SharpCap (v1.3 onwards) now supports capturing from Basler Cameras that use Pylon API. In v1.3 the support should be considered to be in beta - please use it and report any problems you encounter!
You need to install Pylon 2.3 before the Basler Cameras will be usable. When installing the Pylon package, you must ensure you install the 'pylon .NET runtime' component of the installer.
Capture from Basler cameras is to SER files rather than AVI files used for DirectShow cameras. SER files can store images up to a depth of 16 bits and can store raw frames (ie still in Bayer format direct from the colour camera). Both Registax and AviStack can read and process the SER files written by SharpCap.
Do *not* use the Basler Genicam option in the camera menu - this connects to the camera via the Basler DirectShow emulation layer. If you choose this you'll only get 8 bit colour depth and hardly any controls will show up in the right hand panel. Also note that swapping between Genicam and the full Basler camera support requires that you close and re-open SharpCap.
