Short answer: worth asking about, not something to assume comes as standard. Here's the honest version.

KSA Headshots sessions are built around stills — a photographer's setup, lighting and pace for photographs, not a video production. But a stills session already has you in good light, relaxed, and moving naturally between poses. A few seconds of that captured as video is a genuinely different thing from booking a full video shoot, and it's a small, worthwhile add to discuss when you book, rather than a fixed product with its own price on the site today.
If a short clip matters to you — a LinkedIn video intro, a few seconds for a website hero, something to go with your headshots rather than replace them — mention it at booking. Whether it's workable depends on the studio, the time available in your package, and what you're trying to get out of it, so it's a conversation rather than a tick-box.
Basic, Premium or Ultimate — whichever fits your needs on packages.
Mention it when you book, or reply to your confirmation email, so it can be planned into the time rather than squeezed in.
A natural movement, a turn, a laugh — a few seconds, not a script or set list.
Your retouched images remain the main deliverable; a clip is a bonus, not a replacement for the photography.
If what you actually want is a very quick, low-cost single portrait rather than a video moment, Once a year. £50. Ten minutes. One retouched headshot.
