MediaEditor Version 2.2 Documentation 4/20/91
MediaEditor 2.2 sports the new Workbench 2.0 look. It uses a
high-resolution, four color interlace mode with 3-D graphics. MediaEditor
requires at least 750K of free RAM,400K of which must be CHIP RAM.
MediaEditor can still run under Workbench 1.3 on Amiga 500 equipped with
a 1/2 meg AGNUS graphics CHIP and 1/2 meg of FAST RAM for a total of 1Meg.
The menus described in the MediaEditor software manual have been
removed. Gadget-bars are provided instead . A gadget-bar is a
horizontal row of gadgets that provides the same function as menus but with
quicker to access. MediaEditor is still divided into four sections:
Configuration Files
Device Files
Code Files
Edit Decision List
Each section uses the same gadget-bar located at the bottom of the
MediaEditor screen in each of the four program sections. A representation
of the gadget-bar is shown below:
+-------------------------------------------------------------------+
| +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ |
| | A | | B | | C | | D | | E | | F | | G | | H | | I | | J | | K | |
| +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ +---+ |
+-------------------------------------------------------------------+
A list of gadget-bar gadgets and their corresponding functions is shown
below. The function descriptions are similar to those for menu items
described in the MediaEditor software manual for earlier versions of
MediaEditor. References to these menu item descriptions are made throughout
the text.
+---+
| A | This gadget loads a file. The type of file loaded depends on
+---+ which section of MediaEditor you are in. If you are in the
Configuration Files section, the gadget acts like the "Load" item
in the "Project" menu described in the manual. It brings up a requestor
to load ".config" files. Use this gadget in other MediaEditor sections
to load ".dev", ".code" and ".mb" mediabase files.
+---+
| B | This gadget brings up a file requester to save a file. The type
+---+ of file is saved depends on which section of MediaEditor you are
currently in. If you are in the Configuration Files section, the
gadget acts like the "Save As..." item in the "Project" menu described in
the manual. Use the gadget in other sections of MediaEditor to save ".dev",
".code" and ".mb" mediabase files.
+---+
| C | This gadget acts just like the "B" gadget above except that it
+---+ doesn't bring up the file requester before saving. It saves the
file with what ever name was last chosen.
+---+
| D | This gadget brings up a file requester to delete a file. The type
+---+ of file deleted depends on which section of MediaEditor you are
in. Use this gadget to delete ".config", ".code", ".dev" and ".mb"
files.
+---+
| E | This gadget changes to the Configuration Files section of
+---+ MediaEditor. It acts like the "Config" menu item of the
"Work On..." menu as described in the manual.

+---+ into MediaEditor. It acts like the "MediaController" item
of the "Work On..." menu as described in the manual.
+---+
| J | This gadget runs a MediaController using the configuration file
+---+ selected in the Edit Decision List as the recorder device. This
gadget acts like the "Recorder" sub-item in the "MediaController"
menu item found in the "Work On..." menu of the Edit Decision List section.
A Recorder configuration file must be selected in the Edit Decision List
section of MediaEditor in order to make this gadget active.
+---+
| K | This gadget quits MediaEditor and returns back to the Workbench
+---+ screen. This gadget acts like the "Quit" item of the "Project" menu
described in the manual.
POP-UP MENUS
---------------------------------------------------------------------------
The configuration and device files sections make use of a new feature of
MediaEditor 2.2, pop-up menus. Pop-up menus are activated to select
parameters and associated values for data display lines like the one
shown below:
+--------+ +---------------------------------------------------------+

| +-----------------------+ +-+ |
+-----------------------------------+
Text and values can be entered directly into the pop-up menu "TextEntry"
gadget. Entered data is copied into the data display gadget described
above.
The gadgets marked "Selection1,2,3,4" list 4 of the
acceptable choices for the text-entry gadget. By clicking on any of
these gadgets, you copy the text displayed there into the pop-up menu's
text-entry gadget.
The gadgets marked "B" and "C" allow you to scroll up and down the list of
acceptable values one at a time. Scrolling around like this can be a
little slow, so the scroll gadget, marked "D" is used to speed things up.
After a parameter or value has been selected from the list, click on the
gadget marked "A" to close the pop-up menu and coppy the contents of the
text-entry gadget in the pop-up menu into the text-entry gadget on the
MediaEditor screen.
