I have a video that is essentially one person talking, with a crowd of people listening and responding. What I'd like to be able to do is edit out some sections of the speech.
I need to do this in my video editor, because there are three tracks of video synchronized with the audio.
If I just delete sections and then close the gap, that's obviously going to sound wrong.
But how do I smooth out the transitions? is it a simple fade between tracks? Do I overlap them and fade them? Is there a particular technique for this?
Is there a guideline for how long or short the crossover has to be in order to make them seamless or at least not jarring to the human ear?
Please note I am only concerned about the smoothness of the audio transitions. Where the video cuts are made can be covered with other images.
Also, I am using Kdenlive for my video editing.
