The issue with this method (with any software) is the fact that the three clips you join (concatenate) must have the same encoding parameters. There are many parameters other than basic resolution, framerate etc that will differ between the encoded clip and the non encoded clips. This will cause issues when concatenating. Even if the clips do concatenate, you will likely discover playback issues on some devices/players.

After loading a *.mp4 video into (portable) Avidemux v2.8.2 on Windows10 I setup all parameters "as usual" and clicked then menu file--->queue to add the job to joblist. I guess "Queue" means "Add to joblist" because there is no menu "File--->Add to joblist"

According to https://www.avidemux.org/admWiki/doku.php?id=using:joblist
I can view the current joblist by clicking on menu

File--->joblist

But there is no such menu (have a look at the attached snapshot).

However I started the other program avidemux_jobs.exe from Avidemux installation directory and though the job would be listed there.

But there is no job here. the list is empty.

Why is no job created and added to joblist?
How can I view joblist otherwise?

If I don't assign the current encoding to joblist but just click File--->Save the video is encoded successfully.

But I want to setup multiple video encodings and then perform one run for all.
How can I achieve this otherwise?

One more idea: The job files *.py are  created but not in the default directory C:\Users\<username>\AppData\Roaming\avidemux\
but in the new directory

D:\tools\Avidemux\settings\jobs\

since I setup a portable Avidemux installation. So I guess Avidemux_portable.exe and avidemux_jobs.exe do not know where to search for the *.py job files.
Any chance to tell them the folder?

Something like a command line parameter

avidemus_jobs.exe -dir="D:\tools\Avidemux\settings\jobs\"

?

Or entering the jobs folder path somewhere else in settings?

If not: This option should be added to next release

I'd like to cut commercials out of recordings (mkv with H264 MPEG-4 AVC + MPEG AAC Audio mp4a) as quickly as possible. avidemux can only cut at key frames in copy mode. I could split the recording into part A, B (with commercial) and C at the nearest keyframes, then cut the commercial out of B, re-encode B and merge parts A, B and C. Is there a script or plug-in for avidemux that can do this? If not, is there an alternative to avidemux that can do these steps automatically?

First thanks for Avidemux.  Avidemux is an excellent video editor for handling lengthy screen recordings, such as gameplay, for example. Often, we record the screen for extended periods. Afterward, we might want to locate a brief segment containing relevant content within a very long recording. It's not uncommon for significant moments to coincide with loud noises and loud chatter. For this reason, I would appreciate a simplified, dim-colored bar graph of accumulated decibels alongside the timeline. This feature would be a useful addition to Avidemux, making it easier to identify key moments in long recordings based on audio levels. I would suggest to start to try the implementation this way:  First, calculate the sum of the decibel values of the samples from the current audio track within each group of frames or something. Then, normalize this data relative to the highest value found. Finally, display these normalized-sized bars alongside the timeline in dim colors.
If I knew how to program computers, I would try to do this. Unfortunately, I do not. I started a new topic because the old one was a necro and there was an alert suggesting to do so. Thank you very much for your attention.

Attach photo after and before. After re-econde quality is worse. Respond to Geo_Log.

AC3 (lav) is the only AC3 option in the drop down list. The second AC3 option was removed quite some time back, no? Only AC3 (lav) in the plugins folder.

Yes, I reproduced the issue using no audio filters.

Quote from: eumagga0x2a on May 12, 2024, 06:59:10 PMYes, I should have requested refresh of nightlies nevertheless.

Yes please

I think it would be a handy feature: dialog with confirmation about closing the Avidemux instance, which you can enable or disable in Preferences\ User Interface tab. It's very easy to close accidentally two or more opened program windows.

Quote from: Drakon66 on April 29, 2024, 03:57:42 PMOk but in avimedux is possible to append ?

Only as an internal audio track of a video. The video is appended, thus the audio track in that video becomes a continuation of the existing one (if the properties of the audio track like codec and codec settings, sampling frequency and number of channels match).

Quote from: Drakon66 on April 29, 2024, 03:57:42 PMAnd append you mean merge or just add second one ?

"Append" always means to continue after the end of the existing something. "Merge" is a more general term, "make one out of several", describes the final result of the processing.

Quote from: Drakon66 on April 29, 2024, 03:57:42 PMWhen I add new track audio a have two diffrent track or I can replace it.

You have both options. Adding an external audio track (telling Avidemux to use an external audio file as an audio track) at position two, as far as the audio file is accepted by Avidemux, either adds a second audio track additionally to the first internal one or replaces the second internal one. To replace the first audio track, you need to select an external audio file at position one.

In any case, you cannot mix (like an overdub) an external audio into an existing audio track with Avidemux. This is a job for a proper audio editor.

Thank you, got the samples. Please specify which AC3 encoder you used. On Windows, there might be not just the AC3 encoder in libavcodec but also Aften among audio encoder plugins in Avidemux.

Quote from: jimmy on May 15, 2024, 08:33:26 PM- the only change I wanted to make to the AC3 6 channel was the gain

Was it necessary to reproduce the issue? Does re-encoding without any audio filters result in the same messed up channel layout?