CONFIGURATION FILES
---------------------------------------------------------------------------
The Configuration Files section screen contains 15 rows, each with 3
gadgets. Each row defines a configuration file paramenter and its
associated value.
The left-most arrow gadget of a data display line activates the pop-up
menu as described above. The value selected from a pop-up menu is used
as a configuration file parameter and is copied into the middle display
line gadget, the text-entry gadget.
The text-entry gadget is used to select and display a configuration file
parameter. As described above, you can activate a pop-up menu to select an
appropriate parameter for this gadget.
The right-most gadget is a text entry and display gadget that allows the
entry of the value for the associated parameter displayed in the gadget in
the middle of the line.
DEVICE FILES
---------------------------------------------------------------------------
The Device Files section screen contains 2 columns of 17
rows, each with 3 gadgets. Each row defines a device file paramenter
and its associated value. There are now 2 pages of parameters,
each containing 34 entries, for a total of 68 possible device file
parameters.
The left-most arrow gadget in each row activates the pop-up menu as
described above. The value selected from a pop-up menu is used as a
device file parameter and copied into the text-entry gadget in the middle
of the screen line.
The middle gadget is a text-entry gadget for selecting a device file
parameter. As described above, you can use a pop-up menu for selecting an
appropriate value for this gadget.
The third, right-most gadget is a text entry gadget that allows the entry
of the value for the associated parameter defined in the middle gadget of
the same row.
To go to the first page of device file parameters click on the gadget at

CODE FILES
---------------------------------------------------------------------------
The Code Files section has a second gadget-bar. It is loacted at the top
of the screen. Gadgets in this area are specific to the code file
section of the screen. They allow the user to select operations to be
performed on screen code gadgets.
The code gadgets, 128 in total, are displayed throughout the screen.
Like earlier versions of MediaEditor, each code gadget has an associated
name displayed in the center of the gadget. If the name is displayed
in orange with a black outline, then there is no code currently stored for
the gadget. If it is displayed in white with a black outline, then there
is currently a code stored for the gadget.
The following is a representation of the gadget-bar at the top of the code
file screen:

OTHER TOPICS
---------------------------------------------------------------------------
MediaEditor's video editing logic has been refined. You may have to reset
your PlayOffset0, RecordStartOffset and RecordStopOffset paramenters to
account for increases in execution speed and logic changes. Refer to the
MediaEditor software manual and the rest of this Read-Me file for more
information about these and other parameters.
MediaEditor 2.2 uses a new version of the "mediaphile.library", "AudioSeg",
"CtrllSeg" and "FVSeg". Therefore, hard drive users must re-install the
the contents of the MediaPhile Devs disk.
CHANGES AS OF MEDIAEDITOR VERSION 2.11
----------------------------------------------------------------------------
The MeMediaPhile software now supports the Future Video Controller as
as well as MediaPhile controllers. Feel free to mix both types of
controllers in the same system. They can be used simultaneously. Refer to
the Future Video Controller section of this ReadMe file for more information.
The MediaPhile control system does not operate correctly when using VTR's
operating in any other speed other than standard play(SP). All device
timing parameters determined by Interactive MicroSystems have been set
from test run with video tape playing at SP speed.
If you are using SMPTE time code, it is strongly suggested that the time code
be recorded only on a video tape's left LINEAR audio track at SP speed.
Recording SMPTE time code on either the hi-fi audio track or at a faster
speed results in a noisy signal.
1) MediaEditor has been altered to work with the new detachable
MediaController. You can run several copies of MediaController at one time
from MediaEditor, and continue to make alterations to your configuration,
device, code and edit-list information.
For example, in the Edit Decision List program you can have a
MediaController up and running for both the Player and Recorder devices at
the same time. You can use the Player MediaController to find the IN and
OUT points of your edits, click back in the edit list window and enter the
edit points.
You must close all of theMediaController's opened on the screen before
selecting menu items from MediaEditor's menus. IF ALL THE OPENED
MEDIACONTROLLERS ARE NOT CLOSED BEFORE SELECTING MENU ITEMS, MEDIAEDITOR
WILL CRASH.
2) The device parameter "PollInterval" serves a dual purpose when using
Sony Control-L devices. This parameter still specifies how often we read
in tape position information as for other devices, but unlike other devices
it also determines how often the tape position counter is refreshed in
MediaController.
If the Control-L device will be used as a slave recorder values ranging
from .05sec to .99sec are suggested. Higher "PollInterval" times free
up processing time for the other devices. If you wish to use the Control-L
device as the master player use values of .05 and lower.
