Note: The calculation routines have not yet been optimized. Therefore, the
automatic ripple calculations may make the program slow to respond
to your keystrokes, especially when typing in the source in or out
time codes. You may still type quickly; the program will catch up
to you.
Very Brief Instructions:
Start the program by selecting the EDLP icon. The EDLP screen will
appear. The top grey line is the warning line; red warning messages will
appear there. The second grey line is the prompt line; green prompting
messages will appear there to tell you what the program is expecting.
Below that is where the title will appear. It is blank now, because you
have not yet entered a title. The title will appear in purple letters, and
will always be centered.
Just below the title area are the column headings; these are in yellow.
The columns are described as follows:
> Event number. A three digit number from 0 to 999.
> Reel Number. Up to six characters identifying the source reel.
> Trac. Specifies whether the event refers to video, audio channel 1,
audio channel 2, or some combination of the three. This column is
automatically formatted so that no matter in what order you enter
the information, it will appear as V/An, where n is the audio track
number if required. This column is also automatically always in
upper case.
> Type. This refers to the type of edit; either Cut, Dissolve or Wipe.
Only the first letter is required. If the event is a wipe, you may
add three digits following the W to specify which wipe.
> TR. This is the transition rate in frames for a dissolve or a wipe.
> Source In. This is the time code for the start of the take.
> Source Out. This is the time code for the end of the take.
> Record In and Out are calculated by the program. You cannot move the
cursor into these columns.
The list itself appears in grey when you first start the program. This
is because any event that has not been assigned a track appears in grey.
Near the bottom of the screen is the grey track record line. The record
in times for all three tracks for the current cursor position are always
displayed there. This will come in very handy when you are doing split
edits.
Below the track record line the current contents of the "paste" buffer
are displayed in dark red. Anytime you copy or delete an event, it will
appear here. The contents of the paste buffer may be inserted into the
list as many times as needed.
The menu commands are as follows:
> New. Clears the entire list.
> Load. Loads a list from the disk. This version allows only one file,
so you are not prompted for a filename.
> Save. Saves the list onto the disk.
> Print. Prints the list. Pages are numbered automatically. The program
will not separate a comment from its event. Future versions will also
print the date.
> Xfer. Allows transfer of list to and from an external device via the
serial port.
> Quit. Same as selecting the close gadget in the upper left corner of
the window.
> Non-Drop or Drop frame. Selecting one reformats the entire list. Drop
frame is indicated by a period instead of a colon between the seconds
and frames in every time code.
> Skip or Non-Skip Record. Selecting Skip causes the record in of each
event to be one frame later than the record out of the previous one.
Selecting either reformats the entire list.
> Insert Comment. Creates a comment line preceeded by an asterisk for the
event under the cursor.
> Delete Comment. Deletes the comment for the event under the cursor. The
cursor may be on the comment or the event itself.
> Delete Event. Deletes the event, including comment. The deleted event
(including comment) is stored in the paste buffer.
> Get Event. Copies the event (including comment) into the paste buffer.
> Insert Event. Inserts the contents of the paste buffer into the list
at the cursor position. The list is immediately renumbered and rippled.
> Change Title. Selecting this will cause the title gadget to appear.
Select the gadget with the left mouse button before typing or changing
the title (WB version 1.1 only). Close the gadget by pressing RETURN
or pressing the left mouse button with the pointer outside of the
title gadget.
> Change Record Start. This allows you to change the initial record start
time. The default is 00:00:00:01. Selecting this command will cause
the record start gadget to appear just under the Record In column
heading. Select this gadget with the left mouse button before typing
or changing the record start time (WB version 1.1 only). Use the DEL
key to delete existing digits. Press RETURN to end. If the time code
is not valid, you will get an error message and be asked to re-enter
the data. Select the gadget again before doing so (WB version 1.1
only). (This whole procedure will improved in a future version).
The scroll gadget on the right side of the screen shows how much of
the list is being displayed. If the list is longer than can be displayed
on one screen, you may slide the scroll gadget to move through the list.
You may also "click" just above or below the scroll knob to move one
page up or down.
Now that the options are out of the way, you can just start typing in the
information. If you press an invalid key, the screen will flash and an
error message will appear (future versions will have sound). If you enter
an invalid time code (e.g. 00:01:00.00 in drop-frame mode), you will also
get an error message. If there is an error during a ripple calculation
(e.g. mismatched split edits), the error message will tell you which event
had the error.
Use the arrow keys to move the cursor around on the screen. A few things
to note are:
> Pressing RETURN or TAB advances the cursor to the next column. Pressing
ENTER on the numeric keypad moves the cursor to the first character on
the next line.
> Entering the last digit of the source out does not advance the cursor
to the next column as you might expect. This is so that the ripple can
take place and any errors detected. After entering in the last character
for the line just press RETURN, TAB or ENTER to advance to the next line.
> The ALT and CTRL keys are treated like the SHIFT key, except for CTRL-P,
which grabs the character just above it from the previous event (except
for comments).
> The ESC key restores the current line to the condition it was in before
the cursor moved onto it.
That's about it. If you have any comments or suggestions (and I know
you will), please forward them to me on Compuserve using PPN #73267,3361,
or call or write to me directly. Thank you!
