I have a video with audio, I do not need the orginal audio track as it is to be replaced with a music sound track. I thought it would be as simple as selecting the wave and deleting but this does not seem to be an option. Please could you let me know how I go about doing this simple task.
And this will remove the audio when you render and output? (i..e remove it from the finished article)
If anything is turned off in the composition window it won't render. It could not be easier. Turn it off, it's gone.
