About VStation 2.x from FutureVideo
-----------------------------------
Hardware: FutureVideo Inc.
Software: Eric Cosky

    VStation is a linear (read: VCR) edit control system that works with a large
number (over 100) of consumer VCRs and camcorders, as well as RS-422 high
end equipment. The control software is available for the Mac, PC, and Amiga,
and the hardware is connected to the computer via RS-232. Developer information
is included with the package if you wish to adapt the system to work with other
platforms. The hardware is capable of controlling three VTRs at a time, but you
may connect fewer if desired. The AREXX port provides over 100 functions
and access to all relevant internal variables for easy integration into the
Amiga environment. There are LOTS of features. Some of them are:
    . multi event (unlimited number) EDLs with auto-assembly
    . Toaster framestore/cg/background control (per event).
    . Mix & Match different kinds of VTRs.
    . online point & click help.
    . park & preview/perform.
    . A-B roll using VTRs, Framestores, etc.
    . Two external GPIs, one internal that can trigger another program.
    . Optional SMPTE.
    . Frame accurate with RS-422 frame accurate VTRs.
    . Better control of a wider variety of low-end VTRs than anyone.
    . Tape logs, and much much more.
    . Supports PAL/SECAM/NTSC.

    Although FutureVideo has not had the best reputation in the Amiga community
for edit controllers in the past, this was entirely due to poor software on the
Amiga platform. The hardware itself has been refined for many years now, and the
FutureVideo Mark II edit controller has been very successful as a consumer product
for some time. The same technology has been incorporated into the Editlink 3300
controller (the VStation hardware) with many advances giving the 3300 all of the
functionality that the average video producer needs without bells and whistles.

    Believe it or not, the first Amiga controller software was actually ported
from a PC with a cross-compiler that basically made the Amiga look just like
a PC. Naturally, this didn't go over very well in the Amiga community. I wrote
the next version of the software intended for the Editlink line, and it was
functional, but definately a learning process. It lacked many features desired
by video professionals, and it was started back when AmigaOS 1.3 compatibility
was important. It did the job adequately for many people, but was no match for
AmiLink, TAO, and others.

    Version 2.x of the VStation software for the Amiga is a complete rewrite; the
only things left over from Version 1.x are _some_ of the low-level communication
routines that work fine the way they are. The rest however, is completely new and
is the result of a 9 month development cycle. The executable is ONE file that is
very easy to install. There are also some ARexx scripts to get you started. The
manual contains several tutorials about how to do different kinds of edits and
how to configure the hardware. There is free technical support available. But most
importantly, the program is very easy to use compared to other edit controllers.

    The program is currently geared towards Video Toaster users, but it will work
fine on any Amiga with at least 1 meg of ram and 2.04 OS.


Comments from the Author:
-------------------------
    I've been using Amigas since 1985. I've also been a videographer for almost
as long. I wrote this software out of my own personal needs and use it nearly
every day. I am determined to make this program the best linear editing package
available and I encourage suggestions. FutureVideo's hardware appears to be
the least expensive to manufacture by at least HALF because of it's simpler design,
but at the same time provides everything I need to edit videos properly. While
it doesn't yet provide more than three deck control, I feel that since everyone's
going non-linear anyway, the role of an edit controller will soon be to simply
automate the digitizing of material into the computer for multi-pass non-linear
editing which would only require one or two decks anyways.
    To deal with a video whose low-compression storage requirements exceed
online disk space, these videos will initially be edited in a high-compressed
format in order to maximize the amount of raw footage available on disk. When the
editing is finished, the only the material used in the final product will be
re-digitized (at low compression) so that disk space usage is optimized. If the
video still exceeds disk storage capacity, the system will put down as much as it
can onto tape and then re-digitize the material required for the next section.
Whew! Only the very high end of the non-linear systems do this today, but there's
no reason why it can't be done using the VStation software to control the tape
control aspect of the job. I've got a PAR and an AD516 and plan on doing just that
if someone else doesn't do it first.. after VStation 3.x, of course.

Things to know about the VStation Tour:
---------------------------------------

* Does not save projects.
* Does not allow AREXX results.
* Does not communicate with edit controller.
* Has an auto-demo mode with speed settings controlled via Icon Tooltypes.
  The tooltypes have been set to these values:
    DemoTimer=300    How many 10ths of a second to wait before entering
                demo mode.
    DemoPause=30    How long to wait between each demo command.
    AutoDemo=1      Allow it to enter automatic mode. If set to 0, then
                demo mode is effectively disabled and it will not
                engage demo mode until the F1 key is pressed.
* The F1 key will start the auto-demo mode.
* It will load the script file 'SetupVSDemo.vstation' via AREXX, so you
  need to be using it on a computer with sys:rexxc/rx available if you
  want it to prepare the demo EDL. It will work without it, but it will
  not be able to prepare the demo EDL unless it is there.
  The setup script will prepare 4 events, load some tapelogs, set some
  tape ids, and basically set it up so that it gives an ideas of how it
  appears when in actual use.
* The VCR tape speed is simulated for demonstration of the auto calc and
  use location. Only some of the transport controls have been implemented
  for this mode: Play, stop, rewind, forward, pause. The tape location flashes
  oddly in this demo, but not in the actual program.
* You can use almost every part of the program with the above limitations,
  including the help mode (help key). You can add/delete/clean/ripple events,
  change variables, set edit points, and see how the toaster is interfaced.

You will probably have to position the screen (by holding the left amiga
key and left mouse button while moving the mouse) in order to see everything.
Your monitor can be adjusted to make this unneccessary if so desired.

Besides the above notes, the program is pretty much the same thing as the
release version so this should give you a pretty good idea how the program
operates. Have fun, and call us at 1-800-346-5254 or
