EXPORTING YOUR FILM FROM ADOBE PP6

A.

i. How do you export?

•  Before exporting, you have to make sure that all the videos to be exported are rendered. (it should all be green. Also, make sure there isn't; any extra bits you don't want on your timeline. And make sure that; everything is exactly working properly (find files, sounds etc...)

ii. Where do you export to? 

• Click onto the format and choose the following file type (e.g FLV)
• Once it's been loaded, you then click Export.

iii. How do you name your file? Why is this important?

• When naming your file, it has to be labelled as "examplenamev1.mp4" You include your group name, the scene and the version number. 
• This is important as you won't end up having "myadvert.mp4, myadverts.mp4, myadvertss.mp4 etc.."   

iv. What are the different formats? explain, discussing the file size, resolution/quality and purpose- where will it be used and why is that important?

• mp4- It is a compressed file that's used on most video files to use to stream online as well as music that is placed on CDs. the file size is 53.7 MB. You can use the format file on phones, computers, iPod etc..The purpose of this is to be able to have a hd quality of your chosen movie or video. It is important because, it's very handy when it comes to downloading music and you would want to transfer it to your iPod.
 
• mov- mov is a movie format used for Quicktime. It's often used for saving movies and other video files. The file size is 119.6 MB. It's a very common file format to be used with the video cameras as well, and then played on the computer using Quicktime player. It is important because, 
 

• flv- Flash Video (FLV, F4V) is a container file format used to deliver video over the Internet using Adobe Flash Player versions 6-11. Flash Video content may also be embedded within SWF files. There are two different video file formats known as Flash Video: FLV and F4V.

• avi- AVI means Audio Video Interleave, is a multimedia container format introduced by Microsoft in November 1992 as part of its Video for Windows technology. The AVI file type is primarily associated with 'Audio Video Interleave File'. Recent files might be compressed with one or another codecs.  It can also be seen with VLC Player, MPlayer, The KMPlayer. The file size is....

• wmv- Windows Media Video (WMV) is a compressed video compression format for several proprietary codecs developed by Microsoft. The original video format, known as WMV, was originally designed for Internet streaming applications. It cannot be used in the apple Mac. 

B. Converting AND Clipping your video using MPEG STREAMCLIP

i. How do you import your film?

• In order to import your film, you click onto file; Export to (e.g AVI).

ii. Which formats could you use- why is this important? 

• You can export the movie using the following formats; Quicktime, DV, AVI, MPEG.4, Audio, Frame. It is important as you can export your films in different file types so you can upload them in different electronics.

iii. How do you name your files and WHY is this important?

• When naming your file, it has to be labelled as "examplenamev1.mp4" You include your group name, the scene and the version number. 
• This is important as you won't end up having "myadvert.mp4, myadverts.mp4, myadvertss.mp4 etc.."

iv. Why is converting important?
 

• Converting files from one type to another is important so that the file can be
  used by different types of programs. For example you could pull video off off a DVD but iTunes wouldn't be able to play that video unless it was encoded in the correct file type.
   

C.) Uploading Video to Youtube;

i. What is the account name and password- where do you find this information from?

Name; coombeimediastudies
Password; thrasher57

iii. How do you annotate your video?
Firstly, you go onto your Youtube channel, click onto Video manager and your video. Once you're on it, you then click annotations. Then you can continue and annotate however you want.

Task 2- Image file types

 1. Properties of image file types:

• Pixel dimesnion- are the number of pixels wide and the number of pixels tall of a sensor. They are multiplied to find the total number of pixels on a sensor.
• Dpi resolution (Dots per inch)- is a measure of printing or video dot density, in particular; the number of individual dots that can be placed in a line within the size of 1 inch (2.54 cm).
• Quality (of an image)- is a term which often is used to describe the amount of visibility of applicable information in an image. but when we judge an image quality on a camera or monitor, we may look at the sharpness or resolution, good contrast, correctness of colour, stages from black to white what is sometimes called "long scale".
• Compression settings- Compression, or "data compression," is used to reduce the size of one or more files. When a file is compressed, it takes up less disk space than an uncompressed version and can be transferred to other systems more quickly. Therefore, compression is often used to save disk space and reduce the time needed to transfer files over the Internet.

 2. What do they mean:

• Bitmap/Raster- are made up of pixels of different colours. Bitmap graphics composed of many tiny parts, called pixels, which are often many different colours. It is possible to edit each individual pixel.
• Vector- are created in graphics packages and consist of shapes such as objects. Vector graphics are scalable - for example; when you resize them, they do not lose quality. 

What are the diffrences between them? 

