Audacity does not handle video, so if you want to process the sound in Audacity then you need to use a video application to put the processed sound back into the video.
Audacity can extract the audio content from many types of video file if you have ffmpeg installed:

To even out the volume level in a track you use "dynamic range compression" (often just called "compression").
Audacity includes a dynamic compression effect:
