Hi, i used ffmpeg to quicky convert audio formt only in a video.
But, after conversion, i coud not find the location of converted file, as i could not find it in the source file folder.
any one has idea about it
could you say the formula for permanently removing the hard coded subtitles in a video in ffmpeg
ffmpeg......example would be helpful

It should be in the same folder as ffmpeg. (The one which you CD to in Command Prompt)
Check for the output name used in your ffmpeg command.
AFAIK ffmpeg cannot be used to remove hard-coded subs.
You can use it to burn a blank sub box over the existing subs obscuring them.
You could also probably use it to crop the screen size removing the subs (with some of the picture!!)
I'm pretty certain it can't simply remove the hardcoded subs. Although, I'd be pleased to hear otherwise.
You can always use a full path for the output file to put it exactly where you want it.
Some people prefer to use a in-filled box with the delogo filter, instead of a black box to cover the subs, or cropping to remove them:
"G:\Program Files\ffmpeg\bin\ffmpeg.exe" -i %1 -vf delogo=x=251:y=650:w=800:h=50 -c:a aac -b:a 192k %1.delogo.mkv
Your quote:in-filled box with the delogo filter
, which software has this feature, i mean xy top left, and wh parameters. Trial does not cast much things to loose
should i run your code or should i copy with my files But i just use ffmpeg command to get the output.
which is the default location of the output file, this is the query
Normally a program copies output , in a folder of its existence or ask us to check.
there shoud be a default folder where the output files would reside.
i could not find the output in the same folder.
Hi, i am having windows 7 ultimate. Could you say the output folder now
It should be in the same folder as ffmpeg.
Are you sure you are producing an output file?
What code are you using?
I haven't tried your code but I think it needs a copy command.
I assume you're trying to map a new audio track into an existing mp4. Use this;
ffmpeg -i input.mp4 -i new.mp3 -c copy -map 0:v:0 -map 1:a:0 output.mp4
ffmpeg -i input.mp4 -vn -acodec copy output.aac
Here's a short video with the logo removed with that batch file:

This is very good site dedicated for answering questions like yours: https://ss64.com/nt/syntax-variables.html
Also i highly recommends Rob van der Woude site:https://www.robvanderwoude.com/ - full of precious knowledge!
after much search, i found the output file
in c:\user\username\appdata\local\virdual drive\program files\ffmpeg\bin
It has taken lot oftrials to find this path
i already enabled path variables to this ffmpeg, but somehow it does not work.
so i copied the file itself to the bin driectory , in the extracted folder.
ffmpeg -i input.mp4 -acodec mp3 output.mp4 aso processed , but it takes much time and the speed is 2.5
ffmpeg -i input.mp4 -acodec mp3 -vcodec copy output.mp4
this formula the audio change is effected within a few minutes at speed of 32.7 mear
what is the difference
this formula i copied from net surfing
Now i found out the output folder, this trick may be useful for some one who has my problem in locating the output file
One more query:
the changed audio codec is mpeg audio 1/2(mpga) and not mp3
Is the conversion would support a kind of mp3 format, which is supported by my tv for playing
my tv does not support m4a audio,
i want answers to two queries raised here
thanks for all for helping
Hi, diag, it is very interesting to know your formula contains some new things, could you kindly explain
my attempt is to just change audio codec to mp3 in a mp4 file .
Will your code work. what is the difference from extracting mp3 and creating a new mp3
i just want to change ithe audio format to mp3
i am not a programmer , so i ask this query
will try your batch file and report back.
how to create a box to hide the old one with black and insert my srt files scripts
i amnew to this forum and also to ffmpeg
Hi, jaga, i created a batch file with the same code , but i do not know how to drop and drop the mp4 file to this batch file.
the path is as you have written, but i am having the source file in the bin directory, and when i try to drag, it just opens with the swource file.
should i wait till the video runs and then see the same folder for new file
hope to get clues and replies diag and jaga
i just saved the code as txt, and that was the mistake
when i changed the same to bat, and drag and drop,
a progressing glass runs and my video file size is 225 mb
hope to get the output , after an hour or so
this is the progrogress
my attempt is to just change audio codec to mp3 in a mp4 file .
Ignore the copy command, it just copies the audio stream into a new mp4 container.
That's why it was quick.
Your original code should be correct. It re-encodes the audio to mp3 format.
The re-encoding can take a long time depending on the size of the file.
Thanks for your clarification on the slowness of command
Please kindly say, why it is compressing to mpeg audio layer 1/2 instead of mp3.
please say, if both are same.
Will i get lower audio quality if it converts to mpga, and i also do not know, if my tv supports it, as there was nothing like supported format in the TV manual
Next coming to the main issue,
when i drag and drop , it processed , but opens amachine language file, which when closes, vanished in to
Really i do not know the trick, to give or change the batch files.kindly say, how to go about it.
i already informed you that i am not a programmer.
i saw your sample video
where is the source file in your batch script
shere is the outpuyt is saved
why it is shown as an opened mp4 file in notebook text form
please reply quick\
the path i gave , please take the correct path as virtualstore instead of virtual drive
Audio ID : 2 Format : MPEG Audio Format version : Version 1 Format profile : Layer 3
ffmpeg is 128 kbps. With mp2 encoding it's 384 kbps. mp2 is probably better quality than mp3.

