export : MXF and TC issues
on Jun 6, 2016 at 2:39:49 pm

Hello,

One MXF export doesn't pass the QC of the broadcaster, with this two errors:
  • TC discontinuity (infringement of SMPTE 377-1)
  • mismatch between essence TC (SMPTE328M) and wrapper TC (infringement of EBU R122 specs)


Metadatas shows two TC in wrapper : MXF (Material Package) and SMPTE TC, at 10:00:00:00
Further, in video stream (essence (Elementary Stream) TC) :
Time code of first frame : 00:00:00:00

AVProbe (FFProbe's fork) results :
[mxf @ 0x102b400] Unknown frame layout type: 1
Input #0, mxf, from '/media/NAS-3/MEDIACENTER/TRAVAUX_CLIENTS_IQ/TF1/_Exports/1098308.mxf':

And AVConv :
$avconv -v error -i file.mxf -f null -
[mpeg2video @ 0x1c2d220] warning: first frame is no keyframe
file.mxf Operation not permitted

(last line is just Unix translate of output code)


There is no this issue on the ProRes source.


Context :
  • MXF XDCAM HD 422 1080i50
  • from ProRes HQ 1080p25
  • AME (Adobe Media Encoder) 8 (CC 2014) & 9 (CC 2015)
  • MediaInfo


TC break fixed with a new souce.

How to match the TC ? Or how to remove Elementary stream TC ?
In AME, there is no settings for this.

Thanks.
