ffmpeg-animation-timing-reference

What problem does it solve?

This Skill clarifies the often confusing and inconsistent time units used in FFmpeg filters and ASS/SSA subtitle animations, preventing errors and ensuring precise control over visual timing.

Core Features & Use Cases

• FFmpeg Time Units: Understand seconds, frames, and expression variables for filters like fade, zoompan, and drawtext.
• ASS/SSA Time Units: Differentiate between centiseconds (karaoke) and milliseconds (animation tags) for accurate subtitle timing.
• Use Case: You need to create a smooth zoom effect in FFmpeg that lasts exactly 1.5 seconds. This Skill provides the exact duration parameter and frame rate conversion needed to achieve this. Or, you're timing karaoke subtitles and need to know how many centiseconds {\k150} represents.

Quick Start

Explain the difference between centiseconds and milliseconds for ASS subtitle timing.
