    C300 MarkII 10bit MPEG 50 Mbps wont consolidate

    We have shot 1080p23.976 on the C300 Mark II at 50Mbps (Mpeg2) Canon XF codec at 10 bit.

    On MC 8.6.2 (and also the older 8.5.3)  - Used the latest AMA plugin and the AMA plugin a version back - both will link and play the footage fine, however, consolidating does not work - it creates a series of errors, prompting "An error has occured" then a "Structured exception" error.

    When shot at 8 bit on the C300 regular (mark I ?), the footage consolidates fine, so I think it is the new 10 bit flavour of the MarkII that is the issue.

    Is 10 bit unsupported for consolidating?  A lack of support is not mentioned on the "Avid Supported Video File Formats" document that ships with 8.6 in the knowledge base - that document says XF codec is Natively Editable.  Nonetheless, I know the camera is sort of new. 

    Consolidating is everything to our workflow.  Transcoding is a deal-breaker, and I know that works, so please just let me know if there is anything I can do to make this consolidate.

    I´m not sure if Avid suports XDCAM HD50 with 10Bit. The Material I get from the newer Mark II is most of the times 8 Bit.

    Hey Kao -

     

    Heads up the C300 mark II only shoots 10 bit in 1920x1080 422 50Mbps.   See attached image.

    8 bit is relegated to the mark I.  The Mark II is also MPEG-4 AVC/H.264, whereas the Mark I records in 8 Bit MPEG-2 Long GOP.

    Different codec. Avid currently sees it via linking (with Canon's plugin) but cannot consilidate the 50Mbps media from the Mark II - per an Avid tech response I got. However, I have had luck consolidating 1920x1080 from the Mark II recorded at 160Mbps intra frame (default on the Mark II), thought Avid doesn't like that material when exporting a QT reference file to Squeeze.

    Update - the newer versioin of Media Composer reports the codec coming from the Mk2 differently than the older versions of MC.  It now correctly identifies it as XAVC-L, which is clearly not supported yet.  The XAVC-I is supported, but is a minimum of 3x larger. 

    I had originally assumed that it was XDCAM or MPEG2 because the C300 mk1 uses that codec for its Long GOP recording option at 50Mbps, and it was labeled as XF codec (same as this codec was labeled in older versions of MC).

    The C300 Mk2 records at XAVC-L 50Mbps, which is supposed to be about twice the quality of the XDCAM50/MPEG2 50Mbps that the C300 Mk1 shot.  

    I hope this XAVC-L codec is supported for native edit in the next large release of MC.  The size would be more ideal for the kinds of footage-heavy shooting we are doing than the larger all I-frame codecs.
