Filming any video content on a device that isn’t mounted on a tripod is going to end up with some level of video shake; it’s just an inevitable fact of life. It could be so slight that it’s hard to detect, or could perhaps be so severe that you might believe the camera operator was trapped inside a washing machine. We’re going to take a look at why video shake happens and how it can be effectively tackled.
Video shake appears in footage when the device being used to capture the video changes its position. This effect becomes more pronounced under certain conditions, such as low light and recording at 4k resolution when the well known 'Jello' effect that can be encountered. The more you crop into an image in post-production video editing the more noticeable the shake will become too.
The most common sources of shaky videos come from mobile phones and action/adventure themed cameras such as the famous GoPro series. Both modern smartphones and GoPro Hero cameras will have some level of automatic image stabilisation which works by the displayed image being a cropped in version of what the camera’s sensor is actually recording. This allows the camera’s software to automatically move this crop around the wider image, based on the movement of the camera, compensating for movement and reducing image shake.
Low light is often an issue for screen shake as the less light hitting the sensor of the camera, the longer the shutter must stay open for to allow enough light in to make the image usable. This means each frame will have more blurring around the outside of the image as the image is created over a longer period of time, and so movement of the camera while the image is being formed will be more noticeable.
What are the solutions for video shake?
There are several steps you can take to reduce the amount of video shake, but the majority of these take place before you take your footage.
Using a gimbal is a fantastic way to help keep an image steady, particularly If you’re doing something active that would result in an unsteady camera anyway. However, as good as they are, you’ll only really know how usable your footage is when you watch it afterwards.
In-built image stabilisation will also help out a whole lot and you can enable this in a camera’s options but sometimes it still won’t be enough.
Fixing shaky footage in post-production is possible in Adobe Premiere-Pro, but it is expensive software that can be difficult to navigate around and is going to be overkill for the average user, not to mention the resource strain it can put on slower machines.
Digiarty’s VideoProc provides a ‘deshake’ option within its toolbox that can be applied to footage in post-production.
A wide array of options is available to ensure you’re getting the best results from this option too. The embedded Full Hardware Acceleration Tech helps VideoProc to make the best use of your hardware too, to ensure you’re getting excellent results in the fastest possible time.

Why is VideoProc the best solution for video shake?
VideoProc combines the benefit of being extremely powerful software while remaining light-weight and easy to use.
Several video editing programs will struggle when it comes to handling 4k footage because of the amount of raw data involved, but VideoProc supports full hardware acceleration allowing it to make full use of your computer's resources when it tackles these larger tasks. This will not only mean more consistent results for your video editing projects, but will also significantly cut down on rendering and processing time too.
VideoProc contains a wide range of tools for all your video production needs too, all easily accessible and clearly laid out, making it the best choice for people who want a powerful but simple to use video editing tool.
Digiarty is the maker of VideoProc and also produce WinX DVD Ripper which allows you to rip DVDs in just a few clicks.
