Configuring IDS camera in freerun mode

[Hannah Payne]

I'm just getting started using Bonsai to record video from an IDS camera (UI-316xCP-C). I'd like to acheive a high frame rate (>120 fps) and configure some other parameters like the ROI. I have a simple program that successfully records video *without* providing an configuration file under uEyeCapture>ConfigFile, at roughly 30 fps. However, when I save a config file (*.ini) from the uEye Cockpit software and specify that file, it seems to only save one frame (total file size of the resulting *.avi file is 6 kB no matter what). I've tried just saving a file containing the default uEye Cockpit parameters, same result. 

Any ideas how to both specify a configuration file, and still record video continuously in freerun mode?

My program and (both default and custom) configuration files are attached.

I should mention that this program does correctly save the frame number and GPIO states. Also, if I right click on the Image node I can display a preview, even though the video still doesn't seem to save. 

I've tried running Bonsai as administrator and made sure I'm using Bonsai64.exe (Windows 10, 64 bit)

Any other ideas for troubleshooting? Or more general tips for how to debug programs in Bonsai?

Hi Hannah and welcome to the forums!

Sorry for the delay replying. This sounds like a strange situation. Can you see the live video streaming if you just visualize the Image node without the VideoWriter?

Also, I noticed from your workflow that you are using a preview version of bonsai (2.4-ctp). Would you mind trying the same workflow on the stable version (2.3)?

Belated update: The problem turned out to be the default format settings in the uEye Cockpit. It was set the RGB32, when I changed it to RGB24 multiple frames are saved. I also installed the stable version (2.3).  

Thanks!
