Why can you hear Sound Effects on a hidden Layer in a rendered .MP4 Movie?

1. Here's why

In Build Mode you can hide a Layer with Sounds so that the Sounds will not be heard.

However, when you render a Clip or Movie, any Sounds on Layers that are hidden can still be heard in the rendered Movie.

This is a technical constraint.

 

2. Workarounds

2.1: Consider saving a back-up of your Scene with the Sounds and then temporarily delete the unwanted Sounds before you render the Clip or Movie.

2.2: Alternatively, if the Sounds are the only Sounds in the Clip or Movie, you could render to .MP4. Then in a video editor, remove or replace the sound channel with some other sounds.
