Compressor “feature”: Read-only source drives not accepted


  • In a Compressor job I defined a file on an NTFS drive as source.  That was because I had a file of graded video on that drive which was being used in a Sony Vegas project and I wanted to use FCP’s excellent SmoothCam effect to de-shake that video.  For that Compressor job I defined a destination on a separate drive that was HFS+ hence read/writable by Compressor.


  • Compressor gave an error to the effect that the source drive was not writable hence not a valid destination.  Even though it wasn’t the destination…


  • Sounds like a bug to me!


  • Workaround: copy the source media file from NTFS drive to HFS+ drive and use that as source instead, no other change.  Worked fine (apart from wasting my time and disk space).
