I repeat myself, but the last known good nightly is a cross-compiled r241212 at the moment. It is pointless to take something else.

I don't like to update Avidemux too often because something breaks, or depends on  some certain video driver version, or introduces something I have to take effort to stop like the index files.  I am using ver 2.8.2 and don't want headaches switching.  I'll try another version eventually and probably stay with 2.8.2 because there seems to be very little regard for keeping compatibility.

I've been off on a rant while drinking so take this post however you want to, but no other apps I use, have this much BS maintenance involved, the rest of my apps I just use without ever having to post in a forum about them.


If it needs a newer version of (anything), this is a bad move in my opinion.  Keep it backwards compatible.  Don't be a snob about updating everything.  I won't do that, nor do most users want to unless they drank the kool-aid.

I have never encountered this kind of  skittish force update/change behavior before.  Just stop it, cut it out!  Stop introducing incompatibilities.  Excuses are excuses.  I understand the reasons and suggest that it's foolish.  The worst thing is to limit the audience in order to be lazy.

Do whatever you want, and I will not update regularly because of the arrogance of not respecting keeping legacy systems running.

Don't break things!

I know my post is a big vague, but I contrast this with the many many other apps I use, which don't have this problem.  It seems very much like the developers are snobs that want to artificially ruin compatibility, and I accept that, it is their call to make, and also why they will leave a lot of people not wanting to bother trying every new version of the app.

I actually prefer the current behaviour,
but I can certainly understand that it would irritate other people.

If the behaviour is to change, please make it an optional setting,
that the user can either tick or untick, according to their preference.

Yes and no.  I do minimize it to the tray to get it out of the way so I can continue getting other work done, but even if I don't minimize it, I'm doing batch jobs and when one instance of Avidemux closes, another opens and steals focus again, right in the middle of the screen it puts itself right  on top of the work I'm trying to do in other apps.

So... what I wanted was for Avidemux to not steal focus when it loads, but this is a problem with many apps, but I don't regularly have any other apps with a  GUI opening and closing as a batch job.

I just didn't know enough to realize that there is a solution, just run the batch job calling avidemux_cli.exe instead of avidemux.exe, then it processes it all with the command window staying minimized for the whole job, which is so much better!

I would edit the topic title to read solved since running the CLI does solve it, but apparently this forum has a timeout on editing posts, which is not very user friendly but whatever.

Using internal Python-like scripting in Avidemux, you could do the following:

#PY  <- Needed to identify #
#
ui = Gui()
adm = Avidemux()
ed = Editor()
ext = "mp4"
outputs = ["MKV","MP4","MOV"]
sep = "/"
nbsek = 120
#
# Function to process an individual video
#
def convert(filein,outdir,outidx):
    if not adm.loadVideo(filein):
        ui.displayError("Oops","cannot load "+filein)
        return 0

    offset = nbsek * 1000 * 1000

    if ed.getVideoDuration() < offset:
        ui.displayError("Input too short", "Duration is shorter than " + str(int(nbsek)) + " seconds, skipping \"" + filein + "\"")
        return 0

    adm.markerA = offset

    adm.videoCodec("Copy")
    nbTracks = adm.audioTracksCount()
    if nbTracks > 0:
        adm.audioClearTracks()
        for track in range(nbTracks):
            adm.audioAddTrack(track)
            adm.audioCodec(track, "Copy")
    filename = (splitext(filein))[0]
    if outidx == 0:
        adm.setContainer("MKV", "forceAspectRatio=False", "displayWidth=1280", "displayAspectRatio=2", "addColourInfo=False", "colMatrixCoeff=2", "colRange=0", "colTransfer=2", "colPrimaries=2")
        filename += ".mkv"
    elif outidx == 1:
        adm.setContainer("MP4", "muxerType=0", "optimize=1", "forceAspectRatio=False", "aspectRatio=1", "displayWidth=1280", "rotation=0", "clockfreq=0")
        filename += ".mp4"
    elif outidx == 2:
        adm.setContainer("MOV", "muxerType=0", "optimize=1", "forceAspectRatio=False", "aspectRatio=1", "displayWidth=1280", "rotation=0", "clockfreq=0")
        filename += ".mov"
    else:
        ui.displayError("Error", "Invalid output preset index \"" + str(outidx) + "\"")
        return 0

Save it as a text file with ".py" as extension. You might need to replace the value of sep with "\\" if you use Windows instead of *nix operating systems.

Avidemux will automatically seek to the last keyframe before the specified time offset (default value: 120 seconds = 2 minutes) when exporting the video. If you need more output formats than MKV, MP4 and MOV, you will need to extend the script accordingly. Please keep in mind that most output formats have some limitations regarding compatibility with particular video and audio codecs.

Hello

I would like to cut first 2 minute of multiple video files and keep the rest of those video without reencoding (using copy only)
How can I do that easily?

Thank you

You know, not for nothing, but if the concern with adding a PNG-export feature is wanting to avoid growing avidemux's already-considerable number of menu options, there is a way to avoid that: The "Save as Image" submenu's painfully out-of-date "Save as BMP" option could be replaced with a "Save selection as PNG" feature, and avidemux would have exactly the same number of menu options it had before. 

Some time between almost-a-decade-ago and 2.8.2, this was fixed! swResize now successfully re-loads stored dimensions, when modifying an existing filter. Yay.

For most video formats, you can probably use Handbrake to first extract the single video track (the one you want to edit with avidemux) from the multi-track file. It's an excellent transcoder / remuxer.

I want to share a similar problem, maybe the same of @misterr.

Avidemunx 2.8.2r250526 (Win x64) seems unable to open my Hikvision DVR HEVC recordings.
I attach admlog file and Mediainfo stream properties export file for further analysis.

Just for information, both VLC and integrated Windows media player open the file successfully.

Quote from: tropolite on May 14, 2025, 10:56:52 AMIs Windows version of Avidemux no longer being updated? I haven't seen any update since Dec '24.

Official native Windows nightly builds (built using Microsoft Visual Studio) from https://avidemux.org/nightly/vsWin64/ are back to being functional again starting with 250526. The only known new limitation: uninstall via Windows Settings does not work, at least on Windows 11, which is an upstream Qt installer bug. Use the link to the uninstaller in the start menu or navigate in Windows Explorer to Avidemux install directory and run the uninstaller from there.

The service of providing also official cross-compiled builds https://avidemux.org/nightly/win64 may or may not resume in the future.

Work on integration of important pull requests still stalled, hoping for more time to breathe later in June.

Will probably need to buy recent Intel hardware to be able to assess this problem and other known libva-related problems not existing on older Intel GPUs up to and including the 6th gen.
