    AMT uploaded of AVCI - decode issues

    Hi,

     

    Have used AMT to write to mxf files some precoded AVCI as the latest AMT release no longer includes AVCI compression. In media composer it decodees as per the attached screen shot.

     

    Any ideas, nornally media works or does, not, in other tools decodees as a full frame

     

    I not eform looking at the generated MXF thta an Access unit delimiter is present  but the SPS/PPS seem to go missing. Avid generated media has "00 00 00 01 06" NAL's that seem undocumented.

     

    Is there more detail about the precise layout of AVCI expected available

     

    David
