Pinnacle Systems is attempting to leverage its HD
and networking heritage and expertise with the
introduction of a HD option for its own Liquid
editing application. The Liquid editing
application drives a family of products that
includes the software-based Liquid Edition, Liquid silver for
MPEG-2 post editing, Liquid chrome for real-time post
settings and Liquid blue for multi-format broadcast
environments.
Pinnacle’s HD options for Liquid is essentially softwarebased
in nature. In fact the ability to playback HD in the Liquid
timeline will just be a simple software upgrade for existing
Liquid customers – only those looking for HD-SDI I/O will need
additional hardware. A two-tiered approach to HD will enable
the HD option for Liquid to handle both professional HD
formats as well as prosumer formats, most notably HDV.
In fact, Pinnacle is betting that HDV will quickly emerge as
both a popular prosumer format and a professional format for
certain applications. Purists may argue about whether HDV is
truly HD or not, but there is no question that it is much better
looking than DV and we have already seen the success of DV
for these applications. HDV is MPEG-2 MP@HL (Main Profile @
High Level) which translates to a 4:2:0 high definition format.
For people doing professional work like trade shows, religious
programming, the high-end of wedding videography, and
even some broadcast news outlets, the combination of lowcost
and high quality will be difficult to ignore.
PCI Express Standard
Pinnacle is known for the use of off-the-shelf technology to
deliver professional, prosumer and consumer video editing
tools. The current version of Pinnacle’s Liquid Edition delivers
real-time video editing effects capability harnessing only the
PC’s onboard CPU and GPU (graphics processor).
Pinnacle has therefore allied itself with some heavy hitters to
extend this architecture to support real-time editing, effects and
compositing in HD. Earlier this year the company teamed up
with Intel and ATI during the keynote of the Intel Developers
Conference to demonstrate the use of the enhanced data
transfer capabilities offered by the new PCI Express standard.
PCI Express will enable Pinnacle to use off-the-shelf
technologies to extend real-time HD editing and effects.
Companies like ATI have already committed to incorporating
PCI Express interconnects directly into their graphics chips,
meaning accelerated high bandwidth, symmetrical data transfer
should shortly be available at mainstream prices.
Pinnacle Liquid HD with PCI Express
will allow HD data rates out
of the box
