I have premiere elements 14.
My movie was filmed in several places with different volumes.
Is there a command that makes the same sound level throughout the movie ?
There is no automatic command for this.
However, if you open the Audio Mixer (under the Tools menu), you can monitor your levels and ensure that they peak between -6 and zero. And you can adjust the levels for each video clip by raising and lowering the yellow "rubber band" that runs through each clip.
Don't trust your ears or your computer speakers. Use the Audio Mixer to ensure you are accurately monitoring your audio levels.
Thank a lot for youe immedialy answer.
