Hi, I'm making a video with two rainy sound sources and music sound sources.

I set all the volume and sound settings and it works well in preview.

but the problem is, after I render the video, sound goes awful.

when the volume of music is slowly smaller, (when the song is going start or end)

the volume of rainy sound becoming louder.

and when the song volume finally get loud enough, the rainy sound get smaller again, which I've never set like that.

So to figure out what the problem was, I rendered audio(to .wav), and video(to .mp4(h.264)) separately.

And I found the audio file(.wav) works well even after rendering, when the audio doesn't have video.

But the volume(mixing) issue happens again when I render the two files (audio.wav and video.mp4) together.

Again, there's no problems at all in previews.

Have you tried a different video player for your export?

Yess, it's my player (Potplayer)... MediaMonkey and Windows Mediaplayer play correctly!

Chances are you've got a Normalize effect turned on in the Media Player.

Thank you so much! I'll try setting the effect on the player I use the most!!
