DUPLICATION, TRANSFERS, CONVERSIONS NECESSARY BEFORE DISTRIBUTION
Post production houses duplicate and transfer entertainment media before distribution.
Telecine transfers involve transferring motion picture film into a video or a digital tape file.
Conversions refer to the encoding system used for television broadcast (NTSC for most of North & South America; PAL for most of Europe).
Specific hardware is available in post houses to effect these duplication, transfers and conversions and ready product for worldwide distribution.
