Hello again!

Maybe you know it, but the other day I started to upload videos in my Youtube channel. I want to use Synthesia, but the volume in the videos is very low. I record my screen. After that I use the Movie Maker to add the text... but when I export the video, the volume is very low! And I can't increase it.

Do you know what can I do to solve this problem? I tried with some ideas but I can't fix it T.T

You could record the audio separately so the the audio can rendered with a nice vst instrument while retaining the synthesia effect. Many people who post synthesia videos on youtube do this.

Yes, I tried to do that: I use the same software to obtain, the MIDI and the MP3, and I tried to mix them with the addecuate volume, but the Movie Maker always reduces the volume in the video T.T

Do you know another way to mix and synchronize the video with the MP3?

I just took quick look so I might be wrong
When clicking on the music, music tools will appear and under it will be options.
There seems to be a volume button there.

I saw that button, but the volumen is set at max. And when I play it at the Movie Maker it sounds good. But when I export it (I'm doing it at 720p) the volume is reduced T.T
