Hi,
I never used this tri-level sync box from Lockit. I have a PD-6 and
the camera will be a Sony HD 900F that runs with 23,976 FPS TC.
Which TC rate should I set up for the PD-6? And at the Denecke slate
generator? In case to send TC to slate through Comtek is this change
anything? How many times should I re-sync the Lockit box? At the post
do they need to use the pull down? How do they manage the automatic
sync?
Thanks for help.
All the best,
Paulo Ricardo Nunes |

Nominally, the PD6 and Deneke slate should be set to 29.97 unless post
(picture and sound) have specifically asked for 23.976.
It makes no difference if the slate TC is from the Deneke generator or
a Comtek RF link.
The Lockit box on the camera should be set to 23.976 and Tri-Level
sync as described as described for Sony Tri-Level sync cameras in the
Ambient manual.
Re-Sync every five hours. Preferably you should use an Ambient Master
Controller to set the Lockit, PD6 and Deneke generator every five
hours. The Master Controller will identify any significant timecode
drift with any specific component.
No pull down is required with 23.976 & 29.97
"Automatic" sync is dependent on post process

Just to add that both the Ambient Clockit and the Denecke SB-T will
hold frame accurate timecode for 12+ hours, over 18 hours +/- 1 frame
is possible. >> Stay informed about: tri-level sync box Lockit |

Indeed, but someone may have retuned the Lockit and then there's the
sync of the PD6. A well set up system should only need a check rather
a re-sync after lunch.

I've never quite understood the "check" principal? If you're going to plug a
cable into a device to "check" it, whey the heck not just re-jam it? >> Stay informed about: tri-level sync box Lockit |

The intent of trilevel sync boxes if primarily to keep multiple
cameras and their external timecode "gen-locked" without the need for
long cables to a master source. For a one camera production, a
trilevel sync box is rarely if ever necessary. In this case, normally
it should suffice to occasionally jam the camera to the audio recorder
(or vice-versa). If the convenience of a portable timecode source for
jamming a camera to the audio recorder is wanted, a more simple device
such as the Denecke SyncBox will suffice.
Trilevel sync is for hd camcorders, not sound.

I have found when I am doing multitrack recordings (24trk) on a video
shoot, the trilevel sync is needed to lock the recorder both to time
code and word clock. So, if you are doing more tracks than the Deva
16, a trilevel sync box that also can supply word clock is needed.
Additionally a digital board benefits from having word clock.

Thanks David,
More questions, if don't mind.
> Nominally, the PD6 and Deneke slate should be set to 29.97 unless post
> (picture and sound) have specifically asked for 23.976.
They are syncing at a Final Cut station. The editor said it's a 23,98
FPS project. The first test we did I tried 29,97 on PD-6 and 23,976 at
camera. The editor couldn't sync at all. He said that Final Cut read a
30 FPS TC at BWF files. That sound strange for me. He said he needs
sound and picture run 23,98 FPS.

The camera rental consulant said theres is no need to plug the tri-
level. Just if you have more than one camera. Like Glen said maybe
it's not for sound but for camera's purpose.

And what hapens if I running in 23,976 FPS with audio editing?

Thanks Glen.
We will use 2 cameras for a few days. In that case both cameras must
me "gen-locked" as you said. Genlock PD-6 is needed? To jam PD-6 to to
lockit (considering PD-6 a master clock) I just connect PD-6 TC out
(XLR3) to lockit TC in (lemmo 5). Is it means that the word clock is
jammed too?

If you are working with HD cameras use both the TC and WordClock
(Genlock on the camera) connections on the camera. Make sure the
cameras are set to free run and plug the Ambient Clockit in while the
cameras are powered off. See Peter Grays website for the proper
setting for your camera.
http://www.jkor.com/peter/lockits.html
you don't need to have a Ambient Clockit box attached to your PD6
since it will be the master clock. >> Stay informed about: tri-level sync box Lockit |
