I have created a video with a few different video clips and some effects. When I preview it, it sounds fine, but just one of the videos keeps having issues with the sound, I don't have any effects applied to the sound, but after rendering it cuts in and out a few times before coming on. (I do have the clip fading in using Opacity, but have that for other clips too with no issue). I've been experimenting with different codecs and formats, but all seem to have the issue! Help!
I'll bet it's the codecs of your source footage that is causing the problem. Tell us what they are. All of 'em.
Actually I solved it by rendering using Adobe Media Encoder instead of rendering in Adobe After Effects. Worked like a charm! So that's my advice for anyone
