What are the video specs for Facebook video ads?
For Facebook Feed, Meta's Ads Guide recommends a 4:5 MP4, MOV or GIF at 1,440 × 1,800 pixels, H.264 compression and stereo AAC audio, up to 4 GB and 241 minutes. Allowed length changes by placement: 5–15 seconds for desktop in-stream video, but up to 60 minutes on Instagram Feed and Stories.
A Facebook Feed video ad works best as a vertical 4:5 file at 1,440 × 1,800 pixels, exported as MP4 or MOV with H.264 video and stereo AAC audio. Every video ad shares a 4 GB size ceiling, but how long your video may run depends on where it shows: Feed allows hours, while in-stream and Stories placements cut off far sooner.
What does Meta recommend for a Facebook Feed video?
Meta’s Ads Guide lists these specs for video ads in Facebook Feed:
- File type: MP4, MOV or GIF
- Ratio: 4:5, at a resolution of 1,440 × 1,800 pixels
- Video settings: H.264 compression, square pixels, fixed frame rate, progressive scan, and stereo AAC audio at 128 kbps or more
- Duration: 1 second to 241 minutes
- Maximum file size: 4 GB
- Captions and sound: optional, but recommended
Meta’s troubleshooting page adds that the computer version of Facebook Feed shows video at 1:1, which can put black bars on either side, and that your video should be at least 600 pixels wide to render well.
How long can a video ad be in each placement?
Meta publishes a separate length table per placement. Shorter videos are usually more engaging on mobile, Meta notes, but these are the allowed ranges:
| Placement | Allowed length |
|---|---|
| Facebook Feed | Up to 241 minutes |
| Facebook Marketplace | Up to 241 minutes |
| Facebook in-stream video (mobile) | 5 seconds to 10 minutes |
| Facebook in-stream video (desktop) | 5 to 15 seconds |
| Facebook Stories | 1 to 120 seconds |
| Instagram Feed, Stories and Explore | Up to 60 minutes |
| WhatsApp Status | Up to 60 minutes |
| Audience Network native, banner and interstitial | 1 to 120 seconds |
| Audience Network rewarded video | 3 to 61 seconds |
What specs apply to Stories and Reels?
Meta recommends 9:16 for full-screen vertical placements. Its Instagram Stories design page lists:
- Recommended resolution 1,080 × 1,920 pixels; minimum 600 × 1,067
- MP4 or MOV, up to 4 GB
- Video codecs H.264 or VP8; audio codecs AAC or Vorbis
For 9:16 ads in Stories, Reels and Feed, Meta asks you to keep the top, bottom and side edges free of key text and logos. On screens taller than 9:16, Meta may zoom the creative to fill the screen, which can crop anything outside the safe zone.
Which video file formats can you upload?
Meta lists 30 supported video formats, including MP4, MOV, GIF, AVI, MKV, WMV and MPEG. For best results it recommends GIF, MOV or MP4.
How do you fix a video that will not upload or looks blurry?
- Check the format and switch to MP4 or MOV if needed.
- Confirm the file is under 4 GB.
- Check the length against your chosen placement’s limit.
- Re-export at a larger size if the video looks pixelated, keeping at least 600 pixels of width.
- Preview the ad in Ads Manager to confirm it renders correctly.
If uploading in Ads Manager still fails, Meta suggests uploading to the Meta Media Library instead.
FAQ
Do video ads need captions?
Meta’s Ads Guide lists both captions and sound as optional but recommended for Facebook Feed video ads. A video without captions can still be published, but Meta’s own spec sheet advises adding them. Check the Ads Guide entry for your specific placement before you export the final file.
Why are the headline and button missing from my video ad?
Meta’s troubleshooting page says that with the Awareness objective, or performance goals such as maximize reach or maximize 2-second continuous video views, the ad footer is not shown in Facebook Feed on mobile. That footer includes the headline, description, call-to-action button and website URL.
Can I use different cuts for different placements?
Yes. Meta’s video length page says you can use different video edits for different placements with asset customization for placements. That lets you run a longer cut in Feed and a shorter vertical cut in Stories or in-stream placements from the same ad.
