Business & product

Every feature launch, from one template.

Storyboard a product explainer on a multi-track timeline, polish the titles in Design Studio, then bind the copy to variables so every changelog and demo video renders from the same JSON.

Use case

Explainer and demo videos that keep pace with the product

Explainer and demo videos age the moment the UI changes. Zvid turns one JSON project into a finished, hosted MP4 rendered by FFmpeg, so the walkthrough you shipped last quarter re-renders frame-for-frame with new screen recordings, new copy, and a new release number the moment you change the values.

Build the first one by hand in the browser editor: unlimited video and audio tracks for screen captures and voice-over, a context-aware inspector, split, snap and zoom. Then save that project as a reusable API template. Bind the headline, feature name and version to {{placeholders}}, and every future changelog or feature-launch video comes off the same layout with a single POST.

What you get

From first cut to recurring release

Multi-track storyboard

Lay screen recordings, callout overlays and voice-over across unlimited video and audio tracks, with split, snap and zoom on a browser timeline that faithfully previews the FFmpeg output.

Titles that animate

Design Studio builds animated feature titles and lower-thirds from 78 animation presets, 55 curated fonts and per-letter stagger, saved as re-editable, reusable layers.

Captions for every clip

12 animated caption modes rendered through ASS/libass — karaoke, highlight, typewriter and more — from imported SRT, VTT or Whisper JSON with word-level timing.

Template your changelog

Turn any project into an API template with up to 200 {{variables}}, so each release swaps the feature name, version and recording without rebuilding the video.

Callouts and reveals

Hundreds of recolorable vector shapes and icons, plus 44 named transitions usable as scene changes or per-element entrance and exit animations to reveal a feature step by step.

Ship on release day

Render.completed webhooks, HMAC-signed with retries, ping your pipeline the moment a demo finishes, returning a hosted cdn.zvid.io URL to drop into the release notes.

FAQ

Frequently asked questions

How do I keep a demo video current when the product UI changes? +

Save the project as a template and bind the changing parts to variables. Swap in a fresh screen recording, feature name and version, then re-render from the same JSON — FFmpeg produces frame-accurate, reproducible output every time.

Can I turn one explainer into a whole changelog series? +

Yes. Build one video on the timeline, template it, then render each release with its own values. Bulk render handles up to 500 items per call with one batch id and a fix-and-resubmit dashboard.

Does Zvid add voice-over narration to my demo? +

Zvid does not generate or synthesize voice-over. You upload your own narration as an audio track — with per-track volume, trim, speed and fades — and FFmpeg mixes it against your screen recordings and music.
