Do you have this set to high ?

well thats always a good thing, but it always amazes me how some updates will screw up some users and not others. To be honest you aren't missing anything by staying on 5.5.4.5 Maybe try the next one

Is this on ? If it is try toggling it off and then on. You must have some setting that is causing it. I have never seen it before.

These settings will get you up and running if you want to add your doorbell to Blueiris. You can tweak them to your liking from there, but these seem to be working great for me.

I am not seeing this on mine and I have 7 groups. I tried several and they all work. Does it work right in the Blueiris GUI ?

yes, that is same time I was getting the 0 sec clips, during the ending and beginning of the hour clips. I would try to send support a message, hopefully they can help you out.

same with me, I never use to have any issues withthe "0" sec clips, but it only happened on 2 of my 16 cams and like you mine all show /1.00 on the key frame. So by going by the article I added some time on my pre trigger buffer and the 2 troubled cams and it fixed mine. Mine are only 2MP ...

this is talked about here on the forum...way at the bottom:

look for this:

do you have this option checked on old pc ?

I had this on 2 of my cams. I just added 1 more second to my pre-trigger video buffer from 1 to 2. It does work with your I-frame setting in camera as mine also is set to 1.
