Thanks LoRd_MuldeR, but that is for XviD. I need it for x264... They are different from what I can tell. :)

Quantization Matrices for H.264 look like this:
http://forum.doom9.org/showthread.php?t=96298

So I think the GUI from the screenshot is suitable for x264.
It only needs the Combobox, which is grayed out on the screenshot, to choose one of those values:
4X4_LUMA, 4X4_CHROMAU, 4X4_CHROMAV, 8X8_LUMA
For 4x4 matrices, the unnecessary Edit Fileds need to be grayed out, of course.

// EDIT

Maybe it would be usefull if you also add a button to load a matrix from file.

New Avidemux 2.4 SVN build for Win32:
http://fixounet.free.fr/avidemux/win32/2.4_r2796_win32.zip

This one should include the new Preview dialog.

I have no idea where or what I got this x264 screen capture from. But if someone can tell me where that is from from, it would be very helpful. The custom matrix window is the only part of the new x264 update I am not finished with. :(

I just do not want to do it wrong...

Hi, SadaraX
I think this screenshot is from the x264 GTK+ encoder.

Hmm, not sure if I can compile that, but I might try.

Wow, the forum is still down? I thought it was just a bad day, I have been super busy for the last two weeks and I have not stopped by to see what is wrong.

News from the Avidemux homepage:

No, I got it and I compiled it successfully. Damn, I really wish I had known about that GTK GUI sooner, it would have saved me a LOT of time....

Every time my compile scripts recompile Avidemux, they also check and recompile x264. :)

I just noticed that there's a huge difference in Video Quality between Avidemux and VirtualDub!
In Avidemux the same video looks much worse than in VirtualDub :(

Do you have post processing disabled in both of them?

Otherwise you are going to have talk with Mean.

I know there is an issue (not sure if it is a bug) in the color systems, which I have pointed out (I even pin-pointed the problem source file).

I know there is an issue (not sure if it is a bug) in the color systems, which I have pointed out (I even pin-pointed the problem source file).

There no filters used in both applications and Avidemux's post-processing is completely disabled.
Doesn't seem to me that it's a color problem. The file exported from Avidemux to VDub doesn't show any difference in color, but still the quality is worse. Seems to be either a MPEG-2 decoder problem or the video is "filtered" in some way it shouldn't...

I just noticed that there's a huge difference in Video Quality between Avidemux and VirtualDub!
In Avidemux the same video looks much worse than in VirtualDub :(

Here are two screenshots that clearly show the difference:
http://img527.imageshack.us/img527/3768/videovdubla4.png
http://img527.imageshack.us/img527/4151/videoadmbt5.png

Especially have a look at her hair and at the frame in the background.

The input file is a MPEG-2 file, captured from analog TV.
In both applications it's the exactly same input file and the same frame!
No filters enabled, no resize. Just the unchanged original video.

// EDIT

Here is another test:

Once the video directly from MPEG-2 input file:
http://img506.imageshack.us/img506/3327/capvduboj8.png
And now the video as exported (lossless, unprocessed) from Avidemux:
http://img506.imageshack.us/img506/3018/capadmyo4.png

Both shots taken in VirtualDub.
Again quality much worse in the video that was exported from Avidemux!

Okay, I have checked with AviSynth now instead of VirtualDub-MPEG2, and it's getting even more strange!

When I use DGIndex to create the .d2v file, the video looks the same as directly imported in VirtualDub-MPEG2 - very few chroma artifacts.
But when I make an AviSynth script with MPEG2Source(<path to .d2v>) and open in VirtualDub, it suddenly looks like in Avidemux - more chroma artifacts!

Nevertheless colors in Avidemux still are very different from anything I've seen in VirtualDub...

There seems to be a problem with Avidemux.org

I get this "Lecture/Envoi d'emails" site, instead of Avidemux homepage.

The previous build was broken, this one seems to work fore me :D

Quick note: the previous problems reported about x264-in-mp4 and so on are at least partially solved (I'm encoding x264+aac in mp4 right now, and it seems to be working again).

Edit:
All these output combinations work perfectly now:
- xvid+mp3 in MP4
- xvid+aac in MP4
- x264+mp3 in MP4
- x264+aac in MP4.

This is just such a great news !

Avidemux 2.4 Revision 2814
First install r2811_win32.zip (http://fixounet.free.fr/avidemux/win32/r2811_win32.zip), then update to r2814.zip (http://fixounet.free.fr/avidemux/win32/r2814.zip) :)

This update is a quick fix for the "Median 5x5" filter. Very nice to clean Chroma Noise from analog material!
Also the video is displayed at the right position now, when "SDL Accelerated" is selected for Video output.

// EDIT

DarkZell666, I got a question: Do your "x264+mp3 in MP4" files play properly in *all* players?
I did a quick test an the result was, that it played 100% fine in MPlayer, but MPC didn't play any sound :(
For the test I used latest MPC build, latest ffdshow-tryouts and latest Haalli Splitter.
Nevertheless "x264+faac in MP4" didn't show such problems ...

// EDIT²

I have reported the problem in detail:
http://www.avidemux.org/admForum/viewtopic.php?pid=17066#p17066

LoRd_MuldeR

12th February 2007, 22:12

It seems that the "objectTypeIndication" is the problem with mp3 audio in MP4 and Avidemux!

Avidemux uses an objectTypeIndication of 107, while MP4Box will use 105.
Haali's Splitter doesn't recognize the objectTypeIndication of 105 for some reason.

