Week 6 - Muddy

This week was a little more difficult for me, I didn't really know a lot about all the different aspects of multimedia there is a lot more behind it then I ever realized. From learning about all the different sizes and types of multimedia software and knowing which ones to use to best utilize your data. As well knowing which ones can be used on multiple hard drives with out being distorted.

Images was interesting because I knew that some times when I enlarged pictures off my computer they some times look distorted and I learned why this happened because there is two different types of graphics. Raster graphics which are array of colored dotes these are the ones that come out distorted if enlarged and then there is vector graphics which use primitives such as curves, lines, etc. It was also very interesting to know that they use a 24bit for color depth which means there is 16 million different possible colors that can be used in a picture.

The major thing to know about when saving data was whether or not the file will be lossless or lossy. Lossless means its not throwing away any data just reducing its redundancy and lossy means that it removes data that most people will never notice.

For audio the major things to know is its file format there is four different types of file formats for audio data WAV, AIFF, WMA, and MP3 it is important to know which one you are using because of CODEC which is coding when you make the file but as well it needs to be decoded by another computer and you will need to use the same format in order for it to be decoded by some one elses computer.

The video section of this week had a lot of information on it and made you realize how much is put into making sure that your videos can be compatible with multiple computers. Some major things you need to look out for is the aspect ratio which is the size of the video using W:H there are two kinds normal (4:3) and large (16:9). Also you need to know the resolution there is two types interlaced which shows even rows first the odd and has a flickering motion and then there is progressive which goes down the rows in sequence. Then there is frame rate which is the bit size normally ranges from 24-30.
