Facebook Reels export settings
A good export starts with your destination. Prepare a clear vertical video, then check the upload flow you will use. Facebook's newer video experience and LoopBatch's publishing checks have different limits.

- What you will have
- A finished video with an export plan you can check.
- What you need
- Your edited video and the export settings in your editor.
- How long it takes
- About five minutes to check settings, plus export time.
Before you start
- Decide whether you will upload in Facebook itself or publish to a Page through LoopBatch.
- Keep your original footage. Re-export from the project when settings need to change.
- Review text, captions and the opening frame on a phone-sized preview.
A practical starting preset
For a short vertical Reel, start with 1080 × 1920 pixels, 9:16, at 30 frames per second. Export an MP4 with H.264 video and AAC audio; 48 kHz stereo is a useful starting point when your project has stereo audio. These are our planning recommendations and match LoopBatch's common encoding.
Match the frame rate of suitable source footage when possible. Enlarging a small clip cannot restore detail that was never captured. Reframe landscape footage deliberately so the subject stays visible; a stretch to portrait usually distorts it.
Keep essential text away from the edges and preview where Facebook places captions and buttons. Check the actual viewer layout rather than treating one set of margins as universal.
Why upload limits can look different
In June 2025, Meta announced a unified Facebook video flow in which new videos are shared as Reels, with the old length and format restrictions removed. The announcement describes a gradual rollout to profiles and Pages. Read Meta's announcement.
LoopBatch publishes to Facebook Pages through its existing Reels integration. Its current checks still require a short vertical export. A longer or landscape upload accepted in Facebook itself can therefore fail a LoopBatch check. Use the requirements of your chosen publishing path.
What LoopBatch checks before publishing
| Measurement | Product check | How it is used |
|---|---|---|
| Video length | 3 to 90 seconds | Must pass before approval |
| Frame rate | 23.9 to 60 frames a second | Must pass before approval |
| Video width | at least 540 px | Must pass before approval |
| Video height | at least 960 px | Must pass before approval |
| Video shape | 9:16, vertical | Must pass before approval |
| Video width | at least 1,080 px | Recommendation; does not block approval |
| Audio sample rate | 48 kHz | Recommendation; does not block approval |
| Audio channels | 2, stereo | Recommendation; does not block approval |
This table is drawn from LoopBatch's current product rules. It is not a claim that these limits apply to every Facebook upload flow. The linked API source retains its 14 September 2026 read date; it could not be fetched again for this guide.
The free social video checker uses the same rules. Choose Facebook Reel and enter the final file's measurements, or read them from a local video. The checker assesses measurements; it does not validate your account access, content, licence or AI disclosure.
A worked file-size estimate
Suppose you export a 30-second clip at an average video bitrate of 8 Mb/s, with audio at 128 kb/s. The combined rate is 8.128 Mb/s. Multiply by 30 seconds and divide by eight: the estimate is 30.48 MB, before small container overheads.
That is an illustration, not a Facebook bitrate requirement or an upload guarantee. Actual output depends on the encoder and how much motion and detail are in the clip. A quality-based export may vary its bitrate. Compare the real file size with the estimate and watch for blurred text, blocky motion or damaged audio.
The steps
Choose the publishing path: Facebook's own upload flow or LoopBatch's Facebook Page integration.
Set the canvas, frame rate, video codec and audio settings in your editor.
Export one finished file, then inspect its actual dimensions, duration and frame rate.
For LoopBatch, choose Facebook Reel in the free checker and resolve any blocking measurements.
Watch the full export with sound and review its disclosure before approving or uploading it.
Check the result
- The subject is visible without stretching, unwanted cropping or black borders.
- Captions are readable on a phone and do not hide behind interface controls.
- Measurements come from the final file rather than the editor's project settings alone.
- Your chosen upload path accepts the duration and shape you prepared.
If something goes wrong
- If Facebook accepts the clip but LoopBatch rejects it, compare the publishing paths. LoopBatch's current Page integration has its own checks.
- If the image looks soft, check the source resolution and compression. Increasing the export dimensions alone will not restore missing detail.
- If the filename ends in .mp4 but a codec check fails, inspect the encoding. MP4 is a container, and renaming a file does not change its video codec.
- If you hear distortion or see text breaking up, return to the original project and export again with suitable quality settings.

Common questions
Do all Facebook Reels still have a 90-second limit?
Meta announced that its unified Facebook video flow removes the old length and format restrictions. LoopBatch's current Facebook Page integration still checks a 3-to-90-second duration. Check the upload path you are actually using.
Is 1080 × 1920 a universal Facebook requirement?
It is a useful portrait preset for a short Reel and a recommendation in LoopBatch's current checks. The newer Facebook upload experience supports a wider range of video formats. Choose dimensions that suit your footage and publishing path.
Does the free checker approve my video for Facebook?
It checks measurements against LoopBatch's product rules. It does not publish the video, inspect its content or confirm that Facebook will accept it for your account.
