Hi folks,
I'm trying to find a tool that will allow me to amplify the volume in AVI files. The problem is that when I convert my AVI files to DVD-Player compatible discs, the volume is quite low. You can hear it, but it is nevertheless still bothersome.
Any suggestions on what tools can do this?

The Amplify() function of AVISynth will do this. Your script will look something like this:
Code:avisource("d:\Path\To\Your.avi") amplify(2.0)
CogoSWSDSOld ICBM Coordinates: 39 45' 0.0224" N 89 43' 1.7548" W. New coordinates: 39 47' 48.0" N 89 38' 35.7548" W. -
That sounds great. However. Does AVISynth have a GUI? Is there even an EXE for it? I checked the install folder and there are just some DLL's, and Uninstaller, and docs. Weird. In the Start Menu, it's pretty much the same thing - no shortcut to an exe of any kind. I'm confused.

Not as fast as AVIsynth, but VirtualDub Mod or the regular VD has a function in the audio section to boost volume levels. You can frameserve from them directly to a MPEG encoder.
I use VD Mod and filter or edit DV in it by adding the Panasonic DV Codec. Then I save out the audio as a WAV with full audio processing after adjusting the audio level, if needed, and convert that to AC3 with ffmpeggui. I frameserve just the edited video to TMPGEnc encoder and encode video only. I add the AC3 in with the encoded MPEG-2 video during authoring with TMPGEnc DVD Author.
If you need to do more work on the audio, the freeware audio editor Audacity will accept WAV audio and you can filter or modify the audio as wanted, output as a WAV and use ffmpeggui afterwards. -

Process an entire directory if you wish, but start off with a single AVI file and see if you're satisfied with the results. -
Hi again guys,
It sounds like the AviSynth solution put forward above is what I need. I appreciate your other suggestions, but I'm not looking for normalization or other processes requiring specific AVI stream formats. I've tried the Virtual Dub suggestions as well, but it doesn't like the files I have (XVid). Additionally, I don't want to export the audio stream and amplify it manually since this carries the risk of desynchronizing the audio with the video when re-imported.
The problem with AviSynth is that I cannot figure out how to execute any scripts!!! There doesn't appear to be any kind of GUI or executable program available to process script commands on video files! I just don't get it!! How is AviSynth suppossed to be used if all it consists of is a few DLLs and HTML files??!! Aside from AVSEdit, I'm not aware of any additional apps I need.
HELP?
