  • Do a ball animation with squash effect
  • Render the output in gif format


System requirements

(Slide)

To record this tutorial, I am using
  • Ubuntu Linux 14.04 OS
  • Synfig version 1.0.2


Go to Dash home >> Synfig Go to Dash home and type Synfig.
Click on Synfig logo You can open Synfig by clicking on the logo.
Point to the interface This is the interface of Synfig.
Highlight the Menu bar The Menu bar is located at the top.
Highlight the Standard toolbar The Standard toolbar is located below the Menu bar.


Here, we will find some of the shortcut and handles options.

Highlight the ruler This is followed by horizontal and vertical rulers.
Highlight the Tool box The Tool box is located on the left side of the interface.
Point to the black color box


Point to the white color box

Just below the Tool box, notice there are two boxes -
  • The upper box is in black color.
  • And the tool-tip says it is the Outline color.
  • The lower box is in white color.
  • And the tool-tip says it is the Fill color.


Highlight the canvas In the center, is the canvas. This is where we will do our animation.
Highlight the Animation panel Below the canvas, is the Animation panel.


Here, we can see the buttons that are related to animation.

Highlight the Parameters panel


Point to the Parameters panel

At the bottom left of the interface, is the Parameters panel.


Parameters will be visible once we create an object on the canvas.

Point to Keyframes panel Next to this, is the Keyframes panel.


Here we will add the keyframes.

Highlight the Time track panel

Point inside the Time track panel


On the right of this panel, we can find the Time track panel.


Here we will be able to see the waypoints and the key frame indications of the animation.


Waypoints will be visible once we create an animation on the canvas.

Highlight the Layers panel At the right bottom of the interface, is the Layers panel.
Highlight the Tool options panel Above the Layers panel, we can see the Tool options panel.
Panels above Tool options panel And above this panel, you can find
  • Canvas browser
  • Palette editor
  • Navigator
  • Info panels

<<PAUSE>>

Point to interface We can get accustomed to using all these, as we go along.
Point to the canvas Now, let us start with our first animation.

Draw rectangle on the canvas Now draw a rectangle covering 3/4th of the canvas, as demonstrated.
Point to the Fill color


Highlight the area outside the canvas.

Pls note that the default fill color is white.


Which implies that if we draw outside the canvas, it will be difficult to spot the object.

Point to the Parameters panel Notice that a layer is created in the Layers Panel.


Synfig gives it a name, by default.  


Here it says “Rectangle060Region”.

SLIDE Giving meaningful names to layers is always a good practice.


It helps us to locate a particular object from among the long list of layers.


You will appreciate this more when we create complicated animations.

Point to the canvas Come back to the Synfig interface.
Change the layer name to Sky I will change this default layer name to Sky.


So, click on the name, type Sky and press Enter.

Highlight the layer sky The name of the layer is now sky.
