    ProRes Import and Conslidate woes- Audio Static in ProRes clips

    Running Media Composer 8.8.1 on a windows 7pro workstation (details below). The DP shot XAVC HD clips on a Sony FS7 but the network requires that we convert all the raw clips to ProRes 422. The final piece also needs to be delivered in that format, so  I figured I would also bring the ProRes clips into avid and edit in that format. 

    I used a third party program to convert the XAVC files into ProRes 422, and upon playback there is no video or audio issue with the converted files. I then first tried fast importing these into AVID, but once the file was imported I would get "Core Consistency Check Failure" in the source monitor. Alternately, I successfully AMA linked to the ProRes files (which also look and sound fine- so there is no issue with the original converter) and then conslidated them to a new media drive. This seemed to work, except I'm noticing a problem with the second audio channel. Consistently, there is a multi-frame loud static blip that comes up throughout all the clips at random intervals. This is a problem across all the consolidated media. I can't seem to figure out why. Any thoughts?

    For anyone else that has seen this issue- it seems I neglected to choose to convert the clip's sample rate to the project's. Turns out, the source clips were 44khz. Choosing to make them 48khz removed the static issue.

    Unfortunaltey, the problem didn't go away as I thought. It just switched the static issue from channel 2 to channel 1.. Even if ProRes isn't supported by AVID for PC, it's still a strange issue. I'll just have to edit in AVC and deal with it for deliverables.
