Dahua I-Frame Interval Question

Undisclosed Integrator #1

What does Dahua mean in their camera encode settings when they say I-Frame Interval 10~150?

Does a value of 10 mean that you will get a new iframe every 10 seconds?

Running Dahua rtsp through a program to create HLS stream.

It has a lot... a lot of artifacts behind moving items.

The FPS is set to 20 by default and the IFrame Interval is set to 40.Does that mean a new IFrame every 40 seconds?

I lowered the IFrame Interval to 10 and it is better but I still get artifacts on moving items.

Some of our other Dahua cameras have IFRame Interval set to 1 second.

Any direction?

Thanks
