Alternative Source

Scope

• Book Page content object > Video object > Alternative Source 1 property
• Book Page content object > Video object > Alternative Source 2 property

Purpose

The Alternative Source 1 and Alternative Source 2 properties can be used to specify an alternative source of the video file to be played for the associated Video Book Page object. Normally, you would link to the same video in another file format - for example, if the main video file is a .wmv file, you could use these two properties to link to the same video saved in .mp4 and/or .m4v format. Then, if the primary-sourced video cannot be played back on the user's PC (maybe they are on an iPhone which [at the time of writing] doesn't natively support .wmv), one of the fallback methods will be used instead.
