In the digital video ecosystem, a "repack" signifies that the original digital file was re-encoded or modified after its initial release. This is usually done to fix a technical glitch (such as audio-video desynchronization), compress the file size for easier sharing, or strip out digital rights management (DRM) protections.

: High compression levels in repack files can cause pixelation, muffled stereo audio tracks, or stripped-out subtitles.
