FAILURE :(

Today we continued making progress on the kidnap idea, then by the end of the lesson we lost our enthusiasm and decided we wanted a more interesting topic so we started to think about a new storyline.

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. Anything that reduces the quality of the representation when copying, and would cause further reduction in quality on making a copy of the copy, can be considered a form of generation loss.

In analog systems (including systems that use digital recording but make the copy over an analog connection), generation loss is mostly due to noise and bandwidth issues in cables, amplifiers, mixers, recording equipment and anything else between the source and the destination. Poorly adjusted distribution amplifiers and mismatched impedances can make these problems even worse. Repeated conversion between analog and digital can also cause loss.

10.Describe what a codec is.

Codec is a short name for coder-decoder, the software that takes a raw data file and turns it into a compressed file. Because compressed files only contain some of the data found in the original file, the codec is the necessary “translator” that decides what data makes it in to the compressed version and what data gets discarded.
Different codecs translate in different ways, so a video file compressed using the Intel Indeo codec will be different from a file compressed using the Cinepak codec, for example. Sometimes the difference is noticeable, sometimes not, but it’s good to be aware of what codecs are best for what you’re trying to do in order to maintain the best ratio of file size to quality.

9. Why do digital video cameras use video compression

Many types of video compression exist for serving digital video over the internet and on optical disks. The file sizes of digital video used for professional editing are generally not practical for these purposes, and the video requires further compression with codecs such as the Windows Media format, MPEG2, MPEG4, Real Media, and more recently H.264. Probably the most widely used formats for delivering video over the internet are MPEG4 and Windows Media, while MPEG2 is used almost exclusively for DVDs, providing an exceptional image in minimal size but resulting in a high level of CPU consumption to decompress.

8.What is an IEEE 1394 port

IEEE 1394, also known as FireWire,originated from Apple which, like USB, allows the connection of peripherals to a computer.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. Today, IEEE 1394 has become a computing standard for high-bandwidth devices

IEEE 1394 works through peer-to-peer networking, meaning that devices can connect and talk to each other without needing a computer. IEEE 1394 has the capability of plug-and-play. This means that a device connected to a computer is detected without need of a driver disk or other software.

7.Which standard do we use in Australia?

6.Explain the video standards PAL, NTSC, and SECAM, what are the main differences between them.

5. What is the colour system called RGB

RGB color space

RGB color space or RGB color system, constructs all the colors from the combination of the Red, Green and Blue colors.

The red, green and blue use 8 bits each, which have integer values from 0 to 255. This makes 256*256*256=65536 possible colors.

RGB ≡ Red, Green, Blue

Each pixel in the LCD monitor displays colors this way, by combination of red, green and blue LEDs (light emitting diodes).

When the red pixel is set to 0, the LED is turned off. When the red pixel is set to 255, the LED is turned fully on.

Any value between them sets the LED to partial light emission.

4.What is meant by resolution, how is it measured.

Resolution is Measured in Pixels: The resolution of a monitor is measured in picture elements, or "pixels" for short. Pixels are tiny dots that display on a computer monitor in one of millions of colours, shades and hues. To the viewer, the many pixels in a computer monitor combine to form a viewable picture.

Vertical Measurements: The first consideration in measuring a monitor's resolution is the number of lines displayed on the monitor from top to bottom. While a traditional television display may consist of about 480 lines, higher resolution computer monitors squeeze at least 1080 lines onto the display.

Horizontal Measurements: Each of the many lines measured in Section Two above is comprised of hundreds or thousands of tiny dots (pixels). Generally, the number of pixels contained in a line is proportional to the number of lines in the monitor's display; more lines mean more dots in each line.

