The Pre-Post-Record [PPR] position is unique to Cantar, it al-
lows three important functions: pre-record buffer activation,
metadata entering/editing, and last take erasure.
Pre-record buffer
While the [MainSelector] is on PPR, the pre-record buffer
stores the audio in a First-In/First-Out (FIFO) buffer memory
and dumps them to the HD as soon as REC is activated.
The '•rec' icon blinks under the disk(s) selected for record-
ing. Once the buffer is full, up to 13 sec. @ 48kHz, it starts
discarding the First-In audio, the middle platter of the 'three-
platter' icon disappears; this is a way to verify the selected
buffer length (AUDIO/TC.08 ‘PreRec Dur’, p.31).
Pre-Rec metadata entry: 'NEXT take'
While in PPR, enter/edit the scene ID, take #, commments,
track-names and Audio-Ref of the NEXT take, then press [ok]
to validate. Two remarks: 1– the use of Arcan, Tarkan or
keyboard (p.58) considerably speeds up metadata entry;
2– [shift] [jog] accelerates letter scrolling 10x.
1 Scene and Take
The first screen displays 'Seq Scn Tak'. Press [ok] to go
down to the bottom line and use [>] or [<] to scroll along
the characters and modify them with [jog.] Press [ok] to
store and exit.
• The default template is nnnA/nnA.nn for 'sequence,
scene, take-gender and take #'.
- Sequence: three digits, followed by one character*.
- Scene: two digits, followed by one character*.
*'space', 'A' to 'Z', 'a' to 'z', '0' to '9'.
- Take-gender: t = t ime synced, p = pick-up, w = wild
track, a = announce, n = no good (keeps the take # for
the next file). This t-p-w-a-n list is scrolled with the [red]
button.
- Take #: two digits.
• An open XXXXXXX.XX template is also available, (see
AUDIO/TC.12 'ScTk Templt', p.31).
At each new take, the sequence & scene is maintained and
the take # is incremented by one. Modifying the sequence or
scene ID causes the take # to reset to '1', and the take-gender
to 't'. The rectangular screen displays the filetag of the NEXT
recording.
2 Comments
[jog] to 'Tk Comment' and press [ok] to activate the bottom
line where the former comment appears. Characters (200
max.) can be entered with [<], [>] and [jog] but it is much
easier to use a keyboard or a remote PDA with Arcan.
Depending upon the keyboard [insert] key toggle status, a
flickering square (insert) or a flickering pipe (overwrite) is dis-
played. Enter your comments. and press [ok] to validate.
note : to erase the comment line inherited from the preceding
take, press [shift] [esc].
3 Track-names
[jog] to 'TrackName 1', [ok] to go to the bottom row.
[shift] [jog] or keyboard's [shift] [up/down] arrows show the
available list of track-names.
Track-name completion relies upon a library of the last thirty
track-names in use. This automatic process speeds up track-
naming by letting you pre-store the names of the film's main
actors and swiftly recall them by their first two letters. Press
[ok] or [enter], and [jog] to 'TrackName 2', etc.
Track-names are modifiable at all times and are stored in
each and every audio file, this means that an ISO file car-
ries its own track-names.
Library cleaning
By [jog]-ing past 'TrackName 8' you reach 'Del TrkName',
[ok], select the track-name to be erased, [ok]. If you decide
not to erase it, press [esc]. In a bind and no time to name
the tracks of the next take, it is better to remove the former
take's track-names than to carry incorrect ones in the next
take.
Go to the track-name editing line (any track will do), and
press [shift] [esc]; the following generic names will replace
them : T1 to T8 on native monophonics; ms-M and ms-S on
M/S tracks ; MixRight and MixLeft on mixdown tracks.
Press a [track-solo] button to display that track's name in the
rectangular screen.
note1 : to allow for a possible entry from a PDA, the generic
track-names above are only recorded upon completion of
the take.
