Video/Audio Configuration

Target Frame Rate

NTSC: 30, 15, 10, 7.5, 6, 5, 3, 2, 1, 0.5. Default = 30.

(frames/sec)

PAL: 25, 12.5, 5, 2.5, 1, 0.5. Default = 25.

This number represents how many frames the VBrick will send out each second to carry the video to an H.264 player. The word target is used because the VBrick can vary its frame rate slightly in response to the amount of motion in the movie or camera output. See the Rate Control Setting parameter below for more details.

 

 

Frame rate is the number of "frames" the VBrick sends in a second

 

 

for an H.264 player to display. Moving pictures are made up of a

 

 

rapid series of "still" pictures that move so fast that the "illusion" of

 

 

motion is produced. A frame is one such "still" picture. Regular TV

 

 

programs in the U.S. run at about 30 frames in a second; and the

 

 

more frames presented in a second; the smoother the motion

 

 

contained within the video will appear. Encoding and transmitting a

 

 

frame requires the use of data, so that, when considering a particular

 

 

bit rate, sending more frames demands that each frame contain fewer

 

 

fine details.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

IDR Frame Interval

0–30. Default = 4. The frequency in seconds at which IDR (Intra

(sec)

 

Dynamic Refresh) frames are inserted for Seek, Fast Forward and

 

 

Rewind functionality. Higher values create fewer random access

 

 

points and better compression efficiency. Lower values create more

 

 

access points but with less compression efficiency. Zero means all

 

 

frames are IDR frames.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Rate Control Setting

Default = 60. The size (in number of frames) of the video encoder

(frames)

 

buffer. This parameter allows lets you trade-off video quality with

 

 

how tightly rate control is imposed. A larger number increases the

 

 

number of frames over which the target number of bits can be

 

 

distributed. This means that the average bit rate, measured over small

 

 

periods of time, can fluctuate more around the specified target bit

 

 

rate. The quality of the video however will be adjusted more

 

 

gradually, providing a smoother transition. A smaller number will

 

 

reduce the fluctuations around the target bit rate but will also lead to

 

 

faster changes in video quality (which can be visually undesirable). In

 

 

bandwidth-restricted networks with little tolerance for bit rate fluctuations, a

 

 

smaller value is recommended; otherwise, use a larger value.

 

 

 

 

 

 

 

 

 

 

 

 

In-loop DeBlocking

Reduces blocking artifacts but may introduce a mild but undesirable

Filter

 

blurriness into the stream. Default = Enabled.
