After Effects warning: Couldn’t open Quicktime video output component

[Sean Mccormick]

I do have quicktime yes 7.5.5. And i looked it up in the preferences and it wasn’t enabled. So i enabled it and it is still doing it.

Hello,
your same problem…

The last thing I’ve installed is “Noise Industries – FxFactory” tools.
This “DOESN’T” mean this is the cause, it’s just to know if you recently perform the same installation. If so, maybe this could be the origin of this problem.

Best reguards,

Ok, I solved the problem, from what it may concern to my machine:

“Noise Industries – FxFactory” tools are OK. No problem with them.

I read on a post on another forum about a person with the same issue.
The answerer suggetsted him to remove the Matorox MX02 (that he uses, and I use too – do you too?) from the quick time folder in the library folder (not the “user/library” but the root of your drive library folder).
The same could happend with Blackmagic Multibridge card too.
I did, problem solved… but what about my MX02 now..?

I put back that files (3 files) inside the “library/quick time” folder and I get a look to matrox… it was unplugged!!!
I accidentally unplugged the cable under my table with my foot…

If this can help you…
I must apologize with Noise Industries.

Best reguards.

So i still haven’t fixed the problem. I go to the render queue after i did a simple time remap in my AE cs3, and i do everything correct, i check the audio box so when it renders i have the audio and i push “render” and it doesn’t process and all. the progress bar doesn’t move even to 1 percent. But if i uncheck the box with no audio it works perfect. I need the audio or else it is a pointless effects for me. I downloaded the trial version of AE cs4 and it worked fine. I used to have AE 7 and it worked fine than as well. But i only have AE cs3 now and it wont work. Please help.

For what it’s worth, I just encountered this problem on my machine after removing a Black Magic Decklink card. Per what Stefano did, I went into LibraryQuicktime and removed the Blackmagic component out of there. Once I did that, AE worked fine without the error.

Maybe remove and replace individual codecs there to isolate the problem?

I had the same problem.
I have an AJA IO HD and used it to output the video preview to an HD monitor when I worked with After Effects.

My solution:
In After Effects I went in Preferences/Video Preview and changed the Output Device to what ever I want to use when not the AJA IO HD – that fixed it for me.

Wow – that really helped. I had an AJA card taken out of my Mac Pro this morning and the that Quicktime error kept coming up when I opened After Effects. I went into Library > Quicktime and deleted the AJA components and the issue is gone. Thanks so much!

I had the same problem with AE after swapping out my capture card. Was using a Kona3 card and swapped it out for a Blackmagic Decklink Extreme 2. Seems that it was still trying to reference some of the presets from the Kona card which no longer existed. Went into the QT Library folder, deleted those, no problems. Thanks for the help guys.

Hi i think this will solve your problem;
1 Download WinRar
2 Go to your downloads and open ‘QuiclTimeInstaller’ with WinRar (Right click on ‘QuickTimeInstaller’ find WinRar option and choose open with winRar)
3 Then the WinRar screen will pop up. Right click on the screen and choose Repair archive (Alt+R)
4 And done!

I had the same problem and solve it the easiest way. No downloads, no winrar, no nothing.
The fact is that i had a Blackmagic card unplugged from the computer and my video preview preferences were still pointing to that inexistent card in the system. I pointed that preference to “computer monitor” and voila…no anoying message anymore…