Hi, for your query on the program i use is , just ffmpeg command line
Please say, that the audio codec will be based on the video format?
As i copy the video file , in to the same folder where ffmpeg.exe resides. That is in the bin folder of ffmpeg in program files subfolder
So, there is no chance of error
please give me , how to go about giving width, height etc, if the subtitle position is , just in the middle of the botoom most of the video as usual in any video.
I will try with pause command.
Is it correct, that if i just drag, the cursor becomes a glass of progress, and had to wait till it closes. When it closes, i found a mahine text file,with mp4 extension stay opened and when i just closed it, it closed.
Thanks for all learning from this forum
expecting your reply
Regarding the virualstore errata, i have given the path of the output file in my window 7 pc. i iyped virtualstore as virtual drive inadvertantly

Hi, i am enclosing the notepad file , as processed by the bat file
May be i am wronly given the height and width
any how, i am enclosing for your analysis , hi, jaga
Hi,the file size is 1.9 mb, so , i just cropped it to show you a kind of output
Last edited by jraju; 9th Oct 2019 at 09:03.
when i drag the file in to the batch file, no cmd prompt opens, instead a progressive glass opens and give result as in my above example, in not readbale lanaguage .
what i am missing jaga
for your information, the input file is selected from the ffmpeg,bin folder where i stored the ffmpeg.exe
Moreover, if i include a clear mp3 audio codec for conversion ,thro ffmpeg, my file is converted to mpga format
But you say, that it converts to correct mp3.
i think that i have got the latest version of ffmpeg
for making the ffmpeg work, i go to the installed folder thro command prompt, using cd command to execulte the ffmpeg.exe
why i am getting undefined output instead of cmd and processing output
When i just execute bat file i get this result

Something is wrong with the batch file. But the first few lines aren't visible in your screen shot. Right click on the batch file, select Send To -> Compressed (Zip) Folder. Then upload the zip file attached to a post here.
i aleady told that i do not know how to change the h w etc
I just used your bat file , except changing the drive from G to C:
enclosing the zip file for your easy reference
Your batch file looks ok as long as the path to ffmpeg.exe is correct. You should be able to drag/drop any video file onto the batch file to produce a new file with the logo removed. The CMD window that opens should look like:

Hi, i say the same thing. i have used only that bat file. When i drag a video to that notepad opened file, i keep the file open to drag and frop the video file.
When i drag, the pointer becomes a explorer search like processing, with non responding message. The letters in the batch file is also missing after a few seconds.
Should i just double click your bat file and then drag and drop the video
i am in the edit mode, when i am drag the file. is that incorrect
or should i execute the bat and then in the command window, i should drag the file
There is something missing please guide. If this works, then i will try changing the parameters of xywh etc
i understand now. i thought that if i have to drag the file , i should have open window.
Your batch file when executed procduce a mkv output , with the name inlucded as , outputone.mp4.delogoone.mkv.
tthe execution is a flash of a second.
but , it is having only 0 bites.
There is no error message, whatsover
where i am missing
