Magnify part of a video with a zoom lens
Drag a box around a detail and a round lens enlarges it, on top of the full picture. If the detail moves, the lens follows it.
Three steps, a couple of minutes
Drop in your video
A product demo, a replay, a screen recording, a how-to.
Drag a box around the detail
The lens appears over it. Set how much it enlarges, from 1.2× to 5×.
Let it follow
Choose “a moving thing” and the lens rides along. Export when it looks right.
Why use CutLuma for this
The whole picture stays
Viewers see the close-up and where it is at the same time. No cut to a second shot.
Round or square
Change the shape, the rim colour and its thickness.
Pairs with labels
Add a name tag or an arrow that follows the same detail.
Questions? Answers.
Is it free?
Yes, it is part of the free editor and runs in your browser.
Does the close-up get blurry?
The lens enlarges the pixels of your video, so a 1080p or 4K source stays sharper at high zoom than a small one.
Can I zoom the whole frame instead?
Yes. Smooth zooms on the whole picture are under Magic tools; the lens is for showing a detail without losing the wide view.
