Quiz3



QUESTION #1
 What is a key frame and why is it important?

ANSWER
Key framing can be referred to as the process of assigning a specific parameter value to an object at a specific point in time. For example, you might want a clip to be scaled to fill the screen exactly five seconds into your project. I found that a key frame is very important due to the fact that when you set more than one key frames, motion generates the in-between frames, resulting in a smooth change of that parameter over time. This is called interpolation. For example, if you want a title to change from purple to yellow over time, you would set two keyframes at two different points in time. The first one would define the text’s color as purple, and the second keyframe would set the color to yellow. Motion automatically makes the frames between those points change smoothly from purple to yellow.

QUESTION#2 
How do you set a key frame ?

ANSWER
The basic idea is to create more than one key frames, then set the desired effect values at each keyframe. Premiere will create a gradual change in values between keyframes (this is known as interpolation). For example, you could create a keyframe where the volume is -20dB and another keyframe 5 seconds later where the volume is 0dB. Premiere will interpolate this to create a smooth five-second volume increase.There are two ways to view and work with key frames: In the Timeline and in the Effect Controls window. Key frames can be displayed in the timeline when a video track is expanded- a line is shown with small diamonds marking the key frames.I found this to be a relatively easy, intuitive way to view and manipulate key frames. However, key frames can only be shown for one effect at a time and control is not as precise as using the Effects Control window. Therefore, For full control over key frames, select the clip in the Timeline and open the Effects Control window. The right-hand side of the window is a miniature timeline, just for the selected clip, which shows key frames as diamond icons as well. I found it difficult to get use to but it allows you to see key frames for all effects at once and provides excellent control.

QUESTION#4 
Which of the following cannot be set with key frames?
1) Opacity 2) Volume 3) Rotation 4) Contrast 5) Scale

ANSWER
Almost any effect can be set with key frames therefore, all the above effects can be set with key frames.

QUESTION#5 
What is the band that is used to control volume on an audio clip called?

ANSWER
You can monitor audio levels for clips in a Timeline panel. If the Audio Master Meters panel is not open, select Window then Audio Master Meter,Select the Program Monitor or a Timeline panel and do one of the following: Press Space or in the Program Monitor, click the Play Stop Toggle (Space) button . The Audio Master Meters panel displays the audio level for the Timeline.
QUESTION #6
What is the keystroke used to set key frames.?

ANSWER
CTRL K

QUESTION#7 
What two panels can you use to set key frames ?

ANSWER
The two panels one can use to set key frames are the timeline or the effects control window.

Quiz #1---620025726

Question #1: What is white balancing a camera, why do you do it, and what does it accomplish?

White balance basically means colour balance. It is a function which gives the camera a reference to "true white;" it tells the camera what the colour white looks like, so the camera will record it correctly. Since white light is the sum of all other colours, the camera will then display all colours correctly. White balance is really the process of removing unrealistic colour casts; hence it is done so that objects which appear white in person are rendered white in the photo and give it an even and accurate look.

Question #2: Name three of each and explain the difference between camera and director’s instructions.

Camera instructions are pan, tilt and zoom which is done electronically by the camera while Directors instructions are Standby, Action and cut which are manually carried out by the director.

Question #3: What is AGC and what does it do?

Automatic Gain Control is a circuit found on some electronic devices that automatically controls the gain of a signal. Using AGC means that weaker signals receive more gain and stronger signals receive less gain or none at all. AGC allows the camera to configure what it feels the best sound recording level is for a particular scene. It will try to adjust itself to various sound changes within a shot.

Question #4: If you do not want 16:9, what is the other option for shooting and what does it mean?

If you do not want to use 16:9 you can use 4:3. This is the native format of many camera sensors. It is ideal for showing on most computer screens, tablets, and printing to 8.5 x 11 paper or magazine and other print media.

Question #5: When you open the iris on the camera, what does it do to the picture?

On a digital camera iris is an adjustable aperature used to control the amount of light coming through the lens. The more the iris is opened, the more light it lets in and the brighter the scene will be.

Question #6: Apart from white balance what else do you check for on each new scene?

It is wise to check the audio on the camera before shooting so as to save time. It is also vital that you check the resolution on the camera and if the camera is focusing on the subject in order to have a good quality video.

Quiz #1 620016571



Quest#1. What is white balancing a camera, why do you do it, and what does it accomplish?

