Hello. I have found some similar threads about crackling sounds in exported videos, but none that addresses my exact problem.
I get an annoying crackling in the exported video when I use a source video that I have previously converted to a fixed frame rate using Shotcut and then insert a cut. The crackling does not occur when I use the original mp4 source video with variable frame rate inserting a cut, and it does not occur when I use the converted video without inserting a cut.
A workaround I have found that seems to work is creating a new audio track and copying the audio from the video track. Even if I do that after inserting a cut on the video, this will result in an exported video without crackling.
Is this known somehow and can I do anything about it?
