Film scans and images are usualy shoved about in DPX files. These files embed a massive amount of metadata which can be used to automatically catalog and search in big file collections (and searching is essential since a complete feature film will run well into tens of thousands of files). Reading this metadata can easily help with cumbersome tasks like sorting DPX files per reel/timecode, resolution, selective copying/processing and such daily tasks.

Additionally, depix supports editing of DPX metadata without the need to copy the file over (since files can be big). The metadata gets modified in-place without any copy operations, which is especially helpful when operating across a network.
