I am noting that in the upper left "source" panel of Premiere Pro, audio and video files generally sound fine. I am noticing that when I put them on the timeline I get quite a lot of "s" hiss. DeEsser doesn't do anything. As well, narration that I record in Audition sounds fine there but ends up with the same problem in the timeline. I have just started using this lately so am not sure what problem I have. Is the timeline representative of the final audio quality or is it just a quick and dirty working area? If so then then the "source" would be more accurate.
So far, I have:
Please advise. I am on a deadline! Thanks,
Close PPro. Delete the projects preview files. Reopen the project and see if the problem persists after it renders new ones.
If it's still there, and since your have a deadline, render a few seconds of a problem area as a test. If it's not present in the final output, then it's a non-issue.
Thanks. Tried rendering and final product is clean.
