Transcript of Using audio and video - NTU version

What do we mean by Podcasting? Putting (uploading) audio & video content online is often referred to as podcasting

Specific delivery method

Syndication & subscription e.g. Real Simple Syndication (RSS)

Buzzword applied to audio and video, e.g. 'vodcasting' Creating methods Creating video Who can help? JISC Digital Media

Colleuges, technology champions, other practitioners Dedicated device Other devices Headset and recording software e.g.

Mobile phone Advantages
Little equipment required
Straight forward process
Small files for online delivery Disadvantages
no slides so visual information can be lost
lecturers face (some might consider a positive) Dedicated devices e.g. Flip Cameras Advantages
A more personalised presentation
Correct device means can be straight foward
Deliver large amount of information Disadvantages
Larger files can be more difficult for students to download
Need to get hold of the right equipment
Some software installation generally required
Can require additonal conversion Other devices:
Web Camera
Digital stills camera
Mobile phone
Video camcorder Hints and tips Set the device or software to save at lowest settings i.e. approx. 64 or even 48kbps

Use MP3 file format where possible

Use mono if available

Monitor the audio being recorded

Positioning of microphone is crucial

Save planning documents to use as alternative/ inclusive alternatives

Label recordings appropriately

Transfer audio file from device and backup

USB microphone comparisons (see left)

Headset recommendation (see left)

Bluetooth wireless headset recommendation for wire free recording(see left)

Know issues of using WMA files and other non Internet Explorer browsers

Changing audio format http://media.io/ Hints and tips Get admin access to install any software
can be immediately granted by IS

Preferred video formats .mp4, .mov or .swf

Use a tripod - any will do

Use small resolutions
e.g. WVGA (800 x 480) or smaller if possible

Keep recordings short
helps download times
50MB is getting too big Combining audio
& visuals
(slides or
screencasts) Powerpoint 2007/10 Advantages
Little equipment required
Small file sizes NOW compatible
excellent for how to demos e.g. using dropbox in NOW Disadvantages
full 'talking head' video not available
learning curve around publishing That may seem like a lot to take in...
so here's what to prioritise: 1. Try out a couple of the methods and get help if you need it

2. Preparation and planning is key

3. Aim for a specific batch of delivery

4. Practice your chosen method

5. Get feedback while your students are using the materials

6. Enhance for the next delivery Web seminaring/ lecture recording Conferencing software Key differences to 2003 version:
Allows mp3/ wma to be added directly to slides
Place and trigger bookmarks to points in your media
Use PPT to create videos
Embedding of video from external sources e.g. youtube .mov .mp4 Can use an external mic USB/
bluetooth headset + Web Camera + (optional) Advantages
Can record a whole lecture and minimise production time

Flexible tools - online office, online LT, increase access, screen capture

Usually well documented Disadvantages
Currently Windows only (although upgrade coming)
Adding to NOW requires encoding
Farily steep learning curve Marek Oledzki
