Flowbar Launch Video

Remotion project at flowbar-launch-video/ producing a ~28s product launch video for Social and website embed.

Quick Commands

cd flowbar-launch-video

# Preview in browser
npm run studio            # opens http://localhost:3000

# Render high-quality (social)
npx remotion render FlowbarLaunchVideo out/flowbar-launch-hq.mp4 --codec h264 --crf 18

# Compress for web (faststart for streaming)
ffmpeg -i out/flowbar-launch-hq.mp4 -c:v libx264 -crf 28 -preset slow -c:a aac -b:a 128k -movflags +faststart out/flowbar-launch-web.mp4 -y

Video Structure & Timing

Duration is calculated in Root.tsx: (5 + 6 + 16 + 5) * 30fps - 45 (transitions) - 60 (trim) = 855 frames ≈ 28.5s

Act	Scene	Duration	Content
1	ProblemScene	5s	Two text cards over nature bg. Word-by-word reveals.
2	RevealScene	6s	the-reveal.mp4 + "Meet Flowbar." at bottom + tagline
3	FeatureTourScene	16s	product-tour.mp4 continuous + 5 labels at top
4	ClosingScene	5s	Logo + wordmark + description + URL

Transitions between acts use scaleBlur() with springTiming({ damping: 18, stiffness: 120 }).

Design System

Colors (from theme.ts, matches flowbar.tushar.ai)

• Background: #0c0f0d
• Text: #ede9df
• Muted: #9a9488
• Accent: #c99b6d / #ddb88a

Spring Presets (from theme.ts)

• SPRINGS.smooth — { damping: 200 } — text reveals, subtle entrances
• SPRINGS.snappy — { damping: 20, stiffness: 200 } — UI elements
• SPRINGS.heavy — { damping: 15, stiffness: 80, mass: 2 } — hero moments, logo
• SPRINGS.bouncy — { damping: 12 } — playful accents

Text Components (from AnimatedText.tsx)

• WordReveal — word-by-word stagger with clip-path mask. Use for impactful lines.
• MaskReveal — single line clip-path reveal. Use for labels, descriptions.
• ScaleReveal — scale + blur-to-sharp. Use for hero text ("Meet Flowbar.").

Layers (bottom to top)

1. THEME.bg solid color
2. AmbientBackground — nature-loop.mp4 + gradient overlay (darken prop: 0-1)
3. Scene content (TransitionSeries)
4. FilmGrain — 0.035 opacity, shifts per frame

Key Learnings & Gotchas

Motion Design

• No fades. Use scaleBlur transition or spring-based entrances. Fades look like PowerPoint.
• Springs need real physics. { damping: 200 } is critically overdamped (no visible spring). Use the presets.
• Text: mask reveals > fade+slide. clipPath: inset() with translateY looks 10x better than opacity+translate.
• Exits should be fast. Enter with spring physics (12-18 frames), exit with quick linear (5-8 frames).
• Last label in a series: skip exit fade. Pass isLast flag to hold the final label through scene end.

Video Handling

• Use objectFit: "contain" (not "cover") to show full recording including menubar. Fill bg with THEME.bg.
• pauseWhenBuffering is not available in this Remotion version — don't use it.
• Scene duration must be >= video duration or the video gets cut off. Check with ffprobe -v error -show_entries format=duration -of csv=p=0 file.mp4.
• When video is shorter than scene, the last frame freezes — this is desired behavior.

Background

• Nature loop runs GLOBALLY behind all scenes (in FlowbarLaunchVideo.tsx, not per-scene).
• Scenes are transparent — they overlay on top.
• Closing scene adds its own rgba(12,15,13,0.7) darken layer to push the bg back for text legibility.
• Problem scene adds rgba(12,15,13,0.35) darken.

Audio

• File: public/audio.mp3. Referenced via staticFile("audio.mp3").
• Volume: fades in over 1s (0→0.5), fades out over last 2s (0.5→0).
• Generate with Gemini or Suno. Prompt: warm minimal electronic, soft analog pads, 88bpm, ~35-40s, no vocals.

Rendering

• HQ: --crf 18 → ~14MB (social media)
• Web: re-encode with ffmpeg -crf 28 -preset slow -movflags +faststart → ~3MB (website embed, instant streaming)
• Always render HQ first, then compress — don't render twice.

How to Add a New Scene

1. Create src/scenes/NewScene.tsx — export a React component using AbsoluteFill
2. Keep background transparent (the global nature bg shows through)
3. Add darken overlay if text needs legibility: <AbsoluteFill style={{ backgroundColor: "rgba(12,15,13,0.X)" }} />
4. Use WordReveal/MaskReveal/ScaleReveal for text, SPRINGS.* for animations
5. Add to FlowbarLaunchVideo.tsx as a TransitionSeries.Sequence with scaleBlur() transition
6. Update duration math in both FlowbarLaunchVideo.tsx and Root.tsx

How to Re-record a Clip

1. Use Screen Studio with: minimal padding, auto-zoom 120%, smooth cursor, dark mode, 1920x1080 30fps
2. Record just the Flowbar window (not desktop bg — we have the nature loop)
3. Export as high-quality MP4, drop in public/
4. Check duration: ffprobe -v error -show_entries format=duration -of csv=p=0 public/clip.mp4
5. Update the corresponding scene's durationInFrames to match (round up to nearest second × fps)
6. Update Root.tsx duration calculation

How to Change Feature Tour Labels

Edit the LABELS array in FeatureTourScene.tsx:

const LABELS = [
  { text: "Write in markdown. Your files stay yours.", startSec: 0 },
  { text: "Todos from every note. One place to check them off.", startSec: 3.5 },
  // ...
];

startSec is relative to the feature tour scene start (not the whole video). Time them to match what's happening in product-tour.mp4.
