Mini Guide: Normalizing Audio for Multiple AVI files

[Nologic]

The MP4box command line should look like so:

mp4box.exe -add "E:\Test\This Is - Michael Jackson.mpg" -new "E:\Test\Complete\This Is - Michael Jackson.mp4"

Which simply adds the video & audio streams from the MPG container to an MP4 container. This doesn't apply Replay Gain or re-encode the video or audio streams at all.

[Belini]

The problem seems to be that you mention it, tested it on windows7 with the command that I passed and file was created in XP that is giving the problem did not create the file, would have any way to fix this? Can I use any dll or codec to mp4box not use the XP files or use another program instead of MP4BOX?

[Nologic]

hmm works fine on WinXP for me.

You can create MP4 containers with FFMpeg...but I've ran into issues in the past...that is why I use MP4Box.

I did notice your WinXP install was Service Pack 2...and it should be version 3...however that shouldn't make any difference at all in this.

[Belini]

Here also works in XP with spack2 my computer I use it more codec's various programs and install it in a new installation of XP without putting any codec does not work, MP4BOX need to have other things installed on windows to run?

If possible do the test using the Video Gain a fresh install of windows to see if we give the same problem that gave here.

[Belini]

I discovered that generated the error, without Visual C++ does not convert to MP4.

Note: If you want to test just uninstall Visual C++ and use the video gain to normalize and save to MP4

[Belini]

great changes have you made ​​@ nologic, downloaded to test.

[Belini]

What command line returns the duration in milliseconds of the file?

Some audio files that I do not show the correct duration.

Download: http://www.4shared.com/rar/IbfmoV7F/Audio.html
- Right duration 4:13
- Duration returned 19:57

[Nologic]

I don't have a membership at that site...so can't download.

Anyways under "; Define Count & Content For Audio Streams" an array is built which the element that holds the value is $Array_Audio[6][1] which is in seconds...so anything after the decimal would be milliseconds.

You can also use FFProbe directly to find out.

ffprobe.exe -show_streams "<FilePath>\<TestFile.EXT>"

Oh something that might be making it into the next version:



Might make it easier telling where things are in a batch.

[Belini]

Nologic Thanks helped me a lot, the new version will be very good with this function.

[Nologic]

New Version 1.33

Updated FFMpeg
Added x264 10bit
Enabled selecting between FFMpeg, x264 8bit and x264 10bit
Added Progresbar's...still needs some tweaking

Note:
10bit encoding should only be used if you are looking to preserve high color depth from something like a Blu-Ray.

[Belini]

@ Nologic, thanks again for sharing your work.

[Nologic]

New Version 1.34

Minor update...tweaked the progressbar's a bit...still need more work on them.
Updated FFMpeg
Updated MKVToolsNix

At first this was working for me. But now the files go through the process, complete saying no errors, then files in the complete folder are not 89dB or even close, mostly between 82-85. I encoded most of my videos using AutoGk for AVI, and Handbrake for MP4.

[Nologic]

@ jd185051 -

Sorry for the late reply jd185051, it can sometimes drop that low...but it shouldn't be constant. You can encode most vid's with this...if you want H264 & AAC...if you want to use other codec's...then the others are far better picks.

@ Everyone -

http://www.mediafire...a6lrafiro59p081

This build switches from Nero AAC to QAAC (Apple), which improves quality and nips some error's in the butt.

Next build will likely start making use of MediaInfo as a replacement for FFProbe...as FFProbe has been to problematic and it's causing some issues that I'd like to have resolved.

The build after that will likely be adopting EBU R128 as a replacement for Replay Gain (AAC Gain).

Ideally after all this, things should be more stable and more consistent.

[Belini]

@ nologic, thanks again for improvements made.

[Belini]

@Nologic, You forgot the test message on line 1050: MsgBox (0, 'test 1', $ Array_Audio [6] [1])

[Nologic]

Ah thanks for the catch.

I also noticed I had Qaac values enabled but was using FHGaacEnc for AAC encoding...this would be wrong...set everything to Qaac.

[Belini]

Thanks for posting this update, I will do tests here.

[Nologic]

New build:

Fixes Exit button on Progress Dialog to actually kill all processes related to Video Gain.
Added Label on Progress Dialog to make the user aware of what file is being processed.
Added Minimize to System Tray to both Video Gain & Progress Dialog's.
Now TrayTips should only be visible when the Progress Dialog is minimized to the System Tray.
Added Portable Unlocker, to resolve files being locked in the Temp folder...thus screwing things up.

I am trying this for the first time. Wow! From what I am seeing so far, this could very well be used as a Benchmark tool. It is about 45 minutes into its process and it has both my cores maxed out to a point I can not do anything else until it gets done. Just thought I would through this out there so you know. This is probably something you might want to run at night or when you don't plan on using your computer for a couple of hours.

[Nologic]

I'll see about adding the ability to set how many cores are used, and the priority they are ran at.

No idea when the features will land...I'm kind of all over the place far as when I release and what's contained in the release.

But the source code is available, so you can jump in and tweak things your self...AutoIt isn't very scary...everything is done via command line with tool chain...so no scary API's to deal with.

[phlibby]

It worked GREAT. If I can get the time, I would like to see if I can bring myself up to speed and help out. You guys are way ahead of me right now. The most I can do is tweak the batch files to get them to work for me. I used the AVI_GAIN_SOOPA_LOUD to bring up the voice levels and bring down the over amped action sounds in an avi. It worked better than I hoped for. Thanks Guys. You are geniuses!

How to normalize the peaks? Or on your volume, and not only 89 decibels.

[Nologic]

There isn't anything currently in the app that does this...you could look into using SoX...if you can come up with a working command line I'll show you how to integrate it into the script.

[Art Blos]

Sorry, but I'm a user, not a developer. And I was hoping that "Video Gain" will normalize the peaks without climbing on the command line and scripts. You can add this feature to the program?

Generally I have a couple of suggestions about the program

[Art Blos]

I forgot to say the most important thing - many thanks for that at least someone thought to develop such a program. In RuNet it has long been looking for, but I found it would seem. This is almost exactly what I needed.

But it should be further developed, in which direction I want to advise.

[Nologic]

I'll look into it...but no time line on when it might appear. Keep in mind all I'm doing is gluing app's together...I'm not doing any hardcore development.

[Art Blos]

Well, at least that.

And who is responsible for the major changes in the design?

[Nologic]

The top of the food chain is Soopafresh, since it was he that started this whole thing. I've changed a substantial amount of it, discarding some of what Soopafresh did, but enhancing other stuff that he made. You can think of VideoGain as a fork of AviGain...then there is Belini who has made a number of changes and enhancements based off of my fork...some of his changes I've brought back into my fork of the code.

So all of us are responsible for our own code bases...however I'm fairly sure that Soopafresh is the one that knows audio better than the rest of us.

Maybe PM him on how to go about it, and maybe from his answer I'll integrate such changes into my fork...but this is a bit of a hobby project...so I add things as I feel like it, and as time allows.

Right now on my to-do list is:
Boosting Voice channels like what Soopafresh did in one of this scripts
Expanding support for AC3
Being able to set process priority
Being able to set number of CPU cores
Basic Video stream down sizing
Basic watermarks
Swapping out AACGain for R128Gain
Better MetaData handling
Better attachment handling (none at present)
And maybe your audio peek normalization...if I can find out more about it.

Hell there are probably other things I've forgotten about...might even pull in more of Belini changes.

So who knows what I'll add next...or when....if ever.
