Timecode & AVX latency

Recommended Posts

Hi,

 

New to the community and learning quite a bit about location sound mixing. I was hoping someone might be able to shed some light in regards to using a timecode device with the following gear.  I would like to add Tentacle Sync(s) and/or UltraSync One(s) to speed up post production within Davinci Resolve Studio.  Since the Sennheiser AVX system introduces 19ms of latency, I would have to compensate the boom mic for that latency within my Zoom F8/F6. If the audio sync is now off from the video timecode by 19ms, how can I address this before bringing the project into my NLE?  Is there some kind of compensation within the recorder or timecode device that compensates for this discrepancy?

The Zoom F8 offers audio offset (input/output delay) on each channel. Check the manual for specifics (because I sure don't know them).

 

And like Al says, 19ms isn't a bunch. At  30fps, you're talking about 33ms per frame. At 24fps, about 42ms. That's top of my head, so double check. But you're not talking about a lot of delay. 

 

And Bouke makes solid software. So that's a good thing too. And I'd guess there's an offset option in Resolve; haven't looked, though.

 

Finally, I get that it might not be your call, but production could consider spending less money on cameras and a bit more on sound.
