Avidemux Forum

Good morning friends, I am running Windows 10 Pro and I have downloaded Avidemux software on my PC. But I am having a problem when I am trying to install this on my PC. I am getting this error message when I am trying to install this "Unable to make changes to your software, The software change returned error code 0x643."

Does anyone have any idea about the issue? I have tried to download this from the official site of this software. Then I dont understand what could be the issue. I am seeking help friends, if anyone assists me to resolve the issue, it would be helpful. Thank you.

I'm using 2.7.2
as is likely evident by my question to say my knowledge is limited would be an understatement.
I'm making clips using copy mode and .mp4 muxer from a video encoded using CBR and the copied videos are coming out with varying bitrates. while I'm inclined to assume that that's because the bitrates in the original do vary despite the 'constant' designation; when saving the file I'm also getting "encoding file..." rather that "saving..." or "copying..." I'm wondering there is reencoding going on.

Bonjour,

La version 2.8.1 est très ancienne, veuillez la remplacer par une version récente du développeur (nightly) 2.8.2. Si le problème persiste, veuillez fournir l'analyse de MediaInfo pour un fichier que votre décodeur TNT est capable de lire et pour un fichier produit par cette nightly qu'il ne peut pas.

Selon le rapport de MediaInfo, il peut être nécessaire d'inspecter des échantillons.

Bonjour, je voudrais vous signaler un problème de lecture des films compressés en x264 avec Avidemux par mon décodeur TNT ( je n'ai bien sûr aucun problème avec un logiciel comme VLC )

Pour résumer, les fichiers encodés avec la version 2.7.5 sont lus par cet appareil, mais à partir de la version 2.7.6, jusqu'à la dernière 2.8.1, seul le son fonctionne, la vidéo n'est pas lisible.

Les paramètres de compression sont exactement les mêmes, et je pourrais fournir des fichiers échantillons ainsi que les fichiers STATS issus de la 1ère phase de compression par exemple.

Je vous remercie de m'apporter des conseils si vous voyez d'où peut venir le problème.

MPC-HC includes Media Info. Should at least tell you what subtitles you have.

File/Properties Media Info tab.

Do you want to hardcode ("burn" into the picture) subtitles into video, which implies that the video has to be re-encoded, worsening the quality? Or do you want to get a video in a different container (MP4 instead of Matroska), keeping subtitles as a track, which allows to use copy mode for video and to disable subtitles during playback?

If it is the latter, you cannot use Avidemux for this task at all (use ffmpeg on the command line instead).

If it is the former, it depends on the type of subtitles in the subtitle track. For SSA tracks you could use e.g. if the subtitles are stored in MKV as track no. 5

mkvextract /Path/to/Source.mkv tracks 5:/OutputPath/to/mySubtitles.ssa
and subsequently use the SSA/ASS/SRT video filter in Avidemux to hardcode these subtitles into video.

If you have difficulties to use the command-line utility mkvextract directly, there is a GUI for that (gMKVExtractGUI, never tried that, you are on your own).

The SSA/ASS/SRT video filter in Avidemux expects subtitles as a separate text file in Substation Alpha or in SubRip format (which will be internally converted to Substation Alpha format) for the sole purpose of hardcoding them into the video (which will be re-encoded) using the libass library.

I have an mkv file with subtitles. I want save part of the file to mp4 and keep the subtitles. When I use the subtitle filter it wants me to open a file, which I don't have. Does this mean the subtitles hardcoded in to the original mkv? I'm able to turn them off while playing the file with MPC-HC. I thought that you couldn't turn off hard coded subtitles. I'm confused.

Quote from: eumagga0x2a on March 19, 2023, 06:08:06 PMThat looks like installing Avidemux into a directory with remains of another build or trying to run multiple instances of Avidemux simultaneously.

Yes! I did a "dirty" upgrade over stable, which worked fine with all Win11 security settings but after upgrade, removal, and stable install, cloud protection needs to be disabled, weird. Worked fine before

P.S. Looks like i didn't even have defender enabled as asked for me to sign in first time
