Stage 2
Dubbing Instructions
- Before dubbing, go through the tutorial on "How to use Audacity and ffmpeg" on our website. This is available under the FOSS category Spoken Tutorial Technology
- Once again follow all the tips given in Guidelines on Narration
- View the original tutorial
- Make a note of the begin time of each sentence in the original

For more details, please watch "How to use Audacity and ffmpeg" - Do this till all the audio clips are placed at the noted time intervals
- Play the whole movie back and confirm that the dubbed audio and video are in sync
- Save the movie as per the instructions given in "How to use Audacity and ffmpeg"
- Review the resultant movie against the Dubbers' Checklist and make the required modifications
- Intimate your IITB Team Leader on completion of this stage or write to [administrator@spoken-tutorial.org]. Here is what we will check
Conversion Instructions
Step 1
- We recommend that you dub/record using Audacity
- (It is available for all OS : Linux Distributions, Windows [all versions] and also for Mac OSX)
- After you record in Audacity -
- Click on File -> Export -> save as *.mp3
- This will export the final audio as an "*.mp3" file
- If you are using Movie Maker -
- Convert the output file as an "*.mp3" using Any Video Convertor (Free Version)
Step 2
- Now download the original ".mov" English video from this link http://spoken-tutorial.org/english-videos
- Place the dubbed audio file (.mp3 format) and the downloaded English video file (.mov format) in the same folder
- Please Note - You have to use FFmpeg Command Line for the following process
- So ensure that it is installed on your machine
- Do the following in a Linux machine -
- Open the Terminal and go to the folder using cd command
- For e.g. cd Desktop/linux
- Here linux is the folder in which I have saved the audio and video files for conversion
- In my case, the file names are :
- English Video : linux-basic-of-syatem-admin-english.mov
- Dubbed Audio : linux-basic-of-syatem-admin-tamil-dubbed.mp3
Step 3
- First : Remove the English audio from the downloaded English mov video
- To do so, type the command :
- ffmpeg -i linux-basic-of-syatem-admin-english.mov -an -vcodec copy linux-basic-of-system-admin-english-video-without-audio.mov
- This command will remove the audio from the input video (linux-basic-of-syatem-admin-english.mov) and
- save the output video (linux-basic-of-system-admin-english-video-without-audio.mov) in mov format itself
- Second : Merge the dubbed audio with the English video without audio
- Type the command :
- ffmpeg -i linux-basic-of-system-admin-english-video-without-audio.mov -i linux-basic-of-syatem-admin-tamil-dubbed.mp3 -vcodec copy -acodec copy linux-basic-of-system-admin-tamil.mov
- This command will merge the dubbed audio (in .mp3 format) with the English video with out audio (in .mov format) and
- save the output in .mov format (linux-basic-of-system-admin-tamil.mov)
Step 4
- Convert the dubbed mov file into ogv video
- We have the dubbed video in .mov format with the same quality like the original English video
- But we need it in .ogv format
- To convert mov into an ogv video, use a Firefox add-on called Firefogg
- We have to use the latest version of Firefox Web browser (Firefox version 5 and above)
- Click on this link Firefogg to add this add-on into our Firefox Web browser
- Follow the steps shown and install Firefogg
- Now, we can convert our videos into ogv videos
- Open Firefox
- Click on Tools -> Make Web Video
- This will open the firefogg conversion process in a new tab
- Click on the Select File option
- Browse the File
- After selection the file, it direct to file format/preset page. Click on Advance Options
- In the advance settings page,
- Click on Encode
- It will prompt you for the location to save the output video
- So, choose the location where you want to save
- Also confirm that it is saving in ogv format and click on Save
- The conversion process will take some time
- After the conversion is over, it will show the preview of the converted ogv video
So finally we will get the dubbed video in OGV format in GOOD QUALITY with LESSER FILE SIZE
