Liveclicker can create a transcript from a video asset. To do so, click on "Request" from the asset detail page.
A pop-up will appear, where you can confirm your request.
As soon as the transcript request is confirmed, you will receive a transcript request confirmation email to your inbox.
Finally, you need to click again on "Request" for the appropriate asset page, and click on the confirmation link (see below). This will copy the proposed transcript to your live transcript. At that point, all widgets created from this asset will have the transcript attached to them (it will also show on any of your video sites).
