Video stabilization is one of the most crucial tasks in post-processing video files. Often, shooting conditions do not allow for achieving a perfectly stable image, especially when shooting with a phone without a tripod. However, even using a tripod in cinematography does not always guarantee the effect of a stable and steady image, free from the "jelly effect" and stationary objects shaking.
Professional video editors know that conducting high-quality video stabilization is a meticulous job that requires effort, time, and specific skills. Beginners typically make basic mistakes that lead to various issues with stabilization.
Video stabilizer — why do you need video stabilization?
Video stabilization online may be needed for several reasons:
- Insufficient stabilization during shooting: lack of a tripod or its instability, shaky hands, or shooting while in motion.
- The use of filters can also create a jelly effect.
- Technical equipment issues: malfunctions in the lens or camera sensor, or other technical glitches.
So, your video quality is not satisfactory. What steps can be taken?
How to stabilize a shaky video?
The main goal of stabilization is to make the image stable. Video stabilization software involves analyzing motion and anchoring it to a single point. For smooth footage, we need to stabilize not the entire frame, not the person or object in the frame, but static surfaces. For example, if there's a person in the frame against a wall, we need to stabilize the wall. However, if the person is walking, we want them not to lose movement. To achieve stabilization, the video editor analyzes the image and determines what should move, what should remain still, or what should keep moving smoothly.
What methods of video stabilization are there?
There are automatic methods of video stabilizer for phones where the program analyzes the image and, according to its algorithm, attempts to stabilize it. These algorithms analyze a large object and make efforts to stabilize it. However, the result may need improvement. Some motion that was supposed to occur may also be stabilized, leading to the "jelly effect" in the frame, distortion of the entire image, and additional planes starting to move in space.
The main task of a video editor who creates a good, stable image is to determine which object needs to be stabilized. This comes with its own set of challenges. If the video was shot with a tripod but experienced some shaking, it's one task because we know which object is not moving. If the video was shot handheld and there is movement in both the person being filmed, the background, and the camera, it involves triple motion. In this case, it is necessary to determine the relationship between the background, the subject being filmed, and the foreground so that they are coordinated relative to each other.
What are the main video stabilization tools?
There are two main video stabilization tools often used by professional video editors:
- Point tracking: This is a simpler method. In this approach, the editor identifies a point in which he is confident that it will be the most stable one. They then attempt to calculate and track its movements throughout the entire frame. Another point that is in motion is then assigned, and all coordinates of its changes relative to the stable point should be compensated by changes to the entire frame. In other words, the frame itself moves so that the stationary point remains stable. This results in a stable image where one of the objects designated by the video editor becomes static.
- Volumetric tracking: In this method, 2-4-8 points, or an entire surface in 3d space, and their dependencies on each other are determined. If there is panoramic movement, the video editor finds the changing relationship between these points and stabilizes them to avoid the "jelly effect." It is a complex volumetric work that involves analyzing each point and the relationships between points. Only through such an approach can one achieve a maximally high-quality result.
