SMPTE

Society of Motion Picture and Television Engineers (SMPTE) began work to develop a

standardized synchronization method for the new medium. The resulting ’SMPTE time

code’ is simply the recording of time information, in hours(HH), minutes(MM), seconds(SS)

and frames(FF), as a digitally encoded signal on one of the tracks of a multi-track audio or

video tape. There are a number of frame rates in use today:

24 used in motion-picture film

25 EBU standard (European Television)

30 NTSC monochrome standard (audio)

SMPTE Time code can be recorded to an audio track (Longitude Time Code, or LTC) or it

can be recorded as part of the video signal (Vertical Interleave Time Code, or VITC).

Either way, the time code ’word’ is the same.

RECORDING AN SMPTE TRACK

The SMPTE can be used on the Studio desks in 2 ways: INTERNAL TIMING or EXTERNAL

TIMING. In both cases, it is possible to record up to 24 tracks (Studio 24/Studio 24 SC) with a limit

of 24576 “events” recorded for all tracks. That means, it is possible to record a memory changes or

flash, register cross time variations, page changes. Furthermore, when a track is enabled, it is

possible to work manually on the lights and/or scanners and/or registers.

In addition Studio lighting desks has been designed to work with the worldwide SMPTE standards:

24, 25 and 30 FPS (Frames Per Seconds). The desk automatically configures the parameters, so

that user has only to “plug and play” with it.

INTERNAL TIMING

When working without any external devices connected, please proceed as follows:

1. Hold down keys <ENTER> & <PLAY> for at least 4 seconds, until the led blinks.

2. Now, exactly at the moment you want to START the recording, press a key of the Register

section (1...24) selecting the track to record. If the track was already done, then it will be

replaced.

3. Now you can proceed to record your show, selecting the output memory for each show period.
