L-SERVER
HD - Developed by Hollywood Studio Engineers
L-Server™, introduced in 2003
at NAB remains
a premiere open
architecure film and video conforming
system.
L-Server was developed
by Award
Winning Hollywood engineers from
major moption picture
studios. L-Server™
technologies have been tested in profesional
environments by demanding and
knowledgable studio professionals. L-Server
can capture and playback
uncompressed raw HDTV in real time directly from tape or HD Camera
source.
L-Server was
the first Open Source and Open Architecture Linux based HD server and
its lineage is impressive. L-SERVER has an option that will enable you
to wrap your
raw video with MXF in real-time.
L-Server™
simple editing functionality provides a
basic editing system that
enables you to view and edit clips or still video images, anywhere on
the time-line. The time-line editor enables you to extract,
update,
and replace a raw frame or series of raw frames.
HD-DDR
Deck
Control
L-Server™ has Serial RS232/422
control ports
with Sony protocol for external deck control. We have included software
algorithms that are within the deck control interface
and make adjustments for tape deck frame offset from requested to
landed frame position. This makes the capture system frame accurate
every time even on captures from multiple decks.
GAMMA
AND
CONTROL ADJUSTMENT
The operator has Gamma
controls using a built-in
flexible bezier curve window. Color adjustments are made using a color
curves panel.
NETWORK
CONNECTIVITY
Frames
can be accessed via network connection for
digital effects or computer graphics.
Share sequences with multiple computer systems cross platform with
Linux, Mac, Unix, PC/Win or other
graphics platforms using
standard NFS/SMB file system.
CONTROL
PANEL SOFTWARE
The operator can control
the DDR and/or remote tape deck from a
software control panel application giving you to the shot file system,
burn-in control, 2D color matrix, Gamma, time code, and burn-in
graticules
AUTOMATE
VIA SCRIPTING
The optional
command line
interface allows the operator to customize
the capture process with scripts to automate the steps of recording,
transfer, process or playback from the DDR to your production
environment and requirements.
MXF
Linux
Media Arts has been working
on MXF technology and systems since 2001 and continues to offer
consulting and design services on Linux based MXF. LMA was the first
company to first exhibite Linux  MXF
technology at NAB in 2003
and now offers MXF as an option on
L-SERVER, CINELERRA, and ENSANTRA.
Please
ask how we can
help you with your MXF consulting needs and on your system
deployment. MXF
is
an object subset of AAF and is on the verge of becoming an SMPTE
standard. MXF was designed for less complex (less vertically rich)
metadata applications, such as news editing and video streaming from
servers. Because of its
flatter metadata structure, it is better suited to be used as a
metadata
wrapper within a video signal or a TCP/IP stream. It offers performance
benefits over the more complex AAF file structure because of its
streamable
nature.
Material
eXchange
Format is an open file format targeted at the interchange of
audio-visual material with associated data and Metadata. It was
designed and implemented with the aim of improving file-based
interoperability between servers, workstations and other content
creation devices. These improvements will lead to improved workflows
and result in more efficient working than is possible with today’s
mixed and proprietary file formats.
Functionality
L-Server™ is
extremely functional and designed for ease of use in all conditions,
whether in
a studio broadcast environment or even in the field. Capture
video on the fly,
without a cumbersome set-up. Push a button and choose whatever
you
like to capture. Frames are seen indivudually
by the operator
and managed directly. Take your shots and and  drop
them into the
EDL in any order. Pull the shots out of a shot list youre
ready to play. Nothing could be simpler or more robust. We guarantee
it. The L-SERVER is designed so you can drop frames anywhere in the
timeline, one-by-one or by the bunch. Format mangement is easy,
too. Set the frame size and frame rate where you are working
in. Its easy to switch between any format, on the fly. The
L-Server is so robust, there will be no "hiccups" when switching
formats between 1080p, 1080i, and 720p.. Drag and drop clips from
the
shot list into the EDL window, fetch frames from online disk storage or
pull shots from a VTR then hit play to view the shots.
L-Server™
open architecture is plug-in ready. You can use provided
L-Server™ plug-ins and also build your own plug-ins for L-Server™
. The L-Server™ Software Development Kit (SDK) enables the
developer to build plug-ins, codecs, and special effects. These effects
can be dropped right on the L-Server™ video track timeline,
providing you the freedom to experiment in a live production
environment. The result is displayed in real time and can be
rendered in multiple supported file formats. Inserting specific codecs
enables the artist to edit all media wrapped within an MXF file.
FRAME
BASED VIDEO
We
capture
all
video on the L-Server™
as as
a sequence of stills
allowing quick video for playback, looping, Ping-Pong and
forward/reverse play, slow motion or fast play. The L-Server digital disk
recorder offers
High Definition 720p, 1080i and 1080 24psf formats with either 8-bit or
10-bit resolution in uncompressed RGB or YUV color space. The L-Server™™ system is a uncompressed digital disk
recorder designed specifically for video and graphics
professionals requiring a powerful and tested recording and playback
system. The L-Server™
is a new design which gives studios more control over shot management,
capture and network transfer capabilities. The L-Server™ can replace broadcasting and video
post-production video tape recorder. Easily access and play clips
or frames, thus, offering you many advantages over tape based
systems. Video is captured sequentially as still
images at the rate of one file per frame. Instantly access video for
playback, looping, Ping-Pong, forward/reverse play, slow motion or fast
play. Frame based file systems allow the user direct access
to any frame in the sequence for compositing, editing, digital
intermediate, networking, or animation. Its a direct process
to extract, update or replace any frame or frame series
from a sequence. In other words, any frame can be identifed
and manipulated without compromising the sequence.
