on EIS in post editing to fix shaky videos, which supports a wider range of video types such as HDR videos, and resolution & FPS combinations. Above all, most DJI focused video editing tools are programmed with stabilizers with advanced algorithm to enhance your footage, alongside with other handy functions to cut, trim, crop and convert videos.
