Using the ACE 10 Computerized Editing System
The default configuration of
the EVL video editing suite is BETACAM A/B Roll.
Major changes in editing configurations should be addressed to editroom@evl.uic.edu
On-line help can be obtained
by pressing HELP located on the dedicated ACE10 keyboard above the data
entry keypad.
Prepare:
- Reset ACE10 for a new edit:
Make sure the ACE10 is reset for a new edit; any previous hardware configuration
and/or edit decision list (EDL) is erased. To reset the controller:
- Go to the INIT menu
(the INIT key is in the upper left next to the logo on the control unit)
- Select USER1 (EVLDEFAULT)
using the 'soft keys' at the top of the control unit. This will load the
default hardware configuration for betacam A/B roll editing. The 8 'soft
keys' correspond to the 8 rectangular menu boxes located at the bottom
of the status monitor.
- Select SESSION RESET
and then CONFIRM. This will clear the previous EDL.
- To enable the ACE 10 to control
the JVC Switcher hit the * + 0 key on the switcher numeric control pad.
Cuts Editing:
A CUT is a zero duration transition
and the foundation of editing.
- Select the recorder - R
(transition and effects keypad)
- Use the transport control VAR
to find position of the recorder in point*
- Hit IN to set the record
entry/in point
- Select CUT (transition
and effects keypad)
- Select the source by hitting A,
B or Aux (depending on where your source is).
- Use the transport control VAR
to position of the source in point (this is not relevant to using AUX as source,
since it is the input from Sirius)*
- Hit IN to set the source
entry/in point
- Use the transport control VAR
to find position of source out point* NOTE: an out point is not necessary
to perform an edit. An open-ended edit can be made terminated by hitting STOP
during the edit; time code values at the 'stop' point will be automatically
loaded as the recorder and source deck out points and as the next edit's in
points.
- Hit OUT to set the source
exit/out point
- To preview the edit hit PREVIEW
- To perform the edit hit PREVIEW
and EDIT simultaneously
- To review the edit hit REVIEW
* In and out points can also be
entered using the data entry keypad. Time code value digits should be separated
by a colon or semicolon (1:20:10 = one minute, 20 seconds, 10 frames). A keypad
value will over ride tape position when hitting IN or OUT.
Once the edit has been performed,
the ACE10 will automatically advance to the next edit, move the completed edit
data into the EDL, and load the previous edit's out points as the subsequent
in points.
