Storing your CineForm project directly - including
media assets - results in the highest-quality post-production archive.
As testimony to the above, Microsoft's Xbox Live
Download service uses CineForm files for its digital intermediate (mezzanine)
storage. All content delivered by Microsoft's Xbox Live service first goes
through a CineForm file. From the CineForm mezzanine files Microsoft later
renders to VC1 files for download delivery. As of spring 2008 Microsoft
has over 1 Petabyte of CineForm-based online spinning disk storage.
A Note About HDV Exports: From the
perspective of ensuring the highest visual fidelity for your finished project,
we do not recommend rendering your Cineform project back to HDV and storing it
on tape. Remember, HDV is highly compressed and uses a 4:2:0 color space
which is half the chroma resolution of CineForm's 4:2:2 color space. HDV
I/O bit depth is 8 bits. Especially if you're using a Prospect HD/4K or
Neo HD/4K workflow your CineForm chroma resolution is 4:2:2 and your bit depth
is 10 bits. |
