Hello and welcome to alugha. Today, I'll give you a quick tip how to merge an audio and video file.
0:09 → 0:17
Here's the problem: We got some users who keep asking us how they can download a video in a different language.
0:18 → 0:25
Theoretically that's not possible with alugha, but there is a very simple workaround.
0:25 → 0:28
If you got a video, like this one for example,
0:28 → 0:34
and this video is originally in German, so here it is German on YouTube.
0:38 → 0:41
And now you used alugha to add English to the video.
0:45 → 0:49
Then you can do the following: go to the dubbr,
0:50 → 0:55
you can see there, I created all my tracks, recorded the audio for them
0:55 → 1:01
and now I want to merge the English audio with the video.
1:01 → 1:07
Go to the tab of the language you want to download; here's the audio.
1:10 → 1:19
This is the completely finished audio mixed together by alugha, which you can also hear on your video.
1:19 → 1:21
Click here
1:22 → 1:27
to download the audio file, alugha_export_Samsung_eng.
1:28 → 1:32
If you have the video on your computer
1:32 → 1:38
and have downloaded the new audio in the new language, open a command prompt.
1:39 → 1:43
To do all this, I use a tool called FFmpeg.
1:43 → 1:48
It's free, open source, available for many operating systems, there's a link down below.
1:48 → 1:57
So, once you've installed it, ffmpeg -i , that's my input, so my Samsung video,
1:57 → 2:02
-an -vcodec copy,
2:02 → 2:09
now I do the following: Samsung_NoAudio.mp4
2:10 → 2:14
I now create a video with no audio from the existing video.
2:14 → 2:18
So, I've removed the audio from the video.
2:18 → 2:22
Which means, when I go back now and play the video,
2:23 → 2:25
you won't hear anything.
2:25 → 2:33
And now I'm going to merge an audio file with the video again, which I'll do as follows:
2:33 → 2:40
Go back here, ffmpeg, my input file is now my Samsung_NoAudio
2:40 → 2:49
and my audio input file is my alugha_export_Samsung_eng.
2:49 → 2:59
Then -c:v copy -c:a aac, in my case,
2:59 → 3:07
and I'm going to name it Samsung_ENG_final.mp4.
3:07 → 3:11
Now it copies the audio into my video.
3:15 → 3:20
And now, if you want to, you can upload this video to any other platform.
3:20 → 3:25
You don't need an extra tool, we don't need an extra server to render it,
3:25 → 3:29
because you already have the video file and the audio file, so it's super easy.
3:29 → 3:35
Of course, you can also use video editing software to do this, but if you want to do it quickly, FFmpeg is a great option.
