A grounded start beats a perfect script. Use a thirty‑second breath ladder, one sentence intention, and a smile you actually feel. Picture one real listener behind the lens. Hit record only after your shoulders drop, jaw softens, and curiosity replaces performance anxiety.
Raise the camera to eye level, keep a thumb of headroom, and align eyes on the top third. A slight forward lean signals engagement; a downward angle shrinks credibility. Test two distances, note perceived intimacy, and post your screenshots for feedback from peers.
Begin still, then let your first gesture land with your first key phrase. Match a calm inhale to your welcome line. Micro‑smile, nod once, and hold eye contact with the lens. Invite participation early by asking a concrete, answerable question out loud.
