Audacity is particularly useful for a language teacher to create audio resources for language learning.

== Creating video resources using your video recorder (on your mobile phone) ==
 +
You can record a video clip using your mobile phone itself, using the camera on the phone. While recording the video, take care to ensure that you are not shooting copyright materials or private spaces. You can copy the video file from your phone to your computer for editing and re-mixing to create OER.
 +
 +
== Creating a video resource using a screen-casting tool (''RecordMyDesktop'') ==
 +
Screen casting is also a very simple yet powerful way of creating a video resource. The recordmydesktop software records the computer output display as the video and audio. Additional audio spoken or played during the recording is also recorded as a part of the video.
 +
 +
Applications →  Sound & Video →  RecordMyDesktop

 +
 +
You can use recordmydesktop to create videos OER.  Make sure you are not displaying copyright material on the screen when recording the video. If you record any copyright material in the video, it will be a copyright violation.
 +
 +
=== Configuring recordmydesktop ===
 +
The better the quality of video and audio, the bigger will be the size of recorded file. You can adjust video and audio quality (and consequently size of the output video file) by adjusting the slider near the top right of this window. (Tip - Video Quality of 50% is good enough for most purposes and will keep file size lower).

=== '''Recording part of the screen''' ===
 +
'''Select window:''' You can also select the window to record, click on select window, then it will ask you to grab the area to select. You can select only that part of the screen that you want to record. This is useful if you are opening photos or playing a video on only part of your screen and want to record that part only.

=== Recording ===
 +
When you click on RECORD button, desktop recording will start

 +
 +
The recording can be paused and resumed at any time, by right clicking on the RecordMyDesktop icon in the top panel and selecting Pause (and Resume). Clicking on ‘Stop’ will stop the recording and initiate the export of the video output.
 +
 +
We need to wait till the export is completed, to get the output file. If we close the process before, we will lose the output file. The output file will be saved in your "HOME" folder by default with .OGV format. The file will usually have a name like ‘out.ogv’, however you can use the ‘save as’ button on the recordmydesktop screen to give a file name.

 +
 +
As a teacher, one of the ways you can make resources is to use recordmydesktop to create a video file by combining your voice narration with a set of slides or pictures or a video (or a combination of these) on your screen. You can simply play a slideshow of your slide presentations or images in your folder, or a video, recording these through recordmydeskop and providing the audio with your explanation / lecture. This can be used to create lessons for reinforcing learning or for students who have missed a class, to catch up.
 +
 +
=== Dubbing a video ===
 +
You can use this tool to provide voice dubbing for a video. For instance, you may find many OER videos in American English and you may want to change the language of narration to your own native language, to make the video more useful to your students.
 +
 +
You should to prepare the script for your narration in the language you want to dub the video in.
 +
 +
You need to set the sound settings on your computer to ‘mute’ (no output). Then start recordmydesktop application and play the video. As the video plays, read out your script. The audio read out by you will be combined with the video being shown on the screen to create the video in your language.
 +
 +
''We have taken a video of a teacher speaking in Kannada about a program he has been a part of, and dubbed it in English.''
 +
 +
<nowiki>**</nowiki> Video – Original video in Kannada and dubbed video in English
 +
 +
You could try this with any OER video you like, which is in accented English spoken in the USA or UK and dub it with your own voice, in English or your native language.
 +
 +
== Editing video resources using video editor (OpenShot). ==
 +
You can use OpenShot video editor to edit your video clips. OpenShot is a simple yet powerful application for video editing.
 +
 +
Open OpenShot on your computer, through Applications → Sound and Video → OpenShot
 +
 +
Image - COL - Video editing using Openshot
 +
 +
We will need to ‘import’ the video we have into OpenShot. You can also import photos and audio files and combine images, audio and video files to create a video output.
 +
 +
Import your video into OpenShot through File → Open  and select your video file
 +
 +

 +
 +
You should also import your video clip which you want to edit. You can add tracks to the OpenShot project.
 +
 +
This software is very powerful with many sophisticated features (for advanced features, refer to the user manual and tutorials, provided in Annexure) . However, we will learn a few commonly used functions, in video editing, which are useful to teachers in creating and re-purposing OER:
 +
# Moving (cut and paste of) a selection of video
 +
# Adding a slide (this can be used for sub-titling as well)
 +
# Adding a transition
 +
 +
=== Moving (cut and paste of) a selection of video ===
 +
Just like you can cut (or copy) paste a selection of text in a text document, you can cut (copy) and paste a selection of video in an video file. You can use this function to remove any part of the video clip you do not want. You can move a part of a clip from one place to another (for instance if you want to re-order responses in an interview). You can also delete a part of the clip also using the same functionality.

 +
Image – copying or moving a selection of the video file
 +
 +
=== Adding a slide (this can be used for sub-titling as well) ===
 +
Subtitling existing videos
 +
 +
Sub-titles or or provide your native language text as sub-titles
 +
 +
=== Adding a transition ===
 +
 +
== Inserting links to audio and video resources in a text document (''LibreOffice Writer'') ==
 +
 +
== Inserting links in a ‘slide presentation’ format (''LibreOffice Impress'') ==
 +
 +
=== Alternative applications - audio ===
 +
'''Ocenaudio''' and '''Wavosaur''' are alternative FOSS audio editors
 +
 +
=== Alternative applications - video ===
 +
'''SimpleScreenRecorder''' and '''Kazam''' are alternative screen recorders on GNU/Linux
 +
 +
Kdenlive is a sophisticated video editing software application on GNU/Linux.
