how to add audio to existing video using FFMPEG at specific time?

Question

I have video file (.avi) that contain video of 10 minutes. I also have audio file (.wav) that contain 1 minute of sound.

I need to add the audio to the exist video but the audio need to start at after one minute of the video

How to do it ?

( prefer using ffmpeg if its possible )

try already this query ( 30 seconds delay )

-i video.avi -i audio.wav -filter_complex \"[1]adelay=30000|30000[aud];[0][aud]amix\" - c:v copy out.avi"

Attached the log of ffmpeg when trying to merge more then one wav:

Podium

I found how to add the audio on the start of the video ( simple Concatenate and its work ) - but i need to move the audio 1 minute foreword – Podium

Answer 1

Use

ffmpeg -i in.avi -i audio.wav -filter_complex
"[1]adelay=62000|62000[aud];[0][aud]amix" -c:v copy out.avi

The adelay delays the start of the WAV by 62000 milliseconds for all channels, assuming 2 channels in the WAV and then that is mixed with the video's audio.

---

To mix two audio files,

ffmpeg -i in.avi -i audio1.wav -i audio2.wav -filter_complex
"[1]adelay=30000|30000[aud1];[2]adelay=90000|90000[aud2];
 [0][aud1][aud2]amix=3" -c:v copy out.avi

I wrote what you said - but still does not work ( 30 seconds deley ) wrote embedded in the question the query – Podium

Show the full log. – Boatman

sorry ... where can i find the log ? ( i new in ffmpeg world :( ) – Podium

i add the log embedded – Podium

That's for a different command, which happens to be malformed: ffmpeg.exe -report -i "video.avi" -i "555.wav" -filter_complex "adelay=20000" - c:v copy "OUT.avi" – Boatman

now its work - but ffmpeg add the wav into two places :: 1. at the start of the video 2)after 20 seconds. I don't want to add it to the start - only after 20 seconds. – Podium

Because you provided only one adelay value. It should be 20000|20000 – Boatman

is it possible to do it without copy to new file ? i mean to do it on the original video file – Podium

ok - but if i have 2 wav files = that the first need to start at 30 seconds delay and the second need to start at 90 seconds delay .. ( each of them has length of 10 seconds ) -- how to add them to the same video file ( new file that contain both of them ) i try to run loop that add them using the query above - but only one of them added – Podium

I add new ffmpeg log when i trying to marge more then one wav file - i get error – Podium

ffmpeg.exe -i "..\\merged.avi" -i "Storage\\1.wav" -i "Storage\\2.wav" -i "Storage\\3.wav" -filter_complex "[1]adelay=30000|30000[a1];[2]adelay=91000|91000[a2];[3]adelay=151000|151000[a3];[0][a1][a2][a3]amix=4" -c:v copy "Storage\\ALL.AVI" – Boatman

now, when the audio files are 30 seconds for each ( total 1 minute ) and the video is 4 minute -- then the video output is cut to 1 mimute and does not keep the original size how to solve this ? – Podium

Answer 2

Here's how, let's see if they change the code and don't invest in companies that pay employees that would build it all.

ffmpeg -y -i video.mp4 -i 002.ogg.mp3 -i 003.ogg.mp3 -i 004.ogg.mp3 -filter_complex "[1]adelay=1000[s1];[2]adelay=2500[s2];[3]adelay=4000[s3];[s1][s2][s3]amix=3[a]" -map 0:v -map "[a]" -preset ultrafast video_with_audio.mp4

It's easy to figure out, filter_complex accepts commands as arguments sequentially and assigns variable names that can be used later in the series with the last being the command that mixes everything.

Answer 3

I am very sure you have failed to add 'a' to 'v' testing/applying all of your search so far.

Adding audio to video is not simple as 1-2-3. Read carefully. (a= Audio, v= Video, ta= Temporary Audio File, v.position= video file's position in mil. sec.)

If you are not able to understand below, you can simply discard your method in your project, regarding 'add a to v'. There will be not much difference doing so.

/////////////////// Big Picture ///////////////////

1. Check if 'v' has any 'a'. (out of topic).
2. If 'v' has 'a', extract 'a' from 'v', and save 'a' as 'ta'. (out of topic).
3. If 'v' does not have any 'a', collect all inserting 'a's. (out of topic).
4. Find insertion position in sec. in 'v' to insert 'a' (dynamic insertion postion upto the application). If 'a's duration exceeds the duration of the 'v' at the insertion positon, trim 'a'. (out of topic).
5. Make sure 'mix all audios' before applying to the 'v'. (out of topic).

If 'a' is not properly trimed, 'v' will play even after the 'v's duration. (out of topic).

///////////// Now back to the topic. ///////////////

Following adds [a1.aac] at v.position 0 sec., and adds [a2.m4a] at v.position 1 sec. [adelay=] must follow as [adelay=milSec.|milSec.]. [amix=2] => mixing 2 audios. Replace # with 3 in [amix=#] if you are mixing 3 audios. One of the input 'a' can be 'ta' = [Temporary Audio File] by extracting 'a' from 'v'.

ffmpeg -i v.mp4 -i a1.aac -i a2.m4a -filter_complex "[1]adelay=0|0[a1];[2]adelay=1000|1000[a2];[a1][a2]amix=2[a]" -map 0:v -map "[a]" -y output.mp4

If adding 'a' to 'v', which does not have any 'a', pass -filter_complex "[1]adelay=v.position|v.position[a1]" -map 0:v -map "[a1]" -y output.mp4.

Please do not ask me any 'out of topic' issue.

Thanks,

Menken
