RAW12 disappears after 4.0.8185.0 for SV305 camera

#1

Post by Planetibo »

Hello,
I have a SVBONY SV305 Camera.
I recently updated the SVBONY drivers and updated Sharpcap.
Since then, it seems to me that the RAW12 bit depth has disappeared.
Therefore, the Sensor Analysis is now wrong:

Whereas before, the values seemed normal:

I have tested the downgrade with each version containing the mention "upgrad SDK SVBONY" and it appears that with the following version SharpCapInstall-4.0.8185.0.exe, RAW12 mode is here.

After this version no more RAW12, it turns into RAW16.
