Do I need FFmpeg installed to use this skill?

Yes, FFmpeg must be installed on your system and accessible via your PATH for the script to execute the video encoding commands.

How does it handle Arabic and Hebrew subtitles?

The skill includes an intelligent auto-detection feature that identifies RTL characters and wraps them in Unicode directional marks to prevent punctuation and alignment errors common in FFmpeg.

Does this skill work for translating subtitles?

While this skill handles the embedding process, it can be combined with Claude's natural language abilities to translate an existing SRT file before burning it into the video.

Can I preview the subtitles before rendering the whole video?

Yes, you can use the --extract-frame option to generate a single image at a specific second, allowing you to verify the font size and position quickly.
