Step 1: Add Gaussian Blur to your clip
Put your video on the timeline and open the Effects panel (Window > Effects). Type Gaussian into the search field and open Video Effects > Blur & Sharpen. Drag Gaussian Blur onto the video layer, or select the clip and double-click the effect to apply it.
Faster with BetterFX: skip the Effects panel. Press your BetterFX shortcut, type the first letters of Gaussian Blur and press Enter to apply it to the selected clip. Get BetterFX
Step 2: Create a mask around the watermark
With the clip still selected, open Effect Controls and scroll down to Gaussian Blur. Right under the effect name you will see three mask tools: an ellipse, a four-point rectangle and a pen. Pick whichever shape fits your watermark best. A rectangle suits logos and text, an ellipse suits round badges, and the pen is useful for awkward shapes.
The mask matters because it limits the blur to the watermark. Without it the whole frame would turn soft.
Step 3: Move and resize the mask
A new mask appears in the Program Monitor as a blue box. Drag it over the watermark and pull the corner handles until the box fully covers it, with a little margin around the edges. If you cannot see the watermark clearly, zoom the monitor in or switch it to Fit for a better view.
Step 4: Raise the Blurriness value
Go back to Effect Controls and increase Blurriness until the watermark is no longer readable. The default is 0, so nothing happens until you push it up. The video ends up with a high value, around 125, because a faint watermark needs a strong blur to melt away. Pick the lowest value that does the job, since a heavier blur makes the patch easier to spot.
Step 5: Feather the mask edges
Right now the blurred box probably has crisp borders that give the fix away. Open the mask settings and raise Mask Feather so the blur fades gradually into the rest of the picture. The tutorial uses a value of about 57, but the right amount depends on the size of your mask. Increase it until you cannot see where the blur starts.
Step 6: Fine-tune the result
Deselect the clip and play the video back. The watermark should now be gone, replaced by a smooth patch that blends with the background. Go back and nudge Blurriness and Mask Feather against each other until it looks natural. If you shrink the mask, you will usually need less feather. If you grow it, raise the feather a bit.
Tips
- Works best on plain areas. A watermark over a white wall or a soft background disappears easily. Over busy detail like faces, a blur patch stands out.
- This hides, it does not restore. The effect covers the watermark with blur instead of rebuilding the pixels underneath. Only use it on footage you have the rights to edit.
- Moving watermark? If the logo moves around, animate the mask path with keyframes, or use the mask tracking arrows next to Mask Path to follow it.
- Other blur jobs. To hide a face instead, see how to blur a face in Premiere Pro.
FAQ
How do I remove a watermark from a video in Premiere Pro?
Apply Gaussian Blur to the clip, draw a mask over the watermark, raise Blurriness until it disappears and increase Mask Feather so the edges blend in.
Why can I still see the edges of my blur?
The mask feather is too low. Increase Mask Feather so the blur fades out softly, and make sure the mask is large enough to cover the whole watermark.
Can I use a different mask shape?
Yes. Under Gaussian Blur you can choose the ellipse, the four-point rectangle or the pen tool, depending on the shape of the watermark.
