PRX Encoder Overview. Imagine communications Nexio Global Proxy 3.5

The Nexio Global Proxy 3.5 is a software application for the Nexio AMP media platform. It allows the Nexio server to generate low-resolution H.264 MP4 proxy files simultaneously while high-resolution video is being recorded. These proxy files are saved to any standard storage array where they can be viewed, edited and conformed back to high-resolution. The PRX Encoder application can monitor up to four Nexio AMP high-resolution record channels. When it detects a recording, it creates a low-res proxy file on a storage device that you designate. The PRX Encoder runs in the background. The PRX Encoder Client displays the current status of each recording channel to which it has been configured. All MP4 proxy files created by PRX Encoder can be viewed via Nexio Player or Nexio MediaBase plug-in (NXMB).

PRX Encoder Overview

Nexio® PRX Encoder is an optional software application for the Nexio AMP media platform. It allows the

Nexio server to generate low-resolution H.264 MP4 proxy files simultaneously while high-resolution video is being recorded. These proxy files are saved to any standard storage array where they can be viewed, edited and conformed back to high-resolution. PRX Encoder does the following:



Encodes Nexio video to H.264 proxy at 384 kbps, 768 kbps, 1.5 Mbps, or 3 Mbps



Encodes Nexio audio to ACC at 32 to 192 kbps per pair at 22000, 24000, 41000, or 48000 kHz, 16-bit.



Encodes HD Nexio content at 640x360 proxy resolution.



Encodes SD Nexio content at 640x360 (16:9) or 480x360 (4:3) proxy resolution.



Encodes up to four channels simultaneously in real time.



Creates MP4 file format.



Encodes all Nexio-supported HD and SD formats.

The PRX Encoder application can monitor up to four Nexio AMP high-resolution record channels. When it detects a recording, it creates a low-res proxy file on a storage device that you designate.

Configure the Encoder

PRX Encoder Overview

You can use the Nexio Config software tool to configure your server to work with the PRX Encoder.

On the

Channel Configuration

tab, the

Record/Bi-directional Channels

value indicates the number of record channels available on the server. You can set a

Low Res Proxy Channels

value for each record channel up to a maximum of four channels. PRX Encoder will use these channels to encode the low-res proxy files.

For example:



If you have 1 record channel on your server, you can specify 1 low-res proxy channel.

If you have 4 record channels on your server, you can specify 4 low-res proxy channels.

Be sure to configure the Video Bitrate, Audio Bitrate, Audio Sample Rate, and GPRX Location.
