Remotion Video Generator

#!/usr/bin/env python3 """ Theme Switching Demonstration ============================== Demonstrates how the tokenized design system allows seamless theme switching. Shows the same components rendered with different themes to highlight the power of design tokens. This example creates a video that: 1. Shows the same chart/code/overlay components 2. Switches between different themes (Tech, Finance, Education, etc.) 3. Demonstrates how all tokens (colors, typography, motion) change together Usage: python examples/theme_switching_demo.py """ import asyncio from chuk_motion.themes.youtube_themes import YOUTUBE_THEMES async def create_theme_comparison(): """Create a video comparing different themes.""" print("=" * 80) print("THEME SWITCHING DEMONSTRATION") print("=" * 80) print() # List available themes print("Available themes:") for theme_name in YOUTUBE_THEMES.themes.keys(): theme = YOUTUBE_THEMES.themes[theme_name] print(f" • {theme.name}: {theme.description}") print(f" Primary: {theme.colors.primary[0]}, Accent: {theme.colors.accent[0]}") print() # Create compositions for each theme themes_to_demo = ["tech", "finance", "education", "lifestyle", "gaming"] print("Creating theme comparison video...") print() # Common data for consistent comparison chart_data = [ {"label": "Jan", "value": 4200}, {"label": "Feb", "value": 5100}, {"label": "Mar", "value": 6300}, {"label": "Apr", "value": 5800}, {"label": "May", "value": 7200}, ] code_sample = """function calculateMetrics(data) { const total = data.reduce((sum, item) => sum + item.value, 0 ); return { total, average: total / data.length, max: Math.max(...data.map(d => d.value)) }; }""" # Track configuration for all themes all_tracks = [] start_time = 0 scene_duration = 6 # seconds per theme for theme_name in themes_to_demo: theme = YOUTUBE_THEMES.themes[theme_name] print(f"\nCreating scene for {theme.name} theme...") print(f" Colors: {theme.colors.primary[0]} / {theme.colors.accent[0]}") print(f" Spring: {theme.motion.default_spring}") print(f" Typography: {theme.typography.primary_font.name}") # Create a track for this theme showing multiple components theme_tracks = [ # Title card { "type": "text_overlay", "text": f"{theme.name} Theme", "position": "top", "start_time": start_time, "duration": scene_duration, "animation": "fade_in", }, # Subtitle { "type": "text_overlay", "text": theme.description, "position": "center", "start_time": start_time + 0.3, "duration": scene_duration - 0.3, "animation": "slide_up", "style": { "fontSize": "32px", "opacity": 0.8, } }, # Bar chart with theme colors { "type": "bar_chart", "data": chart_data, "title": "Monthly Performance", "start_time": start_time + 1.0, "duration": scene_duration - 1.0, }, # Code block with theme styling { "type": "code_block", "code": code_sample, "language": "javascript", "title": "metrics.js", "variant": "editor", "start_time": start_time + 2.5, "duration": scene_duration - 2.5, "position": {"x": "center", "y": "bottom"}, }, # Lower third overlay { "type": "lower_third", "name": f"{theme.name} Design System", "title": "Powered by Design Tokens", "start_time": start_time + 4.0, "duration": scene_duration - 4.0, }, ] all_tracks.extend(theme_tracks) start_time += scene_duration # Create the final composition total_duration = len(themes_to_demo) * scene_duration print(f"\nGenerating video:") print(f" Duration: {total_duration} seconds") print(f" Themes: {len(themes_to_demo)}") print(f" Components per theme: 5") print(f" Total tracks: {len(all_tracks)}") # Configuration config = { "composition_name": "ThemeSwitchingDemo", "width": 1920, "height": 1080, "fps": 30, "duration_frames": int(total_duration * 30), "theme": "tech", # Start with tech theme "tracks": all_tracks, } print(f"\nConfiguration:") print(f" Resolution: {config['width']}x{config['height']}") print(f" FPS: {config['fps']}") print(f" Total frames: {config['duration_frames']}") return config async def demo_token_usage(): """Demonstrate how to access and use tokens programmatically.""" print("\n" + "=" * 80) print("TOKEN USAGE EXAMPLES") print("=" * 80) print() print("1.
