Avidemux Forum

Hi
I hope someone can help me....
I need a script to copy a Folder of MKV Videos to MP4 Videos, with the same Video and Audio Copy, So its basically just changing all the Videos inside the folder from MKV to MP4, with unchanged Video Format and Audio Format quality.
Does anyone have a script for me to use please, or teach me how to do this?

Many Thanks

If you are not afraid of doing own research and thinking logically filling in missing bits of the solution, http://avidemux.org/smif/index.php?topic=17187.0 could give you pretty much everything needed to find your own.

Please be aware that the parameters of the Mp4 muxer have been extended since 2.7.0 release to allow to force display aspect ratio, mp4 container is generally much more restrictive than MKV WRT codecs so that conversion may easily fail.

In any case you are much better off using the latest Avidemux nightly instead of the outdated 2.7.0 release. Alternatively, use just ffmpeg directly (Avidemux adds no benefits in your use case).

Thanks
Will give it a try  ;)

Thanks got it all working BUT I get an error message, Which is below...
I have to select ok for every file loaded for it to do the conversion, The conversion works great, apart from having to select ok for every file loaded.

TinyPy: Exception
Exception : (tp_load) cant get filesize
BackTrack: File:py2bc.py,line50

Here are my Bat file Settings

set avidemux="C:\Program Files\Avidemux 2.7 - 64 bits\avidemux.exe"
for %%f in (*.mkv) do %avidemux% --load "%%f" --run pui.py --save "%%~nf.mp4" --quit

Here are my Py file Settings

adm = Avidemux()
adm.setContainer("MP4", "muxerType=0", "useAlternateMp3Tag=True", "forceAspectRatio=False", "aspectRatio=1")

Any idea what is wrong

Thanks

Basically it means that ADM_fopen fails, I'll try to look into it later today.

Thanks buddy

Would this be because of the current software version?

I don't think so. Why do you use the GUI version instead of the CLI one?

(The release is really not an option because you lose the last few frames of the video if it contains B-frames)

Could you please create a directory with just a single MKV video in it, run your batch and post admlog.txt resulting from this run if you get the same error?

Where do I post admlog.txt?

If possible, compress it and attach it to your reply. If it doesn't work due to antispam measures, please send it by a personal message.

The script is now running since I chance to CLI, BUT now with the input video MKV file size 1.30GB, when it converts to MP4 the finished file size is 32.6KB

I don't know how or where to get the admlog.txt

Thanks for helping me

You find it in %localappdata%\avidemux\

I'm sorry, could you please attach a ZIP compressed version? I don't have unrar on my smartphone.

ok one min

There you go

Thanks, the log shows that Avidemux crashed because no video had been loaded. The command line doesn't mention a --load option, subsequent call of --run for your project script  leads as expected to a crash.

ok what am I doing wrong?
There are 3 MKV Videos inside the folder

Here are my Bat file Settings

set avidemux="C:\Program Files\Avidemux 2.7 - 64 bits\avidemux.exe"
for %%f in (*.mkv) do %avidemux% --load "%%f" --run pui.py --save "%%~nf.mp4" --quit

Here are my Py file Settings

adm = Avidemux()
adm.setContainer("MP4", "muxerType=0", "useAlternateMp3Tag=True", "forceAspectRatio=False", "aspectRatio=1")

Thanks

I'm not really familiar with Windows cmd.exe scripting. Does loading a file alone work? Leave out --run and --save commands for testing purposes and attach a new admlog.txt, please.

Not sure how to do that, I see no out --run and --save commands in the script

Leave the emboldened part of the command line out.

Thanks, it is not from the run with the --load option alone, but it includes useful information. Will look into it.

Thank you

Could you please try out adding --nogui option before --run but after --load?

(This does not do what one might think. Instead, it prevents dialogs from popping up. The option would not fix the exception but might hide the unpleasant effects)

It has the same effect of error

TinyPy: Exception
Exception : (tp_load) cant get filesize
BackTrack: File:py2bc.py,line50

Thanks, it doesn't suppress dialogs opened for errors then. Will try to find out what is going on later tonight.

