Premiere won't export convolution reverb audio effect
Premiere won't export convolution reverb audio effect. When I use Reverb (Obsolete), Audio effect exports fine.
Version 14.2.0 (Build 47)

Still having this issue version 15.4. Surround Reverb FX with "in the church" preset. Sounds good in playback, but the effect is absent in the export. Can anyone please take a look at the project?

This is still a bug (in version 15.2.0), but Matt's solution worked perfectly. Thank you!

Just writing that I am still seeing this as an issue on 14.8.0 (Build 39)
Thank you, Matt
I'm glad I was able to help.
Will write in more details next time :)
Hi Erez, thank you for sending me the project. I never would have figured this out with out it.
I'm going to respond here so anyone else can search for this and see if it helps them find the answer.
I've created a bug for this: DVAAU-4202878
It appears that you were trying to create what is called a reverb tail. There is an issue when rendering the audio, that doesn't appear when simply playing. The nested source, on track A1 of your project, is disabled, I'm assuming to add length to the clip when you nest it into the main sequence. This is fine on playback, but on render, Premiere only take into account the shorter clip on track A2 of the source nest. That is the bug.
As a workaround. In the source nest, readable the clip on track A1, and turn the volume do the clip down to negative infinity. This will properly render, and sound the same.
Again, thanks for the project as I never would have been able to understand this without it, considering the scant explanation of the problem in the original post.
Sorry, I did manage to recreate it.
I've mailed it to you.
Do you need the media?
So I went ahead and duplicated the project so I can delete all the media except for the audio track with the convolution effect in order to send it to you... and of course now the effect exports just fine.
so went back to the original project (with the original media and timeline) - it exports the convolution effect perfectly.
I tried to recreate the bug. no luck.
I knew this would happen.
Can you post a non-client project that shows the error? Or even a screen shot of the effect window running in the problem project? Or send me the project at email@example.com attention, Matt.
The Obsolete Reverb effect is completely different code and should be working. It is irrelevant to any failure in the Convolution Reverb.
Thanks for the very fast reply.
By "won't export" I mean that the file is exporting fine but the convolution effect is missing.
I tried both exporting directly from Premiere and from AME (after reading some forums posts).
I'm on Windows.
I'm not sure I understand what you mean by "seed" but when I play the effect in the project (timeline) it sounds fine, the problem is only in the export.
Again, oddly enough the obsolete reverb exports just fine, so I ended up using it instead.
I also tried restarting the PC and changing the input at "Audio Hardware" settings.
I prefer not to post the project here since it's a client project, but I would happily answer any question you might have.
I just tried the Convolution Reverb and it is working for me on a Stereo clip and Track, and a surround Clip and Track.
When you say "Won't Export" do you mean that Premiere fails to write a rendered file to disk, or that the effects is missing when the export happens?
Are you Exporting directly from Premiere or from AME?
Are you on Mac or Windows?
Convolution Reverb is special, in that it uses a .WAV file on disk as the seed for the convolution. If Premiere cannot find that seed file, the effect will output silence. There also isn't an error message currently if the seed is missing. You can also use your own .WAV seed files, and they are referenced from their original location. So if you move a project to a new machine and the seed file is not in a location that Premiere expects, the effect will not work.
If you post your .prproj, I can investigate.
