I haave a bunch of mp4's for which the sound is too soft. I would like to import, normalized, increase db by 12, and save to an mp4 or avi (a file type that Mac and Windows computer users both could view.)
Is there a way to do this with a batch file?
I am currently using Premiere Elements 7, but could upgrade if necessary.
There is no batch way to do this in Premiere Elements -- or any program that I'm aware of.
But if you start a new Premiere Elements 11 project, you can place all of the videos on your timeline, right-click and select Audio Gain to Normalize one clip -- then, right-click and Copy that clip, select the other clips all at once, right-click and select Paste Effects and Adjustments.
There is a similar ways to do this in other versions of the program, but only version 11 is designed to interface well with MP4s.
Another method, that might be useful, would be to use the Audio Mixer to increase the Volume of the entire Audio Track, and all Clips on it. Now, that is ONLY an increase in Volume, and is not Normalization.
