Creating videos on the Mac OS/X

• Modern MacBook have a high resolution which prevents you to make a movie with your full screen: you need to choose a smaller window (or to alter the resolution) if you want that people read all your writings or legends that appear in a standard software.
• QuickTime player 10 is very efficient and free (with the Mac OS/X) tool.

• QuickTime player 10 lets you have a small windows with your face as seen by the Isight web cam. It might be unnecessary but for most people it helps understanding while keeping the attention of the viewer. A short video could explains how to do it by File => New video recording.
• In a second step you can record a selected area of your screen by File => New screen recording. You must include the previous Isight view in your selected area. The area of the screen which won't be selected for recording is grey. When you click on the central "Start recording" button, your video will record your activity within the selected area by emphasizing you keyboard and mouse click as well as your voice.
• When you are finished recording click on "finish recording".
• The file created can be "edited" by QuickTime player in the sense that a sequence can be visually selected and extract to a new video file.
• Files have an extension .mov which are h264 for the video as well as mp4a stereo for the audio.

QuickTime player lets you publish your video on Youtube but the size and thus resolution of Youtube videos are usually to small.

Mediawiki software have a few extensions which let you display some video formats but they are not powerful at all. The ogghandler extension has been used for years by Wikipedia both for audio files (.ogg) as well as theora video (.ogv). Thumb video are created on the fly in some specific formats.

In order to create .ogv file ready for uploading you need to use a software (GPL) name ffmpeg2theora. The advantage of an ogv file is that it includes metadata like the license:

ffmpeg2theora --artist "Nicolas Brouard" \
  --title "5c Adding references to the Population Open Encyclopedia" \
  --date "October 2012" --location "Paris" \
  --organization "Institut national d'études démographiques" \
  --copyright "INED" --license "Creative Common Share Alike" \
  --contact "contact@demopaedia.org" 5c\ Adding\ references\ to\ the\ POE.mov

Then, you can upload your video to demopaedia.org: there are two different servers for uploading as well as serving videos and audio files:

1. commondics.demopaedia.org is reserved for files related to the Multilingual Demographic Dictionaries (all the voice recorded audio files of each TextTerm are here).
2. commons.demopaedia.org will be used as commons.wikimedia.org for any media file related to the Population Open Encyclopedia.

For media files, there are less reasons to have a server for each language and that is the reason for a common server.

The right for uploading files to each server are depending on your login group.

When uploading a video, use the upload facility of commons or commondics. A video on commons or commondics can be transcluded on any demopaedia server.

Currently, the videos related to the Multilingual Demographic Dictionary can be accessed from en-ii:Demopaedia:Videos even if the files are on commondics.
