Synthesizable in Remotion · key components of the founder-tech-launch-fast-cut template.

DynamicTextHighlight

Key phrases or numbers appear on screen, often in a contrasting color, and animate with a quick scale-up or slide-in effect to emphasize spoken words.

+ Code construction recipe

Use <Text> components with `spring()` for scale and `interpolate()` for position/opacity. Employ `Sequence` to time text reveals with spoken dialogue. Utilize `AbsoluteFill` for overlay positioning.

ScreenOverlayTransition

Digital interfaces (phone, Slack, code editor) are overlaid onto live-action footage, often with a slight zoom or pan, simulating real-world interaction.

+ Code construction recipe

Implement `AbsoluteFill` for screen content. Use `Img` for static screen captures or `Video` for animated UI. Apply `spring()` for position and scale transitions, and `interpolate()` for opacity to create a smooth pop-in/pop-out effect. Consider `Blur` or `Opacity` on background video for focus.

FounderInterviewCut

Rapid cuts between individual founders and a two-shot, often accompanied by animated text identifying their roles or key statements.

+ Code construction recipe

Utilize `Sequence` for precise timing of video clips. Employ `AbsoluteFill` for full-screen video. Use `Text` components with `spring()` for position and opacity for name/title reveals, ensuring they are legible against the video background.