Works 100% fine with MPlayer and VLC Media Player...

I know there are some translations of Avidemux into some languages. I believe J.M. does a few of them. Let me see...

On my system Avidemux is available in French, Spanish, Klingon (that my be a joke, but the file is there), Russian, and Czech (I think).

No, but everyone does not speak English.

Of course you are right.

But most commands you need to know in Avidemux are simple words like "Open", "Append", "Save" and so on. Even if you don't speak English at all, you should be able to cope with that. Especially if you worked with similar tools before. And don't forget that English is still the "default" language in Computer Science. I doubt you will get far without English in this profession...

Anyway, problem seems to be solved now *g*

I've been playing with AVIDemux by encoding to the PSP Full Res format and I really like how easy it is to do this.

What I don't like though is that all the videos are tagged with "Avidemux" as the name of the video.

Can some tag editing features be added to the program please? Just some way to choose the filename as the tag/title of the video would be fine with me.

Also, is there a way to script the Auto -> PSP Full Res settings? I'd like to just make scripts for the Custom menu with appropriate names to match what I want done. Like "PSP Full Res 100MB" "PSP Full Res 1000Kbps" and just change the x264 settings.

Right now in order to do what I want I have to go to the Auto menu and select PSP Full Res then press OK. Then I have to load my custom x264 settings.

I just want to be able to go to Custom -> My Custom Setting and have it all done in one step.

Wow, he finished making the PSP stuff work? I thought that was going to be broken for a while... heh, I guess I missed stuff when the Avidemux forums were down.

I have no idea what is causing that, because i have never used it. But I will have a look in a while, you might get better results by asking on the Avidemux forums.

In the 2 or 3 most recent builds, using vorbis causes the encoding to stall at the beginning (crashing Avidemux). Opening the calculator also crashes AviDemux with a c++ error in audioencoder_vorbis.cpp @ line 124. (Other audio formats don't suffer this problem).

I'll try the latest builds more in depth, but there's always a setting or another that isn't saved on exit. Actually, the "save preferences on exit" setting isn't saved, so I wouldn't be surprised if that had something to do with it :p
**Edit: DAMN CAT !!! It climbed on the keyboard while I was finishing something else and I hadn't finished writing my post ...*

The vorbis problem doesn't seem to always happen. Btw I've just opened an xvid+mp3 avi with packed bitstream. I unpacked it, and I can't reencode the video because the video codec combobox is grayed, and locked on "Copy".
***Re-edit: the video codec combobox only grays when I choose "avi, unp. vop" or "avi, Pack vop" output formats. Is it normal ?
***Re-edit again: the vorbis encoder crash only happens once I saved my work as a project or if I re-load the project I've just saved. Otherwise it doesn't crash (and other formats still don't have the problem, so "project+vorbis" is no go ATM).

LoRd_MuldeR

4th March 2007, 12:46

The vcodec combobox must be grayed when "avi, unp. vop" or "avi, Pack vop" is selected, because in this mode Avidemux will pack/unpack the bitstream. This cannot be done at the same time as the encoding. If you have a packed bitstream AVI, you must first unpack it and then use then load unpacked file to do the work. Afterwards you can re-pack if you need to...

About the "project+vorbis" bug: I think if you send a bug report to Mean, he will be able to fix it. I guess it's the project file which is either not written or read properly. Maybe you should send your project file too.

I don't know how (un)packing worked in older versions, since I never do that. Maybe older versions just did not prevent improper usage of "avi, unp. vop" or "avi, Pack vop". Might also be possible that the latest changes to the (un)pack code make a difference...

I don't really understand the purpos of pack or unpack bitstream !

Could someone explain it to me, I look here and there but don't get it ?

PS: When avidemux ask me if I want to unpack, I always say no since the file saved is still playeable...

Well, "packed bitstream" has something to with the way the different Frame types (I-Frames, P-Frames and B-Frames) are stored in the AVI file. In packed AVI's several frames are packed together into one "big" frame and dummy frames are inserted to keep the number of frames. Later the decoder will unpack those packed frames and display each frame at the correct time, the dummy frames will just be skipped. So while a normal AVI will have frames stored like this "1-2-3-4-5", a packed AVI will contain "p-d-d-d-d" where p is the packed frame that contains all the frames from 1 to 5 and the d's are dummy frames. When reading a normal AVI, the decoder will read frame 1 from the AVI file, then display frame 1, then read frame 2 from the AVI, then display frame 2, then read frame 3 from the AVI, then display frame 3 and so on. With packed bitstream the deocoder will read a "packed" frame from the AVI and thus get a bunch of frames at the same time (for example all frames from 1 to 5). Of course the decoder will display only the first of those frames, the rest will be kept in memory. When the next "dummy" frame is ready form the AVI, the decoder will discard the dummy frame and instead display one of the frames that are already in memory. This is done until all of the frames in memory have been displayed. Then another "packed" frame is read from the AVI, followed by a series of dummy frames. And so on. I hope you understand. It's a little bit confusing.

Packed bitstream is a "hack" introduced by DivX in order to workaround a limitation in the VfW interface (VirtualDub). It was needed to support B-Frames, because VfW isn't suitable for B-Frames. Packed bitstream is ugly and it's to be avoided at all costs! Nevertheless sometimes you have packed AVI's (for example AVI's made with VirtualDub/DivX) and want to edit them. In this case "unpacking" is required before editing in Avidemux...
