The problem always occurs when AMA linked to one or more files of H.264 material usually from a Canon DSLR or GoPro. So I'm guessing the QT mov container has something to do with it. I'm typically transcode/consolidating the material to XDCAM HD 50Mbits. Doesn't matter if material is native to the project or not, it almost always occurs if the clip is over 10 minutes long. I never have any problems with shorter material. I can successfully Import the material at the same settings but if AMA link files, then transcode it fails 95% of the time.
This is really annoying me. Anyone else experience this and have a better work around then the Import function? Or know what I could be doing to avoid this error and still AMA link?
