I have a composite shot, where I use the audio effects noise reduction and large room on the same audio track. When both are activated, the whole sound of this shot begins to stutter like a heavy fast tremolo and also the video playback is suddenly slow and stuttering. So I can only use one effect at the time to get a proper preview. In the exported file is everything fine. Then both audio effects work nice together.
Is this a general issue with the noise reduction?
At this point, I work around by switching noise reduction on, when I want to export the file.
