H.264+
H.264+ is an improved compression coding technology based on H.264. By enabling H.264+, you
can estimate the HDD consumption by its maximum average bitrate. Compared to H.264, H.264+
reduces storage by up to 50% with the same maximum bitrate in most scenes.
When H.264+ is enabled, Max. Average Bitrate is configurable. The device gives a recommended
max. average bitrate by default. You can adjust the parameter to a higher value if the video quality
is less satisfactory. Max. average bitrate should not be higher than max. bitrate.
Note
When H.264+ is enabled, Video Quality, I Frame Interval, Profile and SVC are not configurable.
H.265
H.265, also known as High Efficiency Video Coding (HEVC) and MPEG-H Part 2, is a compression
standard. In comparison to H.264, it offers better video compression at the same resolution, frame
rate and image quality.
H.265+
H.265+ is an improved compression coding technology based on H.265. By enabling H.265+, you
can estimate the HDD consumption by its maximum average bitrate. Compared to H.265, H.265+
reduces storage by up to 50% with the same maximum bitrate in most scenes.
When H.265+ is enabled, Max. Average Bitrate is configurable. The device gives a recommended
max. average bitrate by default. You can adjust the parameter to a higher value if the video quality
is less satisfactory. Max. average bitrate should not be higher than max. bitrate.
Note
When H.265+ is enabled, Video Quality, I Frame Interval, Profile and SVC are not configurable.
Profile
This function means that under the same bitrate, the more complex the profile is, the higher the
quality of the image is, and the requirement for network bandwidth is also higher.
I-Frame Interval
I-frame interval defines the number of frames between 2 I-frames.
In H.264 and H.265, an I-frame, or intra frame, is a self-contained frame that can be independently
decoded without any reference to other images. An I-frame consumes more bits than other
