    nablet XAVC XDCAM Plug-Version 4.5.5

    PLAYBACK ISSUES USING THIS PLUGIN, or even earlier 4.03 with Media Composer 2018.5 running on OS X Sierra. Traschcan with dual AMD FirePro D700 64GB ram

    Fresh install of everything including OS. Media plays back fine in Premiere, VLC and Catalyst browse etc.. In fact if I simply rewrap the mxf clip with video container switcher avid will link and play it perfectly as well. Already sent support request to nablet. just wondering if any one else had this issue.

    Re: nablet XAVC XDCAM Plug-Version 4.5.5


    I got a case going.... at least support can try it and see if it happens.  Are you able to upgrade to 2018.7.1 or 2018.8 so we can eliminate any playback engine issues?????

    The people @Nablet got back to me. They have confirmed the issue to some extent:

    "We tried to reproduce the problems under same Media Composer version and and OS version. When playing back the linked file we can see some clitches at the beginning of the clip but not as many as in you screenshot. Indeed there are problems.
    But when we link the file with the MC builtin MXF plugin we see the glitches as well. This tells us that the issue is caused by the MC internal AVC decoder. The nablet plugin acts as a so called Samplemapper only under MC. This means it only provides access to the compressed video data and meta data and the decoding is processed inside MC. There is nothing we can do at nablet side to fix the issue.

    However, we then installed MC 2018.8 and found that the problems are gone with this version of MC. So you should update to 2018.8 to overcome the problems., if possible."

    However I think it is important to note that the exact same file, when rewrapped in a quicktime container, plays back perfectly. I highly doubt it is a decoding problem, but rather it is probably incorrect metadata being passed to media composer.
    I am a bit reluctant to upgrade to 18.5 since a number of people have claimed to roll back to it for reasons of stability.

    I had the exact same problem. I cleared the AMA cache files. That did the trick for me. Fingers crossed.
