The Problem Large video files look nicer but require more space to store and send over networks Smaller files look worse but require less space The tricky part is finding a balance between the two

Software Xvid https://www.xvid.com/ is an open-source codec MP4 codec Sample video files Software to play videos

Hardware A few devices on which to test video quality. No hardware needs to be purchased.

Some Starting Points Increasing size of blocks for discrete cosine transformation. Lowering quality on outer edges of video specifically where human eyes are less likely to look. Increase number of prediction frames. Learn and experiment.

Timeline October 21: Be familiarized with the Xvid codec, how it works, and how to make simple modifications to it to change compression. November 6: Have unique, decently working, personal compression algorithm. At this point I will have explored Xvid and experimented with ideas for some time, so I hope to have added some of my own ideas to the codec. November 8: Complete a general outline of the paper to serve as a guide. November 16: Complete the first draft of the paper. November 30/December 4: Be prepared for project presentation. December 12: Finish second draft of paper. December 16: Finish final draft of paper and software.
