Roblox Clip Transformer

Transform raw Roblox gameplay footage into platform-ready promotional content (TikTok, YouTube Shorts, Reels). Auto-edit with smart trimming, aspect ratio conversion, music sync, captions, and brand overlays. Use when creating game trailers, promotional clips, or social media content from Roblox recordings. Ideal for game developers, content creators, and marketing teams.

Transform raw Roblox gameplay into polished, platform-ready promotional clips in minutes.

What This Skill Does

Takes raw Roblox screen recordings and produces edited vertical/horizontal videos optimized for TikTok, YouTube Shorts, and Instagram Reels.

Core Capabilities:

• Aspect ratio conversion (16:9 → 9:16)
• Smart action detection and trimming
• Beat-synced transitions
• Auto-generated captions
• Brand overlay support

Quick Start

bash

# Basic usage - horizontal to vertical
roblox-transform input.mp4 --output output.mp4 --platform tiktok

# With captions
roblox-transform input.mp4 --output output.mp4 --platform shorts --captions

# Full trailer mode
roblox-transform input.mp4 --output output.mp4 --platform tiktok --trailer --title "My Game" --cta "Play Now!"

Workflow

1. Analyze Footage

The skill automatically detects:

• Action moments (movement, transitions, key events)
• Dead time (menus, loading screens)
• Audio peaks (for caption timing)

bash

python scripts/analyze-footage.py input.mp4 --output analysis.json

2. Configure Platform

Each platform has specific requirements:

Platform	Aspect Ratio	Duration	FPS
TikTok	9:16	15-60s	30
YouTube Shorts	9:16	<60s	30
Instagram Reels	9:16	15-90s	30
YouTube Horizontal	16:9	Any	30

See references/platform-specs.md for full details.

3. Generate Output

bash

python scripts/platform-render.py input.mp4 \
  --analysis analysis.json \
  --platform tiktok \
  --output final.mp4

Features

Smart Trimming

Automatically removes:

• Menu screens
• Loading screens

Aspect Ratio Conversion

Converts horizontal gameplay to vertical while:

• Centering key action
• Adding blurred background fill
• Preserving important elements

Music Sync

Beat-synchronized transitions using:

• Royalty-free tracks in assets/music/
• Custom audio with --music path/to/track.mp3

Auto Captions

Generates timed subtitles:

• Extracts audio with Whisper
• Syncs to video timeline
• Styles for readability

bash

python scripts/caption-sync.py input.mp4 --output captions.srt

Brand Overlays

Add:

• Game logo (PNG with transparency)
• Watermark
• Call-to-action text
• Title cards

Scripts Reference

Script	Purpose
analyze-footage.py	Detect action moments, remove dead time
platform-render.py	FFmpeg wrapper for platform-specific output
caption-sync.py	Whisper-based caption generation
music-sync.py	Beat detection and transition timing

Requirements

System Dependencies:

• FFmpeg (for video processing)
• Python 3.10+
• Whisper (for captions, optional)

Python Packages:

• ffmpeg-python
• librosa (for beat detection)
• openai-whisper (for captions)

Install with:

bash

pip install ffmpeg-python librosa openai-whisper

Examples

Example 1: Basic Vertical Clip

bash

roblox-transform gameplay.mp4 --output tiktok.mp4 --platform tiktok

Example 2: Vertical with Captions

bash

roblox-transform gameplay.mp4 --output shorts.mp4 --platform shorts --captions --language en

Example 3: Game Trailer Mode

bash

roblox-transform gameplay.mp4 \
  --output trailer.mp4 \
  --platform tiktok \
  --trailer \
  --title "Escape the Castle" \
  --logo assets/logo.png \
  --cta "Play Now!"

Example 4: Multi-Platform Export

bash

# Generate for all platforms
roblox-transform gameplay.mp4 --output-dir ./exports --platform all

Output Structure

text

exports/
├── tiktok_916_30fps.mp4
├── shorts_916_30fps.mp4
├── reels_916_30fps.mp4
└── youtube_169_30fps.mp4

Limitations

• Best results with gameplay 30+ seconds
• Caption accuracy depends on audio clarity
• Beat sync works best with music-heavy sections

Troubleshooting

"FFmpeg not found"

• Install FFmpeg: apt install ffmpeg or brew install ffmpeg

"Whisper failed"

• Captions optional - skip with --no-captions
• Or install: pip install openai-whisper

"Output too long"

• Use --max-duration 60 to limit length
• Smart trim will prioritize best moments

Next Steps

1. Place raw gameplay in your working directory
2. Run basic transformation: roblox-transform input.mp4 -o output.mp4 -p tiktok
3. Review output and adjust settings
4. Add brand elements for polished trailer
