Specifying Transient Links
The timeline
map can contain one key-value
pair for each defined transient link track. If your installation has
the standard two tracks called Overlay and
Aside, then you can add transient links by
including the keys OverlayDefault
and
AsideDefault
in the timeline
map. The actual links to be included in each track are defined in an
array, and each value in the array is a map of key-value
pairs:
{ ... "timeline":{ "cuepoints":cuepoints-value, "tracks":{ "OverlayDefault":[ { "contentID": "117", "startTime": 20.0609756097561, "endTime": 23.262195121951216, "title": "DVCPro50_NTSC_4ch_16bit.mxf" }, { "contentID": "118", "startTime": 33.87195121951219, "endTime": 39.96951219512194, "title": "DVCPro50_NTSC_4ch_16bit.mxf" } ], "AsideDefault":[ { "contentID": "114", "startTime": 5.48780487804878, "endTime": 8.536585365853657, "title": "DVCPro50_NTSC_4ch_16bit.mxf" } ] } } }
The key-value pairs are:
contentID
-
An ID for the linked content.
startTime
-
The point at which display of the link is to start, measured in seconds from the start of the original uncropped clip.
endTime
-
The point at which display of the link is to end, measured in seconds from the start of the original uncropped clip.
title
-
The title of the link.
You can add further tracks in exactly the same way:
{ ... "timeline":{ "cuepoints":tracks-value, "tracks":{ "OverlayDefault":[ { "contentID": "117", "startTime": 20.0609756097561, "endTime": 23.262195121951216, "title": "DVCPro50_NTSC_4ch_16bit.mxf" }, ], "AsideDefault":[ { "contentID": "114", "startTime": 5.48780487804878, "endTime": 8.536585365853657, "title": "DVCPro50_NTSC_4ch_16bit.mxf" } ], "ExtraTrack":[ { "contentID": "105", "startTime": 3.48780487804878, "endTime": 5.536585365853657, "title": "DVCPro60_NTSC_5ch_18bit.mxf" } ] } } }
If you want to display a transient link to an external web
site rather than to an Escenic
content item, you can do so by replacing the
contentID
key/value pair with a
url
key/value pair:
"timeline":{ "cuepoints":tracks-value, "tracks":{ "OverlayDefault":[ { "u rl": "http://www.escenic.com/", "startTime": 20.0609756097561, "endTime": 23.262195121951216, "title": "DVCPro50_NTSC_4ch_16bit.mxf" }, ] } } }
