How to stabilise a shaky shot without cropping into it

Last updated 2026-09-10 · 8 min read

What is the short version?

Every stabiliser pays for steadiness with picture. It moves each frame to cancel the shake, which leaves gaps at the edges, and it hides those gaps by zooming in. Keeping the original framing means dealing with the edges some other way.

1. Go to Vizard Agent with the clip.
2. Say it must not zoom, crop or blur the sides.
3. Say what should stay in the centre.

What do you need before you start?

The clip and a clear statement of what you are protecting. "Keep the original proportions" and "keep the waterfall in the middle" are two quite different requirements, and telling Vizard Agent both of them is what stops one quietly being traded away for the other.

• The clip as it came off the camera.
• What must not change. Framing, proportions, duration.
• What should stay centred. The subject, by name.
• Where it is worst. A few seconds is enough.
• Whether a tiny crop is acceptable. Say if it is not.

What do you type into Vizard Agent?

Rule out the shortcuts by name. Asking only for stabilisation gets you the standard trade — a steadier, tighter shot — because that is what stabilisation normally means, and the trade is invisible unless you compare the framing.

Prompt

Variants worth knowing:

• "Do not zoom in." The trade you are refusing.
• "Not blurred at the sides." The other usual shortcut.
• "It shifts at eight to eleven." Locates the worst of it.

What does Vizard Agent actually do?

Here is the order Vizard Agent worked in on a real handheld shot taken from a moving boat. Several approaches get tried and discarded, and the list is worth reading for what does not work as much as for what does.

1. Analyses the orientation and the real frame size of the source.
2. Reviews the result of a first reframing pass on frames.
3. Checks edge-fill options so stabilisation does not enlarge the picture.
4. Checks which stabilisation modes work without zoom.
5. Renders a no-zoom version with a gentle horizontal shift to hold the subject.
6. Confirms the original scale and the subject's position on frames.
7. Replaces mirrored edges with a soft background so the shift reads naturally.
8. Analyses the original camera movement to plan a no-crop pass.
9. Measures the residual shake before locking anything down.
10. Tests locking the framing against the first frame, with no zoom or crop.
11. Renders the strong stabilisation with no zoom, crop, blur or trim.
12. Builds a dedicated lock for the worst seconds against a reference frame just before them.
13. Strengthens that lock so the drift stops being visible.
14. Offers a maximum version with a very light adaptive crop for the edge artefacts.

Step seven is the detail that decides whether this passes. The gaps a shift leaves at the frame edge are usually filled by mirroring the picture, which produces a visible reflected sliver; a soft continuation of the background reads as part of the shot instead.

Step twelve is how a single bad stretch gets handled. Global stabilisation smooths the whole clip and can still let a few seconds drift, so those seconds get locked to a frame from immediately before them — which makes the camera hold the direction it already had.

What does the result look like?

The same shot at the same size, the same proportions and the same length, now steady, with your subject sitting where you asked for it and edges that Vizard Agent filled without announcing that a repair happened at all.

Put beside the original, only the shaking is missing.

When does this not work well?

There is a limit to what can be corrected without giving something up. A violent shake needs more movement than the frame edges can cover, and past that point the honest options are a very light crop or a softer target.

• Violent shake. The edges cannot be covered.
• Rolling-shutter wobble. A different fault, harder to fix.
• A moving subject and a moving camera. Both cannot be locked.
• Very short clips. There is little to measure against.
• Compressed sources. Edge fills are more visible.

How do you fix a result that came back wrong?

Say which seconds are wrong and describe what you can actually see there. Vizard Agent keeps the motion analysis and every attempt it made, so a fix targets that one stretch rather than re-stabilising the whole clip a different way.

• "It zoomed in anyway." Rebuilt in a no-zoom mode.
• "The sides look mirrored." Soft background fill instead.
• "It still drifts at eight seconds." Locked to a reference frame.
• "I will accept a tiny crop." The maximum-stability version.

How does Vizard Agent compare to doing it yourself?

Most stabilisation is one setting with an automatic crop attached, and the crop is applied before you see anything, so the framing loss is discovered by comparing files rather than announced. Locking one bad stretch separately is not a normal option at all.

Common questions

Will it zoom in? Not if you say not to. Vizard Agent uses modes that avoid it.

What happens at the edges? Vizard Agent fills them softly rather than mirroring the picture.

Can it keep my subject centred? Yes. Name it and Vizard Agent holds it in frame.

Will the duration change? No. Vizard Agent keeps the full length.

What if one section is worse? Vizard Agent locks that stretch to a reference frame near it.

Can I have a version with a small crop? Yes. Vizard Agent builds both so you can compare.

Does it work on boat or car footage? Yes, within limits. Vizard Agent measures the movement first.

Will the picture get softer? No. Vizard Agent enlarges nothing, so nothing softens.

Can it fix rolling-shutter wobble? Partly. Vizard Agent will say what is achievable.

Does it change the resolution? No. Vizard Agent keeps the original frame size.

Can it stabilise only part of the clip? Yes. Name the seconds and Vizard Agent leaves the rest alone.

What about the audio? Untouched. For Vizard Agent this is a picture-only pass.

Can it show me before and after? Yes. Ask Vizard Agent for frames from both.

Why does stabilising normally crop? Because cancelling the shake moves each frame, and the crop is the cheapest way to hide the gaps that leaves at the edges.
