Join Maxim Jago for an in-depth discussion in this video Stabilize a shot, part of Media Composer 8.7 Essential Training: 101.
- [Man] Some of the segment effects in Media Composer are fairly straightforward. Throw them unto a clip and you can adjust the settings in the effect editor. Some of the effects, like the one we're going to look at now, preform some automatic analysis of your content and they use the output of that analysis to change the way the effect is configured. We've got a shot here that is okay, it's pretty good, but we have a little bit of camera shake in it. I'm going to click back to the start of the clip, just this one, around about 20 seconds in this stabilizer shot sequence.
And have a look at the playback, watch this in the program monitor. Now it's okay, it's pretty good, it's quite short. But there is a little bit of camera movement and we're going to use the stabilizer effect to fix it up. So over in the project window, inside our effect palette, I'm going to click in and I'm going to start typing "stabilize." I don't need to type the whole word, it's going to come up right away. And I'm going to drag and drop this unto the clip, however before I do, I want you to watch carefully what happens in the picture.
So here we go, I'm dropping this one right now. And hopefully you saw that. We had lot of little green dots popping up in the picture. Those dots are Media Composer analyzing the shot and identifying where movement is. And two new windows have popped up. We've got the tracking window and we've got the effect editor. Now we've seen the effect editor before, and it's pretty straightforward. We've got the controls associated with this effect, displayed. Here's the icon for it at the top.
And we've got some scaling options and positioning and so on. Notice that the scaling has automatically been set to 107%. And here's how the stabilizer effect works, the effect looks at the image and tracks details in the image to identify the movement of the original camera. The effect then applies exactly the opposite movement to the clip itself, so that it apparently doesn't seem to move anymore. So if the shot moved five pixels to the left, because that's what the camera was doing, then the system is moving the actual clip five pixels to the right, to compensate.
And it does this pretty effectively. This little line, you can see this little squiggle in the middle of the picture, is a motion path. That's the path that the video clip is taking as it shuffles around the screen to compensate for the original camera movement. It turns out that the camera movement wasn't too bad, because the system only had to increase the size of the video by 7% in order to cover up the edges as it shuffles the image around the screen to compensate.
If I turn this scaling option off and just drag through the clip, you can see what Avid has done. It's not an enormous amount of movement, I've seen a lot worse with this effect. But you can see, this effect is really ideal for shots that were, perhaps originally, not intended to be moving, but there is a little bit of wobble there because it's maybe a handheld shot. Just going to turn the option back on, but hopefully you can see what's going on there. It's pretty impressive technology. Turn back on the scale.
I'm going to close this tracking window and I want to mention, just before I close the effect editor, that we've got access to the tracking tool right here over on the right in the effect editor. If I click this, we go straight back in. I'm going to close this again and close the effect editor and I want to show you another shot, so here, on the timeline, the next clip also has some movement. I'm going to play this. Now again, it's pretty short. I'm just zoom in a little on the timeline here, so we can see it a little better.
And again, this is a shot that the camera operator probably would've preferred to have fixed, either on a tripod or a monopod even, but didn't, it's a handheld shot. Let's say the director decides that they would like it to be absolutely still. We really want to audience to be focusing on this guy's face and not the movement of the camera. So I'm going to apply the same effect, I'm going to take this stabilizer and I'm going to throw it unto clip. There's the analysis, it's very fast.
And this time, I'm going to turn off one of the options, "enable steady glide." This option maintains some of the movement from the original camera work. And it means that instead of having an absolutely locked-off shot, Avid allows just a little bit of movement, but it smooths it out for you automatically. It make it looks deliberate. Going to drag back a little bit here. This is our effect preview window now, remember, because we got the effect editor open.
And I'll play through the clip. And we can see, we've got a little bit of movement, but it is smooth. We zoomed in, a fair bit. Let's turn off our scaling option in the effect editor and you can see that camera movement is a bit more significant with this version. Let's turn that back on. And back in the tracking window, I'm actually going to turn steady glide off, and this means that I'm asking the effect to absolutely lock-off the shot and compensate for all of the camera movement.
And you can see from the motion path, in the middle of the picture here, this is with the steady glide on, so there's less compensating movement. And here's with the steady glide off. You can see that the effects is doing more work, in fact, if I turn off the scaling option here in the effect editor, you can see just how dramatically the effect is having to move the video clip around in the frame. But the result is a totally solid shot. We're up to 115% here in the effects editor of the scaling, let's turn this back on and take a look at the shot.
Completely static. Once again, there are other options in this effect and you can do a lot with the tracking window and the stabilize options in Media Composer. But for now, I'll close these down and it's good to know that if you just want to make it look okay, you can use the stabilize effect and have a very reasonable, automatically generated result.
