I am struggling to understand how to reduce the BI file size when using a Hikvision camera.
I have uploaded the video section photo of the camera in question but can anyone please advise what settings I need to adjust to make the BI file size smaller?
Recording can only begin on a keyframe (I frame) so if you record on motion detection then you need to set the pre-trigger video buffer (in Blue Iris camera properties > Record tab) equal to your I frame interval divided by Frame Rate which in this case is 50 / 12 or about 4 seconds.
