Dear All,
I've been reading this forum for some time and usually was able to find what I needed. Today I stepped on an issue which I could not trace by myself.
I've been using BI for more than a year at house. Recently I've set up capturing of pictures every 60s in the Post menu in BI. The problem is that randomly, quite often (like every few picures), the picture is recorded empty (i.e. it contains a pictogram and is of ca. 3kb size).

When I open BI on the computer (it works as a service), usually it posts a good picture at once. The picture is taken a the full minute time eg. 19:13:00, i.e. in the time when recording the motion picture happens.
The picture is uploaded to a remote FTP location successfully. The problem is that the file is often containig only a dummy symbol of picture. I tested with a local path as well. Same story.
Have I set anything wrong? I know, there are other ways to do this, but I think that such function is something basic and simple, and should probably just work. So I guess, there's some setting I need to do.
The motion footage is recorded well. If I add recording JPGs in the Record menu, they are captured fine.

BI 5.9.9.11, 5 cameras, Xeon CPU, Nvidia K620.

Recording is set up for few seconds every minute, just to be able to view a kind of time lapse.

Look at the camera status window and make sure the FPS/Key rate is set to 1, might fix the problem if it is not set to 1
 
Thanks, Bruce.
I think it's been set to 1.

Any other ideas, people, please? Has anybody met such behavior? DB fixed, no change.
Video stream is H265. Does it impact anyhow?
