A subtitles clip shows every caption of a video, each at its time. A timer counts over its own length. Both take the same style as a text clip: font, size, colour, stroke, shadow and background box.

Subtitles

Each cue has a start and an end, in seconds from the clip’s start, and its text.

subtitles, every line in one clip, timed to the words

Keep captions low in the frame and clear of the buttons phone apps draw on top. On a vertical video, keep them between 13.5% and 83% of the height. See editing conventions.

From a file

Point src at an .srt or .vtt file instead of listing cues. The file sets the timing.

How each line appears

reveal sets how each cue appears. For word-by-word captions made from the speech, with no cues to write, run animated captions on the finished video.

Timers

direction sets which way a timer counts. up, the default, counts from zero. down counts from the clip’s length to zero, so a 10-second clip starts at 10.

What they can animate

Subtitles and timers take an entrance in style.animate, limited to fade and the four slides (slideUp, slideDown, slideLeft, slideRight). They reject blur, scale, a split with by, and an exit with out. Only a text clip takes an exit. Every field is in the subtitles and timer references.
