Is GoPro HyperSmooth Actually Perfect for 4K Video

HyperSmooth is a kind of Electronic Image Stabilization (aka. EIS), aiming to give your GoPro video recordings gimbal-like stabilization but without the gimbal. It is conducted by cropping in slightly on the picture and warping the edges to compensate for the shakiness.
HyperSmooth can be used for many resolutions and frame rates, including several 4K video modes, namely, 4K 60/50fps, 4K 30/25fps, and 4K 24fps. How is HyperSmooth doing in 4K videos? Is it really perfect for 4K videos? Do we still need gimbal or post-processing to stabilize GoPro 4K video?
Why GoPro HyperSmooth Is Not Perfect
Well, after watching many HyperSmooth-assisted videos, We'd admit that HyperSmooth does make a big difference. The videos with HyperSmooth are less shaky than those without HyperSmooth. However, nothing is perfect. Here are the most discussed issues:
1. HyperSmooth isn't available for 4K 60fps in Hero 7 and earlier products.
Some users report online that their GoPro HERO7 Black doesn't have HyperSmooth for 4K 60fps. As we mentioned in the second paragraph, HyperSmooth can be enabled while recording 4K 60fps videos. However, the aspect ratio format must be 16:9. If you're in a 4:3 format, change it to 16:9. If HyperSmooth is still not available, you probably haven't done the firmware 1.51 update. Now update it following the steps below:
Open the GoPro update page and choose HERO7 Black.
Under "OTHER WAYS TO UPDATE", choose "Update your camera manually".
Enter your 14-Digit Serial Number and other requested information, click "Next Step".
Click "Download Update."
Click "Click here to download firmware."
Follow the steps on the screen for detailed instructions for your operating system.
2. HyperSmooth causes issues in videos during slow panning.
If you do slow panning left-right or up-down with HyperSmooth on, you will see noticeable rubber banding, stutter, or freeze. This issue has displeased many users, and worse still, there's currently no way to fix it except for disabling HyperSmooth. This is because HyperSmooth is built for creating more smooth video captures as the camera moves along, as opposed to slow panning. Perhaps, this can be fixed by further firmware updates.
3. HyperSmooth doesn't work well in low light.
Have you noticed that the video is still very shaky at night or in low light conditions, although you have turned on HyperSmooth and you have applied the best settings? You will figure out the reason after you know how EIS works.
EIS needs a lot of information in the original picture to be able to stabilize the video well. When you shoot in low light, there will be limited information that EIS can use to stabilize your capture. That's why HyperSmooth cannot stabilize video well in low-light situations. To improve the EIS performance in low light, you can increase the shutter speed and raise the ISO. But the drawback is that it will add noise to your video.
4. HyperSmooth also drains the battery quickly.
HyperSmooth will consume a bit of battery. According to some users' feedbacks, the battery doesn't usually last more than an hour when shooting videos in 4K 60fps mode with HyperSmooth. When HyperSmooth is disabled, the GoPro HERO7 Black can work longer.
5. HyperSmooth crops away a lot of frame area.
While stabilizing video, it will crop off 10% to 20%. As a result, the FOV will be too narrow.
Is Gimbal or Post-Processing Still Necessary to Stabilize 4K Videos
Different people have different ideas. Some people think GoPro HERO lineup's HyperSmooth can replace Gimbal. They think that the results are impressive under normal use, and can also be great in certain situations if they try hard enough.
However, others believe that gimbal cannot be replaced. This is because there are still times when only Gimbal can work efficiently, after all, HyperSmooth isn't as perfect as GoPro advertises.
And there is still a need to do stabilization in post-process, if HyperSmooth doesn't work well in some situations and if you don't have a gimbal. Adobe Premiere Pro, iMovie, and GoPro Quik are often used to stabilize shaky footage in post-editing.
How to Stabilize GoPro Video in Post-Processing
The stabilization feature vary from software to software, some offers detailed and advanced options, while some just give you an enabling button. But essentially, they are woking on the same basics. Genrally, there are mainly four parameters to adjust in the post to stabilize videos:
Shakiness - sets how shaky and quick the camera is.
Accuracy - sets the accuracy of the detection process.
Step Size - sets the range of searching identified macroblocks in the process.
Minumum contrast - sets the contrast between the shakiness and the stillness.
