=='''What should we do after we dub the audio?'''==

==='''Do the following to submit an ''.ogv'' video with a good video quality and less file size '''===
===='''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'''====
#After that '''download the original ".mov" English video from this link'''  [http://spoken-tutorial.org/english-videos 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 that, you have to use '' [http://ffmpeg.org 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
#: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 [http://firefogg.org/ 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
##:[[File:Firefogg-1.png|400px]]
## Browse the File
##:[[File:Firefogg-2.png|400px]]
## After selection the file, it direct to file format/preset page. Click on '''Advance Options'''
##:[[File:Firefogg-3.png|400px]]
## In the advance settings page, 
##*Change the '''Format as Ogg(Theora/Vorbis)''' 
##*Set '''Audio Quality as 5'''
##*:
[[File:Firefogg-4.png|400px]]
## 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'''
##:[[File:Firefogg-5.png|400px]]
## The conversion process will take some time
##:[[File:Firefogg-6.png|400px]]
## After the conversion is over, it will show the preview of the converted ogv video
##:[[File:Firefogg-7.png|400px]]

   So finally we will get the dubbed video in '''OGV format''' in '''GOOD QUALITY''' with '''LESSER FILE SIZE'''
   Note that, the video filename should be submitted with proper Naming Convention as shown below :
   foss-name-level-topic-name-language.ogv (linux-basic-basics-of-syatem-admin-tamil.ogv)
