Gimbal vs Handheld

On ice and snow, the surface steadies the person. The gimbal steadies the phone of the person holding it.

I filmed on smooth surfaces where you slide instead of step: skating on a rink and a frozen lake, and skiing. One clip used a gimbal and five were handheld. I measured the shake in every frame and matched up the clips to see what the gimbal actually adds.

The footage

Six clips, two methods

Gimbal

Indoor rink

Skating alongside teammates at practice, low to the ice.

Phone

Frozen lake

Pond hockey, a skater coming toward the camera, and friends on the ice.

Ski slope

Following skier #18 down groomed runs.

Round 1 · Gliding and following

When you just glide, all three look smooth

Six seconds from each method while the person filming glides behind someone. The numbers under each clip are shake (lower is steadier) and how much the camera is moving.

Left to right: clip A (gimbal, rink) · clip B (phone, lake) · clip D (phone, ski slope)
Gimbal · ice3.9shake while moving the camera 15.6/frame, the most of any clip
Phone · ice0.4shake while the camera barely moves (1.5/frame)
Phone · snow3.0shake while following at 8.9/frame

Your idea holds up. Skates and skis remove the up-and-down bob that walking adds, so a phone held still while gliding looks nearly as smooth as a gimbal.

Round 2 · The hard moments

When you move the camera, the gimbal pulls ahead

Four seconds from the roughest part of each: a fast gimbal pan across the rink, chasing the puck with a phone, and flipping the phone to a selfie mid-run.

Left to right: clip S1 (gimbal, fast pan) · clip S3 (phone, puck chase) · clip S2 (phone, selfie flip on skis)

Vertical shake in the hard moments

Up-and-down jitter from strides, pushes and bumps. This is the part a gimbal cancels.

All three wobble here, including the gimbal. But the gimbal's leftover shake is mostly side-to-side from the motor catching up on a fast pan. That reads as a deliberate whip. The phone's shake is up-and-down jitter.

The big picture

Shake compared with how much the camera moves

Each dot is one matched clip. Farther right means the camera is moving more. Higher means shakier. The gimbal clips sit low for how far right they are.

Side by side

What's the same, what's different

Similarities

  • Gliding works like a camera dolly.Held still while gliding, the phone clips had shake of 0.4–0.6 and no shaky frames at all.
  • Both break in the same moments.Fast pans, flipping to selfie, and pointing down at the puck. The gimbal was shaky in 48% of frames during its fastest pan.
  • Both keep the subject framed.Following someone ahead at a steady distance works with either method.

Differences

  • Freedom to move.The gimbal clip moves about 10× more than the smooth phone clips and still has the least shake for its motion.
  • Different kind of shake.Gimbal: mostly side-to-side (4.9 vs 1.7 vertical over the whole video). Phone on the lake: mostly vertical (for example 0.8 side-to-side vs 2.6 vertical).
  • Handheld falls apart fast.Grabbing for the puck or flipping to selfie took phone clips from 0.4 to 8.6–19.9 shake within a second.
  • Low angles.The gimbal holds a steady shot near ice level right beside players. The phone clips stay at chest height and further back.

Method & data

How shake was measured

Tracking
ffmpeg's vidstabdetect tracked how the image moved between every pair of frames (at 360 px wide).
Camera motion
Average distance the image moves per frame, in pixels. Includes pans and follows you meant to make.
Shake
What's left after smoothing out the intended path over about half a second. This is the jitter you notice.
Vertical
The up-and-down part of the shake.
Shake ÷ motion
Lower means steadier for how much the camera is moving.
