Enhance the volume level of your videos. Work with such common formats as FLV, MPG, WMV, and MP4. Modify the default audio volume incrementation in decibels, change the output directory and file naming patterns, manage notifications and shutdown options.

Free Video Volume Booster can help you solve the problems you face when you intend to play a video file and its volume is just too low. In this respect, the program can boost the volume to the desired level without altering the rest of the video. Luckily, it supports most video formats, like AVI, DIVX, XVID, MPEG, MPG, MKV, RM, RMVB, FLV, MOV, MP4, ASF and WEBM. It may also happen that your player does not support a given audio codec. In such event, Free Video Volume Booster helps you by letting you use a different codec.

The program is extremely easy to use and there are no hidden features. Although there are some options you can tweak, it generally works fine with the factory presets. Luckily, it can process batches of files and thus save you a lot of effort.

In terms of settings, you will probably find that the possibility of deciding how much you want to boost the audio volume is very convenient. However, remember it supports batches, so it would be good if you could do that for files individually, as not all of them may require the same volume boost. In this respect, it would also be useful that you could preview at least a segment of your video to check if the level you have chosen works for you.

All in all, Free Video Volume Booster does its job well and quite fast. Good news is that it does not alter the original video in any way. Instead, it creates a new instance and saves it to the output folder you have selected. Unfortunately, you will not have many other options to control output, such as automatic volume normalizing and checking replay gains for peaks and lows. This product is free to use, which is always welcomed. Still, it has some ads and encourages donations. You should also know that some players support on-the-fly audio normalizing, which makes this program unnecessary.
