Dirac is versatile. It is difficult
to think of an application that cannot be covered. We suggest you
try Dirac for:
- Broadcasting
- Clip Distribution
- Live Streaming Video
- Pod Casting
- Creative Archive
- Peer to Peer transfers
- HDTV with SD Simulcast capability
- Higher density channel packing
- Desktop Production
- News links
- Archive Storage
- Digital Intermediate Film Out file storage
- PVRs
- Multilevel Mezzanine 3 GBit/s into 1.5 GBit/s,
1.5 GBit/s into 270 MBit/s etc
Dirac provides support for all the formats that may be used
in broadcasting and much more. If you want something to be coded
by Dirac, the answer should be "yes"!
Dirac has the capability of compressing high resolution files
for production, compression for broadcast content, and compression
for web 2.0 applications. Compression can be either lossless
or visually lossless. This is, of course, what is needed in the
production environment.
Dirac Pro was
created for high-end production applications. It uses a special
profile
of Dirac tools.
Alternatively Dirac can exploit lossy compression using long-GOP
formats for broadcasting and other distribution outlets. The
quality or compression efficiency is similar to that of AVC/H264
but without the encoding complexity or licence burden.
Most of the normal formats are built into Dirac as default settings.
For the more adventurous, most parameters can be varied simply
and effectively.
- Direct support of multiple picture formats
- 4K e-cinema through to QCIF
- Supports I-frame only up to long GOP structures
- Direct support of multiple chroma formats
e.g. 4.4.4/4.2.2/4.2.0
- Direct support of multiple bit depths
e.g. 8 bit to 16 bit
- Direct support of interlace via metadata
- Direct support of multiple frame rates from 23.97 fps to
60fps
- Definable pixel aspect ratios
- Definable "Clean Area" for inputs within larger
containers
- Definable signal ranges and offsets
- Multiple colour spaces with metadata to describe:
- Colour Primaries
- Colour Matrices
- Transfer Functions
- 32 bit frame numbers (more than 2 years at 60 fps) in both
I frame only and Long-GOP
- A choice from multiple wavelet filters (including filters
optimised for down-conversion)
- Definable wavelet depth
Are you paying out very large amounts of money for Codec license
fees? Are you in search of the ideal video compression format?
Do you find that one of your biggest challenges is the myriad
of proprietary media formats? Does the stringent and complex
licensing environment put you off making decisions? Do your customers
operate on a range of different platforms? It is hard to choose
the right compression system.
But there are many video compression systems, you may want to
know what is special about Dirac.
If you are the sort of person that hopes that your content has
a long lifetime, consider the upgrade policy of your existing
suppliers. Can you handle a format conversion on a regular basis?
Can you handle the lack of support for 'obsolescent' technologies?
If you cannot, then Dirac offers a long-term solution for you.
Because the source code for the software is available for operation
on a variety of platforms, you can have confidence that Dirac
can stand the test of time.
If you want quality, in your own specialist area, Dirac provides
a simple, but powerful range of options which can be selected
to fine tune the performance for your content.
If you want a cost effective solution, then the Open Source
licence means that you are a customer that has to considered
respectfully by your suppliers. You will have a choice of supplier,
so you can select one who offers a service which you need, not
which they want you to buy. |