White balance (WB) is the process of removing unrealistic color casts, so that objects which appear white in person are rendered white in your photo. The camera attempts to determine the color temperature of the light and automatically adjust for that color temperature. The reason we adjust white balance is to get the colors in your images as accurate as possible.

Quest#2. Name three of each and explain the difference between, Camera and Directors instructions.

Three Camera instructions that are utilized are;
1. Tilt: A tilt involves tilting the camera up or down.
2. Dolly In: To move the camera closer to the subject, you dolly in.
3. Pan: A pan is a turning of the camera to the left or right.

Three Director Instructions are;
1. Standby on the set
2. Action
3. Cut

Camera instructions are usually carried out by the camera crew who are responsible for physically operating the camera and maintaining composition and camera angles throughout a given scene or shot.  The director on the other hand oversees the entire production and all its operations.

Quest#3. What is AGC, and what does it do?

Automatic Gain Control (AGC) is used to automatically adjust the speech level of an audio signal to a predetermined value. It regulates sound input to give leverage to sounds too loud or sounds too soft.


Quest#4. If you do not want 16:9, what is the other option for
shooting. and what does it mean?

16:9 Aspect Ratio is the international standard format of HDTV, Full HD. Another option to explore when shooting is 4:3 Aspect Ratio, which is the conventional format that is still utilized by most TV networks. The difference in shape between those two ratios can result in a "pillar boxed" picture.

Quest#5. When you open the iris on a camera, what does it do to the picture?
We use this to decide how light or dark to make an image. When we close the iris, less light enters. Use an OPEN iris in DARK situations. Use a CLOSED iris in bright sunlight, or under heavy studio light.


Quest#6. Apart from white balance, what else should you check before each new scene?

When shooting a video, other than checking for the white balance, one should also verify that there is sufficient film for the scene, check the audio levels so as to achieve good sound quality, ensure that all the equipment is connected.

Quiz #2

1. HD (high definition) is wider that SD (standard definition) video because of the aspect ration used to define both types of video. SD videos used a ratio of 4:3, this means the height to width ratios in SD videos is 4 width by 3 height. This is relatively small and as a result does not expand well to be shown on larger scales. HD videos contain more pixles then SD videos, this makes expanding HD videos easier than SD videos. The aspect ratio used in HD video is also significantly larger than SD video, with a width of 16 and a height of 9.

2. When working in Premiere there are a number of settings which you can choose from when producing a video project. However, the DV setting is seen as the best standard setting to use when working with videos in this program. DV creates videos using standard definition 4:3. This setting is compatible with most television sets worldwide. HDV which is high definition video would be the next best setting to choose for a better quality in image, however, you must be sure that the target audience can view the video.


To place a logo in Premiere, you must first import the logo into the timeline, and then position the image using the tools available to position the image to the left of the clip.


4. Transition: Dissolves & Wipe

Motion Effects: Rotation & Scaling

Color Effects: Contrast & Keying


5. The dominate layer of audio is Premiere is the top layer.


6. When edition a particular scene in Premiere, the section of video must first be selected before an effect can be added. If the scene is not highlighted the effect will not be correctly inserted into the frame, and may even be inserted into the wrong scene or not added at all.


7. The panel in Premiere that is used when adding clips is called the timeline or video panel. Two other panels that are used in Premiere are the option panel and the information panel.

1. Why is HD wider than SD?
- HD is wider than SD because the resolution and pixels are much higher.

2. When you open Premier to do a project, what setting should you choose?
- Firstly, you open a new project...then this brings you to a list of settings, here you have video display format and for this you choose time code. Next is audio an for this display format you choose audio sample, for capture format you choose DV. Finally, you choose the location and name the project.

3. How do you place a logo in the left-hand corner of a clip or still in Premier?
- Firstly, you import the image into Premier, then you place the cursor over the image and drag it to left hand side.

4. Match the following:
-(a) Transition- Dissolves, Wipe
(b) Motion Effects- Rotation, Scaling
(c) Colour Effects- Contrast, Keying

5. In Premier, which layer of audio is dominant?
- None of the above.

6. Why is it necessary and highly recommended to place the cursor over the selected scene when adding an effect?
- This is important since you would not want that specific effect to go on another layer.

7. What is the panel that you add clips to when making a final project?
- The panel that you add clips to when making a final project is the project panel or timeline.

(b) The 2 other panels are the Tool Panel and Option Panel.
