Encoder - Output

Unlike inputs, the output settings are the same for all Encoders, regardless of how the program was ingested into MIP.

Table: Video Output Profile

Video codec:

Pulldown to specify how MIP encodes the program for storage. MIP supports: H264, WMV3, WMVA, and WVC1.

Bitrate (Kbps):

Pulldown to specify program bitrate for storage.


Pulldown to specify screen resolution for storage.

Compression Quality

Force minimum GOP size:

Optional field to set MPEG Group of Picture structure. The setting defines how many frames are dependent on the preceding frame before another I frame. MPEG not only removes redundancy, spatially within a frame, but temporally among frames. I frames, known as the key frame, is the only frame that can be decompressed without reference to other frames.

Reduce frame rate

Reduces frame rate to reduce output bandwidth consumption.

Reduce frame rate target FPS:

Output frame rate value.

Table: Audio Output Profile

Audio codec type:

Pulldown to specify how MIP encodes audio for storage: AAC, WMA and WMApro. When configuring the Audio CODEC type which describes the audio CODEC used by this encoder it will change the COCEC for each of the audio streams in the feed.


Allows you to create multiple audio outputs.


Pulldown to select output type: AAC, WMA9, WMA9pro.


Audio is encoded as variable bit rate VBR). This field sets the upper limit even if the source material results in a higher instantaneous value.

Sample. rate

This field accepts values from 8,000 – 96,000, recommend value is 48,000 samples per second.


Scales the resulting output, normalized to 1 dB.


Number of audio channels to encode the output, typically 2 channels stereo. Maximum is 48.


When alerting is checked for a specific audio stream it enables alerts for that stream if Alerts are configured for the encoder. Unchecking this option inhibits alerts for this stream. This is typically used if the audio stream does not actually contain audio.

Live stream is used to view low latency video on a monitor page. Note: this feature is CPU intensive.

Sub Encoders

Each Encoder has a primary video codec that creates the channel stream digital multimedia archive. If desired, additional sub encoders may be configured. Sub-encoders are typically set for lower resolution and bit rate, in comparison to the primary codec that serves specific monitoring or file exchange requirements.

Sub-encoders have the same server requirements as the identical setting for the primary codec sequentially; CPU cycles are needed for the compression engine and disk storage for the resulting file.
