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.
 

Quest#1 Why is HD wider than SD , (Standard Definition)?


HD is wider than SD because the resolution and aspect ratio. In High Definition the resolution is 720p - 1080 p with an aspect ratio of 16:9 whilst Standard definition is 480-p width an aspect ratio of 4:3

(aspect ratio is width and height so 16 (width) 9 (height) this is read as for every 16" on screen there is 9" of height and for SD 4( width) 3 ( height) so for every 4" of with there is 3" of height)




Quest#2 When you open Premiere to start a new project ,What setting should you choose?


The default settings in Adobe Premiere uses time-code,audio samples DV. The settings you choose is dependent on what your shooting and the look you want taking into consideration screen size and aspect ratio. So one should choose the settings that will best suite the device; it allows for a perfect fit and clear image.




Quest#3 How do you place a logo in the left hand corner of a clip or still in Premiere?


Firstly by importing the image then placing the cursor over the image and drag it on the timeline and place above the clip then after re-size as needed then place at the top left hand corner.

The panel is called the timeline or video panel.

The other two panels are the option panel and information panel.


Blog#2

1) HD or high definition is wider than SD (standard definition) because its aspect ratio is 16:9, which means that its width is 16, while its height is 9, while with standard definition, its aspect ratio is 4:3, which means its width is 4 while its height is 3.

2) The setting chosen when Premiere is opened depends on the quality and type of video you are aiming for, since the video editing software can be used to fit many devices. There is no one standard setting.

3) A logo is placed in the left corner of a clip, by first importing the image, selecting the logo and moving it to the left of the clip.

4) Transition- Dissolves and Wipe
Motion effects: Rotation and Scaling
Colour effects: Contrast and Keying

5) The dominant layer of audio is always the Top layer.

6) It is necessary to place cursor over selected scene, so that the effect is placed directly where the editor desires it to be, if the cursor is anywhere else, the effect will be placed on that one. It is also necessary, because the editor may only want the effect at a certain part of the scene, therefore, it is very important to observe the placement of the cursor.

7) Clips are added to the Timeline/Video panel, other panels are the Options panel and Info panel.

Quest#1 Why is HD wider than SD, (Standard Definition)?

Answer: HD is wider than SD because the resolution is higher within HD then it is in SD and SD uses higher lines than pixels (for SD 480p, referring to the 480 rows of pixels from top to bottom. HD usually contains 720 or 1080 rows from top to bottom, thus the 720p/1080p designations)The screen is wider in HD then SD because the ratio is higher in HD than SD ( for SD ratio of 4:3 - that means that for every 3 inches in TV screen height, there will be 4 inches of TV screen width. 16:9, which means that for every 9 inches in TV screen height there will be 16 inches of TV screen width.

Quest#7 What is the panel that you add clips to, when making the final project called, name the two (2) other panels

Answer: Project panel (timeline) Tools panel and options panel

Test Part 2

Quest#1 Why is HD wider than SD ?

ANSWER
For decades, television screens have been slightly wider than they are tall-specifically, their ratio of width to height is 4 to 3, which we know as 4:3 aspect ratio from class . Most HDTV screens, on the other hand, have an aspect ratio of 16:9, the same as many movie screens. That means television shows shot in wide-screen will look more cinematic, and many movies will fit on an HDTV screen without letterboxing (horizontal black bars at the top and bottom of the screen). However, there are exceptions, namely ultrawide "scope" movies such as Lord of the Rings and Star Wars, which still have letterbox bars on a wide-screen television. It should also be noted that not all HD programming is wide-screen, and when viewing either standard or high-definition, 4:3 programming on a wide-screen HDTV may get the opposite effect: vertical black or gray bars on the left and right of the screen.

Quest#2 When you open Premiere to start a new project ,What setting should you choose?

ANSWER
By default, Adobe Premiere uses a DV preset for the television standard you specify when you install the program. You will need to select a new preset to create new projects in a different format (such as HDV), television standard (such as PAL), or frame aspect ratio (such as widescreen).
The preset you select becomes the default, so it’s used for all new projects you create, until you select another preset. If you want to use a preset temporarily, be sure to change it when you’ve finished using it. In other words choose a sequence setting that matches the characteristics of your footage in order for it to playback smoother and images sharper. 

Quest#3 How do you place a logo in the left hand corner of a clip or still in Premiere?

ANSWER
A logo is placed in the left corner of a clip/still, by first importing the image, selecting the logo and moving it to the left of the clip.

Quest#4 Match the following

ANSWER
(a) Transition-Dissolves,Wipe
(b) Motion Effects-Rotation,Scaling 
(c) Color effects-Contrast,Keying

  Quest#5 In premiere which layer of audio is dominant?

ANSWER
(c) none of the above

Quest#6 Why is it necessary and highly recommended to place the cursor over the selected scene when adding an effect?

ANSWER
It is necessary due to the fact that the effect may be placed onto another scene which the editor does not want it to be or it may not work if the specific scence is not selected.

