4. Who is talking in the Video


If you want to add a short intro video of yourself (1min-2min), use the webcam and store the video as file on your computer (e.g. as MPEG4 Video video0.m4v or video0.wmv). It makes the video more personal and people have an impression, who presents the slides (important for virtual AT6FUI conferences). A personal short introduction is not necessary for the video presentation. Creating a video presentation with slides follows on all operating systems the following principles.

  1. Software for Video Editing and Movie Creation has a timeline with Audio and Video Tracks.
  2. You can place real video on the track by importing the introduction video and the images of the slides
  3. The introduction video recorded from the webcam can just be inserted by drag and drop on the timeline in most Video Editing Software
  4. The Slides will also be dragged and dropped on the timeline and the display length has to be changed to lenght of the audio files.
  5. After finishing the presentation render the video to a format that is capable to upload to the Spatial Public Health YouTube Channel.
HD-Videos are limited to 2GB file size and 15min length. For offline presentations and downloads as capacity building material, please keep the files small especially when people have poor internet connectivity. You can download the YouTube Video e.g. with VideoDownloadHelper Plugin for Firefox (Firefox OpenSource Browser).

If you need more support, use YouTube Screencast Videos:
