Creating Animations in Flash CS3

NEW WORDS

Students should extract new words by themselves from chapter No. 1 and write them on neat copies as vocabulary words. There is no need to memorize these words but students should be able to read and understand these words as I explained and discussed in class.

NEW TERMS AND ABBREVIATIONS

Students should learn these terms and abbreviation. It will be the part of exam.

1.    Tweened Animation:

       It is a type of animation in which we define the first keyframe and last keyframe. The remaining keyframes in between are set by Flash CS3 automatically.

2.    Frame-by-Frame Animation:

       It is a type of animation in which we define and set every keyframe manually.

3.    Keyframe:

       It's a critical point of the animation where the object in the video will:

* Appear

* Change

* Begin

* Action

* End

4.    Shape Tweening:

       Using this tool we can change the drawing into another drawing.

5.    Playhead:

       It is a tool that appears in a shape of red rectangle having a vertical line.

6.    Library of Flash CS3:

       It is a folder which stores the symbols of Flash CS3.

7.    Symbols of Flash CS3:

       It is in the form of a graphic image or button or animation which is stored or saved with a video.

Descriptive Type Questions

Q No. 1: Answer the following.

a. How can you identify a keyframe in the Timeline? Write keyboard shortcuts to insert a frame and a keyframe.

Answer: I can identify a keyframe in the Timeline by the black dot that indicates a keyframe.

* F5 is the shortcut to insert a frame.

* F6 is the shortcut to insert a keyframe.

b. How would you delete frames 5 to 10?

Answer: Lab work (will be discuss in Computer lab. Students do not have to do this question on neat copies).

c. How can you convert a robot shape drawn on the Stage to a man?

Answer: I can convert a Robot shape drawn on the stage to a man by using the tool 'Shape Tweening'.

d. Mention two points that should be kept in mind while creating a motion tween.

Answer: Following are the two points that should be kept in mind while creating a motion tween:

1. We must convert the drawing into symbols.

2. We must have to specify the initial and final positions.

e. Evaluate the user-friendliness of Flash CS3.

Answer: Lab work (will be discuss in Computer lab. Students do not have to do this question on neat copies).

f. Create an animation of your choice in Flash CS3 which uses as many of the tools as you know about so far.

Answer: Lab work (will be discuss in Computer lab. Students do not have to do this question on neat copies).

Additional Questions

Q: How many types of images are there? Name them.

Answer: There are two types of images:

1. Analog images

2. Digital images

Analog Images: Analog images are made up of continuous signals.

Digital Images: Digital images are made up of Matrix of pixels.

Q: What do you mean by image file format? Write the names of any three popular formats.

Answer: File format refers to store and organize the digital images. Following are the popular file formats:

1. JPEG

2. PNG

3. GIF

Q: What is the difference between image and digital image? How the digital image is formed?

Answer: When something is visually represented then it is called an image.

But, when we use binary representation of visual data then it is called digital image.

In digital image formation we use a sensor array for the acquisition of the image. When sunlight falls on the object, some rays reflect back and because of this the object has been sensed. All the sensed data will help to generate a continuous voltage signal.

After this process we convert it into digital form by sampling and quantization. The resultant matrix of sampling and quantization form digital image.
