No, you should be ok with one license as long as your client doesn’t make other changes to the video.
" What are allowed variations of a single application?
In addition to a series, allowed variations of an end product that are still considered a single application include:
- Translations - the same end product simply translated into a different language (e.g. alternate text or alternate voiceover)
- Cut-downs - a shortened version of an end product where no new content has been added (e.g. a 15 second “teaser” version of a film trailer)
- Tag changes - minor revisions to text or content (e.g. changing “Coming Soon” to “Now Showing”) "
