After transcoding some clips from MXF to ProResLT, the transcoded files sometimes contain black lines throughout the footage. The RAW files do not have these lines so it appears to be an artifact created through the transcoding process. I've re-transcoded this file again with AME and it appears fine. We usually go back to the RAW footage when finishing an edit but want to make sure the proxies are rendering properly as well.
The clips are being transcoded off an external USB3.0 drive on a Mac Pro 2015 Can, with mid-range specs.
Thanks,
