Hello, in this video, I'm going to show you how you can blur faces in video. You don't have to
just blur faces, you can blur anything you want in video in Camtasia. But let's look at how to
blur faces. I have a video clip here and you can see the people are moving, so they're not static.
And you can go to Annotations and go to this teardrop icon here and you have the blur effect
here. Drag this effect on top of the video, not on the video itself, but on the track above, like
so. Extend the duration for the entire duration of the video, and you can see in my preview here that
I have a blurred area that I can move around and scale. So let's suppose I want to blur this face
here and resize it to the entire size of the face, like so. But of course my video is moving,
so I need to make sure that I can move this around with the face, for example.
This works best if the faces don't move too much and if they do, then you need to adjust it. So the
way to adjust this, you need to add an animation for the entire duration of your clip and move
the object like so. So let's go to Animations and click on Animations and use this custom animation.
Click on it and drag it on your blur annotation, like so. Then extend the end frame and the first
frame to the start and the end of your clip, like so. And at the moment it's not moving because I
haven't changed it yet, but place it to the end and make sure the key frame turns red and move
this blur effect to the face correctly at the end of your clip, and then move it at the start again
and make sure it fits the start of the clip, of the face like this. So then you need to right
click on the animation, this yellow arrow, right click on it, click on Enable Easing and change
the easing to linear. This makes sure that your object, your blur moves at a constant speed.
After you've done this, you need to move your play head around and see where the face is
actually escaping the blur area. And it helps if you zoom in, Control key and mouse wheel
to zoom in. And then all you have to do is just move around and adjust the blur to where it needs
to be with your clip selected. And so, for example here, I need to move it down here,
and if I move back here somewhere, I move it here. You notice, as I'm making changes,
Camtasia adds key frames automatically to my animation and moves it in the place
where it needs to be, and it builds the key frames in-between. Depending on the movement in your
video, you may have to move this quite a lot, but then at some point it's going to work quite nice
and it's going to stay in place. Go again somewhere where you notice it's not quite in place
and move it like this, and like this, and you can see the key frames being created wherever I move.
So this is a sort of motion tracking if you want,
but it is manual and not just the movement, but you can also adjust the size of the object
of the blur effect. At the end, you have a blur area. Let's watch if it works.
So you can see the blurred area follows the face,
and the face is blurred throughout the entire duration of the clip.
If the blur is not strong enough, you can duplicate this track with all the animations
on it. So click on the track, click on the clip with the blur, control + C to copy, go to the
start of your animation and Control V to paste. This actually pastes a duplicate of that. So you
notice now the blur is stronger. If you need it even stronger, paste it again at the start.
Make sure you paste it at the start so that the frames are in sync and the animation is in sync.
You notice now that the face is not recognizable anymore, this is how you blur faces on
videos in Camtasia or moving objects, or maybe car license plates or anything you need to blur,
you can do it with this effect on top of the video
and then track it with the animation to make sure it stays on the subject.
