Process

What was done every day?
1/6/12
Today we got an assignment which required us to produce a video of around 5 minutes in duration. The video may be on one of the topics listed below. Successfully completing this task will require your group to create and edit video and audio files and to publish the finished product in an appropriate format. This task will ideally be done in groups of three.
We also had to pick groups and in my group I have Adriana Zeidan. We had chosen the topic "What are Smartphone apps and how to install" 


7/6/12
Today Adriana and I did research on our topic, finding out what are smartphones and some features of a smartphone. 
Here are just a few of the websites we used:


  • http://cellphones.about.com/od/smartphonebasics/a/what_is_smart.htm 
  • http://www.vodafone.com.au/personal/mobile-internet/mobile-internet-basics/what-is-a-smartphone/index.htm
  • http://cellphones.about.com/od/glossary/g/smart_defined.htm
13/6/12 
Today we started on the story board and the script.  Here you can view our story board:

Also we made the script: 
A Smartphone is a device that allows the owner to make phone calls to other phones, It’s like another phone you find, but they also add features. They add features that you might find on a personal computer. A Smartphone also offers the ability to send and receive e-mail and edit Office documents.
Apps are applications which can be used on Smartphones and have been intended to make life easier. The majority of mobile phones, nowadays, are smartphones which have access to these applications. Applications are developed for personal and professional use, there are a variety of apps which can be installed onto the Smartphone’s, such as things ranging from education, business, media, games, etc.
Applications can connect to the internet to perform functions which were originally only made for computers and laptops. Some Smartphone’s start off with the basic apps already installed on them, such as; Web browsing, emailing and accessing phone settings. Even tho there are apps already installed onto the phone, this doesn’t mean the consumer cannot install other apps that they desire, they can install any application on their phone for either a small fee or no price at all, and this is how:

When installing applications onto the smartphone, for apple, the consumer must be aware  that it is necessary to have availability to wifi, and when installing applications the consumer is taking up data from the phone. Before being able to install applications the user must have an apple account which has credit-card details and personal information.
First you must open the app store on the iphone.
Then you have different options on which application to install. You can either pick from featured, categories, top 25 or search. You may be wondering what the updates is for. It is used when you want to renew apps which you have already installed so they become better applications.
For example we could install something from the top 25. Press it.
Then click “top free” so you don't need to pay.
Now decide on what application you would like to install and press it.
Once you have opened it, press “free” “install app” and at this point you will need to put your account email and password.
Insert your details and you have now successfully installed an application.



18/6/12
Today we started drawing the little components which were to be included in the video. And then a few days later we started filming the video.


25-26/6/12
I edited the video adding music and sound to it.



Synopsis

The video explains to the viewer what a smartphone is and the special features the phone contains. It also teaches the viewer how to install applications, also known as apps, onto the smartphone. We have explained how to install them by easy step by step instructions. The video is aimed at teenagers and young adults, as well as people who want an idea on what smartphones are and how to install.

Broadband refers to telecommunication in which a wide band of frequencies is available to transmit information.

2. What units are used to measure bandwidth?



3. How much faster is broadband than dial up?



4. What are the speeds that broadband operates at compared to dial up?

Definition

Stereo-A sound system, typically including a CD, tape, or record player, that has two or more speakers and produces stereo sound.

Channel- Its different sounds or tracks for recording sound such as stereo; left and right channel. Channels of the rear, channel of the front etc.
Track- Is when something is still being edited in software.

Frequency-  the number of periods or regularly occurring events of any given kind in unit of time
Hertz- the SI unit of frequency, equal to one cycle per second

Decibel- A unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level
Wav- shore for Waveform Audio File Format.

mp3- A means of compressing a sound into a very small file, used as a way of downloading audio files from the internet.

aiff- Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers.

Introduction to video notes

Introduction to video notes

1.    What are some advantages of digital video
Digital video is the single most dominant form of live video and image capturing. Its capable of transforming the brightness of the light in a digital signal. To make a photo would not only increase the quality but also the quantity.

2.    What is meant by frame rate in video
Frame rates in videos refer to the speed at which the image is refreshed (typically in frams per second; FPS)

3.    Are all videos/movies the same frame rate, explain your answer
No because not all videaos and movies have the same frame rates. An example would be if someone was running a marathon there would be lots of movement there fore there would be a lower frame rate and would have an effect on quality. But if someone was reading a book there would be little movement and would no have a major effect on quality. The frame rate depends on what is being filmed and the movements/ actions which are being done.

4.    What is meant by resolution, how is it measured.
Resolution is the term used to describe the number of dots, or pixels, used to display an image.
Higher resolutions mean that more pixels are used to create the image. When a monitor's resolution is described, the description generally consists of the number of dots (pixels) contained in each line followed by the number of lines on the monitor. The number of dots per line can be multiplied by the number of lines to identify the total number of pixels displayed by the monitor.
5.    What is the colour system called RGB
The RGB color model is an additive color model in which red, green, and blue light is added together in various ways to reproduce a broad array of colors.6.    Explain the video standards PAL, NTSC, and SECAM, what are the main differences between them.
PAL- (Phase Alternating Line) is the format for the UK and most European countries, except France.
NTSC- (National Television System Committee) is used in North American, Japan, and most of the countires in South America
SECAM- (Séquentiel Couleur à Mémoire—Sequential Color with Memory) Parts of Easter Europe use it.

7.    Which standard do we use in Australia?
the standard commonly used in Australia is PAL

8.    What is an IEEE 1394 port
Its also known as FireWire, its a component originated from Apple which, like a USB, allows the connection of peripherals to a computer, such as video cameras. However, there is one distinct difference. IEEE 1394 supports much higher bandwidth than USB, allowing you to get feed from a high-resolution video camera onto a computer without experiencing issues.
9.    Why do digital video cameras use video compression
Difital video camera's use video compression because once a videao signal is digital, it needs a large amount of storage space and transmission badwidth. Video compression reduces the amount of sata, several strategies are employed that compress the information. It does this without affecting the quality of the image.

10. Describe what a codec is.
It is a microchip that compresses or decompresses data.
11. What is meant by “generation loss”, where does it happen?
Generation loss refers to the loss of quality and potential increase of file size between subsequent copies of data. This occurs with old technology, and sometimes when trying to burn a video from an old camera, each time the video is burnt, the quality becomes weaker and weaker, generation loss.