If you are using more than one Control-L device at a time, the lowest
"PollInterval" value takes precidence over the others. This means that if
you have a recorder device with a "PollInterval" parameter of .2sec and a
player device with a value of.05sec, both the Player and Recorder counters
will be refreshed every .05 seconds. Note that using larger values frees
more processing time but decreases the accuracy of reading in frame
positions.
3) Several new parameters have been added to the Device description.
Some of these parameters are to be entered in only if you are using the
MP2.0S Serial controller along with a Sony Control-L compatible video deck.
The MediaPhile system also makes use of our propreitary Frame-Resolution
Control-L software. Sony developed Control-L to be accurate to the second,
but using the new Frame-Resolution software, Control-L can now be accurate
to the frame. Like other formats, the accuracy does also depend on the
device. The Sony CCD V99 is usually accurate to two frames where-as the CCD
V9 is can be off by as much as 7 frames. But any way you look at 7 frames
is still better than 30 frames (or one second). The following is a list of
the new parameters that are needed by the new Frame-Resolution software.
---------------------------------------------------------------------------
PAUSEADJUST:
This parameter describes the number of frames that pass between a
Control-L play message and a Control-L pause message. To adjust this
parameter, run and synch MediaController to a video tape with a window dub
time code. Place the deck into play mode and leave it there for a few
seconds. Put the deck back into pause mode. The difference between
the frame position shown in the tape window dub and the position displayed
in MediaController is the "PauseAdjust" value. In the Device section of
MediaEditor enter:
PauseAdjust = 'xxxx'
where 'xxxx' is the value taken from your test.
Re-run MediaController after entering this parameter and perform the
test a few more times, adding up the values and re-adjusting the
"PauseAdjust" value in the Device description accordingly.
Here is how I determined the "PauseAdjust" parameter for my CCD V99.
First, I created a video tape with time code showing
HOURS:MINUTES:SECONDS:FRAMES in a window-dub area in the lower right of the
screen. Next, I put the deck in pause on an easy-to find point, and
pressed the counter reset button on the camcorder. At this point my
window-dub displayed 0:01:00:00 and my MediaController position displayed
0:00:00:00. I then put the deck into play mode for a few seconds and
pressed pause again. At this point my window dub displayed 0:01:03:12 and
my MediaController position read 0:00:03:06. There was a 6 frame
difference between the two. Back in MediaEditor's Device section I entered
"PauseAdjust = 6". I ran the test again a few more times and found that
the difference was usually 1 frame so I added 1 to the "PauseAdjust"
value making it read "PauseAdjust = 7".
---------------------------------------------------------------------------
CUESPEED:
NOTE: THIS ATTRIBUTE IS RESERVED FOR FUTURE USE. IT IS NOT CURRENTLY IN USE.
This parameter describes how many times faster the tape moves in cue mode
as compared to play mode. To adjust the paramter find the how much time
elapsed when cueing the tape for 30 seconds. Change
this elapsed time to seconds using this formula:
time = seconds+(minutes*60)
Take this value and divide it by 30 and enter into the Device list as:
CueSpeed = 'xxxx'
where 'xxxx' is the value discovered above.
---------------------------------------------------------------------------
REVIEWSPEED:
NOTE: THIS ATTRIBUTE IS RESERVED FOR FUTURE USE. IT IS NOT CURRENTLY IN USE.
This parameter is exactly like CueSpeed except that it describes the factor
between review mode and play mode. You can find its value using the same
directions as above but using review mode instead of cue mode.
___________________________________________________________________________
4) The MediaPhile device control system now supports SMPTE Time Code as a
means of re-synching internal tape counters. To support SMPTE Time Code,
three new parameters have been created:
---------------------------------------------------------------------------
SMPTEPort:
This parameter describes which device port, Serial or Parallel, the
SMPTE Time Code is going in to, with each port supporting two lines input
lines. Correct values for SMPTEPort are:
SMPTEPort = PAR1
SMPTEPort = PAR2
SMPTEPort = SER1
SMPTEPort = SER2
SMPTEPort = NONE
The hardware manuals incorrectly called this parameter 'SMPTE' and not
'SMPTEPORT'. Please make a note of the change.
If you are using SMPTE, you should increase the device pre-roll parameter
to at least 450 frames (15 seconds) to allow additional time for the SMPTE
time code to be read and used to synchronize the device tape position data.
