Clipster Gen 6 shines bright with Dolby Vision
The Rohde & Schwarz Clipster Gen 6 mastering station has added new functionality to boost DCI and Interoperable Master Format (IMF) mastering. Content creators now benefit from increased performance with a high-precision colour processing engine expanding the range of colour formats, together with transformations between standardised colour spaces and customised colour formats. In combination with extended IMF J2K profiles for high dynamic range (HDR), the R&S Clipster provides higher resolutions, frame rates and bit-depth compared with the previous generation.
Following a joint collaboration with Dolby, an HDR mastering solution has been created that combines Dolby Vision and IMF. Dolby Vision combines HDR and wide colour gamut, reportedly resulting in brighter highlights, increased light-to-dark contrast and colours never before seen on TV. The R&S Clipster Gen 6 enables Dolby Vision mastering, allowing the metadata to be directly synchronised to the timeline clip and wrapped into MXF. By outputting Dolby Vision metadata via serial digital interface (SDI) to the Dolby Vision content mapping unit (CMU) mapping content to a target display, makes it an optimal solution for QC playback and screening of Dolby Vision workflows.
The R&S Clipster Gen 6 has also increased its performance by offering I/O up to 4K 120p as well as 4K encoding at 60p. The mastering station also offers a complete IMF workflow from a single solution with timeline marker authoring, captions, subtitles and forensic watermarking. The mastering station supports the IMSC1 profile, which is used to simplify subtitle delivery. By implementing IMF in workflows, content providers benefit from the flexibility of file-based workflows combined with the reliability of tape-based production.
