If you had no trouble recording high speed before - most likely it is the change in firmware that is the issue.
I would try to contact S-two or read the manual.
On the camera side I would lock the sensor to the RecOut and make sure the project speed is correct and you set the camera to 4:2:2 1.5Gbs DL I do not thnk that the OB-1 supports the 3G yet.
Many thanks Mr.Guenter for the reply. .
the project speed is correct,and the camera setting is 422 1.5G DL but still can't run in RP188 TC
i still looking forward for the OB-1 highspeed setting set TC in RP188
please send to my email firstname.lastname@example.org for further information,can i got your email mr.Guenter ?
