Compressor is "unable to connect to background process."

I'm working with Compressor 2.1. After I drag my video into the Batch window and appy a preset, nothing happens except that a message pops up saying "Cannot Submit Batch. Unable to connect to background process."


I don't know what that means. Can anyone tell me how to get Compressor to work?

Mac OS X (10.5.8), 8 GB of RAM

OK, I followed those directions to the letter

, removed all the files it told me to, re-installed Compressor from the original disks, and the only result is that Compressor now quits before even opening up.


In other words, when I double-click on the Compressor icon, the startup window appears for several seconds (the picture of a vise) and then it vanishes and a message comes up saying "Compressor quit unexpectedly." If I hit the "relaunch" button. the same thing happens.


So, I thought maybe I missed something in the instructions, and I carefully removed, once again, every item from the Library and from the Applications folder that it instructs you to do, and then once again I re-installed Compressor from the original disks.


And once again Compressor crashes on launch.


Anybody got any idea why this is happening?

I repeated purging the hard drive of Compressor and its supporting files, and once again reinstalled Compressor from the original FCP disks, and the second time it worked, there were updates from Apple, I applied them, and now, finally, Compressor works.


Now I can use Compressor to try to solve the original problem: how to upload a 3.5 gig 25-minute video to YouTube that was created in Final Cut Pro (YouTube allows up to 20-gig uploads).


To repeat, six months ago I created a nearly identical video to this one, compressed it moderately in QuickTime Conversion, and it uploaded to YouTube just fine. it looks good, and is still there being watched every day.


But I can't repeat that success this time. Time and time again I have compressed this video in various ways during export from FCP, through QT Conversion, and every time I try to upload it to YouTube, it gets stuck at some point during the upload.


So, I decided to try Compressor instead. One of Compressor's settings resulted in about a 200 MB file that did upload to YouTube, but when it appeared on their website it was a mess, full of pixillation and had no sound, so I deleted it. The search for successful compression settings continues.


I sent an e-mail to YouTube's help staff, and received a reply that Safari is an "unsupported browser" and that I should try to upload using Firefox, Explorer, or Chrome instead. I don't have Explorer but I did try Firefox and Chrome, with no more success than Safari. I sent them back a question: why do you not support Safari, a browser in use on millions of Macs? What has YouTube got against Safari?


Anyway, if anyone has had success sending large video files to YouTube, I'd be glad to know what compression settings you used, and whether you did the compression with QuickTime or Compressor.