Once it has done a scan this pops up

TinyPy: Exception
Exception : (tp_load) cant get filesize
BackTrack: File:py2bc.py,line50

I have to select OK and then the file will continue fully and finish, with no other errors

SOLVED

I messed around and done this, and it works great, NO errors and copies Video and Audio from Mkv to MP4

set avidemux="C:\Program Files\Avidemux 2.7 - 64 bits\avidemux.exe"
set videocodec=Copy set audiocodec=Copy
for %%f in (*.mkv) do %avidemux% --video-codec %videocodec% --audio-codec %audiocodec% --force-alt-h264 --load "%%f" --save "%%~nf.mp4" --quit

Once again Thanks for getting me advice Cheers

for %%f in (*.mkv) do %avidemux% --video-codec %videocodec% --audio-codec %audiocodec% --force-alt-h264 --load "%%f" --save "%%~nf.mp4" --quit

Just a small nit: --load should always come first, because depending on Avidemux settings, this will reset video codec to a user defined default value. Additionally, the option --force-alt-h264 has been removed from Avidemux since ages.

The reason for the error was most likely missing full path to the .py file so that it was simply never loaded (it works with relative path on Linux, but maybe this doesn't apply either to Windows or to your setup, so that the .py file wasn't located in the folder where the command was run).

Finally, in your command line above you don't set output format, the resulting .mp4 should be really a MKV with .mp4 file name extension.

Just for reference: A more or less correct batch would have been

set avidemux="C:\Program Files\Avidemux 2.7 - 64 bits\avidemux.exe"
set videocodec=Copy
set audiocodec=Copy
set outfmt=MP4
for %%f in (*.mkv) do %avidemux% --load "%%f" -video-codec %videocodec% --audio-codec %audiocodec% --output-format %outfmt% --save "%%~nf.mp4" --quit

I have added gatekeeper code to deal with situations when script file provided via command line can't be found at the given location. In the future, users won't face a tinyPy exception message if they pass a wrong path to the --run option.

Great Thanks

I was just wondering if there is a Batch to detect AC3 within Video, as I would like to convert AC3 over to HE-AAC.
I have MediaInfo, but having to manually check every video is a pain.
Also is it ok to change the container AVI to MP4

Thanks

ffprobe is part of the FFMPEG package.  The following batchfile should work from cmd line or drag-and-drop (not tested) for win7 or later.

Find_AC3.bat
@echo off
cls
for %%F in (%*) do (
ffprobe -v error -show_entries stream=codec_name -of default=noprint_wrappers=1 "%%~dpnxF" | find "ac3" >nul && echo "%%~dpnxF" contains AC3
shift
)
pause


Result using a cmd line of:
Find_AC3.bat "D:\20161130 - OIC Christmas Carols\Video\00000.MTS" "D:\20161130 - OIC Christmas Carols\Video\00001.MTS" *.mp4


"D:\20161130 - OIC Christmas Carols\Video\00000.MTS" contains AC3

"D:\20161130 - OIC Christmas Carols\Video\00001.MTS" contains AC3

"D:\00000.mp4" contains AC3


















Press any key to continue . . .

The .MTS files are AVCHD media files from my camcorder. Most of the MP4s in D:\ do not contain AC-3 so they produce blank lines.

The portion after "&&" will only execute if the find was successful. With a little more mucking around it would be possible to only run FFMPEG to perform the HE-AAC audio stream conversion if the find was successful.

The ">nul" hides double FIND screen displays of "ac3" to reduce clutter.

"%%~dpnxF" is used instead of %%F as it is not affected by the presence or absence of "" around *.mp4

Dan.

