Notes & best practice

Content video embedded on the Native Article landing page; it must be content, not a pre-roll ad.

Nativo's article spec asks for a raw MP4 or a YouTube embed, ideally 1 to 3 minutes; its spec table also lists MOV, WEBM and Vimeo embeds, up to 2 GB and 5 videos per page.

No resolution is published.

Notes & best practice

Standalone in-feed native video player (not pre-roll).

Scroll-to-Play autoplays muted when 50% of pixels are in view.

Click-to-Play is user-initiated with audio.

Minimum player widths: mobile preview must be at least 250 px wide, desktop must be at least 400 px wide to qualify as large-player inventory.

Upload an H.264 MP4 at 1920x1080 (1280x720 minimum) under 2 GB, or a third-party VAST tag; 15 to 30 seconds is ideal and 3 minutes is the maximum.

The unit also needs a cover image, 800x600 or larger.

8. Vertical Video (9:16)

Vertical / Portrait
9:16 2 GB MP4MOV Up to 30 seconds — Medium confidence — verified against reputable sources

Notes & best practice

Full-screen vertical video served in the feed on mobile.

It autoplays muted when the user scrolls to it; a tap turns on sound and opens an expanded view.

Nativo states only the 9:16 ratio, so 1080x1920 is a common size for that ratio, not a Nativo figure.

VAST tags are not supported yet.

Keep key content and text inside the safe zone — the platform UI overlaps the top and bottom of full-screen 9:16 creatives.

9:16 3 MB PNGJPGGIF — 1 Medium confidence — verified against reputable sources

Notes & best practice

Image slide for Nativo Stories, a full-screen mobile format that opens from a standard in-feed unit.

Each image stays on screen for 6 seconds; animated GIFs up to 6 seconds also work.

Nativo asks for a vertical 9:16 image but gives no pixel size, so 1080x1920 is a common size for that ratio.

The in-feed unit still needs its own preview image and headline.

Keep key content and text inside the safe zone — the platform UI overlaps the top and bottom of full-screen 9:16 creatives.

Notes & best practice

Video slide for Nativo Stories, the full-screen mobile format that opens from an in-feed unit; each video plays in full before the next slide.

Nativo accepts ratios from 9:16 to 16:9 and 4:5 and asks for the highest resolution that fits 2 GB; 1080x1920 is a common 9:16 size, not a Nativo figure.

Apple ProRes and YouTube links are not supported.
