I ned to change locations, and I'm working from a MacBook Pro with an extrenal drive containing my FCPX project that was "Shared to Compressor." If I do the following, does Compressor truly resume the job (pick up where it left off), or does processing start over from the beginning?


  • Pause the submitted job
  • Quit app
  • Eject & disconnect external drive
  • Sleep the machine
  • Wake
  • Connect drive and wait until it mounts
  • Launch Compressor 4
  • Resume job


Thank you!

    Pausing/resuming the job: That depends on the codec your encoding too. For example, encoding to h.264, no, encoding to MPEG-2, yes the job will resume.


    As for your other examples, you need to start the job over.

    Thank you, David. I didn't realize different encoding jobs would react differently to pausing.


    Here are two of my experiences, if anyone needs the info:


    1. Compressor is running, and working on an encoding job (a FCPX project on external drive with its own power supply).
    2. Unplug all cables from MacBook Pro, except FW800 to external drive.
    3. Put MacBook  to sleep by closing it (do not  pause the encoding job).
    4. Wait for MacBook to fully enter sleep mode (LED on front begins pulsing).
    5. Turn the external drive off.
    6. Unplug the FW800 cable.
    7. Move the system to a different location.
    8. Turn external drive on (not connected to MacBook yet)
    9. Wait for drive to spin up and get itself ready.
    10. Plug drive's FW800 cable into sleeping MacBook.
    11. Wake MacBook by opening it.


    During my MPEG-2 encoding, this did not work. The job would not resume (it got hung up)  and I had to start over.


    During a Quicktime encoding, it worked perfectly. The job continued processing once the system emerged from sleep mode.