Just a few words to conversion AVI --> MP4: If the video is H.264 or HEVC and contains B-frames, direct conversion will result in a file not smoothly playable in some players like VLC. The reason for that is AVI not storing presentation timestamps while the presence of B-frames means that frames are stored not in the order they are displayed. Avidemux offers a feature to reconstruct missing information by decoding the entire video, but I am not sure it is scriptable.

ok thanks

Perhaps your version of FFPROBE is returning a different string e.g. AC3 or AC-3 instead of ac3. To troubleshoot, try a simpler command on the cmd line, not a batchfile, with a media file that you already know contains an AC-3 audio stream  e.g. try just:

ffprobe -v error -show_entries stream=codec_name -of default=noprint_wrappers=1 "d:\20161130 - OIC Christmas Carols\Video\00000.MTS"

OK, now try this (command on one line):

If that works increase it to (command on one line):

ffprobe -v error -show_entries stream=codec_name -of default=noprint_wrappers=1 "C:\Users\jonwr\Desktop\Dark Net - 2x01 - My Mind.mp4" | find "ac3"  >nul && echo  "C:\Users\jonwr\Desktop\Dark Net - 2x01 - My Mind.mp4" contains AC3

Dan.

ffprobe -v error -show_entries stream=codec_name -of default=noprint_wrappers=1 "C:\Users\jonwr\Desktop\Dark Net - 2x01 - My Mind.mp4" | find "ac3"

I get...codec_name=ac3

I get..."C:\Users\jonwr\Desktop\Dark Net - 2x01 - My Mind.mp4" contains AC3

So the basic command is working fine. The problem must be in the FOR IN () DO loop.

Try this batch file:

Find_AC3.bat
@echo on
cls
for %%F in (%*) do (
ffprobe -v error -show_entries stream=codec_name -of default=noprint_wrappers=1 "%%~dpnxF"  | find "ac3">nul && echo "%%~dpnxF" contains AC3
shift
)
pause

use it from the cmd line with a file containing AC-3. Since ECHO is ON you will see the lines in the batch file, and then you will see them again, this time with the FOR IN () DO loop interpreted and "%%~dpnxF" expanded:

D:\>Find_AC3.bat "D:\MKV test\test 100.mkv"

I see:

That's unusual. In a batch file, (but not at the cmd line), you need to use the double percentage symbols: %%F

But when the batchfile is run, the first percentage symbol is stripped off, leaving just %F

Notice how mine is doing this and yours is not.

Just my luck, this has to happen to me lol

The same applies to %*

Mine is immediately changed to the command line parameters following the batchfile name, here just a single media file. Again this behaviour is expected inside a batch file as compared to issuing the command at the cmd prompt.

Dan.

This is what am getting in a Batch now...

Try this. Create this batch file in a text editor:

Batch_Paramenter_Parsing.bat
@echo off
echo %%1 is %1
echo %%2 is %2
echo %%3 is %3

echo %%* is %*

Run it from the cmd prompt with some parameters:

No, use:
batch_parameter_parsing.bat 10 20 30 40 50 60 70 80 90

Nothing happens it just returns

C:\Users\jonwr>batch_parameter_parsing.bat 10 20 30 40 50 60 70 80 90

C:\Users\jonwr>

I think you're getting confused with the cmd prompt. The LHS, before the ">", shows which drive and which directory you are currently situated in. For example:

C:\Users\jonwr> means that you are on C: drive, in the jonwr subdirectory which is under the Users directory

So, to change directory:

C:\Users\jonwr> cd ..  (meaning "jump up one level")  or  cd C:\users  or  cd \users  would change the prompt and your location to:
C:\Users>

And, from there  cd C:\users\jonwr  or cd \users\jonwr or cd jonwr  would change you back to:
C:\Users\jonwr>

And if you had a D: drive,   
C:\Users\jonwr> D:   would change you to
D:\>  (the root directory of D: drive)

Edit this batchfile in an text editor, change @ECHO OFF to @ECHO ON, save your change and then rerun the command line under discussion.

I really don't understand this.


I've changed @ECHO OFF to @ECHO ON in my Batch

I forgot to mention: from any location typing DIR or dir will show you the files in this directory and any sub-directories (aka "folders") off of it.

