Lightroom 4.1 RC gets stuck every time I try to export any video. For some reason it tries to load and validate all my Audio Units plugins (I'm an audio guy and have hundreds of audio plugins on my computer). But the Audio Units don't succsesfully load, they freeze in the background and I have to restart my computer to get them to go away. I can't force quit or anything.

Why should Lightroom have anything to do with my Audio Units plugins? Is there a way to bypass them entirely? I never plan on using lightroom for anything audio related ever. I've even tried temporarily disabling them all by moving them out of the active plugins folder, but it somehow still finds them and tries to validate them.

What sort of files are you exporting? What options do you have in the export preset?

AU validation is bound to the OS, so something related to the container or codec (whichever makes most sense) is triggering that. Because it never finishes, one of those plugins is still marked unvalidated the next time around it is triggered.

Remember that Lr is just asking the OS to handle the request for video playback.

Your best bet is to work from the container/codec in question and see what tends to the common trigger.


By any chance are these videos trying to open up in VLC?

Ah I suppose that makes sense. Yeah I'm just trying to edit footage from my Canon 60D (.mov files, 1080/30, H.264 I believe). It's not launching VLC or anything.

I've realized that it was hanging on the AU validation because I have all my iLok and syncrosoft license keys at my recording studio, but I do all my video work here at home. Wish there was a way around the AU validation thing, because I rarely bring those keys home. Would hate to have to lug them back and forth each time just to tweak color.

Does final cut or premiere go through that same validation process? They've never given me any trouble before.

Thanks for your help!