---------------------------------------------------------------------------
SMPTEADJUST:
This parameter describes an adjustment, measured in frames, added to
the SMPTE Time Code read from the device to compensate for the time required
to process the time code data. If this parameter is not set in your device
file, a default value of three frames is added to the time code value read
from the tape.
If you find that the SMPTE Time Code read from the device is less
than the correct value determined from a time code window dub on a
test tape, increase the SMPTEADJUST parameter by entering the following
line into your device file,
SMPTEAdjust = n ,
where "n" is the number of frames to be added to the time code value
read from the tape. Make "n" greater than or equal to the default value of
3. If the SMPTE Time Code read from the device is greater than the actual
value, enter a value between 0 and 2 for SMPTEADJUST.
Use the test described below to determine the correct SMPTEADJUST
value. The test assumes that the device interface hardware is correctly
connected and that the SMPTEPORT parameter in the device configuration file
has been set prpoperly.
1) Run the TCGen program and use it to generate a tape with SMPTE Time Code
recorded on at least one audio track, and the TCGen screen recorded in the
video signal. Refer to TCGen's documentation for further instructions.
2) Using MediaController place the deck into play-pause mode and set the
counter to a value of 999999. After doing this place the deck in play
mode and wait five seconds. After waiting, press the Time Code SYNCH
gadget (the clock) in the lower right corner of MediaController.
The MediaController tape position display should reset itself to the
SMPTE Time Code recorded on the tape. After the display has been reset,
place the deck back into play-pause mode and record the difference
between MediaController's counter and the TCGen window tape position
display recorded in the video signal. This window dub time code is in
exact agreeement with the time code recorded on the audio track.
3) Repeat step 2 a few times and record the average of the differences.
4) Enter MediaEditor's Device file section and enter:
SMPTEAdjust = 'n' ,
where 'n' is the average of the differences determined by step 3.
---------------------------------------------------------------------------
AVDELAY:
This device parameter is set equal to the time between entering play
mode and the actual output of audio and video from the device output jacks.
For example, the Panasonic AG-1830 SVHS deck requires 7 seconds of playing
time before it outputs audio and video. For this deck enter
AVDelay = 7 ,
in the device file. If the AVDelay parameter is not set in the device file,
a default of five seconds is used.
---------------------------------------------------------------------------
FRAMESPERSEC:
This device parameter is set equal to the number of video frames the
device will play back in one second. For NTSC video devices this number
should be set equal to 30 by entering:
FramesPerSec = 30
For PAL video devices this number should be set equal to 25 by entering:
FramesPerSec = 25
If this device parameter is left out of the MediaPhile "device" file, the
system will automatically calculate the parameter according to the Amiga's
video clock rate. A value of 25 frames per second is used for the PAL
version of the Amiga Computer. A default value of 30 frames per second is
used for NTSC Amiga computers.
INSRECPSECMD2 :
The InsRecPseCmd definition in the MediaEditor manual has been changed and
a second parameter has been added. The InsRecPseCmd now specifies the first
command issued to the record deck upon reaching the recorder IN point.
InsRecPseCmd2 specifies the second command sent to the record deck. The
default values are:
InsRecPseCmd = PAUSE
InsRecPseCmd2 = RECORD
For the JVC 10000 and 6600, use
InsRecPseCmd = PAUSE
InsRecPseCmd2 = NOP
if the deck has been manually placed in insert mode.
_________________________________________________________________________
_________________________________________________________________________
FUTURE VIDEO CONTROLLER:
The Future Video Controller is driven by a MediaPhile shareable library
"Seg" called "FVSeg" located in the "libs:MPSegs" directory. FVSeg is very
similar to the Sony Control-L tape position data input Seg. However, FVSeg
also allows for device command output and SMPTE time code input through the
serial port from Furture Vdideo controllers. FVSeg supports two video decks
called SERFVP for the Future Video player deck and SERFVR for the Future
Video recorder. The SER pre-fix indicates that the controller is connected
to the serial port.
To create the player device configuration file for a video deck that is to
take tape position information into the computer from the Future Video
controller, enter the following line into the device configuration file:
CountPort = SERFVP.
To create the recorder configuration file, enter the following line
into the device configuration file:
CountPort = SERFVR.
If commands are to be sent to the player deck through the Future Video
Controller enter
CmdPort = SERFVP
into the player device configuration file. For the recorder deck substitute
SERFVR above.
