How to blur part of a screen recording

1. Find the moment.

   Scrub the timeline to where the private item first appears.

2. Add a blur area.

   Text tab → ＋ Blur. A box appears in the middle of the preview.

3. Place and size it.

   Drag the box over the item; drag the corner handle to resize.

4. Pick a style.

   Pixelate (default, can't be reversed), Blur, or Solid box.

5. Set the duration.

   ⇤ Start / End ⇥ use the playhead; or drag the block on the timeline's Text & blur row. Whole clip covers the entire recording.

6. Export.

   Blur areas are included in MP4, WebM, GIF and guide images.

Tips

• The box stays in one place on screen. If the item moves (e.g. while scrolling), add a second blur area for the new position.
• Make the box a bit larger than the item. Pixelation looks cleaner with some margin.
• Overlapping blur areas stack on separate lines in the timeline row, so nothing gets lost.
