Below is an explanation of the fields on the Encode Mode screen:
Channel: This dropdown box allows the user to select a channel from the dropdown list to modify.
Smart Codec is a function in most Amcrest cameras which aim to reduce bandwidth consumption
without losing visible image quality by intelligently increasing compression where it will not make a
visible difference in the scene.
Type: This dropdown box allows the user to select one of 3 channel types: regular, MD (Motion
Detection), and alarm. Various encode parameters can be for different record types.
Compression: This dropdown box allows the user to select a compression protocol. Most Amcrest NVRs
supports H.264, H.264B, H.264H, and H.265 compression protocols, however, some older models, such
as the 2000 series or below may not support H.265. For more information on H.265 compression, please
refer to section “How to Provide Optimal Performance Using H.265 and Bitrate”.
Resolution: This dropdown box allows the user to set the resolution. The system supports various
resolutions, and they can be selected from this dropdown list.
Frame Rate (FPS): This dropdown box allows the user to select a frame rate. Frame rate settings range
from 1f/s to 25f/s in NTSC mode and 1f/s to 30f/s in PAL mode.
Bit Rate Type: This dropdown box allows the user to select a bit rate type. The system supports two-bit
rate types: CBR and VBR. In VBR mode, video quality can be set.
Quality: This dropdown menu allows the user to set a quality level for a connected device. The quality
can be adjusted based on the capabilities of a connected device.
I Frame Interval: The interval of time between every two I frames.