Bitmap (or raster) images are stored as a series of pixels. Each pixel is a very small square that is assigned a color, and is arranged in a pattern to form the image. When you zoom in on a bitmap image, you can see the individual pixels that make up that image. Bitmap graphics can be edited by erasing or changing the color of individual pixels using a program such as Adobe Photoshop. However, unlike bitmaps, vector images are not based on pixel patterns, but instead use mathematical formulas to draw lines and curves that can be combined to create an image from geometric objects such as circles and polygons. Vector images are edited by controlling the lines and curves that make up the image using a program such as Adobe Illustrator.Vector images tend to be smaller than bitmap images. This is because, a bitmap image has to sotre colour information for each pixels. But a vector image just has to store the mathematical formulas that makes up the image, which may take less space. Bitmap formats are best for images that need to have a wide range of color gradations, such as most photographs. Vector formats, on the other hand, are better for images that consist of a few areas of solid color. Examples of images that are well suited for the vector format include logos and type.


3. Different file types: 

.tiff- A TIFF file, or TIF file, stands for Tagged Image File Format. TIF files are a common file format for images, especially those used on graphic design. The file extension for a TIFF file is either .tiff or .tif. TIFF files can be saved without compression, or they can be compressed to lower file size, similar to JPG files. TIFF files are commonly used in print design and desktop publishing because they can store large, high quality images such as photos. Often, printers will prefer or require TIFF files over JPG images or other formats. Since compression is not used by default on TIFF files, the file size is generally quite big. This is a big disadvantage of TIFF files. Uncompressed TIFF images can take up a lot more space than a JPEG. This means that digital cameras will not be able to save as many photos in the native TIFF format. It also causes a problem for when sending TIFF's via e-mail, in a lot of cases the attachment size is too big.

.jpg- JPG files, also known as JPEG files, are a common file format for digital photos and other digital graphics. When JPG files are saved, they use "lossy" compression, meaning image quality is lost as file size decreases. JPEG stands for Joint Photographic Experts Group, the committee that created the file type. JPG files have the file extension .jpg or .jpeg. They are the most common file type for images taken with digital cameras, and is widely used for photos and other graphics used on websites. Unlike GIF files, which show significant can lose photo image quality, JPGs allow for some degree of file size reduction without losing too much image quality. However, as the file sizes get very low, JPG images will become "muddy." When saving photos and other images as JPG files for the web, email and other uses, you must decide on this tradeoff between the quality and file size.

.png- Short for Portable Network Graphics, and pronounced ping, a new bit-mapped graphics format similar to GIF. In fact, PNG was approved as a standard by the World Wide Web consortium to replace GIF because GIF uses a patented data compression algorithm called LZW. In contrast, PNG is completely patent- and license-free. The most recent versions of Netscape Navigator and Microsoft Internet Explorer now support PNG. But however,PNG images also do not support animation. PNG can be made into multi-image files through the MNGextension of the format, but browser support is patchy for this format. Therefore, the web designer has to stick with GIFs for creating animations.

.bmp- Short for "Bitmap." It can be pronounced as "bump," "B-M-P," or simply a "bitmap image." The BMP format is a commonly used raster graphic format for saving image files. It was introduced on the Windows platform, but is now recognized by many programs on both Macs and PCs. The BMP format stores color data for each pixel in the image without any compression. For example, a 10x10 pixel BMP image will include color data for 100 pixels. This method of storing image information allows for crisp, high-quality graphics, but also produces large file sizes. The JPEG and GIF formats are also bitmaps, but use image compression algorithms that can significantly decrease their file size. For this reason, JPEG and GIF images are used on the Web, while BMP images are often used for printable images.



.gif- GIF stands for "Graphics Interchange Format," GIFs can contain a maximum of 256 colors, and are therefore best for images that contain simple shapes, a limited color palette, text and other elements as opposed to photos. GIF images use a compression formula originally developed by CompuServe (which is seen as "CompuServe GIF" in Photoshop).  GIF files have the file extension .gif. GIF files are compressed using "lossless" compression, meaning image quality is not sacrificed as file size may reduce. However, if you save images with many colors as GIF files with a limited color palette, you will notice a reduction in quality. Unlike JPG files, GIF files support transparent backgrounds. This allows GIF files to blend with website background colors. But, since pixels can only be 100% transparent or 100% opaque, you cannot use them for partial transparency, drop shadows, and similar effects. To achieve that problem, PNG files are best. GIF files can also contain animation, creating files known as animated GIFs. These are commonly seen on websites, though they are not as widely used as they used to be

.pdf- PDF stands for "Portable Document Format." PDF is a multi-platform file format developed by Adobe Systems. A PDF file captures document text, fonts, images, and even formatting of documents from a variety of applications. You can e-mail a PDF document to your friend and it will look the same way on his/her screen as it looks on yours, even if she/he has a Mac and you have a PC. Since PDFs contain color-accurate information, they should also print the same way they look on your screen. PDF files are especially useful for documents such as magazine articles, product brochures, or flyers in which you want to preserve the original graphic appearance online. A PDF file contains one or more page images, each of which you can zoom in on or out from. You can page forward and backward.
