Question. I just finished creating a video in Premiere Pro CC. I export the video, and I notice that at every video transition, there is feedback for about 5 seconds. I tried exporting the video to different video formats, exporting the audio by itself (issue persists). Any ideas on what might be going on?
We can't know. You have not provided any info about your project, your video sources, what transitions you used, your exact render settings, audio mix details, how you review and verify your output and whatnot. You need to be much more specific. Ask in the Premiere forum and provide all those details.
