Overview

This skill generates polished 1080×1920 short-form video ads (TikTok / Reels / Shorts) from product clips and images. It produces three built-in viral styles — Clean, Meme, and UGC — and runs locally using Python and ffmpeg so no cloud APIs or external services are required. The output is ready-to-publish H.264 video with warm color grade and mobile-optimized framing.

How this skill works

You provide a JSON config that lists scenes (video clips or images), durations, transitions, music, and a chosen style. The Python scripts stitch assets together with overlays, fonts, and transitions, encode to 1080×1920 at 30 FPS, and export H.264 + AAC. Optionally enable beat-sync (requires librosa) to snap cuts to detected beats. Fonts and basic color grading are applied automatically based on the selected style.

When to use it

• Create mobile-first product ads quickly from existing clips and photos
• Prototype multiple ad variations in different viral styles
• Produce privacy-friendly assets entirely on local machines (no cloud)
• Generate social creatives for launches, promos, or organic growth experiments

Best practices

• Prepare high-quality 9:16 clips or portrait-cropped images for best framing
• Keep hooks short and bold for Clean or Meme styles; UGC favors minimal overlay
• Provide a single music track and enable beat_sync only if you want precise cut timing
• Use the included fonts (Anton, Montserrat) or supply matching TTFs in the fonts folder
• Test outputs on a phone before publishing to confirm text size and safe areas

Example use cases

• Turn demo clips and product photos into a 15–30s TikTok ad with a bold hook overlay
• Create humorous meme-style cuts with ALL-CAPS captions for viral testing
• Produce a UGC-style vertical ad that only shows a creator username pill and feels authentic
• Batch-render several style variants for A/B testing creative performance on Reels