Resolution is measured in Horizontal x Vertical Pixels. 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. For example, a 1600 x 1200 display would contain 1600 pixels per line and display 1200 lines. An older monitor that displays resolutions of 640 x 480 would display 480 lines containing 640 pixels each. By this measurement, 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. Using the examples above, a 1600 x1 200 monitor would display 1,920,000 individual pixels. An older monitor with a resolution of 640 x 480 would display 307,200 individual pixels. Because the individual pixels combine to display a complete picture, a higher number of pixels generally mean a clearer picture.

3.Are all videos/movies the same frame rate, explain your answer

Frame rate, or frame frequency, is the frequency (rate) at which an imaging device produces unique consecutive images called frames. The term applies equally well to computer graphics, video cameras, film cameras, and motion capture systems. Frame rate is most often expressed in frames per second (FPS), and is also expressed in progressive scan monitors as hertz (Hz).

2. What is meant by frame rate in video

The frame rate, the rate at which sequential frames are presented, varies according to the video standard in use. In North America and Japan, 30 frames per second is the broadcast standard, with 24 frame/s now common in production for high-definition video. In much of the rest of the world, 25 frame/s is standard.

In film projection, 24 frame/s is the norm, except in some special venue systems, such as IMAX, Showscan and Iwerks 70, where 30, 48 or even 60 frame/s have been used. Silent films and 8 mm amateur movies used 16 or 18 frame/s

introduction to video - 1. What are some advantages of digital video

Digital video has many advantages over analogue video tape due to its great ease of use, portability and durability. The most common usage is presentations which include training, corporate presentations, video kiosks and video libraries. Advantages of using digital video are : Enhanced learning as moving pictures with sound are more effective than stills. Footage can be updated or changed with ease. Digital video adds a whole new dimension to presentations as it can be easily incorporated into computer presentations. With network capabilities, presentations can be distributed easily. Since digital video clips are basically files, they can be integrated into many databases just like text or numeric fields for useful applications. For example, video clips of historical/educational/marketing events or trips can be integrated with more mundane information to provide a more interesting presentation.

the IDEA :D

Today I did a bit of theory then we had a group discussion about the storylines and we all shared one idea then combined it. This combination was a kidnapping. One girl has a fight with her friends at school and is walking home alone, when she gets followed home then her friends come to her rescue. This idea was really good and we all agreed to it.

What did i do today?

Today I did WAAY more theory :D

Discussing storylines

Today I multi-tasked and completed some more of my theory and discussed storylines as a group. This is when Khawab and I presented our ideas and so did srishti and Arusha. No one agreed to all of them, so we decided to come up with an original idea. Here we failed and came up with no genius ideas.

6. Create an image in paint that illustrates how a high bandwidth connection can move more data compared to a dial up connection at a given time

5. What are some of the advantages of using a broadband connection to download something like a video compared to dial up?

The benefits, features and convenience of using ADSL Broadband are enormous. Not only, can you use the phone and the Internet at the same time, but ADSL Broadband is 4 to 26 times faster than Dial-up and your computer is always connected to the Internet. Once you are using ADSL Broadband you'll be able to download music, work files, movie trailers, photos and fancy web pages in a flash. This also means the download speed will be MUCH faster.

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

Usually, the speed is about 20 megabits per second. Now, the speed is developing towards up to even 30 megabits per second. Dial-up used to be SO slow back then, it was actually lower than one megabit per second.

3. How much faster is broadband than dial up?

The benefits, features and convenience of using ADSL Broadband are enormous. Not only, can you use the phone and the Internet at the same time, but ADSL Broadband is 4 to 26 times faster than Dial-up and your computer is always connected to the Internet. Once you are using ADSL Broadband you'll be able to download music, work files, movie trailers, photos and fancy web pages in a flash.

2. What units are used to measure bandwidth?

Bits, bytes and the like are the units of measurement that apply to computer network bandwidth.

http://www.broadbandbuddy.com.au/broadband-learning-centre/bandwidth-whats-what

1. What is broadband?

The term broadband refers to a telecommunications signal of greater bandwidth, in some sense, than another standard or usual signal (and the broader the band, the greater the capacity for traffic). Different criteria for "broad" have been applied in different contexts and at different times.

