Electronic vs Optical Video Stabilization: Which Is Better?

Three types of stabilization, one goal

Video stabilization falls into two families: optical and electronic. Optical stabilization happens before light reaches the sensor, by moving either the lens elements or the sensor itself. Electronic stabilization happens after capture, when the camera reprocesses the image to remove shake.

Optical stabilization in a lens, sometimes labeled OIS or VR, uses floating lens elements that shift to counter camera movement. In-body stabilization (IBIS) moves the sensor on a gimbal-like mechanism. Both are optical because they physically redirect light before it is recorded.

Electronic stabilization, sometimes called digital or EIS, uses the camera's processor to analyze each frame and shift the image digitally. Because it needs room to maneuver, the camera typically crops into the sensor area. The tradeoff is a narrower angle of view. Understand that tradeoff before you buy. The image stabilization guide explains the basics of each type in more detail.

A camera that combines in-body and lens stabilization is often called dual IS or sync IS. The body and lens communicate, and each corrects for different types of movement. This is the most effective optical approach for handheld video.

How electronic stabilization works

Electronic stabilization works by comparing consecutive frames and shifting the image to keep the subject steady. The camera needs a margin of unused sensor area to move into, so it crops the frame. A 4K video that uses the full sensor width may become a narrower crop when electronic stabilization is enabled.

The crop also means the camera uses only part of the sensor's pixel area. That is fine for video resolution, since 4K is typically only 8 to 12 megapixels even on a high-resolution sensor. But it can affect your lens choice: a wide-angle lens becomes less wide when the crop is applied.

Electronic stabilization is most common in compact cameras, action cameras, and smartphones, where there is little room for moving parts. It can also be combined with optical stabilization in a hybrid system: the optical part handles low-frequency shake and the electronic part handles residual movement.

Some cameras apply electronic stabilization only when shooting in a cropped video mode, and others allow it on the full width. Check the spec page for the specific camera you are considering. The 4K video explained guide covers how crop factors affect 4K capture.

Optical stabilization in lenses

Lens-based optical stabilization is the longest-established method. It is especially effective at telephoto focal lengths, where small camera movements produce large image shifts. Many telephoto zoom lenses used for wildlife video rely on it.

A lens with optical stabilization has its own correction limits. The CIPA standard (DC-011) defines a measurement method for lens stabilization performance, which is often published as a number of stops. That number tells you how much slower a shutter speed you can use compared to no stabilization, but for video the benefit is smoother footage, not just sharper frames.

The drawback of lens stabilization is that it only works with that specific lens. If you switch to a lens without stabilization, you lose the benefit. In-body stabilization works with any lens, which is why many hybrid shooters prefer a body with IBIS. The lens vs IBIS stabilization article examines the tradeoffs in detail.

When choosing a stabilized lens for video, remember that the stabilization rating on the spec sheet is measured for still photography. Video stabilization is judged subjectively by how smooth the footage looks. If you shoot mostly video, look for lenses and bodies that are known for their video stabilization behavior, not just their CIPA rating.

In-body stabilization for video

In-body stabilization (IBIS) moves the sensor to counter camera movement. For stills it is measured in stops of shutter speed improvement. For video it provides a floating, gimbal-like feel that is especially useful when walking or panning.

IBIS is common in full-frame, APS-C, and Micro Four Thirds mirrorless cameras. The Micro Four Thirds standard, defined by an open standard group, includes a strong tradition of in-body stabilization. The group's website describes the system's goals of compactness and lightweight with high image quality. A compact body with IBIS is a practical choice for travel video.

Because IBIS moves the sensor, it can also affect the image circle. At the edge of the frame, the sensor may move beyond the lens's image circle, which can cause corner softness or vignetting. This is more common with very large sensor movements at wide angles.

For handheld video, IBIS is generally more useful than lens stabilization because it works with any lens, including primes and adapted lenses. It also helps with stills, giving you a stabilization solution even when you use a lens that lacks optical stabilization. These best mirrorless cameras with 4K video have strong IBIS systems for handheld shooting.

The crop problem with electronic stabilization

The main downside of electronic stabilization is that it crops the image. Some cameras allow you to combine electronic stabilization with an already-cropped 4K mode, which can result in a significant loss of angle of view.

For example, a camera that shoots 4K from a Super 35 or APS-C crop might already have a 1.5x crop factor compared to full-frame. Adding electronic stabilization on top can increase that to nearly 2x. A 24mm full-frame lens may end up looking like a 48mm lens, which is a major change for indoor video.

The crop also makes it harder to shoot with a specific composition in mind. You frame the shot through the viewfinder or on the LCD, but the recorded video shows less than what you saw. Some cameras show a frame guide for the stabilized area, but not all do.

If you are choosing between a camera with good optical stabilization and one that relies mainly on electronic stabilization, consider what you shoot. For vlogging, run-and-gun documentary, or travel video, the wider angle of view from optical stabilization is worth the price. See the best video cameras guide for models that balance stabilization with other video features.

What to pick for your use

For most video work, a camera with in-body optical stabilization is the best starting point. It keeps the lens options open and provides a stable base for handheld shooting. Add a lens with its own optical stabilization for a dual system that handles most focal lengths.

If you shoot with an action camera or a compact camera, electronic stabilization is often the only option. Modern action cameras have impressive electronic stabilization that smooths out high-frequency shake. Just be aware of the crop and the potential loss of wide-angle coverage.

No stabilization system replaces good technique. A light tripod, a monopod, or a gimbal gives the steadiest results. For static shots, a tripod is still the best option. The tripod mount and stabilization article covers these accessories in more detail.

Finally, understand that stabilization interacts with other video settings. A camera that crops into the sensor for 4K may behave differently with stabilization on. Compare the specs of the best 4K cameras and best compact cameras with 4K video to see which models give you the angle of view you need.

Questions

Which is better for video: optical or electronic stabilization?

Optical stabilization is generally better because it preserves the full field of view and avoids the crop that electronic stabilization requires. It also corrects movement before the sensor records, so there is no processing penalty.

Does electronic stabilization reduce video quality?

It can. Because the camera crops into the sensor, you record a smaller area, which can lower the effective resolution or narrow the angle of view. Modern implementations are good, but the crop is a real tradeoff.

Can you use both optical and electronic stabilization together?

Yes. Many cameras offer a hybrid mode where the optical system handles low-frequency movement and the electronic system handles residual shake. This gives the best result but still applies a crop.

How much does electronic stabilization crop the frame?

It varies by camera. The crop is usually around 1.1x to 1.5x, but when combined with a 4K crop mode it can be more. Check the spec page or the camera menu for details on the effective angle of view.

Is in-body stabilization as good as lens stabilization for video?

For wide-angle and standard lenses, IBIS is often more useful because it works with any lens. For telephoto lenses, lens stabilization is more effective because it corrects the larger image shift at long focal lengths. A combination of both is best.