Device commands need not be sent to the player and recorder decks through
the Future Video controller. Tape position information can be brought into
the computer throught the Future Video controller and commands sent to a
deck through the MediaPhile infrared controller by entering
CmdPort = AudioLeft.
Tape position information can also be brought in through a MediaPhile
controller while commands are sent through a Future Video controller.
To create a device configuration file to take SMPTE time code from the
player deck into the computer from the Future Video controller enter the
following line into the device configuration file:
SmptePort = SERFVP.
Substitute SERFVR for the recorder deck.
Of course you can also bring the time code data into the computer through
a MediaPhile controller. For example, enter
SmptePort = PAR1
to bring time code data in through channel 1 in the MediaPhile MP2.0P unit.
Control track tape position can be brought into the computer through the
Future Video controller at the same time by setting the CountPort equal
to the Future Video player or recorder port.
The following device configuration file instructs MediaPhile software to
take tape position information from the Future Video controller, send
device commands out through the MP2.0A controller connected to the left
audio port and read SMPTE time code from the MP2.0P controller.
countport = SERFVP
cmdport = AudioLeft
smpteport = PAR1
Taking tape position information into the computer from both the Future
Video player and recorder units can lead to innacuracies that come from the
inability to read both counter ports simultaneously. If Future Video counter
ports are specified for both decks, the time delay in switching from one
input to the other can lead to IN/OUT point tape positions in error by
several seconds. To prevent this from happening set the recorder deck
"countport" to a MediaPhile controller port or to NONE. It is also possible
to adjust the recorder's "RecordStartOffset" and "RecordStopOffset" device
parameters to account for the time delay in switching. In most cases the
record offsets will have to be increased by more than 30 frames.
The device files included on the MediaPhile_Devs: disk with your order were
set for configurations where commands are sent to both the recorder and
player decks through the Future Video controller, but counter
information is read only from the player deck. The recorder deck count port
parameter for the recorder is set to NONE. The "RecordStartOffset" and
"RecordStopOffset" device parameters have to be adjusted for configurations
where commands are sent to one VTR through the Future Video controller
while the other is controlled from a MediaPhile infrared controller.
New Device File parameters have been created for use with the Future Video
controller. The following is a table listing each new parameter and its
functional description.
POSITIONRESOLUTION :
This parameter determines the highest resolution tape position data field
read from the Future Video controller by MediaPhile software.
Its acceptable values are:
PositionResolution = FRAMES
PositionResolution = SECONDS
PositionResolution = FIELDS
This parameter defaults to FRAMES if it is not entered into the device file.
If "positionresolution = FRAMES" the FVSeg will depend on the Future Video
controller to provide tape position information good to the frame whenever
play or pause modes are entered from any other mode. FVSeg will use this
tape position information to try to remove tape slippage. As the Future
Video manual mentions, not all decks provide good frame information.
Sony Control-L devices connected to Future Video do not provide any
frame information at all. Other devices, like the Panasonic 1830 provide
innacruate tape position information in the frames data field. At this time,
only the Panasonic AG-1960 is known to provide tape position information
accurate to the frame without being connected to Future Video's SMPTE input
port.
The easiest way to determine whether or not your device provides tape
position information good to the frame is proceed as follows:
1) Create a tape with a video time code window dub with the MediaPhile
TCgen program or use on from your library of tapes.
1) Set the player device configuration file CountPort parameter to SERFVP
and the recorder parameter to SERFVR.
2) Enter device file section of MediaEditor and add or change the following
parameter:
PositionResolution = FRAMES
3) Load MediaController through MediaEditor's "Work On" menu and put the
deck in play-pause mode.
4) Change MediaController's tape counter so that it matches the value
recorded in the tape's window dub.
5) Put the deck in play mode for about five seconds and then put it back
into pause.
6) Record the difference between what is displayed on the window dub and
MediaController's tape counter.
7) Repeat steps 5 and 6 four or more times and calculate the average of the
differences between MediaControllers tape position display and the tape
window dub time code display.
If the recorded differences vary greatly from one test to the other,
i.e. 3 frames one test and 10 the next , or if the average difference
between the MediaController and tape time code displays is greater than
three frames, then the POSITIONRESOLUTION parameter should be set to SECONDS.
