Rotoscoping, sounds a fancy term, doesn’t it? If you are into the video editing or Animation field, you are no doubt familiar with the term. It’s a marvelous technique for animators to produce animation from live action videos. Back then, Rotoscoping was performed on glass panels.

What the animators would do, is project live action images onto glass panels and traced them over the images. However, time has changed now due to the advent of the latest technology.  Nowadays, animators rotoscope on computers capitalizing on advanced tools and technology.

Rotoscoping Defined

An interesting fact about rotoscoping is its definition changes from professionals to professionals. What an animation artist thinks of rotoscoping is different from a VFX artist’s thinking. Due to the difference in aim and job, both professionals define the term differently.

In a VFX artist’s mind, rotoscoping is isolating foreground elements like characters or other objects from the background of a shot. On the other hand, an animator thinks rotoscoping is tracing over live action footage frame by frame.

Take a look at an example of rotoscoping in the video underneath-

Wondering what’s the difference between the two? Well, when VFX technicians think of separating the foreground from the background of a shot, they create a matte or a mask to extract characters or objects from the background to use them on a different background.

However, in the case of animation artists, they draw over the live action footage frame by frame to bring out character movement or realistic animation.

Rotoscoping Classification

Before we dive deep into the rotoscoping, it’s crucial to understand the available types of rotoscoping. Over the years, rotoscoping has been deployed in a number of ways to liven up a filmmaker’s vision.

Let’s take a look at some of the types as well as examples of rotoscoping in the film industry:

Reference-based Rotoscoping:

Under the rotoscoping for reference, instead of drawing over the live-action footage, you have to use the footage to get an idea of a character’s movement. Walt Disney did exactly the same for his own company. Disney embraced the strategy and created a reference for rotoscoping.

And the amazing part of it is visible in several Disney movies, including the studio’s first entirely animated film, “Snow White and the Seven Dwarfs.” You will be ecstatic to know that many of the film’s dancing scenes and Prince Charming’s movements were rotoscoped from live-action footage.

Another movie is “Alice in Wonderland,” where rotoscope artists used both an actor’s body movements and their facial expressions to help them animate. On top of that, to save time and effort, Disney artists rotoscoped, specific scenes from the studio’s past animations to produce 1973’s “Robin Hood.”

Rotoscoping- Partial:

As you have already picked up, many animators and VFX teams have embraced rotoscoping technology throughout the years. Partial rotoscoping is a method leveraged by animators to generate an illusion of movement. Depending on the demand for the final product’s look, animators apply this sophisticated method.

For example, an animator may wish to rotoscope a human-like animated character. For that, they have to trace over live-action footage and then supplement it with a caricature to stress the different ratios between animated characters and real human beings. This allows them to bring out more precise movement for a cartoon while maintaining the drawing style.

Filmmakers normally leverage rotoscoping for visual effects to create a matte or mask for a particular element. For example, they can assist to extract an element whether it is a character or object, from a certain scene and place it on a different background.

They also take advantage of the technique to recolor different elements which is one of the many purposes in the world of visual effects. Rotoscoping provides filmmakers with the opportunity to create scenes that are otherwise complex, pricey, or impossible to bring to life.

Why Rotoscope Videos?

Rotoscope besides being a creative tool to leverage in your videos is also a wonderful solution for many filmmaking drawbacks. Rotoscoping can be deployed for multiple creative works like adding special effects, troubleshooting shots, and adding a fun flourish to your video.

Create Special Appeal:

Hollywood movies portray incredible actions in different scenes. Rotoscoping, mingled with green screen and motion picture often produces fantastical worlds we watch on the big screen. Rotoscoping lets the editor cut out elements from one shot and place them in another shot.

Content creators also make use of rotoscoping to create unique compositions and videos. The YouTube channel Corridor Crew frequently leverages rotoscoping and other VFX tools to recreate trailers and upgrade film clips.

Bring out a Unique Style:

Rotoscoping is also a fascinating tool for creating a style for your videos and movies. Do you remember the unique look of the 2006 Richard Linklater movie “A Scanner Darkly”? It was created by deploying rotoscoping techniques.

You can also take advantage of rotoscoping techniques to produce animated flourishes for your projects. No matter whether they are commercials, presentations, music videos, or showreels, adding hand-drawn animations to highlight movement in your shots is a well-known style.

