    Hi,
    I have recently had to export XDCAM MXF op-1a for a tv program. Just got note that the program has been rejected because of many video errors that were like tape clogs.

    I am thinking I should now export DNxHD and take these files to a major post production house and get them to deal with the exporting.

    Has anyone had problems exporting from avid to MXF OP-1a and has anyone any ideas how I can get these episodes to the broadcaster asap without errors?

    Thank you
    Justin

    What codec are you using when exporting? Without something more descriptive than “tape clogs” it is hard to tell if it is a render error, an mpeg encode error (depending on codec), etc. I would suggest trying a video mixdown to the delivery codec required, then try exporting again.

    Thanks Michael,
    I did do video mixdowns with the resolution XDCAM HD 50Mbits MXF then exported to XDCAM MXF Op-1a. I had many crashes because of USB 3 conflicts, this is what Avid support said. I did get it to output to my c drive and thought everything was ok but recieved a rejection from channel 7 in australia.

    All i was told that the files had severe vision faults that look like severe head clogs. And a few other severe vision faults.

    Is this a common problem?

    I read coming out of Avid in DNxHD is like coming out raw from the time line, so I hope these faults arent included in these files.

    Cheers.

    What does it look like when you AMA link your export back into the project? Load into the source monitor, gang it to your original timeline and see if you can see what they are claiming.

    This is the fault, it’s not in the timeline when played back but is in the file output.

    This is how it looks in the timeline.

    Is there a mix of interlace and progressive material?

    No it was all shot on the same camera as progressive

    Hmmm…. Seems like an export bug in the MXF OpAtom 1a file. Do you have Adobe Media Encoder by chance?

    I’m even getting the same errors with a DNxHD output
