In video editing, stunning design effects help your films stand out. Video bokeh is one of them. If you need to amaze your audiences, bokeh effects are an excellent way to do that.
In this tutorial, you’ll learn how to add a video bokeh effect in full HD. We’ll explore exactly what film bokeh is and how to film it. Then, we’ll dive into a step-by-step look at how to add bokeh effects to already recorded videos.
Let’s get started!
What is bokeh?
Have you ever seen soft, round blurred lights in the background of a video? Well, that is a film bokeh effect.
The bokeh effect in a video is aesthetically pleasing and ethereal. Bokeh is named for the Japanese word boke, which means “blur.” And that’s exactly what it does in night videography.
A video bokeh background is created by adjusting the depth of field in your shots. The advantages are many. It renders any night or twilight video much more attractive.
You can also use video bokeh to focus the eyes of your audiences on subjects in the foreground. After all, if you have a blurry background, your focus will be on those foreground subjects.
How do I capture bokeh effects on camera?
Film bokeh effects can be added in two ways. You can capture it as you film, or you can add the effect later.
To capture bokeh effects, you’ll need an essential tool: a fast lens. But what does this mean?
In short, a fast lens is one that allows lots of light into the camera. This is measured by aperture, so you'll need a wide aperture lens. With this tool, you’ll then want to focus a foreground subject like we described above.
Such focus, combined with a wide-aperture lens, creates the environment you’ll need to achieve a film bokeh effect. You can then begin to capture videos bokeh effects in the background as you film.
How to create a video bokeh effect (Step by step)
You can also add a video bokeh effect in full HD in the post-production. That means that you can add a blurred background with Premiere Pro and similar apps.
My favorite technique is to capture the film bokeh effect on camera, and enhance it in Premiere Pro later.
That’s what you’ll learn in the tutorial guide below. To demonstrate, we’ll work with beautiful stock footage from Envato.
As you can see in the preview, there are subtle video bokeh background effects. What we’ll do in Premiere Pro is adjust them to really enhance them. Let's go!
1. Add a video to the timeline
With a Premiere Pro project open, you’ll first want to add your video to the Timeline. The Timeline sits in the lower center of your Premiere Pro screen.
To add a clip, drag it over the Timeline and drop it into place.
When you do this, you’ll see the video appear in the Program Monitor in the upper center of your screen. In the Timeline, be sure that you’re on the very first frame of the clip.
To do this, click Go to In. You’ll find this button between the Program Monitor and Timeline panels. The clip will then jump to the first frame.
2. Launch the Effects panel and Effect Controls panel
Now, it’s time to set up your Premiere Pro workspace. To add a film bokeh effect, you’ll need to launch two panels. These are the Effects and Effect Controls.
To open the Effects panel, go to the Window dropdown at the top of Premiere Pro. Click it, and from the list of options, choose Effects. You’ll see the panel appear adjacent to your Timeline.
Next, open the Effect Controls. Once again, go to Window, and this time, choose Effect Controls. The Effect Controls will now launch, to the left of the Program Monitor.
3. Add a Gaussian Blur effect
Now, it’s time to see how to add a video bokeh effect to your video. To do this, first click once on your clip in the Timeline to select it.
Then, navigate to the Effects Panel. Inside, you’ll see a list of folders and subfolders.
Video bokeh effects in Adobe Premiere Pro are handled by adding a Gaussian Blur effect to a clip. To find Gaussian Blur, open the Video Effects.
Go to Blur & Sharpen and open it. Inside the Blur & Sharpen folder, you will see Gaussian Blur listed.
To add Gaussian Blur to your clip, click and drag the effect over your clip in your Timeline. Then, drop it into place.
Notice now that the Effect Controls panel includes a dropdown for the Gaussian Blur effect that you just added to the clip.
4. Select the foreground subject
With the Gaussian Blur added, now we’ll select the foreground subject. In this video, the foreground subject is the woman on her phone.
Begin here by going to the Gaussian Blur dropdown on the Effect Controls panel. Directly below the effect name, find the Free draw bezier button. Click it, and move your cursor over the video preview in the Program Monitor.
With Free draw bezier active, begin drawing an outline around the foreground subject. Click once to add a marker point, moving around her head to draw an outline.
As you do, you’ll see a series of blue lines and dots appear. This shows you the boundaries of your outline in real time. Be sure to close the outline by returning to the origin point.
Now, return to the Effect Controls panel. Click the Stopwatch icon beside Mask Path.
Notice that the outline preview disappears. For best results here, click above Mask Path on Mask. When you do, you’ll see the outline preview reappear.
Play your video with the outline preview in view. Depending on how much the subject moves, you might need to readjust the outline. This can be done by moving to a new frame, and then dragging the outline in the Program Monitor.
You can do this as many times as needed, but it’s not always necessary. For a static foreground subject, there won’t be any need to move the outline. But if the subject is in motion, you'll need frequent moves.
5. Control the effect to enhance the video bokeh look and feel
With outlining complete, return once again to Effect Controls and the Mask dropdown. There, find the Inverted check box. Click into it, making sure a checkmark appears.
Then, move directly down to the Blurriness box.
Notice that Blurriness defaults to 0.0. To add bokeh video effects, you’ll want to set a higher Blurriness value.
It’s really a matter of trial and error. Type in a value and hit Enter. When you do, you’ll see the change appear in the Program Monitor.
To amplify the video bokeh effect, go higher with the number. To dial back, go lower.
In this video example, a value of 70 is a good choice. As you play the video back, watch the streetlights, and the lights of the moving bus. Where they were once sharp and crisp, they now have the dramatic and soft video bokeh effect that you’re looking for.
We’re almost done with our Premiere Pro blurred background. But first, you may notice a “halo” around the foreground subject.
This is the result of hand-drawing the initial mask. The halo is essentially an area of sharper focus that is unwanted.
Fortunately, it’s easy to remove. Back on the Effect Controls, experiment with the Mask Feather and Mask Expansion options. By adjusting these values higher, you’ll see the halo fade away.
Again, there’s no default value for this. Experiment by changing both the Feather and Expansion settings. Your progress will be visible in real time in the Program Monitor.
Once the halo is gone, you’re all set! In moments, you’ve learned how to add a video bokeh effect. As you can see, it’s easy to craft dramatic video bokeh effects on your own.
It’s a powerful way to enhance projects with only mild video bokeh effects captured in real time. This edit gives you creative control over your videos’ aesthetic look and feel.
