Encoding Method Summary

Method 1
############
Use VLC to RIP DVD if needed. I had raw source on some of them
Use Quicktime to create web optimized mov file and html

Pros:
-various versions of your movie optimized for web-delivery. 
-Uses a reference movie, which selects the best version for your users' various devices and connection speeds. By including this reference movie in your HTML page, you can ensure a quality video experience on your site. (not sure if Handbrakes H.264 ourput does the same.
-Output is basically the same as iMovie, with less steps

Cons:
-Multi steps
-requires quicktime to be installed
-Files size large, however still greatly reduced compared to orginal DVD file

Method 2
############
Use Handbrake to RIP DVD and crate H.264 file based on the following write up:
http://diveintohtml5.org/video.html

Pros:
-Smaller file size, more control over resolution. 
-Should work one all browser, but have not tested. 
-native HTML5 support, Flash wrapper for old browsers 
-Handbrake supports command line and batch jobs

Cons:
-OSX firefox does not work

File size compare:
############

EPICS_Device_Support_6_25_2010_Part1  via Quicktime = 1.35GB
    @ web optimazation set for high bandwidth 

EPICS_Device_Support_6_25_2010_Part1  via handbrake = 362MB
    @24FPS 600 bitrate web optimazation

Problems:
############
EPICS Device Support with Stephanie Allison

• EPICS_DeviceSupport_6_25_2010_Part2 is missing, disk was really the same as EPICS_DeviceSupport_6_25_2010_Part1

RTEMS Programming and RTOS Concepts with Eric Norum

• Part 1 is incomplete, Video is only a 11 seconds long
• Part 2 is incomplete, Video is only a 2  seconds long 

Other

• -need to find a good home for the large files. Confluence max files size is 200MB.Depending on encoding method, files maybe 100MB to 2+GB.
