CRITICAL GUIDELINES

Windows File Path Requirements

MANDATORY: Always Use Backslashes on Windows for File Paths

When using Edit or Write tools on Windows, you MUST use backslashes (\) in file paths, NOT forward slashes (/).

Documentation Guidelines

NEVER create new documentation files unless explicitly requested by the user.

Viral Video Hook Templates (2025-2026)

The Science of Hooks

The Critical Window: You have 1.3-3 seconds to stop the scroll. Research shows:

• 65% of viewers decide to watch or skip within 3 seconds
• Videos with strong hooks have 2-3x higher completion rates
• The hook accounts for up to 80% of a video's viral potential

Hook Timing Reference

Optimal Hook Durations by Type

FFmpeg Time Units Quick Reference

All FFmpeg filter expressions use SECONDS with decimals:

Recommended Hook Timing

# Hook window timing breakdown:
# 0.0-0.3s: Visual impact (flash, zoom, color)
# 0.3-1.5s: Primary hook text appears
# 1.0-2.5s: Secondary text/elaboration
# 2.5-3.0s: Transition to main content

# Example: Complete hook with timed elements
ffmpeg -i input.mp4 \
  -vf "

The 10 Proven Hook Templates

1. The Pattern Interrupt

Psychology: Breaks viewer's passive scrolling state with unexpected visual/audio

Best For: All content types, especially saturated niches

FFmpeg Implementation:

# Flash/brightness pulse at start (0.5 seconds)
ffmpeg -i input.mp4 \
  -vf "eq=brightness='0.3*between(t,0,0.1)+0.2*between(t,0.1,0.2)+0.1*between(t,0.2,0.3)'" \
  -c:v libx264 -preset fast -crf 23 \
  -c:a copy \
  output_pattern_interrupt.mp4

# Zoom punch effect - 1.5x to 1.0x zoom over 0.5s at 60fps for maximum impact
# 50% initial zoom (1.5x) is highly visible on mobile, completes within 0.5s attention window
# Note: d=1 ensures continuous per-frame processing; the time conditional limits zoom to first 0.5s
ffmpeg -i input.mp4 \
  -vf "fps=60,zoompan=z='if(lt(t,0.5),1.5-t,1)':d=1:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)':s=1080x1920" \
  -c:v libx264 -preset fast -crf 23 \
  -c:a copy \
  output_zoom_punch.mp4

# Glitch effect burst (first 0.5s)
ffmpeg -i input.mp4 \
  -vf "rgbashift=rh=-5:rv=5:gh=3:gv=-3:bh=-2:bv=2:enable='lt(t,0.5)',chromashift=cbh=3:cbv=3:crh=-3:crv=-3:enable='lt(t,0.5)'" \
  -c:v libx264 -preset fast -crf 23 \
  -c:a copy \
  output_glitch_hook.mp4

Text Overlay Example:

# "STOP." appearing suddenly
ffmpeg -i input.mp4 \
  -vf "drawtext=text='STOP.':fontsize=120:fontcolor=red:borderw=5:bordercolor=white:x=(w-tw)/2:y=(h-th)/2:enable='between(t,0,1.5)'" \

Hook Performance Metrics

Platform-Specific Hook Recommendations

Optimal Animation Parameter Reference (2025-2026)

Based on viewer psychology research and platform algorithm analysis:

Zoom Parameters for Maximum Impact

Science: 50% initial zoom (1.5x) is minimum perceptible motion on mobile screens. Less than 40% zoom appears static in first 0.5s.

Pan & Tilt Parameters for Maximum Impact

Best practices:

• Pan/tilt speed: 25-50% of frame width per second for "fast" motion
• Slower than 10%/sec appears static on mobile
• Faster than 80%/sec causes motion blur/disorientation

Flash/Brightness Parameters

Warning: Avoid >10% brightness change for >0.5s (eye strain). Flashing >3Hz can trigger photosensitivity.

Shake/Tremor Parameters

Speed Ramping Parameters

Formula Reference

# 1.5x zoom over 0.5s at 60fps (optimal hook):
# Always use d=1 for continuous processing; time conditional limits effect duration
fps=60,zoompan=z='if(lt(t,0.5),1.5-t,1)':d=1:s=1080x1920

# 10% pan over 0.4s (attention-grabbing movement):
crop=ih*9/16:ih:'(iw-ih*9/16)/2 + (iw*0.1)*min(t/0.4,1)':0

# 30% brightness flash for 0.3s:
eq=brightness='0.3*between(t,0,0.3)'

# 8% zoom pulse at ~2Hz (sin(t*12) = 12 rad/s = 1.91 Hz):
fps=60,zoompan=z='if(lt(t,1.5),1+0.08*sin(t*12),1)':d=1:s=1080x1920

# 10px shake at 30Hz for 0.4s:
crop=1060:1900:(10+10*sin(t*30)):(10+10*cos(t*25)):enable='lt(t,0.4)',scale=1080:1920

# Slow-mo 1x to 0.3x over 0.8s:

Color Grading for Viral Hooks (2025-2026)

Research-Backed Color Psychology

Hook-Specific Color Grading

Pattern Interrupt - Color Flash

# Red flash in first 0.3s (danger/urgency response)
ffmpeg -i input.mp4 \
  -vf "colorbalance=rs=0.5:gs=-0.3:bs=-0.3:enable='lt(t,0.3)'" \
  -c:v libx264 -preset medium -crf 22 \
  output_red_flash.mp4

# Saturation burst (grab attention)
ffmpeg -i input.mp4 \
  -vf "eq=saturation='if(lt(t,0.4),1+0.8*t/0.4,1.8)':enable='lt(t,2)'" \
  -c:v libx264 -preset medium -crf 22 \
  output_saturation_burst.mp4

Viral-Optimized Color Grade (Complete)

# Full viral color treatment - punchy, saturated, mobile-optimized
ffmpeg -i input.mp4 \
  -vf "\
    eq=saturation=1.2:contrast=1.18:brightness=-0.01:gamma=1.05,\
    colorbalance=rs=0.08:bs=-0.06,\

    unsharp=5:5:0.7\
  " \
  -c:v libx264 -preset medium -crf 22 \
  output_viral_grade.mp4

Parameters explained:

• saturation=1.2: 20% boost for mobile screens
• contrast=1.18: Punchier blacks/whites
• brightness=-0.01: Slight crush (prevents washed-out look)
• gamma=1.05: Lift midtones slightly
• colorbalance: Warm shift (red/yellow more engaging than blue)
• curves: S-curve for film-like contrast
• unsharp: Sharpen for mobile clarity

Audio Hook Parameters (2025-2026)
