Remote Control Protocol - query valid values?

PostSun Nov 04, 2018 10:08 am

Is there any way to query valid parameter values in the SDI/Bluetooth Remote Control Protocol?
Like "System Language", Gain, Dimension=Resolution,...?

It sounds very wrong to hard-code these for specific canara models and even firmware versions when developing a client.
The April 2019 documentation also seems to be a bit outdated.
Only specifying resolutions up to UHD (missing 4K and 4.5K)
and 1.1 Gain up to ISO 1600
and the Audio Input Type not being separate for Left+Right and not having values for the BMPC4K Mini XLR.

.. and a bit inconsistent. Naming the ISO in 1.1 "Gain" but in 1.13/1.14 "Gain" and "Iso".

How do you specify these strange US frame rates like 29.97 with an integer?

Hi Marcus,

No, we don't have mechanism for querying valid values in the Camera Control Protocol.

To set frame rate to 29.97 fps, set 1.0 Video mode parameter - Byte [0] = 30, Byte [1] = 1 (M-rate)
