Abstract: Systems and methods for compressing and decompressing video files are provided. The system includes a digital recording device configured to transfer a digital video feed to a computing device. The system can be applied to the archival and compression of closed-circuit television (CCTV) files. The system includes hardware configured to store and read machine readable instructions. The machine readable instructions-cause the processor to access the digital video feed, extract a series of image files from the digital video feed, organize image files from the series of image files into a grouping of image files, compress the grouping of image files into a singular compressed file, decompress the singular compressed file, extract the number of image files from the decompressed file, and organize the extracted number of image files into a playable video file. The compression may involve use of the Lempel-Ziv-Markov chain algorithm 2 (LZMA2) compression method.
