I wonder if someone can assist me. I have Premier Elements 11 and I can export from within Premier trimmed MP4 video clips (videos created from my digital video camera) to my hard-drive in any format without a problem. When though I attempt to export other sourced MP4 video clips (created via my screen capture software called Movavi Video) it fails to export the sound, vision yes, but no sound or maybe occasionally a buzz on sound. Any ideas what the issue might be?
This is likely related to the audio and video codecs Movavi is using.
Open a sample of the video from Movavi in a program like G Spot or Media Info and note the resolution, frame rate and, above all, the audio and video codecs listed.
