General Instructions
  1. Make sure that you have the required font installed on your computer
  2. We recommend that you use LibreOffice Writer to type your script
  3. Watch the video Typing in local languages in the LibreOffice Writer series on our website to know how to type in various Indian languages
  4. In LibreOffice Writer, the script should be typed in wiki-markup so that you can directly copy and paste it later
  5. To see a sample wiki-markup script, please visit English-Timed-script and do the following -
    1. Login to script-wiki, since you have an account there
    2. Click on the edit tab
    3. Now copy and paste the wiki-markup to your document in LibreOffice Writer
    4. Type your translated sentences in the Narration column part, as shown in the sample that you copied
Translation Instructions
  1. Watch the original English video, at least once, to understand the context of the script that you have to translate
  2. Use the English Timed-script of the selected topic
  3. Translate the script sentence by sentence in such a way that the meaning of the original tutorial is maintained
  4. Take enough care to see that each sentence when translated, takes same or lesser time to read out, than the original sentence
  5. In some cases, you may merge 2 sentences in the translation so as to match the timing of the original 2 sentences
  6. Use simple and precise words while translating
  7. All words that are in bold-face in the English Timed-Script should be retained in English itself. Do not translate these words. Just transliterate them.
  8. Retain common words like window, mouse, cursor, etc. in English. However, in the translated script, the English words should be transliterated.
    • For eg-
      • In Hindi ऑनलाइन (online), इनपुट (input), कमांड (command)
      • In Gujarati ઑનલાઇન (online), ઇનપુટ (input), કમાંડ (command)
      • In Tamil ஆன்லைன் (online), இன்புட் (input), கமாண்ட் (command)

Conversion Instructions
Step 1
  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)
  2. After you record in Audacity -
    • Click on File -> Export -> save as *.mp3
    • This will export the final audio as an "*.mp3" file
  3. If you are using Movie Maker -
    • Convert the output file as an "*.mp3" using Any Video Convertor (Free Version)
Step 2
  1. Now download the original ".mov" English video from this link http://spoken-tutorial.org/english-videos
  2. 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
  3. Do the following in a Linux machine -
    • Open the Terminal and go to the folder using cd command
    For e.g. cd Desktop/linux
  4. Here linux is the folder in which I have saved the audio and video files for conversion
    In my case, the file names are :
    1. English Video : linux-basic-of-syatem-admin-english.mov
    2. Dubbed Audio  : linux-basic-of-syatem-admin-tamil-dubbed.mp3
Step 3
  1. 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
  2. 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
  1. Convert the dubbed mov file into ogv video
    1. We have the dubbed video in .mov format with the same quality like the original English video
    2. But we need it in .ogv format
    3. To convert mov into an ogv video, use a Firefox add-on called Firefogg
    4. We have to use the latest version of Firefox Web browser (Firefox version 5 and above)
    5. Click on this link Firefogg to add this add-on into our Firefox Web browser
    6. Follow the steps shown and install Firefogg
  2. Now, we can convert our videos into ogv videos
    1. Open Firefox
    2. Click on Tools -> Make Web Video
    3. This will open the firefogg conversion process in a new tab
    4. Click on the Select File option
      Firefogg-1.png
    5. Browse the File
      Firefogg-2.png
    6. After selection the file, it direct to file format/preset page. Click on Advance Options
      Firefogg-3.png
    7. In the advance settings page,
      • Change the Format as Ogg(Theora/Vorbis)
      • Set Audio Quality as 5
        Firefogg-4.png
    8. Click on Encode
    9. It will prompt you for the location to save the output video
    10. So, choose the location where you want to save
    11. Also confirm that it is saving in ogv format and click on Save
      Firefogg-5.png
    12. The conversion process will take some time
      Firefogg-6.png
    13. After the conversion is over, it will show the preview of the converted ogv video
      Firefogg-7.png 
  So finally we will get the dubbed video in OGV format in GOOD QUALITY with LESSER FILE SIZE
