Motion blur and low frame rates

[Numb-nuts 1]

Can anyone tell me what is happening to the recording in this clip?

This is a new camera with a slow shutter for night viewing, sensitivity-up is on.

I think this effect is called motion blur. The recorder setting is 12fps@ CIF and at D1 I cannot get higher than 6fps

That is not motion blur.

That looks like the results of a poor/overly aggressive compression algorithm.

So for those of us that haven't a clue what tht means what do you think is the problem, settings or what?

What do you think is happening here then, I am confused as I have never seen this before.

With sense up it will lower the max frame rate.

 

With a slow shutter setting of 1/6s like some IP cameras allow you to do you can get no more than 6FPS, because it needs that time to take the picture (assuming progressive scan IP camera).

 

Analog cameras at night nominally are two 1/60 sec exposures interlaced to give you 30FPS. If you apply sense up will slow that down accordingly also.

 

I'd first look at the compression settings in both the camera and the DVR, you have some artifacting going on there - same effect you will see with a DSLR if you compress it too much in a JPEG.

Turn up "quality" settings any where you can, that should compress it less.

It was the bit rate settings being too low. The settings demon must have turned them down when my back was turned
