The Matrix was given a brand new digital transfer in order to give it an appearance far closer to the look of the sequels than the original release. The contrast was improved, film grain was reduced, brightness was elevated in many scenes, and some CG shots revealed more detail. Also, colors were much more vibrant than the original DVD release. The most noticeable change was in the color timing, especially within the Matrix.
In addition, both The Matrix Reloaded and The Matrix Revolutions have received new transfers as well. The images are slightly cleaner and crisper than the original releases, with improved color and detail.
The standard definition collection consists of the following:
Disc 1 - The Matrix
Disc 2 - The Matrix Revisited
Disc 3 - The Matrix Reloaded
Disc 4 - The Matrix Reloaded Revisited
Disc 5 - The Matrix Revolutions
Disc 6 - The Matrix Revolutions Revisited
Disc 7 - The Animatrix
Disc 8 - The Roots of The Matrix
