Support writing is already scripted. The missing piece is a face, and a face is what makes a user choose a video over a paragraph. That is the whole case for avatar clips in a help centre: the copy exists, the presenter does not.
A support clip is not marketing. It should be plain, specific, and short:
One credit per second, so a forty second answer is 40 credits, about $0.45 at the Starter pack rate. A single portrait can carry every clip in the help centre, which means the marginal cost of a new answer is the script and the credits, not a recording session.
Pick the ticket that repeats most. Write the answer as 60 spoken words, create the clip, and place it above the existing article. If the written answer was clear, the clip will be clear; if it was not, the clip will show you exactly where the copy fails.
No. Convert the five to ten questions that generate the most repeat tickets, or the ones where users fail because they skip the written steps.
Thirty to sixty seconds for one question. If the answer needs longer, it is usually two questions that should be split.
Regenerate the clip from the updated script. The face and voice stay the same, so the help centre does not develop a patchwork of presenters.
A forty second answer costs 40 credits, about $0.45 at the Starter pack rate. Failed generations return the credits automatically.
