About this video

The build check reads the whole project as you work and says, before you press Export, what would stop it - no End Card, a file too big for a network - and what a viewer would notice, like an empty image or a character your font lacks. This tutorial takes an ad with four problems to green, one fix at a time.

Playable Ads Maker - build playable ads and end cards, export to 13 ad networks.

Transcript

Two things stop this ad from exporting - and the editor tells you before you ever press Export. The build check reads the whole project, and says what to fix.

In the next few minutes: where it lives, what blocks an export and what is only worth a look, and fixing each one.

It's the round icon beside Export. Red means something blocks the export; amber, something worth a look; green, all clear. The number is how many.

Open it. Fix these before exporting: this ad has no End Card - the page that holds the click to the store. And File size: over two and a half megabytes, when Facebook allows two.

Add New Object, Final CTA scene. An End Card is added, and that error is gone. The End Card video shows how to design it.

The size problem has its own button: Compress one asset. The background comes down by three quarters, and the ad fits every network.

Worth a look never blocks an export - but each one is something a viewer would notice. An image with no picture: choose one, or delete it.

And a missing character: this font has no arrow, so every phone would draw it in a different font. Replace it - an exclamation mark reads just as well.

The icon turns green. Open it: every network fits, and there is nothing left to fix.

Three mistakes to avoid. One: waiting for Export to find the problems. The check updates as you work - glance at it after every change.

Two: ignoring Worth a look. It won't stop the export, but a viewer will see every one.

Three: fixing a size error by deleting pictures. Compress first - it usually saves more than half.

That's the build check. See you in the next video!
