Week 2 topics - Create HTML5 videos
This week you will learn how to create an HTML5 page that includes an (HTML5) video that includes tracks (subtitle) and some custom interactivity.
Adobe CC installation (for later use)
To run the CC applications you need to
- Launch the "adobe Creative Cloud Packager" tool
- Click on Creative Cloud Desktop apps for education (be careful with this one, if you select entreprise you will end in an infinite loop)
- enter as a username your webster EDU email address (xxx@webster.edu)
- wait for the redirect and enter again the e-mail address + the connections password
- Once this is done, you can launch the CC apps
Monday
Presentation of HTML5 video technology and demo
- Wiki pages used:
- Understanding the HTML5
videoelement - Understanding tracks and the tracks element
Video convertors and editors
For this class, an online converter and trimmer can do: Try Cloud convert. However, be prepared to wait. TechRadar has a larger list.
Browser extensions
We recommend using browser extensions for simple tasks since they can be installed on any computer you use. They are often cross platform. However, some extensions include many advertisements and others can track your web navigation, so be a bit careful. Generally, we recommend using Firefox, since it's the only major open source browser. However, most useful extensions did disappear after version 56 (in 2017) and the browser did become less than half as useful as it used to be. You will find the extensions to the right of the URL bar.
Firefox Media converter and Muxer
- https://addons.mozilla.org/en-US/firefox/addon/media-conversion-tool/
- This works well, but requires extra installation work and administrator privileges (do not try this in the computer lab !)
Online tools
- Cloud convert. Converts and also can trim
Video converter for Windows
- Handbreak (Open source editor, also can crop. Output is only mp4.
- Freemake Video Converter
- Video Converter Factory
Video editors for Windows and Mac
- See Video editing and conversion, e.g. OpenShot and ShotCut. Both are multi-platform and require some learning. Some folks are happy with Avidemux.
- On older Windows systems, use Windows Movie Maker
- On a Mac, use IMovie
Hands on
- Create a short video that uses tracks. Make sure that the file size is small, i.e. use a fairly low resolution and make it short in time.
- A complete simple example is: http://tecfa.unige.ch/guides/html/html5-video/html5-video-track.html
- In case you cannot produce or find your own video, you can start playing from here. It is preferable to shoot a short video with your smartphone.
Start from the following HTML5 and VTT code fragments if you like:
File template.html:
<!doctype html>
<html>
<head>
<meta charset="UTF-8"/>
<title>........</title>
</head>
<body>
<h1>.........</h1>
<p>....</p>
<video id="movie1" controls preload="metadata">
<source src=".... .mp4"/>
<source src=".... .webm"/>
<track kind="subtitles" label="EN subtitles" src="....vtt" srclang="en" default/>
</video>

Introduction

Wikipedia is a great adventure. It may have
its shortcomings, but it is the largest collective
knowledge construction endevour
Disclaimer

This is just a track demo using VTT
Wednesday
Add some JavaScript to manipulate the video.
I will translate this (from our UniGE class).
Homework/project 2
Project #2 will allow you to consolidate your HTML5 video skills, i.e. work started in the classroom.
Task
(1) Create an HTML page that includes a short HTML5 video, using the video, source and track elements
- The HTML page should include all elements required to understand what the video will be about and where it comes from.
- The video must include at least four captions (subtitles) defined in a VTT file
- The page must include JavaScript code to manipulate the video. You must manage at least two events.
- You can freely choose a topic and reuse prior work.
- Video container format must be either *.mp4, *.webm or *.ogv (no other formats !!)
(2) Create a report as screen cast (Alternatively write a written report of 400 to 500 words plus screen captures)
- The report should include objectives (what is it's purpose ? audience ?) of the video, a short discussion of your design and an auto-evaluation. You also can mention how you did it, problems encountered. etc. Make sure to keep down the file size.
- Max. length of the screen cast= 2 minutes. Make sure to "dive in" directly. Do not waste time on less important stuff, e.g. your personal motivations, prior experience, etc.
Submission
Upload to the World classroom (Canevas):
- A zip file for the HTML,CSS,video,JavaScript, etc. (must be functional after dezipping)
- A report as screen cast file or written report.
Tip: Unzip the file somewhere in your own computer and test if it works (e.g. some files may be missing and the presentation will fail)
Due:
- Wednesday week 3, before class
Evaluation
- Contents: Does the HTML page together with the vido make an interesting "point" ?
- Technical elements: Correct use of tracks, subtitles and JavaScript (code works)
- Original work.
- Quality of the visual design: Is the page visually appealing ?
- Report: Does the report state the objectives, shortly present the design, include an auto-evaluation
- In time: Was the project turned in before wed, week 3, 9h ?
Resources
Introductions to HTML5 video
- HTML for Masterminds, Chapter 6
- HTML5 audio and video (Instructor's lecture notes, this wiki)
