What are some ways (if possible) to sync an entire A/V system to SMPTE? |

SMPTE can be used in real-time. I'm using 24fps when tracking our sermons and 24 fps/df during post allowing us to keep 48k sync during the editing and mix process. Now what I'm looking for is way to have a sync system where all I need is to plug any paticular device to a clock or ctrl system. Not so much automation but more of a device to sync the team (Tech, camera operators, etc) by either slaving the equipments own internal clock to the house clock or by using an external clock display if the said device does not have one. |

I suppose I understand what you are getting at. The broadcast industry's response to control is the General Purpose Interface (GPI), usually a simple contact closure that is triggered by an automation computer. The computer may be slaved to SMPTE or GPS. For what it's worth, companies like ESE and Torpey offer Master Clock systems that can be synced to a master clock so that everyone sees the same time display (a Google search on Master Clock reveals a myriad of devices). That time display be optionally linked to Global Positioning Satellite (GPS) for atomic-clock precision. |

1. Using a global timecode clock that all equipment and personal respond to is much better then having to rely on regular time clocks that 8/10 times our off by a minute or two. 2. It REALLY helps if a piece of equipment can automate itself to start whatever function it has been assigned to do at whatever point in the timecode the director would want it to start at. So instead of having A2 Joe press record at 10:30 am I can just set the machine to start recording at 00:30:00:00 after a 30sc preroll. 3.It benefits the Stage director when giving cues because he or she knows that everyone is looking at the same clock. 4. It REALLY helps during post production and OB becouse all the engineers both live and studio that I personally know work strictly with TC no matter what role or type of production they are doing. 5. Most of our equipment is TC ready so I figure lets do it.. |

Maybe I'm misunderstanding the application but I think the problem some see is that your pastor, musicians, congregation, choir, etc. do not sync to timecode and very few services occur on a frame accurate basis. How do you address continuing to record with timecode for post-production the sermon that runs over a bit without also then potentially triggering the next timecode based scheduled event? If the organist starts a few seconds ahead of time do you have the hymn lyrics showing up on screen after the related passage has already been played? Also, if you had a system all tied to timecode cues, why would you need a Stage Director giving cues, wouldn't the cues all be automated? |
