SharpCap camera settings not recording frame rate

#1

Post by StuartT »

Not sure if this is a bug or not but I seem to recall that on my ZWO cameras, the text file includes frame rate. On my new Player One camera this is not present (see below). The duration and number of frames is recorded (thus allowing me to work it out!), but doesn't frame rate usually appear as a separate field?

Code: Select all

Hi,

the frame rate setting is only written to the capture settings file for webcams (maybe you were using your ZWO via the webcam driver?), which have this as one of the controls that you can adjust. In this case though, it is a target frame rate for the camera, not the true frame rate.

Best to just go with frames divided by time I think :)

cheers,

Robin

ok, thanks. How would I check which driver SharpCap is using for my ZWO cameras?

Hi,

when you select the camera from the menu, check which section you select it from - for instance your ZWO will appear at least twice - once in 'ZWO ASI Cameras' and once in 'DirectShow cameras' - the latter would be using the webcam driver

cheers,

Robin

Any chance this frame rate calculation could be added to Camera Settings log in the next release? It would just save me having to calculate it each time. You already have the two quantities needed to derive it after all, so it should be a simple matter. Thanks

Code: Select all
