Hi there // I'm exporting to New Zealand television and they require the following:
FILE SPECIFICATION. XDCAM HD422 1080i50 Container Format MXF Format Profile OP-1A Format Settings Closed/Complete Timecode Track Present Timecode Start 00:58:24:00 Video PID 2 Audio PIDs 3-10 Video Essence Format MPEG2 Video Format Settings Wrapping Frame Format Profile 4:2:2@High Format Settings GOP (M=3, N=12) Bit Rate Mode Constant Bit Rate 50 Mbps Width 1920 Height 1080 Display Aspect Ratio 16:9 Frame Rate 25fps Scan Type Interlaced Scan Order Top Field First Bit Depth 8 bits Colour Matrix BT.709 Essence Stream Timecode Start 00:58:24:00 Audio Essence Format PCM Format Settings Wrapping Frame AES Bit Rate Mode Constant Channel Grouping Per PID 1 Bit Rate per Mono Track 1152 Kbps Sampling Rate 48 kHz Bit Depth 24 bits
There's a preset in ME under MXF OP1a called XDCAMHD 50 PAL (4:2:2) which I'm ASSUMING will get me close, but I'm assuming. There aren't any options for controlling the bit rate, bit depth, GOP settings.
There is a checkbox to "Force Fixed-Length GOPs" but then when checked, there aren't any options to actually set the length of the GOP, so again, I'm guessing at what I'm getting. I'm sure it will all be fine for the export, but I don't actually know what I'm getting.
There are GOP settings in the MPEG2 container, but I can't control anything in MXF OP1a.
