ffmpeg-animation-timing-reference

To calculate FFmpeg fade and zoompan timing, convert seconds to frames using your video frame rate. This reference provides duration parameters and frame rate conversion tables to achieve exact animation durations.

ASS subtitle timing differentiates centiseconds for karaoke tags from milliseconds for animation tags. This distinction prevents timing errors when applying karaoke effects or transition animations.

Karaoke tag timing in ASS subtitles operates using centiseconds, where tags represent specific durations. This reference provides conversion tables to clarify these time units for accurate subtitle synchronization.

Optimal subtitle duration guidelines rely on caption readability formulas and psychology-based timing recommendations. This reference provides these formulas alongside platform-specific timing profiles to maximize readability.

FFmpeg supports platform-specific timing profiles and audio-video sync tolerances. This reference offers timing profiles to ensure animations and subtitles meet specific platform duration requirements.

FFmpeg drawtext animations desync when time units mismatch the video frame rate. This reference addresses frame rate considerations and expression variables to maintain precise animation timing.