Photos

Today are the photo's for maths challenge so we need to leave class early to maeke it in time. But we are doing some research before we leave.

with khawaaab

lesson with discussion with khawab about what to make video abouut.

and more theory work...

Today I conitued on with my theory work.

Joining groups :P

Today srishti, khawab, arusha and I realised that we could actually join together to form a group of four as this is would enable greater success and more innovative ideas for our film. SO we combined groups then continued with our theory work.

Doing more theory work

Today Khawab and I continued with some of our theory work.

Audacity

Today in class i installed the Audactiy sound editor and started experimenting with it. Mr cavill had to help me a few times but now im having alot of fun ! :D i tried editing te amo first (experiment song)

c)The types of software available as portable applications.

4. Compare the quality of AM, FM and Digital radio.

Digital radio works by turning both sound and data into digital signals at transmission, and then decoding them at the other end using digital radio receivers. The result is close-to-CD-quality sound output. While AM/FM radio quality can suffer from interference caused by signals bouncing off walls, buildings, hills and other structures, digital radio receivers have built-in technology that cleans and filters transmissions, making interference practically non-existent. What's more, with data now able to be sent as part of the signal, digital radio receivers with LCD screens can also give listeners information such as song names, cover art, news, weather and more. In fact, the new DAB+ standard gives you the ability to rewind broadcasts by up to 15 minutes. Digital radio has the potential to offer better sound quality that's better than FM - and much, much better than AM - and it is interference free. Which also means you either get signal or you don't. Digital radios are also easier to tune - instead of fiddling with a dial to find the strongest frequency for a station, listeners will be able to choose a station by name from a menu, with the digital radio automatically locking on to that signal at a push of a button.

3. What unit is used to measure sampling rate?

The rate at which the samples are captured or played back, measured in Hertz (Hz), or samples per second

2. What unit is used to measure sample size?

Hertz (Hz).

Making storylines :)

Today I and Khawab made some possible storylines. I wanted some romance and Khawab wanted action. So we combined these ideas and made the life of a secret agent who is in love with his seductive enemy. Also, a violent couple (inspired from Mr & Mrs Smith) and a couple who are superheroes.

When everone was away...

Today in IST I was working on some of my theory work and completed one exercise as Khawab was absent (at MAG)

Audio sampling rate and sample size - 1. Sound moves through what medium?

Today i did some research in class on audio sampling rate and sample size. I then answered

the questions.

 

Sound travels faster in a denser medium, so sound travels most rapidly in steel. However, since sound is a longitudinal wave it is medium dependent, meaning that a medium must be present.

Gaining knowledge about the project

Today sir let us know that the groups were to be from 2 – 4 people in one group. My friends and I were discussing our groups but were unable to come to a conclusion. So one member decided to join another group whilst the remainder, put our names in a hat. This didn’t work either because we were unhappy with the results. Then Karin and Navneet decided to work together and Arusha and Srishti decided that they were already planning to make something related to a vampire show, so they combined as a pair. Leaving me and Khawab to work as partners. Now that our groups were decided, I made a new blog on my account called khawab&aishwarya for this particular project. We then made our first blog post as a pair.

first lesson

Today we decided which groups we would be in, at first we were quite puzzled and confused as to

who we would work with but then finally we reached the conclusion that we ( khawab and aishwarya ) would work together). Then we realised that this meant, we would need to overlap tasks because we needed to both perform inn the movie and needed a camera person aswell. But first we had to decide the concept of the film. So far we are thinking about having a love story with the male character being Khawab and a female character being Aishwarya.

Term 2 project

Today in IST, Mr Cavill told us that this terms project was to make a video with a topic our topic of our choice. This video would be 5 – 10 minutes in length and should include ALL group members with the consideration of having a camera person. He then told us, that we would require background knowledge before starting to film our video, so we were to start our theory work.