Assuming you have created the batch_parameter_parsing.bat text file in your current directory, typing
TYPE batch_parameter_parsing.bat or type batch_parameter_parsing.bat
will show its contents on your screen. Please do this and report what you see.

Two things:

"0" is the size of the file in bytes. So batch_ parameter_parsing.bat has no contents. This can't be the file you are editing. If it is, you have just wiped its contents, probably by saving it incorrectly. That's why TYPE batch_parameter_parsing.bat is not displaying any lines of code.  What text editor are you using?

You should not have a empty file titled "cd" as this is an important Windows internal command. This may prevent you changing directories. To remove it, type at the cmd prompt:

DEL CD

and then type DIR at the cmd prompt again to check.

Any when you reopen batch_parameters_parsing.bat in Notepad are you seeing any lines of code this time?

This is what is shown in editor
Before and After DIR is the same

@echo on

   ffprobe -v error -show_entries stream=codec_name -of default=noprint_wrappers=1 "%%~dpnxF"  | find "ac3">nul && echo "%%~dpnxF" contains AC3

OK. Now exit Notepad. If DIR still shows 0 as the filesize of Batch_parameters_parsing.bat, this would indicate the file that you had open in Notepad is not the same file as in this directory. (You can't have two files with the same filename in the same directory, but you can if they are in different drives or directories.)

OK, I'm fairly certain you've got 2 batch_parameter_parsing.bat files in your system. What you are opening in Notepad is probably in your documents folder.  Do a Windows search for batch_parameter_parsing.bat and look at their location and size.

Windows hides the extension of files it knows how to handle to avoid confusing novices. Unfortunately this can confuse them when they want to create batch files (a text file containing a series of lines of code) because what looks like a batch file called batch_parameter_parsing.bat might actually be batch_paramenter_parsing.bat.txt

The later, although having the same contents, is not an executable file.

Sorry that should have been

Batch_parameter_parsing.bat not Batch_parameters_parsing.bat


Anyway, according to DIR, the one in C:\Users\jonwr has no contents.

Right I did another scan and found 2

This one was empty so I put it in the bin
C:\Users\jonwr


this one is 88 Bytes
C:\Users\jonwr\Desktop\AC3_TEST\Batch_parameter_parsing.bat

I went back to CMD and did
Batch_parameter_parsing.bat

OK. Batch_parameter_parsing.bat is not in your current location (the C:\WINDOWS\system32 dictionary). So if you want to execute it you have 3 options:

• Specify the full path in front of the command:
  C:\Users\jonwr\Desktop\AC3_TEST\Batch_parameter_parsing.bat 10 20 30 40 50 60 70 80 90


• First change to the directory it's located in and then execute it (two separate commands):
  CD \Users\jonwr\Desktop\AC3_TEST (no need to specify C: if you are already situated on that drive)
  Batch_parameter_parsing.bat 10 20 30 40 50 60 70 80 90


• Either copy Batch_parameter_parsing.bat to a directory that is already in the PATH list of directories, or add its location (C:\Users\jonwr\Desktop\AC3_TEST) to the list of directories in your PATH list. When you try to run a executable (a file with .COM, .EXE or .BAT file extension), and you don't specify its location, the operating system looks first in your current location and then in the locations in the PATH list. If it's in one of these locations you can use just:
  Batch_parameter_parsing.bat 10 20 30 40 50 60 70 80 90   
  while situated in any location.

For example, you might have lot of little utility programs and batch files which you want to be able to run from anywhere. Type PATH at the CMD line. Mine shows:

[/list]PATH=C:\Mingw\local64\bin-video;C:\Mingw\local64\bin-audio;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86);C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\GNU\GnuPG\pub;C:\Program Files (x86)\GNU\GnuPG;C:\Program Files (x86)\WinMerge;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\QuickTime\QTSystem\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\Common Files\Acronis\VirtualFile\;C:\Program Files (x86)\Common Files\Acronis\VirtualFile64\;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files\nodejs\;C:\Program Files\gnuplot\bin;C:\Users\Dan\AppData\Local\Microsoft\WindowsApps;d:\YouTube_dl;C:\Users\Dan\AppData\Roaming\npm;

Now we make a C:\Utilities directory. From anywhere on C: type
MD \Utilities

Change to this directory
CD \Utilities

The prompt will now show C:\Utilities> to indicate where you are.

