Thanks to both of you.

Although I’d like to also mention that I’m not sure my cluster is working correctly. All of my computers say “Idle” in the “Shared Computers” preference section (with my cluster selected on the left) – so I’m not sure what that means. I know the current computer I’m on is transcoding (because I see the progress bar), and that machine is also listed as Idle, so maybe they are all working?

Cool Martyn!

I’m not sure regarding CPU usage. I’m currently encoding a proRes into an h264 mp4 on a 5 computer cluster, and my CPU usage on my main machine (the one I’m typing on) is at 270.5% (I think out of a possible 400%, 4 cores?)

However, some of my transcodes did fail unfortunately.

Any ideas on this?

or this:

Thank you James, that worked! Compressor is actually working now – seemingly normally. Martyn I hope it works for you…

Thanks James.

I did find: /Library/Application Support/Apple Qmaster/

I deleted the folder.

However, before I did that, I tried running Compressor again, and got this message:

I got the same message after deleting that Qmaster folder as well.

Then, I deleted Compressor.app and re-downloaded from the App Store. Same message. Very confused.

The two different encodes I’ve tried were using the following settings:

1280×720 h264 MOV, 3000kbps, 128kbps AAC

and

960×540 h264 mp4, 750lbps, 128kbps AAC

Both are custom settings that I made.

Thanks Martyn. I do not, nor ever had, Qmaster and its preferences pane installed. (I briefly tried experimenting with Qmaster using the old compressor, but don’t remember having a preferences pane in system prefs or anything like that.) I may have just contradicted myself – but I definitely didn’t separately install Qmaster with the old Compressor.

Regardless, it may be totally unrelated.
