Methods and systems for automated synchronization and optimization of audio visual files
One variation of a method for autonomously generating an optimized audio-visual (AV) file from an original AV file comprises: a) generating a vector cube comprising a plurality of vector matrices for an original AV file; b) for each vector matrix within the vector cube, determining an optimal subframe having a subframe size larger than or equal to a predetermined minimum subframe size; and c) generating an optimized AV file based on the optimal subframes determined for each of the vector matrices within the vector cube.
