    Media Composer v. 8.2.11 AS02 codec options

    Hi,

    I'm looking for codec options, settings or information about AS02 volumes in Media Composer 8.2.11. I have XDCAM HD material on the timeline, transcoded from AMA sources. In the help there is no mention of XDCAM, but J2K is listed and would of course be much better than eg. DnXHD.

     As far as I understand it, an AS02 volume should be able to use the native mxf essence as long as it is supported in the codec library (which XDCAM is), but the only shim files available are DNXHD profiles - so on commit of the AS02 volume, Media Composer 8.2.11 transcodes XDCAM HD essence into DnXHD - which is not what I want. It's pretty pointless, takes a very long time to export, and is really just a waste of space.

    EDIT: Found the shim profiles for J2K - and I'm using that, but still would like to know if XDCAM is supported.

    From https://www.avid.com/static/resources/common/documents/AS-02_Whitepaper_9-7_3PM4.pdf

    AS-02 is codec agnostic. So any video essence format that can be wrapped in MXF can also be used as media in AS-02 essence component files. When Avid introduces AS-02 product support, any codec included in Avid’s shared codec library will be supported natively in AS-02 workflows—including Avid DNxHD ® (VC-3), uncompressed, AVC-Intra, and XDCAM HD.

    As per Avid on my avid machines. [view my complete system specs]

    I looked into the manual, and it doesn't mention XDCAM for as-02 export. You could try and create a new shim file for XDCAM from an existing one and see if that works.