Fix and Upgrade Shots:

Sometimes, you may end up taking a shot with something that doesn’t belong to your composition. Like a stray coffee cup or a randomly placed script, etc. can bring out a haphazard output. In other cases, you may notice something missing from a shot. Rotoscoping can be leveraged to fix both of these issues.

Sometimes the shot may not require fixing, but you wish to alter it anyway for a better appearance. Many YouTube content creators make use of rotoscoping techniques to add elements to TV Shows and Movies.

How to Rotoscope Videos?

Now that you grasped what rotoscoping is, its types, and why you should avail it at length. It’s time to put your artistry to the test. Remember that the steps you follow for rotoscoping depend on the software you’re deploying and the project you’re working on.

However, there are some general steps that you can follow for rotoscoping. Let’s have a look at the steps:

1. Capture and Examine the Reference Film

Before you kick off rotoscoping, you need to decide on what you want to apply the technique, such as a prop or person. Hunt for the scenes you wish to reference to begin the process.

Follow the Useful Tips Below:

If you don’t have a film, get a digital camera to shoot a scene or series of sequences that contain minimum costumes, props, and sets. Why so? This is because having fewer items and simpler backgrounds makes tracing easier.

Make sure the footage features the element or person you wish to rotoscope. Don’t forget to take note of changes in direction or if your main subjects get clouded by other elements as the scene progresses.

Knowing the footage you’re using can aid you to determine your project’s timeframe and how best to commence the rotoscoping process.

2. Choose the Necessary Tools and Software

If you look for rotoscoping software, you will find several to avail. Depending on your project and preferences, select the software that you are the most comfortable with or can pick up as you wrap up your project. Have a look at some examples of software that you can leverage for rotoscoping:

• Adobe Photoshop
• Adobe After Effects
• Imagineer’s Mocha
• Fusion 9
• Blender
• Autodesk Combustion
• Nuke by Foundry
• Silhouette FX

3. Draw over the Reference Film

Once you are done with the selection of your software, lay out the footage and trace the movements or expressions you wish to rotoscope. If you’re using Adobe Photoshop, follow these steps:

Get your Video Timeline Ready:

In order to perform this, open the video timeline from Photoshop’s window menu.

Fix the Timeline Frame Rate:

Make sure to select the right frame rate for your project as insufficient frames could make your animation jerky. However, too many can frame rates will provide you with more work than necessary since drawing each frame takes a lot of time.

Go ahead and Insert your Video Footage:

Now, it’s time to insert your footage. Go ahead and create a new blank video layer. This new layer is exactly what you’ll export as your rotoscoped animation.

Initiate Tracing over the Frames of the Video:

As you trace, try to use as few control points as possible. When you leverage only what you need to trace the object, it helps you to keep track of the points more easily and provide you with a smoother outline as a whole.

If you’re tracing a complex shape, isolate each element if you can. For example, when you trace a body, isolate the body parts that move independently from each other. This lets you create a more precise animation since you’re not using a single outline for a scene.

Set Black as your Foreground Color:

Now, make sure your foreground color is black. Click the Brush tool thereafter and begin drawing outlines for as many frames as you need to create the scene.

4. Don’t Forget to Add Final Touches and Supplementary Elements

Once you’ve traced over the frames, it’s time to use your software’s tools. If you’re carrying out the animation in Photoshop, you can utilize the color fill, masking, warping, and blending tools.

1. Create another blank video layer to add color.
2. Head over to the beginning and fill each frame of outlines with color using the software’s brush tool.
3. Build and set up texture leveraging the blending tool.
4. Finally, you can inject scenery into the background or transition between two successive scenes.

When it comes to using After Effects for visual effects rotoscoping, you can add additional masks to spice up your animation. For instance, if you’re rotoscoping hair, make use of this software’s blur tool to blur the edge of one part of the mask. In order to execute this, follow the steps below-

1. First off, go ahead and add a second mask to the same layer
2. Turn down the second mask’s opacity to 0% when you want it to disappear from the scene
3. Lastly, adjust the feathering to soften the mask’s edge.

If you are a fan of feature films, you must be aware that rotoscoping technique is leveraged in most of these films. This shows that this animation tactic will keep getting popular as time progresses.
