Net-X-Copy - Create, Convert & Proxy

verifycc icon

Net-X-Copy is part of the Net-X-Code server and Net-X-Convert/Proxy workstation software. It is designed to convert audio/video/media files to proxy or broadcast/post files, mix audio, extract metadata, and create one or more jpeg preview images.  It can also embed captions into output files like MXF and MOV, and replace the audio or video tracks of a source file during conversion. This article contains the Linux/OS-X/Windows command line API for this tool.

Net-X-Copy (Convert/Proxy)

Net-X-Copy is a command line interface to the copy engine used in Net-X-Code, Net-X-Convert, Net-X-Proxy and videoQC's export feature.  It can be used for a number of file extraction and conversion functions including clipping, proxy generation, metadata extraction and partial file restore.  All these conversions are also available for our REST API.  Some examples of typical command lines follow:

Basic conversion

NetXCopy -s <sourcefile> -t <targetfile> [-a <ackfile>] -p <profile>

Proxy Conversion

NetXCopy -s <sourcefile> -t <targetfile> -p mp4-h264

Proxy Conversion With Parameters

NetXCopy -s <sourcefile> -t <targetfile> -p mp4-h264 -width 640 -height 288 -h26xprofile high -h26xlevel 51 -gopsize 30 -kilobitrate 4000

HLS ABR Proxy Conversion

NetXCopy -s <sourcefile> -p <targetfile> -p HLS-TS-Multibitrate

DASH ABR Proxy Conversion

NetXCopy -s <sourcefile> -p <targetfile> -p HLS-TS-Multibitrate

Export XDCam With Embedded Captions

NetXCopy -s <sourcefile> -t <targetfile>.mxf -p mxf-sonyhd -cc <alternatecaptions>.mcc

Metadata Extraction

NetXCopy -s <sourcefile> -t <sourcefile>.xmp -m

Single JPG Frame Extraction
