= Lab =
This is a marked lab. Please submit it using Moodle (Lab5).
== Shoot a video ==
* Have a look at the video ports available on your laptop, or your desktop, or the lab machines. Note that Apple likes to have their own versions of connectors. Make a list of the ports, what types of ports they are.
* If you cellphone/camera can shoot video - make a short one , probably 30 seconds, just showing the video ports on your machine. If you don't have one - you can borrow mine. == Simple editing == This is very basic movie editing, and professionals will laugh if you say you edited a movie with this tool, but it`s a good set of basic skills to have. * Use the windows live movie maker to create a new project.* Add the video you shot to your project.* Save the project, note that the project file is very small and does not include the video file.* Add a title screen with your name, date, and the machine you`ve shot the video of.* Add a transition effect between the title screen and the video.* Add some subtitles, naming the ports that are beeing displayed in the center of the video at any given time.* Save the movie as "ports.wmv" using any of the options. Try to find a way to keep the file small, it has to be under 10MB for Moodle to accept it. == Format coversions == * Download the free Prism video file converter from NCH sotware and install it.* Set the video to shrink to a smaller size (640x480 or 640x360 depending on whether your video was widescreen to begin with).* Use it to convert your ports.wmv to ports.3gp using the H.263 codec.* Use it to convert your ports.wmv to ports.mp4 using the H.264 codec.* Use it to convert your ports.wmv to ports.gif, this will be an simple animated gif. This one will obviously not have any sound (and will be an animated image, not a video). * Download the free Miro Video Converter and install it.* Convert your video to ports.ogg* Convert your video to ports.webm == Video on the web == This part is very similar to the audio part you`ve done last week but now you use video instead. * Make an html page with a table, and in each file have cells for:** The container (extension) and codec** The size of the file** An html <video> tag with that file, except for the gif.** List of browsers where the video did and did not play.* Try it in at least 3 different browsers. == Submit == You have to submit:
