Hey folks,


I was hoping the wider community could help me with a problem I had on a short at the weekend.


I prepped a job on Friday, Ultra 2 sled, Ultrabrite2 monitor and an Alexa, it was an older Alexa with max internal recording capacity of ProRes 4444HD. The image on the UB2 was perfect during prep no problems. Mon out - sled - UB2 - all good.


The cameraman wanted to record higher resolution via an external recorder/monitor - Odyssey 7Q. This all seemed fine, he just needed to buy a license from Convergent-Design to allow him to access this.

All that was required from the camera was a single BnC (Rec Out) to the recorder and this would achieve 2.8K image recorded on the Odyssey's SSD. 


However I didn't get the chance to test the camera again until we were on set the next morning.

With the same cable configuration as in prep my image on the UB2 was now distorted, horizontal split screen two thirds up the screen, jittery/ staggered image.


I am not a tech wizard but I imagine the problem had something to do with the external recorder being up-resed, affecting the Mon Out port.


Has anyone experienced anything like this in the past? Or does anyone know of or can suggest a way around it?

I have emailed Tiffen with this query and with the same questions. However any suggestions would be welcomed.


Many thanks,

I have seen that before, I think its mon out settings/or perhaps in project settings on alexa (to do with dual output setting when recording raw) 

Also if I remember correctly we needed two BNCS from rec 1/2 going into the odyssey to record raw, and you would need two cards in the odyssey to go into high speed.

Thanks Andrew, I went straight for the monitor's set up menu instead of the camera's. Good to know, thanks again.
