Captions and fonts

Captions are burned in and generated from the voiceover's word-level timings, so they match the read exactly. Styling comes from a caption typography catalogue with real fallbacks per family, which is why a style renders the same on the render server as it does in the preview.

How styling works

  • Each caption design specifies a family, weight, size band, colour treatment and position.
  • Sizes are chosen relative to the frame, so a 9:16 export and a 1:1 export do not end up with the same absolute text size.
  • Every family declares a fallback, so a missing font renders as something deliberate rather than as a default sans.
  • Position respects the placement's safe zone rather than a fixed offset.

Editing captions

  1. Open the variation in the editor.
  2. Edit the caption text. Timing is preserved because it comes from the audio, not from the text length.
  3. Change the design if you want to test a different caption treatment.
  4. Re-export. There is no credit cost.

Frequently asked questions

Can I change the caption font?

Yes, from the caption typography catalogue, per variation. Custom brand fonts are an Enterprise conversation.

Do captions stay in sync if I edit the text?

Yes. Timings come from the voiceover audio rather than from the caption text, so shortening a line does not shift the sync.

Can I turn captions off?

Yes, per variation, which makes captions versus no captions a testable variable.
