Bosch Cam Dinion 7000 HD Encoder params?

[ramx2 0]

Dear CCTV Gurus,

 

Need assistance concerning the encoder profile in Dinion HD cam..

 

We have the following settings to play with:

 

HD- Image Optimized (Profile)

 

Target bit rate: 8000 kbps

Maximum bit rate: 12000 kbps

 

 

1< GOP structure: IP- IPB - IBBP

2< I-frame distance (It's set to Auto)

3< Min. P-frame QP (It's set to Auto)

4< I/P-frame Delta QP (It's set to -6)

5< Background delta QP (It's set to 13)

6< Object Delta QP (It's set to -12)

 

Now, what I need is the best picture quality with the best lowest bit rate,what's your suggestions ?

 

Little brief from the datasheet:

 

Expert Settings

if necessary, use the expert settings to adapt the I-frame quality

and the P-frame quality to specific requirements. The setting is

based on the H.264 quantization parameter (QP).

GOP structure

Select the structure you require for the Group of Pictures

(GOP). Depending on whether you place greater priority on

having the lowest possible delay (IP frames only) or using as

little bandwidth possible, you choose IP, IBP or IBBP.

I-frame distance

Use the slider to set the distance between I-frames to Auto or

to between 3 and 60. An entry of 3 means that every third

image is an I-frame.The lower the number, the more I-frames

are generated.

I-frame quality

This setting sets the image quality of the I-frames. Select Auto

to ensure that the maximum bit rate is not exceeded. Auto

automatically changes the I-frame quality to the settings for the

P-frame image quality.

P-frame quality

This setting adjusts the maximum image quality of the P-frames.

Auto automatically adjusts to the optimum combination of

movement and image definition (focus). The value 9 represents

maximum image quality, a value of 51 represents minimum

quality. With the slide control, define a control range from a

chosen value to 51. The encoder delivers the best possible

quality within this control range while maintaining the

maximum bit rate.

 

Help appreciated,
