Encoder: Output

Unlike inputs, the output settings are the same for all encoders, regardless of how the program is ingested into Volicon Media Intelligence service.

Table: Video output profile

Video codec

Dropdown used to specify how Volicon Media Intelligence service encodes the program for storage; Volicon Media Intelligence service supporting H264, WMV3, WMVA and WVC1

Bitrate (Kbps)

Dropdown used to specify program bitrate for storage

Resolution

Dropdown used to specify screen resolution for storage

Compression quality

Force minimum GOP size

Optional field to set MPEG group of picture structure; setting defines amount of frames dependent on preceding frame before another I frame; MPEG removes redundancy spatially within a frame and temporally among frames; I frame (or key frame) - 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

Dropdown used to specify how Volicon Media Intelligence service encodes audio for storage: AAC, WMA and WMApro; when configuring audio codec type that describes the audio codec used by this encoder, codec changed for each audio stream in feed

Audio languages

Specifies one or more audio channels
Table: Live stream profile

Enable

Live stream used to view low-latency video on monitor page; note that this feature 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 bitrate, 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 is needed for the resulting file.
