How to merge hundreds of AVI and WAV files automatically

[yken]

All AVI and WAV files have same names in one folder. Using Machete, Virtualdub I can merge/mux/multiplex them one by one.
Because each file is 3gb it takes 5-6 minutes for one file. I have more than 100 files. How can i automate this? Which program can do this for me? I only need merge/mux option, nothing else.

You can use ffmpeg.

Download ffmpeg( http://ffmpeg.zeranoe.com/builds/win32/static/ and choose a recent build). Put the ffmpeg.exe in same folder as your files.

Open notepad and put the following text

for %%a in ("*.avi") do ffmpeg -i "%%~na.wav" -i "%%~na.avi" -acodec copy -vcodec copy "newfiles\%%~na.avi"
pause

and save as it batch.bat. Be sure to select save as and choose all files under save as type.

Create a folder newfiles in same folder as your avi files.
Double click on the batch.bat
You will see if you get any errors.

Try first with a just one avi and wav file in a folder and see how it works.


edit: I have made a detailed ffmpeg batch guide also: https://forum.videohelp.com/threads/356314-How-to-batch-convert-and-multiplex-any-files-with-ffmpeg

Thank you for your answer. I will try it when i go home.

[Baldrick]

Let me know if it works...or not.

You can use ffmpeg.

Nice use of ~n expansion, I learnt something today.

It might be safer to quote filenames on the command line also, i.e.

for %%a in ("*.avi") do ffmpeg -i "%%~na.wav" -i "%%~na.avi" -acodec copy -vcodec copy newfiles\"%%~na.avi"

Cheers,

Yep, it strips the extension. Very useful.

THanks for the quote tips. Or else wont it work with files with spaces in the name. Updating the guide.

[MindController]

Wow. Thanks for this. I wasn't quite sure where to start with ffmpeg before.

[yken]

Thanks very much. It worked without any problem. I was looking for such a solution to automate it. Thanks again.
Now i need to convert all of these AVI files to any format. These are more than 300 gb broadcast files. Its too much 300 gb.
How can i convert these files to divx or mwv automatically? Can you help me again please?

[Baldrick]

You could also convert directly in fffmpeg. But it's easier to use a gui-application with batch convert support like xmedia recode, video to video converter, etc.

But give more details about the source files(use mediainfo, open avi, view->text and copy everything) and how much you would like to compress them.

[DarrellS]

You don't need to run the bat file from a command prompt. just run the .bat file.



Put the bat file and ffmpeg in the "Newfolder" and double click the bat file.

for %%a in ("*.avi") do ffmpeg -i "%%~na.wav" -i "%%~na.avi" -acodec copy -vcodec copy "C:\newfolder\newfiles\%%~na.avi"

if would be better if the newfile folder was not in the newfolder. Then you could put a copy of the bat file and ffmpeg in any folder with avi and wav and run it.

for %%a in ("*.avi") do ffmpeg -i "%%~na.wav" -i "%%~na.avi"  -acodec copy -vcodec copy "C:\newfiles\%%~na.avi"

That's all you have to do is put in quotes? So I've been changing the file names for nothing? It's no problem since I use a script to change folders at a time but...

Here is the file info. I have enough space, good quality is fine for me.

You don't need to run the bat file from a command prompt. just run the .bat file.

But you will miss all the errors then....if any. BUt you could add a pause to the batch and it will work. Good idea!..

Your source is interlaced....if you want it in avi divx/xvid or mp4/mkv h264 you should deinterlace it. I'm no deinterlace expert so I can't recommend the best convert method. Maybe you should make a new thread for the avi dvcpro to divx conversion.

if would be better if the newfile folder was not in the newfolder. Then you could put a copy of the bat file and ffmpeg in any folder with avi and wav and run it.

for %%a in ("*.avi") do ffmpeg -i "%%~na.wav" -i "%%~na.avi"  -acodec copy -vcodec copy "C:\newfiles\%%~na.avi"

And put the ffmpeg c:\ffmpeg and you will never have to copy it around also.

for %%a in ("*.avi") do c:\ffmpeg\ffmpeg -i "%%~na.wav" -i "%%~na.avi"  -acodec copy -vcodec copy "C:\newfiles\%%~na.avi"

Updating the guide with some tips. Thanks.

Thanks for that tip. I have copies of ffmpeg all over my hard drives.

How do you add the pause command? I tried yesterday when I was getting errors and counldn't do a screen capture fast enough to see the errors.

[Baldrick]

Just add pause

like

for %%a in ("*.avi") do c:\ffmpeg\ffmpeg -i "%%~na.wav" -i "%%~na.avi"  -acodec copy -vcodec copy "C:\newfiles\%%~na.avi"
pause

[DarrellS]

OK. It goes on a separate line. I put it at the end.
