Avidemux Forum

I am using the Windows version 2.8.1.  When saving a *.mp4 or *.mkv file, the program adds "_edit" to the filename when saving into the source folder.  It does not add "_edit" when saving a *.MP4 or *.MKV file.  It does detect that a file already exists and prompts to either overwrite or change the filename.  In Windows, filenames are not case sensitive, so saving a file named aaa.mp4 will overwrite an existing aaa.MP4 file.  Suggest that in Windows "_edit" should be appended to the saved filename regardless of the case of the file extension.

Thank you, so it was apparently related to VP9 decoding in hardware via DXVA2. If crashes resume, please try disabling hw accelerated decoding first.

Having different versions of Avidemux present on the system should not matter as long as none share an install directory and none run simultaneously. However, unless they are run in portable mode (requires write permissions to program folder), they all would share the same profile (%appdata%\avidemux) which may result in problems due to incompatible changes to configuration.

Except for the installer, Avidemux doesn't enact Windows registry at all. It uses %appdata%\avidemux for user data like Avidemux settings and custom scripts and %localappdata%\avidemux for logging.

The crashes appear random for all files, if one file crashes on closing (Ctrl+W) I can reload the same file & close it without a crash, I haven't been able to find a pattern other than the crashes are pretty spread apart, there's usually a long break and sometimes it wont crash all day (very odd).

Completely forgot the last stable version of Avidemux 2.8.1 was installed (havent used in awhile) and have been using Nightly builds from another directory, not sure if there was any conflicts there but after posting here I did a Revo uninstall on avidemux and let it delete all traces / folders, I then deleted my nightly folder and unzipped a fresh copy of same nightly build ive been using, so far I haven't had any crashes so fingers crossed.

I'll be sure to try your other suggestions if it crashes again I'm curious what the admlog file might show.

also not sure if this helps but when it started crashing I had made a crude screenshot from a previous nightly build and it shows the full text from error popup window.

Rein interessehalber, welche Software führt hier Transkription mit anschließender Sprachsynthese aus (kenne nur als gruseliges "misfeature" von YouTube), und lässt das Ergebnis auch noch exportieren?

Erstellen kann man in Avidemux keine Tonspur, aber eine bereits erstellte und im kompatibel Format als rohes, nicht in einen Container gepacktes WAVE (signed integer 16 oder 24 bit), MP2, MP3, AC-3, EAC-3, DTS-Datenstrom bzw. AAC in ADTS-Envelope vorliegende Tonspur kann man als eine externe Tonspur einbinden und je nach gewähltem Muxer (Ausgabeformat) in die generierte Videodatei schreiben. Externes Audio in einem Container wie MP4 (oft mit Endung .m4a) oder Matroska (oft mit Endung .mka) wird nicht unterstützt.

Quote from: AA on November 17, 2025, 09:11:44 PMFalls ja wie geht das?

Im Menü "Audio" unter irgendwas mit "Tracks" (zumindest in der englischen Oberfläche), im Dropdown-Menü für die jeweilige Tonspur unter "Track hinzufügen" (sinngemäß).

Does "randomly crash on closing a video" mean that loading and closing one and the same video file sometimes crash, sometimes doesn't?

The first thing to check would be the log file (admlog.txt) from %localappdata%\avidemux. It might give some clues where the crash happened.

Does the last available official native nightly build from May 26 misbehave in the same manner? (Unfortunately, there was at least one important crash fix which didn't make it into that build, but if I am not mistaken, it would trigger a crash on loading a video).

Does disabling hw accelerated decoding (NVDEC, DXVA2, both of them) work around the crash?

Hi lately when using avidemux the program will randomly crash but only when I'm closing a video file, The window popup says "ExceptionFilter" and a bunch of text below that starting with Exception_Access_Violation.

I'm running a nightly build file ending in r241212_win64Qt5_9 in Win 11, this build has been fine for months but then all of a sudden started crashing this way at random.

Is there a proper way to do a clean install for example should I be deleting any Avidemux directories found in AppData/Roaming before trying another nightly build.

Guten Abend,

habe gerade von Avidemux gehört und installiert. Bin neu hier.
Habe ein paar Videos geschnitten, um sie von Englisch ins Deutsche per Tonspur zu übersetzen lassen mit anderen Programmen natürlich.

Kann man das auch mit Avidemux machen, also eine andere (deutsche) tonspur erstellen?
Falls ja wie geht das?
Danke im Voraus!

Viele Grüße

MaxSecure like Cynet is one of many antivirus vendors integrated by VirusTotal service. All antivirus engines are prone to false positives. Meanwhile, the false positive for ADM_core6.dll by Cynet seems to have been corrected: https://www.virustotal.com/gui/file/d6c4d78667f0185ddd2d315ce3c76967339c76bfb9e8476e29ba2862292a705c?nocache=1

The false positive by MaxSecure for fontconfig.dll seems to persist: https://www.virustotal.com/gui/file/c085b9a1a80e0ab66582a8952390ab3ccff0b8f5cfa196cf01da0ed16129c21e?nocache=1

Everything following "because" is false and completely misinterprets the content of the screenshot.

Yes, the latest available 2.8.2 nightly build is far less buggy than the last release. If cross-compiling from source is out of question, resorting to official nightlies is the second best option (no published checksums or digital signatures, unfortunately).

If you need the VC++ version.

The Win64 installer currently hosted on FossHub is blocked by my IT department because it is bundled with "MaxSecure" malware:

Win64/VC++ 2.8.1 Install (64 bits), FossHub,

Is there any other place where I can download Avidemux without the bundled "MaxSecure" malware?
