Marketing & sales
Test every variant without a designer in the loop.
Turn one JSON template into dozens of ad-creative variants per audience. Swap headlines, offers, and product-feed rows through variables, then fire up to 500 renders in a single call and get back hosted video and image URLs.
For marketers
Creative volume without the design bottleneck
Growth teams lose weeks waiting on hand-built ad variants. With Zvid, you build one JSON template with {{placeholder}} variables — up to 200 of them, nested 8 levels deep — then POST an array of value sets. Each row becomes its own rendered video or image, so a single test matrix of headlines, hooks, offers, and colors expands into dozens of on-brand variants at once.
Bulk accepts up to 500 renders per call with best-effort per-item validation and billing: valid items queue and start rendering while any invalid rows come back in itemErrors by index, under one batch id. When a variant fails validation, fix and resubmit it from the dashboard or export the batch to CSV — so a creative refresh becomes one API call, not a design sprint.
What you get
Built for the test-and-scale loop
A/B/n at scale
One JSON template plus {{placeholder}} substitution (up to 200 type-preserving variables) expands into dozens of headline, hook, and offer variants per audience.
One video per feed row
Use iterate to expand one scene per array item with an auto index, so every product-feed row renders its own variant with auto-chaining transitions.
500 in one call
Bulk up to 500 renders per POST with per-item validation and billing — valid rows queue while invalid ones return in itemErrors by index under one batch id.
Fix and resubmit
Manage batches from the dashboard: catch invalid rows, correct them, resubmit, and export the whole batch to CSV for your reporting.
Pay per second
Video bills 1 credit per second at or below Full HD, so a wide test matrix stays predictable — you only pay for what renders.
Ping when ready
HMAC-SHA256-signed render.completed and render.failed webhooks push each hosted URL to your stack the moment a variant is done.

The features that make it work
Bulk Rendering
Fan one template out into up to 500 renders in a single call. Each item is validated and billed on its own, so one bad payload never sinks the batch.
Templates, Variables & Logic
Save a project once, render it with different data forever. Placeholders, conditional scenes, and array iteration resolve server-side before validation.
JSON Video API
Render a finished, hosted video from one authenticated POST. Send an inline JSON project or a template id and get back a job you can poll or get pinged about.
Image Rendering
Generate still images — thumbnails, banners, OG cards — from the same JSON that renders video. PNG, JPG, or WebP, with transparency, at 10 images per credit.

Frequently asked questions
How do I generate dozens of ad variants from one design? +
Build a single JSON template with {{placeholder}} variables for the headline, offer, colors, or product image, then POST an array of value sets to the bulk endpoint. Each set renders as its own hosted video or image URL, up to 500 per call.
What happens when some variants in a batch have bad data? +
Bulk uses best-effort per-item validation and billing: valid rows queue and render while invalid rows come back in itemErrors keyed by index, all under one batch id. You can fix and resubmit those rows from the dashboard or export the batch to CSV.
Can I generate one video per row of my product feed? +
Yes. Pass your feed as an array and use the iterate field to expand one scene per row with an alias and auto index, or send each row as a bulk item. Either way you get one rendered variant per product, returned as a cdn.zvid.io URL.
