We should do a social event quarterly or every semester or so, so we get to know one another better and what expertise we all have.
Video on the Web
Probably the people from Arizona Public Media are the best people to talk about this.
History of video on the web
There was none in the beginning. Not enough bandwidth.
End of 90s -- big surge of bandwidth, so video began to be feasible.
Now -- it's a part of everyday life.
There was no standard -- Shockwave, RealPlayer, QuickTime
Macromedia combined Flash and Shockwave. Flash Video won in terms of speed and file size and ubiquity.
This is where we are today for the most part.
Two big codecs - FLV/F4V and h.264.
H.264 is a revolutionary codec delivered as an MPEG4 or a MOV, usually MPEG4.
Difference between codec and container:
Codec: compressor / decompressor. Responsible for handling compression and instructions for decompression.
Container: Delivers the video that's been processed by the codec to the player. MOV, MPEG4 are examples of containers.
Progressive download: buffers first, can't jump ahead in video, easy (just point the Flash Player at the file), http://
Streaming: all live, can move to any point in the file, harder (requires streaming server like Flash Media Server), rtsp://
Popular Flash player: Flowplayer (flowplayer.org)
Not very customizable
More obnoxious if you don't have a license
Popular Flash player: jw longtail (longtailvideo.com)
Skinnable (with XML)
HTML5 brings the <video> element.
Also this book: HTML5 for Web Designers (Jeremy Keith)
MPEG4, Ogg, and WebM are supported formats (depends on the browser). MPEG4 will be supported by all except Firefox and is the best option out there.
Example: <video src="video.mp4" width="200" height="150" controls></video>
You can optionally include <source> elements within the <video> element to specify alternative containers.
You can also embed an object element for those browsers that need Flash.
JW Player will do HTML5 and Flash support.
JW Player is a great place to start. They have a free version with an unobtrusive watermark
Documentation is very good. (Longtailvideo.com/support)
Q: Can we see the other JW Player skins?
A: [showed demos on longtailvideo.com]
JWPlayer is used on UANews.org.
Q: For YouTube, do I need to include anything in m head tag? And is there any analytics capability?
A: No and no.
Q: Can a YouTube video player be prevented from linking out to YouTube?
For transcoding, Squeeze is excellent. Final Cut does this too.
Q: Is there anyone on campus who's good with Adobe Premiere (CS4 and CS5)?
A: We don't know. Online training? Lynda.com is excellent ($25/month). AzPM, OSCR?
Q: Off-topic: Does anyone have experience with distance learning software? Captivate 5?
A: Not here.
