Hi. Im am trying to make a blur filter like "circle blur" only this one has to be square. I am working on some video they needs blurring of faces and shapes in FCPX, and I am finding the Circle blur very useful on faces, but I have tried to make a square blur so I can blur out license plates etc. also.
I have tried EVERYTHING i Motion and I can't seem to make a square blur I can use in FCPX. Can someone PLEASE explain to me how or EVEN BETTER make a filter I can install?
Forever grateful:...

Thanks

A simple solution in Motion or FCP is to add a duplicate layer on top and then add a blur to the top layer and then crop out the image so only the blur area is left. You can also also add a feather to the blurred image too.

There are different ways of achieving this, but the above is the first one that pops in my mind when I need something quick and easy.

For more complicated technique is to use the same technique as above but use a mask instead of a crop. This will allow more customization to the shape.

Hi

Thanks for the tip...
It's KINDDA working now.....I get the square blurred box over into FCPX now and that's great. However....when I want to reposition the blurred box I only get the option to publish the position tool from Motion and I have to do a manual move of the X axis and the Y axis "manually". When I published the Circle Blur filter effect earlier I got an option to publish some kind of "circle" which moved both the X- and Y at the same time. Do you have any ideas as to how I can do this with the square blur?
Thanks

Hello.
Try this effect and please tell me if it works for you, place it in the effects folder.

I did a quick update. Now you can add b-spline shape for more roundness option.
I also added a feather and falloff to blend your blurs better to shot.



Please let me know if you like or if anything else is needed.

I REALLY appreciate you helping me out on this. This is just what I am looking for.
However....is there a way I can position the square on both X and Y at the same time? One the circle blur there is a checkbox in Motion called: Publish OSC, and this gives me the control over both X and Y at the same time.
I have tried linking X and Y inside motion but to no avail
You think you can do this?

Thank you.

Not all the parameters have OSC. Can you send me the one you are using so I can take a look at it.

I have sent you an email.....

Here it is with the OSC for position.
