What else can you do with the Warp Stabilizer effect in Adobe Premiere Pro CC other than quickly stabilize footage? In this movie, author Eran Stern take you on a deeper look at the advanced tools of the Warp Stabiliser effect in Adobe Premiere Pro and what you can achieve if we just dig deeper into its controls.
- Now, let's take a deeper look at the advanced tools of the Warp Stabilizer effect, to learn what we can achieve if we just dig deeper into its controls. Now remember, that "advanced" is just something you don't know yet. The moment you understand it, it is no longer advanced, it is just another option or options that you can use in your own workflow. So I'm going to hold down Shift and then using the scroll wheel on the mouse I can drag or scroll the Timeline and you can see that we have another clip over here.
I'm going to select this clip and press once again on the forward slash key or the question mark in order to create an In and Out above this clip. And then I'm going to press play, and I'm also going to move this to full frame so you can get a sense of what we are looking at. And this, of course, was shot from a drone above the Dead Sea in Israel. A beautiful shot courtesy of my friend Moshe Cohen. And this is just one part of the clip, and I picked it because it has these unnatural bounces and shakiness due to the camera operator.
So let's try to use the Warp Stabilizer effect to overcome this in post. I'm going to make sure that the clip is selected and double-click on the effect in order to get Premiere Pro to start analyzing it in the background. And this is also going to be a great opportunity for me to explain more about the advanced options of this effect. So let's just wait for four more seconds for the effect to complete its analysis and then wait for the stabilization to take place.
Now I'm going to highlight the timeline by pressing Shift + 3, and then I'm also going to go to the endpoint of this shot by pressing Shift + I, and then, let's press Spacebar in order to see the final result, which is not final yet, but it is the default result from the Warp Stabilizer. Now, it looks much better, but we may want to give it a little bit more of an extra smoothness. So, you can raise this value, and by the way you can go beyond 100%, but I found out, through trial and error, that 100% in this case should be enough.
Now, Premiere Pro is continuing to play this until the stabilization, or calculation, is finished, and then it will refresh the Program Monitor. Once again, we can see it in fullscreen, in order to see the extra smoothness that we've introduced to the clip. Now, of course, we can check the other method as well. So this is only stabilizing the Position, and we can see that there is big difference because we are not taking under account the Rotation and Scale.
If I'm going to add the Rotation and Scale to the Position, now the stabilization looks much better, but it's still kind of shaky. You can use the Perspective to fix for that, or of course you can use the Subspace Warp if you want to create a really stabilized shot. Now, of course, these are not the only settings that you can change. If you are going to open up the Advanced you can see that we have few more settings that we can choose from.
First, we can ask Premiere Pro to create a Detailed Analysis. This is going to take more time, but if you are getting weird results or you are thinking that the Stabilizer didn't do its best, you can click this and it will take extra time, but you're probably going to end up with a better stabilization. If you have a Rolling Shutter Ripple problem, which is very common to DSLR cameras, then you can try to choose between the Automatic Reduction or the Enhanced Reduction, which usually works better.
Then you can set the tolerance between the Crop Less <-> Smooth More, and those values are usually things that you need to play with in order to see what's working because every clip is going to yield different results. Now, there are three extra options here, which are grayed out, and they will become active once we change the Framing Option. But before doing so, just note this value, this Auto-Scale that tells us how much scaling is applied to the clip.
Remember that we have three other options in terms of the framing. If I'm going to switch it to Stabilize Only, and press Spacebar in order to play the result, you can see those black borders very clearly. You can also see the Warp Stabilization in its full glory. So we can see how the effect is actually warping the pixels. If I'm going to change it to Stabilize and Crop, this will get rid of those weird edges, and will leave us with the image, cropped, using the regular 100% scale.
So this is not scaling the image and not cropping it. But if we're going to use Auto-Scale, then Premiere Pro will auto-scale the image, and because it auto-scales it, sometimes, it becomes a little bit softer. And I will show you how to work around this in a moment, but for now, let's switch to Stabilize, Synthesize Edges. This will keep the scale in 100% and I'm just going to stop the playback because when you choose this method, it becomes very slow, and the reason is because the effect is trying to synthesize the edges, using information from frames before and after the current-time indicator.
So, in this case, we can see that we can define a different Synthesize Input Range in seconds, so if you like to try something bigger, you can go ahead and raise this number, but be careful because every time that you are raising it, even if you are going to get a better result, it will take much more time to calculate the final frame. So you can see that if I'm going to move my mouse over here, the effect is going to take its time, and then we can see the result.
And still, we can see that we have those tiny holes, so we can apply an additional scale, maybe not 118%, let's go with 103%. And now we can see that we fixed the frame and we didn't scale it up. And you can also control the Edge Feather because what the effect is doing is patching this area with a different part of the image that it can find. Now, this is not a magical solution. Sometimes it can work, and sometimes it doesn't.
For example, if I'm going to move my playhead over here, to the end of this clip, and wait for Premiere Pro to calculate the result, we can see that we are still getting those ugly borders over here, and also the edges doesn't look so realistic. So my recommendation, in this case, is to bring back the default behavior, which is Stabilize, Crop, and Auto-scale, and then I'm going to reset the additional scale because I don't want to overscale it because it already scaled up to 118.2%, but I do want to sharpen those details because I'm sensing that part of this information, especially in the ground over here, is a little bit blurred, and in order to see it more clearly I'm going to switch to 100%, and then in order to bring those details back I'm going to go back to the Effects Panel and I'm going to look for the Lumetri effect, this time from the Effect Panel over here and not from the Color Workspace, so you can apply the effect on its own and you don't need to see the whole interface.
In my case, I know exactly what I need to do numerically, so I'm just going to drag and drop it underneath the Warp Stabilizer, and then I'm going to fold down the Creative section, scroll all the way until I can see this Sharpen value, and I'm just going to raise it to, say, maybe 30 units over here. And this is the same as using the Unsharp Mask, meaning that it uses a high-pass filter sharpen method in order to sharpen the pixels, but unlike the Unsharp Mask effect, the Lumetri effect is accelerated, so it can play in real time.
And in order to see the before and after, I'm just going to turn it off, and you can see this is a little bit softer, and here it is with all the details in all its glory. So once again, we can move to full screen, I'm going to fit the size to the dimensions of the monitor, and I'm going to press Play in order to preview the final result. And those were a few of the Advanced Option for the Warp Stabilizer effect, which can help you to stabilize the footage in few different ways, and then preserve more details if you need to, and also restore sharpness, using the Lumetri color effect.
