When it comes to video editing softs -- even the light duty ones -- I remain something of a clumsy neophyte, so take that into consideration re my numerical ratings. This comment is to note that (as best I can determine) AVIdemux 2.6.1 was the last to be offered in a portable version. And that is a terrible pity. @kodec (Comments post #4) -- No, I don't think you are missing anything. It appears to me that some important functionality has indeed been stripped away from this program over time, and that is not a good thing either. Format options and other things that used to be there are no longer. So I'm going to hang onto the 2.5.x and 2.6.x portable versions. I'd rather have a program that (sort of) worked sometimes, under the right conditions, than a tool that kept on under development but was hobbled.

EXCELLENT program used it for years, thank you to developers.
SUBJECT: script engine
Problem: not loading, not saving filters nor projects.
Reason: ??? could be i'm using such an old compu'r (XP)
FIX: Took out (cut) 268s scriptEngines FIRST,(placed into a blank folder) in case i wanted to place it back. Then installed version 267s "scriptEngines" folder

Thanks, jerghal, that's it! And I already thought I was hallucinating about something that never had existed. The 2.5.6 is the final version as far as I'm concerned ;-) I cannot recommended it enough to anyone who wants to cut xvid avi.

I found that for cutting Xvid/Divx avi's you best use 2.5.6 (which I do) and for cutting x264 MKV/MP4's 2.6.X is best suited. 2.6.X indeed crashes a lot on avi's.

Am I missing something or this tool has lost most of its functionality over the years? I remember options for intelligent frame cutting even on non keyframes. It did all without problems etc and now all those fine options are gone I think, all that's left is a toll that crashes. What was that old version that last worked nicely with all those frame cutting options asking and automatic repair?

No other program can do lossless editing on so many different containers anbd codecs like this app can. My only wish would be to include wmv / asf support as i still have to use the old asfbinmaster for that.

Have been using freemake's video converter for mp4->flv. While the video quality was good (except for the initial video frames which was very chunky)I just used the latest avidemux for the same purpose - the quality is noticeably better - especially wrt initial frames.

Hi AviDemux Author, Thanks for the Program. It does what I need to do.

I use your Portable x32 and I wonder if you can add a feature so the program can remember the "Last Folder" used ... everytime I want to save a simple 2 second job it takes me back to the Root of your Program.

G!:)

Avidemux is a superb video encoding program but lacks some features that I desire on Handbrake, such as MKV encoding with chapters and optional subtitles.

I like working with Avidemux but for trimming video there are multiple problems. Cut MKV files sometimes have audio out of sync or have video but no audio. Cut FLV files work OK with some players but with others the video is speeded up or won't play at all. Version 2.6.0 is more reliable than previous versions but still needs work. If I have trouble with AVIDEMUX I try FREE VIDEO DUB for cutting and that usually works OK.

For years I have been using another program for converting my DVDs into DivX files, and I keep the original AC3 audio stream for surround sound. But my brother ran into a snag recently - in trying to add one of the videos to his Zune, its software rejected the video every time. Turns out his Zune doesn't like AC3 audio - probably because his Zune is a dinosaur. I didn't want to have to re-encode the whole thing from scratch, so I immediately thought of this program. Using avidemux I was able to keep the DivX video stream, and convert the audio from AC3 to MP3. The whole process took only 20 minutes for a 2-hour movie, where redoing it from the start would have taken over 2 hours, not counting the time it would have taken to re-rip the DVD.

Just downloaded version 2.5.6 and looking forward to trying it out.

Does not work with WMV3 at all.

I have Windows 7. Basically there is no audio output (sound) in the trimmed output video file. The input wmv file I have is WMV3 video (4CC codec) and WMA version 2 audio. The output audio stream is bad.

When I played the input wmv3 video in avidemux, it played very slowly, and the audio sound was sharp broken.

WMV editing needs major fixing for it to work.

I went back to v2.5.3 and it does not work in Windows 7 either. No sound output in the edited output video.

If you have troubles running this with Mac OS X Lion (10.7x), follow these steps:

1. Right-click on Avidemux icon and select 'Show Package Contents'
2. Open folder 'Contents' --> Open folder 'Resources' --> Open folder 'lib'
3. Move or Delete 2 files: 'libiconv.2.dylib' and 'libxml2.2.dylib'

Happy New Year!!!
Thanks for the updates.

Regarding audioencoder_aften.cpp
i guess, there is no need for the bitrate lower than 160k for ac-3
request to authorts to add 448k and 640 k for ac-3

diaMenuEntry bitrateM[]={
{56, "56"},{64 ,"64"},{80, "80"},{96, "96"},{112, "112"},{128, "128"},
{160, "160"},{192, "192"},{224, "224"},{384, "384"}
};

request to author to modify it to

diaMenuEntry bitrateM[]={
{160, "160"},{192, "192"},{224, "224"},{384, "384"},{448, "448"},{640, "640"}
};

Avidemux is indeed a nice creation.

