*About SMPTE RDD-9 compliance:
Depending on the manufacturer, MXF files exported directly from editing systems may not fully comply with SMPTE RDD-9, and there have been reports of such files being rejected by broadcasters’ equipment (see the URL below). For this reason, MXF files hardware-encoded on a Sony XDCAM deck (PDW-F1600) are the most reliable option.

To date, there have been no reports of broadcasters rejecting MXF files exported directly from Grass Valley EDIUS Pro 8 (8.5), EDIUS Pro 9 (9.5) or AVID Media Composer (AVID TRMG 3.01).
Materials in other formats (including HDCAM masters) can be accepted after individual consultation. Please contact the Cape Advanced TV sales team and support desk below:
