Time Code

12. Time Code

In modern electronic post-production time code is often used today. Quartz-synchronized film, sound and video recordings have been made possible through the use of equipment with TC-capability.

The ARRIFLEX 16SR 3 is equipped with a TC generator which produces 80bit time code corresponding to SMPTE RP136, Format Type C. The TC generator can be set using the CCU or a master clock. The precision of the TC generator ensures that for 8 hours after the synchronization (at 0° C - 50° C) the difference remains less than one frame. Every frame is therefore clearly identifiable for synchronization or editing lists. After 8 hours a further synchronization process should be carried out.

With the TC-Output the ARRIFLEX 16SR 3 can also take on the master clock function in a TC system.

TC recording is still active when the camera is synchroinized using the external synchronization unit ESU on a video monitor. The maximum difference between the frame rate of the external synchronization and the TC frame rate is 1%.

Time code is recorded in the magazine corresponding to SMPTE RP114 at standard speeds 24,00/25,00/ 29,97/30,00 fps and at 23,976 fps.

The TC information also includes speed of recording which is described in connection with time code as frame rate. For the ARRIFLEX 16SR 3 the valid frame rate is always the most recently set standard speed.
