the HAP Codec

After class, I decided to do a little more research on what the HAP Codec was and how it was useful to our class. I learned that it is a way to enable the user to use many different high resolution videos without causing the computer to run slowly or crash due to not having a good enough graphics card.

There are three different Hap codecs to choose from: Hap offers the lowest data rates for playing back the most clips at a time, Hap Alpha is similar to Hap with support for transparency, and Hap Q offers improved image quality at a higher data rate.

The support for an Alpha channel seems useful for our class since that is one of the 'letters' that we should know and use. I plan to download the Hap Alpha and play around with it - it should make running videos much easier for my computer now.
