[Resolved] How to focus blur?

I need to focus on part of my video and blur around it. I know programs like GIMP have feature called Focus Blur, but I don’t seem to find it in Shotcut. Searching tutorials did not help me either or I did not find the right one.

I need a simple effect like this, what is the trick to make it happen in Shotcut?:


Hi @Viktor_CZ

Shotcut comes with 3 (or 4?) filters sets included in the installation.
One of them is called Obscure with Blur

You can use it to simulate a Focus Blur like you show above.


hi @MusicalBox

that is exactly what I was looking for. The “trick” is saved under the Filter Sets which I’ve never used before, good to know that it is a feature in Shotcut. I guess I will be able to benefit from that in the future if it allow to save your own set of filters too.

Thank you so much for saving my day!

Thanks for this tip, @musicalbox. Never knew. Useful! :+1:


It gave me an idea for a future music video. I can un-blur a section of sheet music and track it along to the music.
This way, I don’t give away too much of the music to the person viewing it.

Thanks @musicalbox, and @Viktor_CZ for mentioning it.
