Setup Description

Setup Options

Time Code: Frame Rate

Sets the time code frame rate. All common time

code frame rates are available.

• 23.976 – used with high definition video cameras
• 24 – to sync audio to film where no transfer to

NTSC video is expected
• 25 – to sync sound to PAL video
• 29.97 – to sync sound to NTSC video shot in non-

drop frame mode
• 29.97DF - to sync sound to NTSC video shot in

drop frame mode
• 30 – to sync sound to film where transfer to NTSC

video is expected
• 30DF – to sync sound to film for transfer to NTSC

video in drop-frame mode
• 30+ – Records at 48.048 sampling rate at 30

frames per second but stamps the file at 48kHz, 30

frames per second

Time Code: Mode

Sets the mode for the time code generator

• Off – time code not active, recorded or output
• Free Run – time code is initialized from the jam

menu and then runs continuously regardless of

record mode
• Free Run Jam Once – time code is initialized from

an external source and updates itself to the external

source when reconnected
• Record Run – time code is initially set from the jam

value item in the jam menu. Time code generation

runs only during recording generating continuous

time code from file to file.
• 24 Hr Run – time code is initialized from the system

clock on startup and enters free run mode. Time

code is updated if the time of day clock is adjusted.
• Ext TC – applies external time code to the recorder

directly. The internal time code generator has no

effect.
• Ext TC/cont – applies external time code to the

recorder; internal generator continues to run if time

code signal is lost. Useful for time code transmission

over RF
• Ext TC-Auto Record – applies external time code

to the recorder. Unit enters Record when time code

runs and stops when time code stops.
• Ext TC/cont-Auto Record – applies external time

code to the recorder; internal generator continues

to run if time code signal is lost. Unit enters Record

when time code runs and stops when time code

stops.

Time Code: Hold Off

Sets the duration that a valid time code signal has

to be recognized by the 744T before generating a

new take while in Ext TC-Auto Record and Ext TC/

cont-Auto Record modes.

0.0 to 8.0 seconds adjustable in increments of .1

seconds

Time Code: User Bits

Sets the time code user bits generated by the 744T.
mm – month

dd – day of week

yy – year

tt – take number

uu – user-defined

• Not Used – user bits are not set or output
• mm:dd:yy.tt
• dd:mm:yy.tt
• uu:uu:tt:tt – user bits are set to 4 user definable

digits with 4 take digits
• uu:uu:uu:uu
• tt:tt:tt.tt – user bits are set to the take counter for

all 8 digits
• mm:dd:yy:uu
• dd:mm:yy:uu
