Compressor 4.1

Thanks Frank, that did it!

I skipped trashing the files and did a clean install. Compressor opens up normally. No surprise there.

Now to test my workflow and hopefully get my main system updated. BruceX benchmark saw about 20% improvement from mtn Lion and FCPX 10.0.9 to Mavericks and FCPX 10.1 on this MBP (exporting Prores not h.264). Impressive.

Same problem here with Matrox compressHD ver 4 I literally had to remove all instances of Compressor, the App, the Preferences the Compressor folder in Applications Support then reboot and reinstall to get it to work. Runs fine now, but Matrox says they are working on a version 4.1 for Mavericks but their Mountain Lion version is incompatible with OS 10.9

I am having the same, serious issues.

I have troubleshot the whole system up and down. I went as far as doing a complete disk whipe and starting with a clean Mavericks install. After that I did nothing but download compressor 4.1 from the App store and sure enough the whole system freezes up when I launch Compressor.

I am running Mavericks 10.9.1 on a 2009 Quad Core MacPro with32GB RAM. Everything is running great, even FCPX 10.1 is running better than the previous versions.

I seems like this is something only Apple can fix….?

Repair Disk Permissions. Create New Admin account and test there.
That’ll confirm whether it’s a user or system issue.
I do think that maybe Compressor is having issues creating it’s own default directories. Please read my previous post.

I have done both, repaired, removed, created, removed… again, a complete, clean Mavericks install from scratch should do it, you would think?

I am not having any compressor issues on my MacbookPro at all.

When I start compressor on my MacPro I will see the logo and the both displays will flicker black in the bottom third of the screen for a split second. After that either Compressor will remain at the splash screen or the interface will come up, but all distorted…

No. not if the issue isn’t OS related and I don’t think it is.

That sounds like it may be GPU related.
Try pulling one monitors and rebooting.

I believe I have a work around that is allowing me to use both Compressor 4.1 and the Matrox compressHD card.

I went and deleted all of the preference files and move all of the Application Support files to my desktop for safe keeping, and deleted and reinstalled 4.1 so it was as clean of an install as I could make it. Then, rather than trying to install the old Matrox presets, I created a new custom preset in Compressor. In the Video -> Quicktime settings section, I chose Matrox MAX h.264 as my codec.

Voila! My new preset is now working like a champ using the Matrox compressor. I’ve encoded several files, testing with and without, and it is definitely working! Encodes are taking place in ~real-time, as they were before the upgrade.

It is annoying that all the old presets don’t work, but at least this is a bit of a work around that seems to be solid until Matrox updates their product.

hope it’s not gosh to post here, but Larry jordan has a good explanation on why older MacPros are having trouble with the new Compressor. Seems it wasn’t written for older processors.

What he points out is pertinent to new MacPros as well.
Basically i5 and i7 processors use Intel’s QuickSync technology that Compressor 4.1 takes advantage of for hardware acceleration. The MacPros, both old and new don’t have that as it’s not in the Xeon series of chips. That’s why he mentions that a recent i7 iMac may actually encode faster than even a new MacPro on single pass encoding.
