I have few movies in avi form, and their volume is really low.
I have to switch my play control and wave to maximum output, and then i can hear the movie's audio.
How do I increase the volume of the original avi file?
Full Version: Increase the volume.
hmm...you could try demuxing the audio part, convert it into wave and normalise the volume to a more acceptable level, reencode the file, and mux it all back together. 
If the audio is MP3, you could losslessly adjust the volume with MP3gain after demuxing, no need to re-encode.
Get VirtualDubMod, load the AVI, click Streams -> Stream list. Select the MP3 stream (if there is one), click Demux to extract it. Maximise it with MP3Gain, then disable the existing audio stream in the AVI (by clicking Disable in VDubMod), click Add, select the adjusted MP3 file, click OK, and save. And make sure "Direct Stream Copy" is selected in the Video menu.
No time to get into more details now, just post again if you have problems.
