Alexa Genlock

[nickreich]

Hi All,

I usually see Arri Alexa Minis on my jobs, but have a shoot coming up with three Alexa XTs. It's been years since I've seen a full-size Alexa, so can anyone confirm that they still can NOT take external Genlock from a Lockit box (unlike a Mini or Amira - which can take either Tri-Level or Genlock to TC)? This is a Concert shoot - so I'd normally recommend Genlock. 

 

thanks, nick

Don’t the minis derive their clock from the incoming timecode?

[nickreich]

Yes, as I said in my original post, the Minis can use either separate tri-level sync OR the incoming Timecode to Genlock the camera. The Amiras can do the same. It appears that the Alexas (full size ones) don't have the ability to Genlock any way. That's what I'm looking for confirmation of (hoping I'm missing something).

Since Genlock can interfere with the scanning process of cameras I have for many years left Genlock decisions to the camera department.

No, there’s no Genlock on the Alexa XT. 
I find it strange, because everything is there: there an unused BNC input called „Sync In“ and two Alexas can be synced to sensor synced operation, but no Genlock...

Thanks Constantin, I thought that was the case, but was hoping it had been enabled since I last used one.
