Hey there, I have a huge project file for an 18min video I'm working on, and everytime I open or close premiere my audio filters (highpass & denoiser) disappear every-time I re-open the file with this error message.

When I click on the clip, in effect controls, where the filter should be it says "Offline (filter unavailable)"

Then I have to go through dozens of clips and re-add them each time I want to render.

Anyone else have this problem or know how to fix it?

I've never encountered this but it appears Premiere can't find the files. Look in Premiere>support files> and see if audiofilters.dll is present...or if it has somehow become un-registered --- did you do anything to your registry lately? There is a regsvr32 function you can use with Windows Command Processor-- google for info --- to re-register .dll files that windows doesn't recognize, if that is the case. Would be odd and rare, but that could cause the problem...

If you are SURE that is the problem, there is information here: http://support.microsoft.com/kb/249873 This support article is headlined WInXP but applies to all subsequent versions as well. Be careful!

Hmm, thanks, it looked like there was not a folder exactly called support files, but there was an audiofilters.dll in the main folder.

I wonder if this has something to do with upgrading from Cs5.

My apology, in CS6 the audio dlls are no longer in the support file. There are 4 dll files beginning with audio in the Premiere CS6 root directory --- AudioFilterHost, AudioFilters, AudioRenderer, AudioSupport. For all I know, there may be other files that affect the audio, but these are the obvious ones. My understanding is that the upgrades don't overlap with the new version, and shouldn't interfere but I'm reaching the limits of my experience on this and don't want to mislead....bottom line is, it is apparent that CS6 is not finding the filters for some reason, and the dll registry problem is the only cause I can think of. Which is not to say that there are not others, of course!

One thought occurs, the directory in your clip looks odd, what is the "\\?\" before the F: locator? Never saw that before, could it be a clue?

Hmm, thank battle.

The odd thing is that the filters work fine, until I close and re-open the file.

Anyone else run into this?