Quest#7 What is the panel that you add clips to , when making the final project called , name the two (2) other panels.

ANSWER
Timeline panel/project panel-clips are added to this panel
options panel and tools panel

Question1
What is white balancing, 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. White balance is very important in photography and videography as it gets the colors in your images as accurate as possible.

Question2
 Name 3 of each and explain the difference between Camera and Director's Instructions.

Three Camera instructions are:                          
1) Zoom-
2) Pan- Horizontal movement of the camera, preferably on a tripod to capture a particular scene.
3) Tilt- Vertical movement of the camera,very similar to that of panning.

Three Director instructions are:
1) Action-This commences shooting or recording of the scene.
2) Cut- This terminates the shooting or recording of the scene.
3) Standby- This is used to make the crew aware that shooting is about to begin and is usually said five minutes before the director says action.

Difference

The camera instructions are done electronically while the director's instructions are done through commands-verbally/manually.

Question3

 What is AGC, and what does it do?

AGC refers to automatic gain control it is an adaptive system found in many electronic devices. This is basically where the average output signal level is fed back to adjust the gain to an appropriate level for a range of input signal levels. For example, without AGC the sound emitted from an AM radio receiver would vary to an extreme extent from a weak to a strong signal; in other words the AGC effectively reduces the volume if the signal is strong and raises it when it is weaker.

Question4
If you do not want 16:9 , what is the other option for shooting. and what does it mean?

The other option for shooting would be the aspect ratio of 4:3 which is the universal video format of the 20th Century.

Question 5
When do you open the iris of a camera, what does it do to the camera?
The iris is an adjustable aperture 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. The iris is opened when the individual wants to allow light into a shot. 
Question 6
Apart from white balance, what else should you check before each new scene?
The other settings to check before shooting a new scene would be Resolution, apeture, video quality and Adjust-sharpness, contrast and saturation and  also audio levels if audio is being used.






1. What is white balancing, why do you do it, and what does it accomplish?
- We can instruct a camera to use a particular colour temperature to fulfill our need. This adjustment that makes sure the white colour we view directly will also appear white in the image is referred to as white balance.

2.  Name 3 of each and explain the difference between Camera and Director's Instructions.
- Camera- Tilt, Zoom, Pan
-Director's- Cut, Standby, Action
The difference between the above is that Camera instructions are done electronically whilst Director's Instructions are carried out manually in the form of instructions given on set to the camera crew and the cast.

3. What is AGC and what does it do? 
- this is an adaptive system found in many electronic devices. The average signal level is fed back to adjust gain to an appropriate level for a range of input signal levels.

4. If you do not want 16:9, what is the other option for shooting and what does it mean?
- the other option for shooting is 4:3 which stands for a standard screen.

5. When you open the iris on a camera, what does it do to the picture?
- The iris is an adjustable aperture 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.

6. Apart from white balance, what else should you check before each scene?
- It is always advisable that a camera man check his audio before before shooting and also, camera settings in terms of resolution etc. This will inevitably lead to the quality of the material in the end.

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



The first step one should take before shooting is white balancing as it removes unrealistic color casts. ( This should be done before every shoot, and every time the lighting conditions changes).White balance has to do with differences in color caused by the intensity or temperature of the light and how the camera compensates for these differences in color. So in essence white balance is used to contain the true colour


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



Three camera instructions are :

1)Pan
2)Tilt
Zoom.

Three Director's instructions are:
1) Standby
2)Cut
3) Action

The difference between the two are the way in which they are carried out for instance camera instructions are done electronically whilst the directors instructions are done manually that is with a hand signal.


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



Automatic gain control (AGC) The average output signal level is fed back to adjust the gain to an appropriate level for a range of input signal levels this prevents it from sounding over modulated.


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



Another option for shooting is 4:3 it is used as as universal video format it is known as standard screen.


Quest#5. When you open the iris on a camera, what does it do to the picture?


When the iris of the camera is opened it allows more light to enter the camera.This brightens the picture; the more light is exposed to the brighter it gets if too much light enters the iris it may lead it to be over-exposed .

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




Another check that should be done prior to shooting is checking of camera settings, audio levels another thing the camera person should check to see if the camera is focused

1. White balance, as are all the steps in video production, is very important and must be completed before the start of any video production project. White balance is used in order to establish a starting point for all the colours that will be recording, in a particular project. The purpose of white balance is to ensure that whatever the source of light, the colours of a subject photographed under that light will be reproduced in as realistic a manner as possible.

2. Three camera actions and director instructions used in video production are

Camera Actions:

Panning: This is the horizontal movement of the camera, preferably on a tripod to capture a particular scene. Used mostly to capture a moving object/subject.

Tilting: This is the vertical movement of the camera, preferably on a tripod once again, to capture a particular scene. This is quite similar to panning.

Dolly Shots: These are moving shots, similar to panning shots as the camera follows a horizontal moment to capture a scene. However, in this instance instead of being placed in a stationary position, the camera is placed on a moving vehicle, a trolley for instance, and moves along with the object being captured.

