I installed the AVCIntra encoder which allowed me to load .mxf files from my Sony PXW-X70 using XAVC-L 50 format. However the sound is garbled. The sound is clean if I load the same files in Vegas Pro or if I convert the files to Prores and then load in to Video Pro X, so I know it is not the recording. It sounds like a codec issue inside Video Pro X. Does anyone have any ideas or suggestions about this problem? Thanks in advance.
