I'm looking for a versatile camera for analyzing golf swings (and ball contact) and also bowling releases.

For golf (indoor) I can control the light (within reason) and need tons of fps (in the case of looking at the ball contact). For bowling I need less fps but I can't control the light.

I know that for the Dahengs/IDSs etc where you have more control over the camera settings you can for instance reduce resolution to gain fps and adjust shutter speed to freeze frames (or allow more light) however this is mostly based on me inferring things based on things I have read.

Is there somewhere where things like this is discussed so that I can learn more so that I can make an educated guess on what type of camera (and sensor) I want to look for that is the best compromise for what I need? Google has let me down in my attempts to learn more. For instance when just looking at the information I can find on for instance the IMX287 I can't see any indication that I can get more fps at lower resolution but things I have read indicates that it should be possible.

My use case will be using Kinovea for as much as possible and python or C++ if needed to do the more advanced things (if needed).

So does anyone know of a place where things like this is typically discussed?

Apart from here there are some occasional discussions on the Golf Simulator forum, especially the Computer Systems sub-forum.

Maybe of interest also the Aravis discussion board, Aravis is an open source library to work with GenICam machine vision cameras. The forum is of course focused on the use of the library but you might find some interesting info there. (note: this library requires changing the driver of the cameras to the generic libusb one which typically makes them not compatible with the manufacturers software).

Yeah I think that's because it's not a feature of the sensor itself but of the firmware. Most likely all sensors are capable of this, even those in webcams, action cams or phones, but the on board chip and its firmware driving the sensor are exposing different functionalities.

Many vendors have an area on their website with "white papers" or a "knowledge base" or "application notes", with interesting info at the level you might be interested in, not necessarily specific to one particular camera.

Thanks!

You confirmed what I suspected about having there not being a "generic" forum but rather bits and pieces scattered around in places where the cameras are being used for specific purposes (like this place).

Good to know about the firmware. Looks like I need to download information from the camera manufacturers. I had this as my next step but then it is actually the first step. I can live with that even though it makes things a tad harder to filter candidates.
