Apple Compressor still cannot deal with XAVC-S or MXF files from Sony A7RII and FS5

Compressor 4.3.2, the current one, cannot open A7RII MP4 files.

It has no clue with FS5 MXF footage either and transcodes to an all black/empty file.

OK, mmhm, how long has this Sony codec been out again? Is this another codec war Sony and Apple are waging?

Short of using Sony's Catalyst software, you have Adobe Media Encoder and EditReady that can transcode your Sony footage to Prores on a Mac.

Good luck.
