    Replacing audio with movie maker


    I want to replace the audio at only a particular place in my video. I have gone through the tutorial that first go to edit tab and the click the video volume button and move the slider to the left (mute the original audio) and then add new audio at the current place. My doubt is that will it replace the audio at the current place and will mute audio in all the video. I do not want to mute whole video but only want to change the audio at a particular place. Please advise.

    What version of Movie Maker do you have? I have Movie Maker 2012, but these instructions should apply to other versions too.

    To mute the sound in just one section of the video you first have to mark the start and end of the section you want to mute. To do this, play the video and pause at the start of the section to be muted. On the Edit tab click Split. Now play to the end of the section to mute and pause there. Click Split again.

    You now have a small section of the video you can click on to select. When you move the volume slider it applies just to this selected section.

    ...add new audio at the current place. My doubt is that will it replace the audio at the current place...
    When you add new music it doesn't replace the existing audio, it add a second audio track alongside the existing one. The volume of each audio track can be adjusted independently to get the effect you want before exporting the finished video with the audio tracks combined as one.

    Thanks Bree,

    Actually I have already started by hit and trial and already more than an hour has passed and it is only 20% finished and I do not know whether the finished video will be the one which I require. Anyway it is too time consuming.

    Though it will be out of the present context but I know you helped me earlier with ffmpeg. Can you help me and tell me the command to replace audio in my video with ffmpeg. I want to replace audio at different places e.g (1hour 40 minutes 30 seconds to 1 hour 43 minutes 12 seconds) and second at (1 hour 52 minutes 15 seconds to 1 hour 55 minutes 10 seconds) and so on. If it could be done in one go or multiple. Thanks

    I'm not sure if it's possible to specify replacing parts of the audio using FFmpeg (I suspect not). What I do is extract the audio track, edit it using Audacity, then replace the whole original audio track with my edited version. The commands I use are...

    FFmpeg -i original.mp4 original.mp3

    ...edit original.mp3 in Audacity and export finished result to edited.mp3, then...

    FFmpeg -i original.mp4 -i edited.mp3 -map 0:0 -map 1:0 -c:v copy new.mp4

    FFmpeg take the two input files and maps file0:stream0 (the original video) to stream 0 of the output, and file1: stream0 (the edited audio) to stream 1 of the output. The -c:v copy means that the video will not be recoded but copied directly from the original so that you don't loose any quality.

    Thanks for clarifying. I think, it will not be possible for me to go through all this. May be someone give some other advise to replace audio at certain part of the video with fast output.

    The FFmpeg I gave are fast because there's no video codec processing involved.

    It is fast but to first extract all audio (wherein I want to replace a part) and then make changes with Audacity and then again incorporate it in the video are many steps involved. Is there any easy standalone software, as I don not want to touch all the audio because I know I will certainly make a mess.

    AVS Video converter, AVS Video Editor & AVS Video ReMaker works great.

    Whether it does the expected job without rencoding.

    Is it free. Because for one or two video, I am not going to buy the software.

The -c:v copy means that the video will not be recoded but copied directly from the original so that you don't loose any quality.
    Q1 The first command "FFmpeg -i original.mp4 original.mp3" simply figures out that it copying the audio and not data merely by the fact that the output file name ends with mp3? I tried it it works and it converted from 96kbs to 64bits mp3 using lame. Is this conversion of kbp automatically based on matching quality or a default? Normally you want to simply use similar level of compression or not convert and simply copy - not possible in this example as ac and mp3 are different i guess? Any tips on options on extracting as close to original or keeping it same.

    Q2) in the second example, again my mp3 file got converted to a different kbs - how would one ask that simply copied as is. add a -c:a copy? Does .mp4 allow the audio to be mp3 format or does it require ac?
