Gradient Glow Captions

Everything below can be changed without touching the animation. Hand the list to an agent, or edit the values at the bottom of the component file.

• Srt

  srt · string

  Paste an SRT or WebVTT file's text. When it has cues it replaces `words`, and each cue's time is shared across its words by length. A transcript longer than the clip plays only as far as the composition runs, so lengthen the composition to show all of it.

• Words

  words · array

  Exact per-word timings in seconds, straight from any transcription tool that exports word timestamps. Used when `srt` is empty.

  now: 21 items

• Max words

  maxWords · number

  Most words on screen at once. Three reads fastest on a phone, two feels punchier, one gives every word its own beat. A screen also ends early at a full stop or a pause.

  now: 3

• Emphasis

  emphasis · array

  Words that keep the accent colour after they are spoken instead of turning white. Matched ignoring case and punctuation, so 38412 finds 38,412. Save it for the figures and names the video is about.

  now: 2 items

• Position

  position · "lower" | "center" | "upper"

  Where the captions sit. At 9:16, lower stays above the platform's own caption and button area (the lowest 18%), and every position keeps out of the right-hand 12% where the like and share buttons are.

  now: lower

• Dim

  dim · number

  Opacity of the words not yet spoken. 0.45 lets viewers read ahead without competing with the lit word; below about 0.35 they start to vanish over bright footage.

  now: 0.45

• Glow

  glow · number

  Strength of the glow behind the spoken word. It is sized to its own word and stops short of the next one at every setting, so turning it up makes it brighter, not wider. 0 turns it off.

  now: 1

• Shadow

  shadow · number

  Dark halo under every word, which is what keeps white and dimmed words readable over a bright screen or a sky. Lower it only over footage that stays dark.

  now: 0.7

• Scale

  scale · number

  Type size relative to the frame. One size is shared by every screen of the transcript, so a long word shrinks the whole set a little rather than jumping on its own.

  now: 1

• Stage

  stage · boolean

  Draw the stand-in shot behind the captions: a desk at night lit by a monitor, with a keyboard edge and a mug, all out of focus. It is a demo backing and not part of the captions. Switch it off to put them over your own video.

  now: true

• Ground

  ground · boolean

  Paint a plain brand ground behind the captions when the stand-in is off. Off by default: with the stand-in off as well, the captions render on a transparent background and drop straight onto your footage.

  now: false

• Brand

  brand · string

  Brand token id, one of the keys of BRANDS. The gradient runs from the brand's accent to its second accent, so brands with two bright accents on a dark ground suit it best.

  now: dusk
