Motion Tracking
Can someone suggest the best method of motion tracking with a blur? I edit tons of films for broadcast and I need to blur out nudity with motion nearly everyday. I have been doing it in FCP with key frames and although this works well, it is very time consuming.

Mocha is fantastic for motion tracking. I know they make mocha for Final Cut, but I’ve never used it. I’ve used Mocha and Mocha shapes for After Effects, and it’s great.

Motion actually has a pretty good motion tracker. I think it would work great for what you’re trying to achieve.

Would know of a good video tutorial for tracking and blurring in Motion. I have not had good success with this.

No, sorry. I don’t know of any tutorials. I read the manual.
What I would do is import the video clip, then duplicate it one layer is on top of the other.
Add a blur to the top layer, then add the mask around the fact.
Do a motion tracking analysis on the bottom layer, then apply the motion tracking to the mask of the top layer.
It’s actually quite simple. You just gotta read the manual.

I was afraid you were going to say that.

If you’ve used Motion before and are familiar with the interface, you’ll find that motion tracking isn’t hard at all.
If this is the first time you’re going to use Motion though, it may be a struggle. Take a day to read the manual and learn the interface. Then learn read about the motion tracking. It isn’t that difficult, it just takes some time. And you’ll feel good about yourself once you do it.
In fact, if you read the manual to learn the interface, you may find the motion tracking to be quite intuitive, because I didn’t even need to read the manual to learn the motion tracking. I just spent a few hours learning the interface and I’ve been good to go ever since.

There is a motion tracking (in Motion) tutorial here on the Cow. I’ve seen it. Not for blurring, but it’s a good tutorial. Dig around and you’ll find it. It show the process for adding car lights “on” to a shot of a car driving towards camera.

Hi,
I had to do a similar thing recently to cover up a logo on a musical instrument. It seemed pretty complex because the camera was panning, zooming, and the light changed all at the same time.
I studied this tutorial, however, and managed to get a very impressive mask to cover up the logo within about 30 minutes. My client was delighted.

I have no affiliation with the author of the site containing the tutorial.
Have fun!
