Do I need separate software to use this skill?

Yes, this skill requires FFmpeg for video processing and Whisper (or a similar tool) for generating the initial word-level timestamp data.

What are CapCut-style captions?

They are dynamic, word-level animated subtitles where words often 'pop' onto the screen or change color as they are spoken to increase viewer retention.

Can I customize the fonts and colors?

Absolutely. The skill generates ASS subtitle files where you can specify Fontname, Fontsize, PrimaryColour, and animation timing parameters.

Does this support vertical 9:16 videos?

Yes, the templates and positioning logic are specifically optimized for mobile-first vertical formats used on TikTok, Reels, and Shorts.
