Posted October 27, 2011 by . Tool version 2.5.3 using OS WinXP
Ease of use 9 of 10 Functionality 8 of 10 Value for money 10 of 10 Overall score 8 of 10


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.

I revisit this program every so often to see if it's problems have been fixed. My basic requirement is to be able to trim video segments out of larger .mpeg files captured from other sources. The files play just fine on VLC. However, in almost every case, even the smallest edits in Avidemux introduce audio sync problems. It has many other features I would like to use. Unfortunately, if you can't edit a file without losing sync, the entire application is useless.

So, on the web site there's this "warning." Does this mean I should wait for version 2.5.5. to be fixed?

"Warning:The win32/64 2.5.5 versions are named 2.5.4 (r7200) and lack one commit regarding mpeg layer2 audio."

I had major issues with audio and subtitle sync. It was delayed by anywhere from 2 to 4 seconds. Had to revert back to version 2.5.3 which worked flawlessly. This had a different problem. A number of H/X264 rips with compressed headers would appear as simply green screen. I then switched to Handbrake which had its own problems with sharpness. Finally I worked out a flowchart for getting the exactly what I wanted as a final result.

What I need in my final result was 2000 kbps XVid Mpeg4 ASP, 720p resolution, sufficiently loud AC3 5.1 audio and SRT subtitles. This would make the final file of decent size 2000 to 2200 mb, compatible with all standalone players and playable on Atom powered netbooks also.

First of all I reverted to version 2.5.3. If the audio was DTS I would convert to AC3 using freeware SPG Audio Converter selecting AC3 and "Very High" as the format and quality setting. Inspect the file with MediaInfo to check if it had header stripping audio or video heders. If is was such then remux using mkvmerge 4.4 with the header compression set to off. Extract the subtitles. Rip the newly created mkv file through Avidemux 2.5.3 with my required settings + msharpen filter at default settings and external AC3 (512 kbps created by SPG audio converter) file as the audio source. Depending on the volume level of the AC3 file I would select DRC and gain between 3 and 5. Select mkv as the container and save. I always say NO to the H/X264 message that pops up when avidemux scans the input file.

I then run the resulting file through mkvmerge, add the previously extracted srt subtitles file and necessary comments to the track and global options. Then I am done.

Till today I was not aware that the compressed header was the problem for the green screen. Now that I know it has solved all my problems. It is slow but then I run 2 instances of avidemux simultaneously - my PC can handle it. CPU utilization does not exceed 70%.

I am from photographic field where every hair and pore on the face counts. The final result is a whole lot more than good enough. Handbrake does not come even close in quality!

Finally I have just downloaded the version 2.5.5 and will try it out tonight. I hope the sync problem from 2.5.4 has been taken care of.

I use this program for three purposes: to quickly change from one container to another (say avi to mp4) without recoding, adding multiple videos into one long file, or to use its crop feature to measure how much I need to trim off the edges of a video to eliminate the black bars.

I'd use it for much more, but every file I encode, regardless of the starting format, seems to have issues. Some videos (even just copied) have sync issues, while others have stutter issues with a pause every few seconds in the video. Its sad, because I really do find it easy to use.

One of the few editors that can work with .MOV files.

Good and fast - for my .MOV files it always warns about using B-frames - so there is some problem playing the actual video (stuttering)- but I can go to time and (it automatically jumps to the nearest key or intra-frame) to trim edit .MOV files - the resultant edited videos are fine.

Saving is still a bit of a mystery for me - I just save to .MP4 - which is the same internal format as my original .MOV - as I understand just a different container - then the saving is very fast in seconds - which shows AviDemux doesn't have to re-encode the video to save. I can't see how to save back to .MOV - but I can always convert back from MP4 to MOV - if necessary - using something like Quick Media Converter.

Ive weaned myself off Virtualdub and TMPEGEnc with this great free bit of software, but it helps to know your way around digital video generally ! It does pretty much anything I want it to, mostly hard coding subtitles, raising sound levels, and converting avi to DVD. It supports vbr mp3 audio without any sync issues I tended to get with VDub. It will do framerate conversions without a problem.
My top tips:
1 - To get all the required info about a movie file, open it in Avidemux and click the Gear symbol that sits on the toolbar between Save and Calculator
2 - To do a quick and dirty conversion to dvd, open the avi/mkv file, then click Auto -> DVD. Then click Calculator, select MPEG, select your target disc size (ie DVD5), click apply and close. Then click save, give it a name foo.mpg always works for me !!

Great tool for encoding your DV.avi-Files to MPEG-2.mpg-Files without any AV-sync issues. These created MPG-Files can be used to create a DVD with GUI for dvdauthor.

There is the possibility to delete/edit the MP4-tag of MP4-Files created with Avidemux: Open your MP4-File in Mp3tag and delete/edit the information in the File. Test it and be happy with this software.

I never thought of such a Converter or Encoder to be Roaming around there in internet !
It was awesome and great !
But the only problem is it keeps on giving its name as titles in title bars of common players like VLC media player ! Is it is possible to get rid of it ???

I love Avidemux but it's mp4 (h264) editing capability is limited. It can cut only at I frames (start & end) and I too had audio sync issues. For mp4 i would rather use cut assistant as gui for mp4box.

I have no problem editing MP4 files containing AVC/H264 video without having sync problems. To encode, I use Handbrake or Staxrip. For editing, I use AviDemux, which works fine.

This app has a lot of promise, but A/V sync issues and too many hoops to jump through to avoid it will hold it back until resolved. I can't get almost anything to encode without horrifying A/V sync issues.

I've commented on v. 2.4. This comment is specific to all the 2.5 builds I've tried. If you wish to use this tool to quickly convert video to .avi output using xvid codec one-pass bitrate, stick with v. 2.4. With all the 2.5 builds I've tried the output looks as if a semi-transparent checkerboard was placed over the frame. The output is not watchable. I've pointed this out on AviDemux forum and the response amounts to "use 2 pass" whereas in v. 2.4 single pass bitrate 1500 with highest motion detection(6) produces very good output from many sources. It seems there's no interest in even finding out this is a problem, never mind a fix.

If you use xvid one-pass mode, either use v. 2.4 or wait for 2.6.

Replaced Virtualdub for me!

Lots of options and great AUTO modes, the only drawback I could find is that the Stored/Compressed Aspect Ratio cannot be set to be different from the Playback Aspect Ratio.

Still, for a freeware program, it is great. GREAT.
