Burned-in landscape subtitles on two smoked-glass line plates, each word lighting as it is spoken with an accent trail behind the voice

What you can change · 8 settings

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.

  • Cues *
    cues · array

    The subtitle cues in order of appearance. Each one replaces the last with a single dark frame between them, which is how broadcast subtitles cut and why they are readable at speed.

    now: 3 items

  • Anchor
    anchor · "lower" | "upper"

    Which edge the block is pinned to. Lower is where every viewer expects a subtitle; move it up when your own lower third, a chapter rail or a platform bug is already down there.

    now: lower

  • Inset
    inset · number

    Distance from that edge as a fraction of frame height. The default clears the player's scrubber and its own caption row.

    now: 0.12

  • Measure
    measure · number

    Longest a line may run, as a fraction of frame width. This is what decides where cues break; wider gives you fewer, longer lines. Above about 0.7 the eye has to track too far to find the next line.

    now: 0.54

  • Plate
    plate · number

    Opacity of the pane behind the type. 0.86 keeps white type above 11:1 contrast even over a blown-out sky; below about 0.6 you are trusting the footage underneath to stay dark, which over a real edit it will not.

    now: 0.86

  • Scale
    scale · number

    Size of the whole block. Push it up for footage that will be watched on a phone, where a caption sized for a television is a line nobody reads.

    now: 1

  • Ground
    ground · boolean

    Paint a stand-in shot behind the caption, a blown-out window on one side and a dark interior on the other, which is the case the pane is built for. Off by default: this is an overlay, so it comes out on an alpha channel and drops straight onto your own footage.

    now: false

  • Brand
    brand · string

    Brand token id, one of the keys of BRANDS.

    now: slate

Prompt

I burn my subtitles into the video and the ones I make in my editor look terrible over a bright sky. I want proper two-line captions for a normal landscape video, sitting above the scrubber, where each word lights up as I say it and the words I have already said stay readable instead of disappearing. Word timings come from my transcript. It has to survive a cut from an exterior to a dark room without me regrading it, and it has to come out with an alpha channel so I can drop it over my own footage.
