Module structure

11. IN-CLOUD project
Interviews and showcases
 Give evidence of the use of cloud computing
Training session
 Didactic units technical production
Languages:
 English, German, Italian, Spanish, Portuguese and Greek
 Partners of the project

12. How to record them?
 Screencasts for both interviews and didactic
units
 It offers educators a quick and easy way to
produce 'show and tell' style video — great for
explaining and illustrating a range of subjects

13. Requirements:
 Proposed editing software: Camtasia
 Pros:
 Easy to use
 3 channels: screencast + webcam face recording + audio from mic
 Cons:
 Paid licence (but not expensive)
Screencast video
lectures
Powerpoint-based
video lectures
Skype-based
interviews
Laptop-based
interviews
Used for:

14. Requirements:
 Proposed editing software: Camtasia (30 days free trial)
 Other free options but with less features:
 No screencast and webcam at the same time
 No video editing
Educational licence

15. Proposed models for
interviews

16. 1. One-shot video interview with interviewer
Proposed models for interviews
Technology involved:
 Camera
 Microphone
Features:
 Easiest way

17. 2. One-shot video interview without interviewer
Proposed models for interviews
Technology involved:
 Camera
 Microphone
 Camtasia to include questions with black
background before answers
Features:
 No interviewer. Questions using text
 Allows cutting and editing: More preparation of answers
Future?
New trends?

18. Technology involved:
 Camera
 Microphone
 Camtasia
Features:
 Interviewer appears partially
 Requires 2 takes: expert (answers)+ interviewer (questions) or questions
added by text with black screen
 Allows cutting the interview
3. Two-takes video interview with interviewer
Proposed models for interviews

19. Technology involved:
 PC or smartphone for expert
 Camtasia for screencasting
Features:
 No need of microphone or camera
 No need of being physically together
 Allows cutting the interview
4. Skype video interview
Proposed models for interviews

20. Recommended model: the easiest
• Device: Laptop
• Microphone: USB mic (Snow Ball)
• Software: Camtasia (Screencast)
• Device: Laptop
• Software: Camtasia (Screencast)
or
TIP: Use the same things than in the video-lecture production process

21. Proposed models for video
lectures

22. 1. Powerpoint-based video-lectures
Technology involved:
 Camtasia
 Microphone
Features:
 Good for theory

23. 2. Screencast video-lectures
Technology involved:
 Camtasia
 Microphone
Features:
 Good for practice: show how to code, config a tool,
navigate through web sites, etc.

24. Our method
1. Write a very good sript using close language
2. Screencast video and audio following the script
3. Cut beginning and end of screencast so that it starts and ends
where you want (Optional)
4. Add beginning and end screen with name and title
(just in case it’s not a powepoint-based video-lecture)

25. Guidelines for Screencast
video lectures

26. Step 1. Clean up your desktop
Icons, applications, background, etc. Avoid possible distractions!

27. Step 2. Write a script to ensure…
 Your video includes everything you want
 Your language is exact and concise

28. Step 3. Do a practice run
 If you are using any tool or web site, practice first so
you don’t get unexpected results
 Don’t hesitate. Do it right or record it again

29. Step 4. Record the best audio possible
Use an USB microphone:
…and…

30. Step 5. Include yourself in the video
 But not all the time! It gets boring.
 Suggestion: only at beginning and end
