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.