Director Instructions:

Action: This means for the camera person, to start shooting or recording the scene. And for the actors to start repeating their scripted lines.

Cut: This means for the camera person, to stop recording. And for the actor to stop saying their lines.

Standby: This is used to make the crew aware that shooting is about to begin and is usually said five minutes before the director says action.

Camera actions are carried out by the camera person and their crew, they follow the instructions of the director to capture an image/scene. Director’s instructions are dictated an are needed in order to keep some form of organization with in the production setting.

3. AGC or Automatic Gain Control is an adaptive system found in electronic devices, and is used to automatically adjust the volume setting on a device in order to either lower or raise the volume at the right time. This ensures noise reduction when loud sounds are being recorded and allows for extremely soft sounds to be recorded when recording low noises.

4. 16:9 is an aspect ratio with means a width of 16 units and height of 9. It is the most common aspect ratio for televisions and computer monitors and is also the international standard format of HDTV, Full HD, non-HD digital television and analog widescreen televisions. 4:3 is another option for shotting and is now the universal video format for shooting in the 21st century and is universally used for high definition television.

5. By opening the iris of a camera you allow more light to enter the camera and expose the sensor or film. This makes the image appear brighter as it is exposed to a larger amount of light during the period it is being captured by the camera.

6. Before shooting each scene the director and camera crew, should ensure they check the volume and the focus of each recording device, to ensure good sound and picture quality is being recorded each time.

Question #1

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

White balancing may be defined as a process that involves removing unwanted colour casts,it may be done to render natural colours such as red or green correctly. It accomplishes the display of colours in their natural tones that is with the use of white balance colours actually look natural and correct.

Question #2

Name three of each and explain the difference between Camera and Directors instructions.

Three camera instructions are Pan,Tilt and Zoom.

Three Director's instructions are Standby, Cut and Action.

The difference between camera and director's instructions is that camera instructions are directed to the camera itself, how to adjust it or features and presets that the camera needs to be on for a specific production whereas the director's instructions are directed towards persons within or persons working on a production e.g. actors, camera man etc.

Question #3

What is AGC, and what does it do?

AGC or Automatic Gain Control is an adaptive system that may be used to correct color at an output. The Automatic Gain Control can also be used to to adjust how high or low a colour actually is or it may be used to reduce noise ina given frame that the camera wants to actually cover.

Question #4

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

Another aspect of ratio that may be used as an option for shooting is 4:3. 4:3 is used as as universal video format and is standard screen.

Question #5

When do you open the iris of a camera, what does it do to the camera?

The iris is opened on a camera when an individual wants to allow light into a shot, it allows one to adjust the amount of light he/she wants to let in and affect a shot.

Question # 6

Apart from white balance, what else should you check before each new scene?

The cameraman should check the audio and audio levels and exposure.

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

Answer: White balancing a camera is to give a reference to True white; it is done because it tells the camera what the colour white is, so it will record it correctly; based on the fact that all colours contain white light. It accomplishes display of all colours correctly.

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

Answer: The three instruction for the camera are as follow Pan, Tilt and Zoom while for the director they are Picture is up, Action and Cut; The difference between these sets of instructions are One is electronically done and the other is manually done and the camera cannot perform the instructions for the director and the same for the director

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

Answer: AGC is automatic gain control and it take action in increasing the amount of amplification in certain low light conditions; to bring the video signal up to the minimum required level . AGC is not only for that purpose but to reduce noise and picture attenuation, the signal to noise reduced and provide quality picture, which a camera without AGC won’t be able to give a proper working signal.

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

Answer: The other operation for shooting is 4:3 and it means standard screen.

Quest#5. When you open the iris on a camera, what does it do to the picture?

Answer: When the iris is open is allows more light to enter therefore the picture becomes brighter

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

Answer: The other setting to check before shooting a new scene would be Resolution, video quality and Adjust ( sharpness, contrast and saturation) and if audio is being used (ace audio)

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

Camera instructions are Pan, Tilt and Zoom, which is electronically operated by the camera person, while Directors instructions are Standby, Action and Cut and are manually carried out.

When you open the iris of a camera, what does it do to the picture?

The iris or aperture of a camera controls the amount of light which enters the camera. Therefore the opening of the aperture would increase the brightness of the image when shot.

What is the other option for shooting? And what does it mean?

4:3 is another option for shooting, it is termed the aspect ratio, which describes the ratio of a pictures width to its height. 4:3 means that for every four units of width, the picture will be three units of height.

What is AGC, and what does it do?

AGC stands for Automatic Gain Control, which means that the camera will continuously adjust the audio levels so that loud sounds won't overload and distort, and soft sounds won't go unheard.

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

White balancing a camera deals with the adjustment of the camera settings to ensure all colours in the scene be represented consistently. It can be adjusted automatically by the camera or manually by selecting pre-sets or aiming the lens at a totally white surface or grey.

Apart from white balance, what should you check before each new scene?

Before each new scene, the aperture and volume level must be checked, before you proceed to shoot.
