Superseded: the video kit now does this with the captions-layer part, version 1.1.0, in the parts folder of this repository. It burns the same plate captions from the speech timings, holds the last caption to the end, transcribes only when there are no timings, and returns a WebVTT of what it drew. This atom stays, unchanged in behaviour, for skills outside the kit until they move; its scripts still run.

caption-burn

Captions timed to what is actually said in the finished video, not to the script's estimate.

Run

python transcribe.py --media reel.mp4 --out reel.words.json          # paid, cents
python captions.py --video reel.mp4 --beats cutlist.aligned.json \
    --words reel.words.json --out final.mp4 [--style plate|outline] [--highlight Brand]

--beats supplies the lines (vo), their timing and, for split layouts, seam, size and each beat's state. Any file with beats: [{start, end, vo}] works.
