Is your feature request related to a problem? Please describe.

I have troubles with videos that come with a low audio volume. i tried to use custom command to apply a loudnorm filter but it somehow worked only when at the same time remuxing it into an mkv.

Describe the solution you'd like

I wish there would be a simple "normalise audio" checkbox in the Seal settings that saves the video with normalised audio. i know it would require additional processing, but it would make things so much better/easier.
