Every modern camera promises smooth video. The promises mean very different things, and only some of them survive a walk down a real street.

"Stabilisation" on a camera spec sheet is a single word covering four very different technologies. Each one solves a different problem, each one introduces its own trade-offs, and only some of them combine well. Once you know what each system actually does, the right choice for a given shoot becomes obvious instead of guesswork.
A floating optical element inside the lens shifts to counteract small movements detected by gyros. OIS is excellent at correcting hand-tremor and small high-frequency vibrations. It does almost nothing for the big "walking bobbing" motion of someone striding forward — that motion is too large and too low-frequency for an optical element to follow.
The entire sensor sits on a movable platform and floats inside the camera body, typically with 5 axes of correction (pitch, yaw, roll, plus horizontal and vertical shift). IBIS works with any lens — including unstabilised primes and adapted vintage glass — and corrects more axes than OIS. The image-quality penalty is essentially zero because the sensor isn't cropping or warping the image; it's physically moving to chase the scene.
EIS uses a software crop to leave headroom around the recorded frame and digitally shifts the output to keep the scene steady. It's the most powerful of the in-camera systems at correcting big motion (walking), because it can crop and warp aggressively. The cost is a smaller field of view, occasional warping artefacts at the edges, and slightly softer image quality in heavy modes. Action cameras lean heavily on EIS — GoPro's HyperSmooth, DJI's RockSteady, Insta360's FlowState are all EIS implementations.
A gimbal physically holds the camera and uses motors on three axes to keep it pointing where you set it, regardless of what your arm is doing. Mechanical gimbals are the only system that genuinely produces "floating" footage — the camera doesn't move relative to the scene at all. They are also bulky, need their own batteries, and add another piece of kit to balance and configure. Pocket gimbal cameras like the DJI Osmo Pocket 3 integrate the gimbal into the camera body.
A useful way to think about this: motion comes in three frequency bands, and different systems own different bands.
The reason a handheld camera with strong IBIS still looks shaky on a walking shot is that IBIS owns the wrong frequency band. The big walking motion is too slow and too large for the sensor's mechanical correction range. That's why "Active" or "Boost" modes — which engage EIS on top of IBIS — make walking shots dramatically better but crop in further.
Two big combinations are worth understanding:
When a stabilised lens is mounted on an IBIS body, the two systems coordinate (Sony Active SteadyShot, Canon Coordinated IS, Nikon Synchro VR). The lens handles small high-frequency motion, the body handles roll and larger pitch/yaw. The result is noticeably smoother than either alone. This is why an unstabilised but otherwise excellent prime sometimes looks shakier on video than a stabilised zoom on the same body. Lens choice and IBIS are not independent — see the lenses for vlogging guide for the full picture.
The big mode-name menu items ("Active", "Boost", "Super Steady") almost always mean "IBIS plus an aggressive EIS crop". They produce the smoothest in-camera footage available, at the cost of a tighter field of view and a slightly degraded image. For walking handheld vlogs, the trade is usually worth it. For tripod-mounted talking-head shots, leaving Active mode off preserves the wider lens framing.
In-camera stabilisation has improved to the point where most vloggers don't carry a separate handheld gimbal anymore. There are three scenarios where one still earns its place:
Camera drones use a 3-axis mechanical gimbal between the airframe and the camera. That's why drone footage looks effortlessly smooth — the camera is mechanically isolated from the drone's tilting and rolling in flight. The drone's flight controller handles position; the gimbal handles orientation. The same logic applies to FPV drones with stabilised footage like the DJI Avata 2: even though the airframe rolls and pitches aggressively, the gimballed camera stays pointed. See the drones shortlist and drone regulations guide for the picking and the law respectively.
Stabilisation is one of three quiet upgrades — alongside audio and lens choice — that disproportionately determine whether finished vlogs feel professional. For body recommendations the cameras shortlist is the starting point; the comparison table notes IBIS presence directly. And for the storage side of the equation, see the memory cards for video guide — high-bitrate stabilised modes specifically demand cards above the entry tier.
