Audio bug repeating in every cut

[korax1989]

I have a video footage from a conference. The source video is about an hour long and I cut it down to some three minutes, highlighting the most interesting things the speaker said. Nothing unusual. 

The recording is in two files which I am putting together in a sequence. In that sequence, I am also adding a denoise effect and a dereverb effect. This works fine. 

The problem: I am inserting the source sequence into another sequence where I'm doing the cuts. Whenever I make a cut, the cut point includes an audio bug. Imagine the speaker is saying "So" somewhere, and the first split-second from that is in every cut. In the instant of the cut, there's a split-second (maybe 2-5 frames long) of audio that doesn't belong there. This also happens when I just play the sequence from somewhere manually. 

Note that this happens only in the target sequence, not in the source sequence. I have tried transcoding the video files to another format, I tried another PC, but it still behaves the same. The behavior only goes away when I remove the denoise and dereverb effects.

Does anyone have a clue what could be the problem?

sounds like you added sound FX to the source sequence... then you put into 2nd sequence as you whittle down your edits to individual cuts ( maybe finesse it in 2nd sequence so your clips start and end exactly where you want ).  But when you make cuts in the 2nd sequence you get the weird stuff.

How about if you do your cuts and move stuff to 2nd sequence, finish your finesse stuff, then nest the 2nd sequence and add sound FX to the second sequence when all else is done.

Many thanks, that helped 🙂 

Off topic, but maybe you'll know about that too - I can see the sound curves in the original sequence but it's a completely flat line in the target sequence. This happens to me a lot in Premiere. Do you have any guess what could be the cause?

The Denoise effect has been know to behave badly after edits are made to a clip.

Do as salvo34 suggested.
