Basically, the Ursa follows the F4, whatever it's set for, when they are connected. I plan on leaving them connected for the majority of the shoot which is interior/dialogue work to give me an audio track. The Ursa TC will continue on if disconnected, and is now reputed to be quite accurate. I plan to disconnect the snake and let the 2 units run separately in parallel when shooting the action/outdoor stuff with a camera mounted shotgun for a scratch audio track as backup, and just reconnect the BNC/TC when doing a battery change on the Ursa to re-sync.
URSA won't hold sync for any extended period of time.
Thanks all. The Tentacle sync keeps coming up, and it sounds like a good product. Maybe next job (that pays). I'm really just shooting this short to help build a narrative reel and sort through this new gear. I always just did the dumb slate/audio sync in the past, but want to try TC out. I will have a scratch audio track on the video if the TC fails for any reason. They claim that, unlike the earlier Ursa cameras, the BM UMP 4.6K version will hold sync for a day or until the battery change. The TC route looks like it will be easier for matching up dailies (shooting RAW) and transcoding for the edit. Thanks again.
Don't believe it! No camera you can fully trust 100% to hold sync throughout the day.
Oh, and it isn't normal for a soundie to have a "narrative reel".....
Well, the idea(and correct way to do it) is that you have a sync box on every piece of equipment that needs to be/stay in sync. Unless it's something like a Sound Devices recorder with a high quality Ambient TC generator/reader built in, in which case you would be safe not having a sync-box on the SD, but jam all of the sync boxes to it and then put the boxes on the camera. That's how we usually do it.
ric8138, are you shooting this in NC?
Like Sound Devices / Zaxcom / Aaton / Sonosax / etc, the Zoom F4/F8 are perfectly capable of holding sync all day.