I wanted to rip the audio from an MP4 video with AAC audio. I marked my regions, but having to stop the preview to mark them was inconvenient. Then saved the audio with the ‘copy’ option, which didn’t seem to produce valid audio output and neither did the ‘PCM’ option (I assumed that it was exporting WAV format). Fortunately, I am an easy guy to please so the MP3 format which does work was good enough for me!

Monkeypack's comment leaves me a bit confused. First of all, the x86 ("32 bit" )version of Avidemux - as is almost always true - will run without issue on x86-64 platforms. I've run it on both Vista 64 and Windows 7 64 without issue. Avidemux does not depend on external libraries; the installer packs everything you need (though you can of course install Avisynth as well if you want to use the AVS Proxy with or without the AVSProxy GUI). A failure to install where others have had success using an identical installer (such as the numerous people who use each installer put together by Lord_Mulder or others) typically indicates a problem with one's own PC. It is of course possible that you either had an improperly compiled installer or (more likely, and fairly common) that some interruption in your internet connection truncated your download of the installer.

If a fresh download of the installer (SVN latest, please) from Lord_Mulder's site or Razorbyte's site doesn't resolve this issue, suspect something with your own PC.

As far as "Rumored to be super fast", Avidemux is as fast as the decoding and encoding libraries it uses and the options you select as far as encode complexity. Any speed advantage otherwise derived by Avidemux probably points to poor coding by developers on other GUI projects.

Giving this a poor grade because I couldn't even get it to launch.
Actually downloaded and installed the 32bit version first and the interface looked extremely simple to use. I was excited. But nothing happened when I tried to start the conversion -- quickly I realized I needed 64 bit version. So I uninstalled 32bit and installed 64bit version. It goes all the way through to the last step of installation, when it's supposed to launch, and it crashes. I tried re-installing several times and always crashed. Looked around for help on this issue and couldn't find it. Seems like if you can get it to work for you, it's a good tool. Because the interface is so easy, and because it's RUMORED to be super fast, I'd definitely give it a try. If it works for you, congrats. But don't be surprised if it doesn't.

This software is the Best. I use it to create DVD from DVR recorded programs. I also use it to fix screen ratio problem. I am using version 2.5.2 because the codecs in the new version don't work with the software I have, Pinnacle Studio 12, and DVDLab Pro 2.0 otherwise I would upgrade (tried but had many issues). So everyone is complaining about AV sync issues, well guess what it is not AVIDEMUX causing the issue. If you don't believe me then that is for you to research, because I have researched it. I found this out most computer CPU's over 1.5 Ghz can handle audio and video with very limited issues, if the codec is present the software player finds the codec it decodes and plays that simple. But when edit there is a piece that is put into the mix that we don't see or even think about. You see the Audio and Video when recorded has AV sync issues already, they are just masked by the decoder and sound driver and HW layer. Now as you increase the CPU speed you also increase the bus speed. This in turn also increases the interface card bus frequency. Thus a unnoticeable AV sync now become more noticeable. Using Encoding and Decoding software only further increases the problem. So the solution. You see audio is in terms frequency base and shifting or adjusting any frequency when dealing with audio cans induce harmonics that we cannot detect or even realize that they are there. And when coupled to video which has a high frequency can also cause this inducing factor. Okay so you are wondering what the solution is right?

Okay here it is.

Most sound card manufactures use a shift sample in the input stage of the sound-card and then use a de-sampling frequency in the output. In most cases this is not audible to use and can be masked by the sound driver and HW Layer, this includes all on board sound chips, and most low end sound cards. I have corrected my AV sync issue by using 2 sound-cards, one is a legacy card that does not have the input shift sample (Creative Sound Blaster 16 PCI original CT4430) and the the second is a Realtek HD on board sound-card. Now the trick, in BIOS you have and option to set the PCI clock for each card on the PCI bus, most are set to Auto 32 CLK. With the Sound Blaster in PCI slot A. I set the bus CLK to 16 and remove auto and set the freq for that bus to be 16MHz all other are set to the default by using the Auto and record the setting and then manually entering the setting. It takes awhile to get all if you have multiple PCI cards. Once done set the default audio to Sound Blaster and your done. I use Media Player Classic and use it the output to the Realtek HD audio through pin configuration. And I have tried the with version AVIDemux 2.5.2, 2.5.3, 2.5.4 and will test with 2.5.5. This does not get rid of the AV sync you never will it just allows the software to handle and mask it better.

Avidemux is an excellent program but it has some issues with A/V sync.

Regarding the A/V sync issues with MPG/VOB files, try this trick: first load one of these files on VirtualDub then go to File > File Information and check the Skew value. Usually it's a negative number (like -510 ms). Open the same file on Avidemux and input this number on Shift inputbox, before saving the file.

It worked for some files.