Copy batch_parameter.bat to here:
Copy \Users\jonwr\Desktop\AC3_TEST\batch_parameter.bat

Because you did not specify a destination (i.e. Copy \Users\jonwr\Desktop\AC3_TEST\batch_parameter.bat \Utilities), it will use your current location as the destination of the file copy.  Confirm the copy was successful by typing:
DIR

Now we need to add C:\Utilities to your path list. In Windows, go to  Control Panel | System | Advanced System Settings | Environment Variables.  In the "User Variables for jonwr" section, highlight the "Path" line and then click on "Edit". Click on "New", type in c:\utilities (case is not important in Windows) and click on OK, and then OK again, and OK again to finish closing all these windows.

We nee to load a new instance of CMD, as the current instance will not be aware of the change in the path yet.  If the CMD window is still open, close it by typing EXIT, then type CMD again to open as a new instance. Type PATH to check again. I see (scroll to the end of the line):

PATH=C:\Mingw\local64\bin-video;C:\Mingw\local64\bin-audio;C:\ProgramData\Oracle\Java\javapath;C:\Program Files (x86);C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\GNU\GnuPG\pub;C:\Program Files (x86)\GNU\GnuPG;C:\Program Files (x86)\WinMerge;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;C:\Program Files (x86)\QuickTime\QTSystem\;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\Windows Live\Shared;C:\Program Files (x86)\Common Files\Acronis\VirtualFile\;C:\Program Files (x86)\Common Files\Acronis\VirtualFile64\;C:\Program Files (x86)\Common Files\Acronis\SnapAPI\;C:\Program Files\nodejs\;C:\Program Files\gnuplot\bin;C:\Users\Dan\AppData\Local\Microsoft\WindowsApps;d:\YouTube_dl;C:\Users\Dan\AppData\Roaming\npm;c:\utilities;


Now you can type Batch_parameter_parsing.bat (or just batch_parameter_parsing) 10 20 30 40 50 60 70 80 90 from anywhere and it should execute.

Note: when working at the cmd prompt, you have a few aids. The F3 key will help you auto-complete paths and filesnames. For example, type:

CD \u  [Press F3 once or twice]. It should complete to
CD \Users
Continue typing
CD \Users\j  Press F3 and you'll get:
CD \Users\jonwr

Same with copying a file e.g if operating from c:\users\jonwr
c:\users\jonwr> copy des [F3]
copy Desktop\AC [F3]
copy Desktop\AC3_TEST\ba [F3]
copy Desktop\AC3_TEST\batch_parameter_parsing.bat  \u [F3]
copy Desktop\AC3_TEST\batch_parameter_parsing.bat  \utilities

You can also use Up-Arrow to bring back previous commands, edit part of it and then press F3 again to try for a match.

You can mark a string of characters at the prompt by clicking-and-dragging the L. mouse button.  Press Enter to copy the highlighted portion to the Windows clipboard.

You can paste from the clipboard which can have been filled from within the cmd prompt window, or from a copying operation in another program like Notepad (most windows programs use Ctrl-C for Copy), using the Ctrl-V (Paste) hot-key.

Thanks @dosdan !

Any idea how to make it work with directories that contain other files than video ? It fails when I have folders with text files in it :/

If running the batchfile from the cmd line in the current directory, specify the filetypes you want by nominating one or more wildcards+file extensions e.g.

Find_AC3.bat *.mp4 *.mts


If operating by drag-and-drop from the Windows desktop, open the directory first and sort the icons (or details) by filetype. (For this type of work you really should select the Windows option that will not hide known file extensions in a directory listing - hiding them is only useful for novices.) Select a block of media files, say all the MP4s, using the standard Windows L.click (start of block) & Shift-L.Click (end of block) and then drag the selected group onto the Find_AC3.bat icon.