The PAUSEADJUST parameter should be set to the value of the average of the
differences. For example, if the average of the differneces recorded from
the test above is equal to 7 then you would enter the following line to
your device configuration file:
PauseAdjust = 7.
More information about the PauseAjust parameter is given above..
MAXPRIORITY :
This value describes the priority that a MediaPhile device gets whenever a
search operation is performed on it. This parameter's acceptable values
range from 0 to 128 and defaults to a value of 128. For maximum priority
enter the line
MaxPriority = 128
into the MediaPhile device file for your device.
A high priority allows a vide deck to receive more processing time than
other devices when a the tape is searched. Do not set this parameter for
devices controlled through MediaPhile controllers.
FVSeg uses priorities when a FindVTRFrame function is called. This function
searches for a particular tape position. Because CUE and REVIEW video deck
commands must be sent out continuously at a high rate, a high priority must
be given to the deck searched. Programs cannot send device commands or
recieve tape position information from other devices until the search is
concluded.
MINPRIORITY :
This value describes the priority a MediaPhile device gets whenever it
is assigned its lowest possible priority so that a search can be conducted
on another device. This parameter's acceptable values range from 0 to
128 and defaults to a value of 0. To set the parameter to its default value,
enter
MinPriority = 0
in the device file.
NORMALPRIORITY :
This value determines the priority a MediaPhile device gets during normal
operation. This parameter's acceptable values range from 0 to 128 and
defaults to a value of 0 when no value is entered. To set the parameter to its default value,
enter
NormalPriority = 0
into the device file.
Other Future Video Notes:
You should make certain that any VTR that is controlled by the FVSeg is
completely rewound and that its counter has bean reset to 0 before doing
any editing. Failure to do so can cause an edit to be off as much as 1
second. The AG-1960 deck gives inaccurate tape position information when
negative tape position times are displayed.
Use no stops mode for editing with Panasonic AG-1960 and AG-1830 decks.
These decks experience a high degree of tape slippage when run in fast
forward and rewind. Editing with SMPTE time code can correct for the tape
slippage and allow editing with fast forward and rewind.
Using MediaPhile Devices Whose Count Ports Are Set To PAR2:
If you have a printer connected to your parallel port, you must make certian
that you do not load a MediaPhile device whose count port is set to "PAR2".
Doing so, will cause the system to crash. To remedy this, disconnect any
printer connected to your parallel port.

USING THE MEDIAPHILE DEVICE CONTROL SYSTEM WITH THE SONY EVO-720 8mm deck:
The MediaPhile System now works with the EVO-720 8mm dual deck memo writer.
The EVO-720 player and recorder deck configuration files must be set to
take tape position counts from the MOUSEX or MOUSEY count ports on the
MediaPhile 2.0M contrfoller. You can define the EVO-720 recorder count
port as MOUSEX by changing the "CountPort" line in your config file with
MediaEditor so that it reads:
CountPort = MouseX
You can define the player count port as MOUSEY by changing the "CountPort"
line so that it reads:
CountPort = MouseY
The EVO-720 does not have an infrared reciever. Instead, the commands are
sent to the deck through the MP2.0S controller SER1 modular telephone plug.
The EVO-720 actually has two decks, a player and a recorder. To control
the player change the "CmdPort" line in your config file so that it reads:
CmdPort=EVOP
Set the recorder configuration file command port by changing the
"CmdPort" line so that it reads:
CmdPort=EVOR
There are two pre-made config files for the EVO-720 on your
MediaPhile_Devs: disk. One is for the player deck and the other for the
recorder. These configuration files are located in the
"Devs:Media/Configs/VTR" directory. We suggest that you use these two
files instead of trying to make your own. The name of the EVO-720's
player config file is:
SONY.720.EVOP.Y.EVO.config
The name of the EVO-720's recorder config file is:
SONY.720.EVOR.X.EVO.config
There are certain limitations when using the EVO-720 with the MediaPhile
Device Control system:
1. The EVO-720's recorder can not be used as a player device. If you wish
to use the EVO-720's recorder, You can only use the EVO-720's recorder
as a MediaPhile recorder device.
2. You can not perform Find Frame operations on the EVO-720's recorder.
Doing so will put the EVO-720 in edit-record mode.
3. The EVO-720's recorder can only edit in assemble mode. You can not
use MediaProcessor's automatic insert edit mode with the EVO-720's
recorder.
4. The EVO-720's player ignores the record command. This command is
only be understood by the deck's recorder.
