In short: use the phone's main (1×) lens, hold it with two hands close to your body and walk heel-to-toe. In editing, stabilise at 50–70% and accept a small crop. Stabilise before reframing or adding zooms.
Why footage shakes
- Zoom magnifies shake. At 3× zoom, every tremor is three times bigger on screen. The telephoto lens also usually has weaker stabilisation than the main lens.
- Walking adds a vertical bob with each step — about twice per second.
- Low light makes the phone use longer exposures, so movement also becomes blur.
- One-handed filming — the phone pivots around your wrist.
Film steadier — the free stabiliser
- Two hands, elbows in. Tuck your elbows against your body; your torso becomes the tripod.
- Walk like a ninja. Knees slightly bent, roll heel to toe, glide rather than step.
- Use 1× and move closer instead of zooming.
- Lean on something — a wall, a railing, a car roof — for static shots.
- Turn on the phone's action or enhanced stabilisation mode for running and sports. It crops more but is very steady.
- Hold each shot for 5 seconds without moving. Fewer, steadier shots beat constant panning.
How software stabilisation works
Stabilisation in editing is a three-step trick:
- Track. Compare each frame with the previous one to measure how far the image moved. VDOAPP does this at low resolution with a sub-pixel search, so it's fast even on 4K.
- Smooth. Add those movements up into the camera's path, then compute a smoothed version of that path. The difference between the two is the shake.
- Compensate. Shift each frame by the opposite of its shake. Shifted frames reveal empty edges, so the whole clip is zoomed in slightly to hide them.
That last step is the unavoidable trade-off: more stabilisation means more crop. VDOAPP limits the zoom to 25% at most, and it calculates the smallest zoom that hides the edges for your specific clip.
Stabilising in VDOAPP
- Trim the clip first — only the part you'll use is analysed.
- Select it, open the AI tab → Camera, set Stabilise strength and press Stabilise.
- Preview. To change the strength, press Remove stabilisation, adjust, and stabilise again.
- Then apply Smart reframe, keyframe zooms or Auto zoom if you want them.
Choosing the strength
| Footage | Strength | Result |
|---|---|---|
| Handheld, standing still | 40–60% | Tripod-like, small crop |
| Walking, vlog | 60–80% | Gimbal-like glide, moderate crop |
| Intentional pans | 30–50% | Keeps the pan, removes jitter |
| Running, bumpy vehicle | 80–100% | Much steadier, bigger crop |
The strength sets how long a stretch of camera movement is averaged — from about 0.2 to 1.5 seconds. Short averaging removes jitter but follows your movements; long averaging produces floaty, gliding motion.
What it can't fix
- Motion blur. A blurred frame stays blurred; it just stops moving, which can look odd. Film in good light.
- Rotation and rolling-shutter wobble. VDOAPP corrects side-to-side and up-down movement — the bulk of handheld shake — but not twisting or the jelly effect of fast vibration.
- Moving subjects dominating the frame. A large object crossing the frame can be mistaken for camera movement. Check such moments.
Frequently asked questions
Should I stabilise footage that the phone already stabilised?
Only if it still looks shaky. Phone stabilisation handles small tremors; editing stabilisation helps with walking bob and zoomed shots.
Why is the stabilised clip zoomed in?
Moving frames to cancel shake exposes their edges; a slight zoom hides them. Lower the strength for less zoom.
Is the analysis done online?
No. The clip is analysed in your browser on your device.
