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.
5
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.
