Designing video based learning
It is easy to shoot a video with the latest cameras, mobile phones and other gadgets and share it online
by publishing on social media channels. However, effectiveness of video based content depends on a clear design and well thought out strategy for production and post-production - both synchronous and asynchronous. Watch this presentation to see how the Khan Academy is reinventing education with the help of videos. Some important points we need to consider here:

Extract from the book: Chapter ... (section on video based content development)
Video recording may not sound like it is specialised, because as amateurs we have recorded video from cameras,
mobile phones and other digital gadgets. When it is not done professionally, video may not be of the desirable quality
and format. To ensure quality output, video should be recorded under professional guidance, preferably in a studio.
In case this is not possible, the following parameters can serve as basic guidelines
Post production
Video files are compressed after editing for reducing the file and frame size. The frame size depends on the size of the window in which it will play. Since video files are large files because of the frame rate, a codec (compression and decompression) of the video is done without losing out on the quality aspects. Raw digital video in .avi or mpeg or
Quicktime format is imported into Flash and converted into .flv files. This can be played on the Web or packaged
as a CD or DVD or played from ‘YouTube’. These files are generally deployed on a streaming server to facilitate better download even at slow speeds. Proprietary tools like Adobe Premier and Presenter are used to edit and deliver video.
Synchronous development
In live or synchronous e-learning, the development and delivery take place almost simultaneously. This poses a different kind of challenge, since the presenter should be able to edit or modify the content ‘on the fly’ i.e, when a live session is in progress.
Here, the pre-production activities are of greater importance, since more time and effort are required for systematic planning and choice of tool for the delivery of the lecture or presentation. The presenter should be trained in using tools like Whiteboard and synchronous collaboration tools (See Chapter 9, section on virtual classroom). The presentation can be developed before the actual session by considering the following points:
