Intro

Onion skinning is a technique, accessible in the Dragonframe software, that enables animators to simultaneously see several of their most recent frames in Live View. Onion skinning is essential to accurately have fluid animation as it allows you to see your previous frames so that you can make a continuous movement when making new ones.

Settings

When opening Dragonframe, you will find a tool called the Onion skin Opacity Slider, which is located underneath the Live-View (see Fig. 1.0 & Fig. 1.1). The Onion skin Opacity Slider lets you control the opacity of your previous animation frames.

(Fig. 1.0)

(Fig 1.1)

The red dot in the center of the Onion skin Opacity Slider (Fig. 1.1) is on Live-View.

(Fig. 1.2)

(Fig. 1.4)

(Fig. 1.3)

Moving the red dot to the right, lowers the opacity on the Live-View (Fig. 1.2).The previous frame will appear when the red dot is moved to the far end (Fig. 1.3).

(Fig. 1.5)

Moving the red dot to the left, transitions the live view to the selected frame (Fig. 1.4). This happens if the first frame is selected on the X-Sheet (Fig. 1.5).

Onion Skin Modes

At the bottom right of the Onion Skin Opacity Slider, there is an icon depicted in Figure 1.3 that, when clicked, opens up the Onion Skin Modes (Figure 1.4).

(Fig. 1.3)

(Fig. 1.4)

Onion Skin Modes:

Normal - The standard onion skinning mode.
Frame Echo - Frame Echo allows you to see up to six of your most recent frames that you took through the Live-View by sliding the small grey circle (see Fig. 1.4) to the far right (see Fig. 1.5 & 1.6)
Darks - By activating Darks, the darker colors become more vibrant.
Lights - By activating Lights, the light colors become more vibrant.
Difference - If the frames are the same, the images become black.

(Fig 1.5)

As you can see in Fig. 1.5, a series of frames are stacked on top of each other.

By activating the Frame Echo, we see that the darkest circle (bottom right) is our most recent frame while the rest of the stack lies behind in order.

(Fig. 1.6)

Onion Skin Examples

2D Lab

2D Animation (Hand-Drawn)

For 2D Animation, we will use a hand drawn circle to demonstrate how Onion skinning works. Be aware that if the lines are darker, then it's on the Live View when the onion skin is activated.

(Fig. 2.0)

(A GIF example of 2D Animation without onion skinning.)

(Fig. 2.2)

1. The first frame (Fig. 2.2), without the Onion skin, shown in the Live-View.

(Fig. 2.3)

2. Right after taking the shot of the first frame, the opacity is lower. The second frame (Fig. 2.3), with thicker lines, has been drawn and ready to be taken as a shot through the Live-View, while the previous frame is pushed to the background.

(Fig. 2.5)

3. Right after taking the frame shot of the second frame, the opacity is lower. The third frame (Fig. 2.5), with thicker lines, has been drawn and ready to be taken as a shot through the Live-View.

(Fig. 2.6)

4. Right after taking the frame shot of the third frame, the opacity is lower.The fourth frame (Fig. 2.6), with thicker lines, has been drawn and ready to be taken as a shot through the Live-View.

(Fig. 2.7)

5. Right after taking the frame shot of the fourth frame, opacity is lower.The fifth frame (Fig. 2.7), with thicker lines, has been drawn and is ready to be taken as a shot through the Live-View.

Realigning The Stand

Another useful thing to note when using onion skinning is the ability to align your artwork in position within the frame when re-opening your Dragonframe folder. This is helpful to use if the Main Animation Desk or the height adjustment (that holds the camera) has been bumped or altered.

To re-open your Dragonframe folder, open the Dragonframe software.
Select Open Scene.
Select your Dragonframe folder saved on the Desktop.
Select Open Scene.
Once Dragonframe is open, select your last frame and adjust the Onion Skin Opacity Slider.
With the Onion Skin Opacity Slider, moved the red dot midway to the right.
Place your animation drawing that you used for the frame and align your artwork in Live-View.
Adjust the Main Animation desk if needed.

3D Lab

3D Animation

By using this puppet, we will only be moving its arms as an example for using Onion skinning for 3D Animation.

(Fig. 3.0)

(A GIF example of 3D Animation without onion skinning.)

(Fig. 3.1)

(Fig. 3.2)

1. The puppet repositioned to be taken as the first frame (Fig. 3.2).

(Fig. 3.3)

2. After taking the shot of the first frame, the opacity of the arms are lower when moving the arms. Right after repositioning the puppet (Fig.3.3), it is now ready to be taken as a second frame through the Live-View.

(Fig. 3.4)

3. After capturing the second frame, the arms repositioned and is ready to be shot as a third frame (Figure 3.4).

(Fig. 3.5)

4. The arms repositioned to be shot as a fourth frame (Fig 3.5).

(Fig. 3.6)

5. The arms repositioned to be shot for the fifth frame (Fig. 3.6).

(Fig. 3.7)

6. The last and final shot of repositioning the puppet (Fig. 3.7).
