Exporting The Animation & Sound Editing

Hello,

I was looking for how to export the animation as a video file that I made in AnyPortrait. I'm currently want to use this feature for sound editing in the video editor software. Because it is easier to do it since I'm better at video editor softwares such as Premiere Pro, After Effects or Audition. I'm going to make a sound editing for a whole animation, and then render as .mp3 or .wav then re-import to Unity to use in the game. Probably it would better if I create new Gameobject for sounds since I have multiple animation clips in one portrait.

Or is there better/easier solution for sound editing inside Unity without exporting the animation as video file? I'm open to suggestions.

Also I might be use this video export feature for not only game animation creation, maybe other things as well such as wallpaper animation etc...

Thanks.
