Seedance 2.0 Sizzle Reel Tutorial

Build a cinematic sizzle reel that showcases AI video generation capabilities — from raw Seedance 2.0 clips to a polished Remotion composition with animated text overlays, transitions, and branded typography.

Final result: A 48-second showcase video with:

• Rapid-fire hook sequence over a Seedance clip
• "Meet Seedance 2.0 API" intro card
• Feature showcase with labeled clips (e-commerce, UGC, storytelling, impossible scenes)
• Animated orange Aeonik Black titles with glow effects
• Blur backgrounds for vertical clips in a 16:9 composition
• Professional end card

Prerequisites

• Bun (for package management)
• FFmpeg (for image preprocessing)
• curl + jq (for API calls)
• A varg API key with ~1800 credits ($18) for clip generation

Step-by-Step Tutorial

Step 1: Generate Source Clips

The sizzle reel is composed of 8 AI-generated video clips. Each is a single 15-second Seedance 2.0 generation — no stitching, no multi-clip editing. One prompt, one API call, one clip.

export VARG_API_KEY=varg_live_xxx
bash scripts/generate-clips.sh

This script:

1. Calls POST https://api.varg.ai/v1/video with model: "seedance-2-preview" for each clip
2. Polls GET https://api.varg.ai/v1/jobs/:id until complete
3. Downloads the result to public/clips/

Cost: ~250 credits ($2.50) per clip, ~1800 total ($18) Time: ~8-12 minutes per clip (generation + watermark removal)

Clip Types

Clip	Type	Reference	Prompt Style
Silicon Valley	text-to-video	None	Single paragraph, impossible camera move
Ronin Storm	text-to-video	None	Single paragraph, action scene
Medieval Tavern	text-to-video	None	Single paragraph, impossible camera move
Night Market	text-to-video	None	Timestamped 0:00-0:02 format
Cheetah Chase	text-to-video	None	Technical camera specs (angles, speeds)
Hyperspeed Earth	text-to-video	None	Timestamped with location changes
AG1 E-Commerce	image-to-video	Product image	@image1 reference + timestamped scenes
Planner B-Roll	image-to-video	Character image	@image1 reference + UGC style

Key insight: For image-to-video clips, the reference image is pre-processed to 9:16 using blur-extend (ffmpeg) to work around a known PiAPI aspect ratio bug where the output matches the input image dimensions.

Step 2: Understand the Composition

The video is structured in 4 parts:

Part 1: Hook (0:00-0:15)

The full Silicon Valley Seedance clip plays as background. Animated text overlays appear synced to specific timestamps (from an ASS subtitle file). Each line slams in with a spring animation — alternating white and orange (accent) text.

// SizzleReel.tsx — Hook subtitles with exact timing
const HOOK_SUBS = [
  { start: 3.0, end: 3.22, text: "You idiot!", accent: true },
  { start: 3.22, end: 3.78, text: "You activated" },
  // ... 17 lines total
];

The HookSubtitles component uses useCurrentFrame() to find which subtitle is active at the current time, then renders it with spring scale + fade animation.

Part 2: Intro (15:00-16.5s)

"Meet Seedance 2.0 API" with spring-animated scale, orange divider line, and staggered "Designed for Agents." subtitle.

Part 3: Feature Showcase (16.5s-45s)

Each clip gets an ImpactTitle overlay — orange Aeonik Black text with glow pulse. Vertical (9:16) clips use BlurBgClip which renders two <OffthreadVideo> layers:

1. Blurred + darkened background (stretched to fill 16:9)
2. Sharp foreground (contained at center)

// Blur background for 9:16 clips in a 16:9 composition
<OffthreadVideo src={src} style={{ objectFit: "cover", filter: "blur(30px) brightness(0.4)", transform: "scale(1.2)" }} />
<OffthreadVideo src={src} style={{ objectFit: "contain" }} />

Part 4: End Card (45s-48s)

"varg.ai" logo with spring entrance + pulsing "Try Seedance 2.0" CTA button.

Step 3: Preview & Iterate

bun run start

Opens Remotion Studio in your browser. You get:

• Frame-by-frame scrubbing
• Real-time preview of all animations
• Hot reload when you edit any .tsx file

This is the key advantage of Remotion over FFmpeg-only pipelines — you can see exactly how text animations look before spending time on a full render.

Step 4: Render

npx remotion render src/index.ts SizzleReel out/seedance-sizzle-reel.mp4 --concurrency=4

Renders 1440 frames at 1920x1080, 30fps. Takes ~2-3 minutes on a modern machine.

Customization

Change titles

Edit the title prop in SizzleReel.tsx:

<WideClip src={CLIPS.ronin} startFrom={fps * 3} title="YOUR TITLE HERE" />

Change hook text

Edit the HOOK_SUBS array in SizzleReel.tsx. Each entry has start/end (seconds), text, and optional accent (orange vs white).

Change colors

The orange accent color #ff6b00 is used throughout all components. Search and replace to rebrand.

Add your own clips

1. Place .mp4 files in public/clips/
2. Reference with staticFile("clips/your-clip.mp4")
3. Use <WideClip> for 16:9 or <BlurBgClip> for 9:16

Change font

Replace public/fonts/aeonik-black.otf with your font. Update the fontFace declaration in SizzleReel.tsx.

Tech Stack

• Remotion — React-based video composition
• Seedance 2.0 via varg API — AI video generation (ByteDance model via PiAPI)
• Aeonik — Typography
• FFmpeg — Image preprocessing (blur-extend for aspect ratio workaround)

Prompting Tips for Seedance 2.0

Based on extensive testing, these patterns produce the best results:

1. Timestamped scene breakdowns: 0:00-0:02: Description... gives Seedance clear temporal structure
2. "Impossible camera move" format: "Continuous single take, camera tilting, rolling, spinning, flying through..." triggers Seedance's best single-take capabilities
3. Technical camera specs: Exact angles ("banks 28 degrees"), distances ("locked 2.5 meters behind"), heights ("camera height 40cm") improve motion quality
4. @image1 character anchoring: For image-to-video, reference the character in every scene: "Strictly maintain this exact person's face throughout every shot"
5. Physical detail keywords: "glass shards", "motion blur", "volumetric god-rays", "shallow DOF" improve visual quality
6. Quality suffix: Always end with "8K, photorealistic, cinematic, no text overlays, no watermarks"
