I'm having an audio issue when exporting from Premiere Pro 5.5. I have a number of clips that I've used the Multiband Compressor on. Some audio clips are straight cuts with no gaps, some have a 3-frame cross fade. When playing back in Premiere everything sounds fine. When I export the sequence the audio drops out for about a frame in between each audio clip which contains the Multiband Compressor effect. This occurs no matter what codec used during export, and when only audio is exported.
I had a similar issue yesterday with the DeNoiser. Rendering didn't help but selecting the clips and going to Clip > Audio Options > Render and Replace fixed the issue for me.
I have the same problem. EXACTLY. I thought I became crazy, but not. What a pity, because Multiband Compressor is really impressive for a lot of situation, especially when there is voice.
