Video Code Type:
H265 is an algorithm for compression of data that is classed as High Efficient Video Coding
(HEVC) that gives you lower processing overheads and
Savings of up to 50% hard drive storage space can be made.
Video Code Level: Baseline / Main Profile / High Profile (Default = Main Profile)
Bitrate control: CBR (Constant) / VBR (Variable Bit Rate)
The Bitrate Type can be set to Constant or Variable although Constant is the default setting. The
bitrate type is based on the complexity of the scene. If the subject matter comprises of large areas of
the same thing i.e wall, sky, water etc., then use constant bitrate but if the scene is more complex
with smaller areas of detail such as a busy street, variable bitrate is more appropriate. Inappropriate
bitrate settings can adversely affect processing speeds.
Bitrate Mode
Predefined / User Defined
Predefined is used if you want to use predefined settings or if you wish to use your own settings
then select User Defined mode.
Bitrate:
Select from a list of predefined bitrates
displayed on the right.
or
User Defined: Use the default bitrate of 4096 or enter a
bitrate between 256 ~ 16384
Note:
Range of MainStream is 256-16384 Default = 4096
Range of Substream
Range of Mobilestream is
Audio
Enable audio for each bit stream.
I frame interval: The I frame interval is the number of frames before a new reference frame is
created. You start with encoding a full frame and then holding changes to that frame on the next
frame until the count is reached. The default setting is 30 for mainstream, 50 for substream and 20
for mobile stream. Note that lag time issues may occur when too many reference frames are set or
alternatively when too many changes occur across each non reference frame. Therefore individual
tests will provide the most accurate setting.
H264 / H265 (Default H265) Must reflect the IP camera setting.
is 128 - 4096 Default = 1024
8 - 1536 Default = 512
thus uses less disk hard drive storage space.
