New audio with no change to the video

[derekworld]

I'm trying to change out the audio on a video that was previously rendered and tried with various export settings including matching the source, maximum render quality...etc, but I'm getting video artifacts with the export. Is there a way to replace the audio and keep the video exactly the same on export?

I would take the video into my timeline. Hold down alt or option and click on the audio to select just the audio and delete it. Then take your new audio into the time-line and re-export.

Thanks! Yeah I knew that part but was having problems with video rendering artifacts.

I finally tried the UHD Youtube setting and it worked as expected.
