yesterday a livestream by means of ATEM mini extreme and a BMPCC 6kpro.

my previous solution to disable the camera control with the
bidirectional micro converter also failed by using the new 3G converter.

so the 6k pro again directly to the ATEM and thus I started the stream.

we also always record this in the camera, but yesterday it was so that the camera
interrupted the recording every moment.

was used as always an angelbird CF pro Cfast2.0 card.
was recorded, due to the limitation by the camera control in 6kdci BRAW with 25fps.

in the evening after the stream i did some tests to see if the camera (was used the first time)
or the card was the problem.

without connecting to the ATEM, recordings up to the full capacity of the card were
possible without interruption.

as soon as the HDMI cable was reconnected to the camera, the interruptions were back.

but when using the old bidirectional converter, the camera control was deactivated again.
(for setup see at the old picture)

so i ask BMD to take care of this problem and finally give us the possibility to prevent
the camera control either in the ATEM software or in the camera.

but also the possibility to use again at control of the camera via the ATEM recording in prores,
because here the BRAW 6k files are unnecessary and a madness!!!!

ATEM mini extreme firmware 8.6.1
ATEM software control 8.6.4
BMPCC 6k pro firmware 7.3.1
micro biconverter 3G firmware 7.5.3
micro biconverter firmware (latest ??? - cannot see in the app - but should 7.3.2)

old picture of a working setup without camera control:

Can’t you use a HDMI CEC killer?

unfortunately i don't have any of these devices, because this problem didn't occur until now : -(

have now ordered some.

however, this does not change the recording aborts when the camera control is active!

It’s not a device:

I use it when connecting my MacBook 2011 to the Atem: no remote control without this CEC killer.

Why do you have the output of the ATEM Mini connected to the input of the 3G micro converter? This should not be necessary if you only want camera control. The ATEM Mini can speak bi-directional over HDMI. The two SDI connections are indeed necessary.

That’s to see return video.

with the old converter it will kill the camera control - but not on the new 3G :- (
i don't want camera control!

i do the stream without the converter - direct HDMI-HDMI
and the incamera record stops every 49 sec.

no, the old converter kills in this config CEC over HDMI

i forgot that the new 3G allow CEC : -(

but, no one else has these problems with recording stop?

.

so, after a few tests more:

the recording failure does not affect my 4k with firmware 7.3,
but only the 6k pro with firmware 7.3.1

the new firmware update 7.5.1 should have fixed the problem ;- )
