View Full Version : Help Needed with Atomos Samurai

Previously, I had been using the Atomos at 1080i with out a problem.
I am currently having issues recording 23.98 with the Samurai

F3=HQ 23.98 PsF
Atomos=3:2 23.98P ProRes HQ

If I set the F3 to 23.98 PsF it works fine, but I can't use the Zacuto EVF witch requires 1080i
When I set the F3 output to 59.94 (2-3) the EVF works, the Samurai detects the pulldown (monitor button lights) but I get a nasty studder with interlacing.

I was under the impression that the Atomos was supposed to detect and remove the 3:2 pulldown.
Am I totally missing the point here? Can anyone give me any suggestions?

Thanks

Camera set to 23.98 HDMI output 60i
Samurai connected to SDI A
Zacuto to HDMI out

"Samurai connected to SDI A"'

Ah... As opposed to the plain SDI out?

SDI Out & HDMI carry the same signal with pulldown added. Recorder goes to SDI A.

By the way, whomever moved this thread should know that this is an F3 thread problem. It is not a recorder problem but a connection to the F3 problem.

Ok, it's working. Again my thanks

And for the benefit of those going through this for the first time:

At first it didn't work when I switched on the dual channel SDI out (for channel A) but then I noticed that the menu no longer said (SDI/HDMI) on/off, it now just said (HD HDMI) on/off . Once I changed that it appears they're all working, and no pull-down is indicated on the Samurai.
