<direction>
An 8-second lower-thirds showcase for A. SPEAKER, Founder, Sample Co. The frame holds a plain presenter placeholder built from shapes (head circle, shoulder arc, labelled as a placeholder). Three lower-third styles present the same name in turn: 1) a full-width light bar sliding in from the left, 2) a dark block with an accent edge, 3) a minimal accent line over one line of type. Near-black frame, one orange accent.
Banned: fake photos of people, glows, gradients, animated sparkles, swoosh sounds implied by swoosh shapes.
</direction>
<structure>
Each style holds ~2.6s: Beat in — the lower third enters (slide / rise / draw, per style). Beat hold — fully readable, nothing moves. Beat out — it leaves the way it came, 12 frames. A progress dash under the frame tracks which style is showing.
</structure>
<build>
One Remotion composition, 1280x720 landscape, 30fps. Style index = floor(frame / 78); each style is its own component keyed by the same name/role data. Entrances use spring() or interpolate() as the style demands; exits are interpolate() over the segment's last 12 frames.
</build>
<gotchas>
Lower thirds live in the bottom quarter — keep them clear of the placeholder's label and the progress dashes. Style 3's line draws by width interpolation; if the name is long, cap the line at 300px or it outruns the text.
</gotchas>
Before you finish: step through the timeline at five points and fix anything that overlaps, clips the frame, or drifts off the beat grid.
Three lower-third styles for the same speaker, shown over a shapes-only presenter placeholder — no fake person, no stock footage. Pick a style, keep the other two in your pocket.

What broke (and the fix)
- Nothing broke. Style 2 is the one in the still; all three styles enter, hold and exit on their segment beats, and each stays clear of the placeholder label and the progress dashes.
