Create High-Converting Facebook Ads
Facebook Ads

Facebook feed video ads support up to 4 GB files with a maximum length of 241 minutes, though Meta recommends 15 seconds or less for best performance. Recommended resolution is 1080 x 1080 (1:1) or 1080 x 1350 (4:5). AdCreate automatically exports in the correct resolution and codec (H.264, AAC audio) so your uploads are accepted on the first try.

Yes. AdCreate exports 9:16 vertical videos at 1080 x 1920 — the exact spec Facebook Reels requires. You can use any of our AI video tools (text-to-video, avatar video, image-to-video) and select the Reels preset to get a ready-to-upload file.

Meta recommends 3-5 creative variations per ad set when using Advantage+ placements. With AdCreate you can duplicate a project, swap the hook or CTA, and export a new variation in under a minute — making it easy to produce enough variations for meaningful A/B tests.

While you can use the same creative across both platforms, dedicated assets perform better. A 1:1 video works well in Facebook Feed, but Instagram Feed favors 4:5, and both Reels placements need 9:16. AdCreate lets you resize a single project to multiple aspect ratios so you can optimize for each placement.

For awareness campaigns Meta recommends under 15 seconds, and for conversion campaigns 15-30 seconds tends to perform best. Videos over 60 seconds see a significant drop in completion rate. AdCreate's templates are pre-timed to these sweet spots so you stay within best-practice lengths automatically.
