Hello,

I am trying to record some videos using a NexiGo60 webcam, and as the light conditions are not ideal, when recording the video, the real time is decreased from what I filmed.

I know that the webcam has different resolutions, but cannot find the way to change it from Bonsai. I am using the node VideoCapture Device, and recording the video with the node VideoWriter.

Thank you!

Hi,

You can select among the camera's available modes in the properties of VideoCaptureDevice. Format, for instance, exposes the available resolutions and fps. Additionally, using CaptureProperties you can define some additional variables like the exposure.

Does this answer your question?

Best,

B

Yes, it answers my question. It's with the Format option!

Thank you,
