Export Settings for Reels and Shorts: Resolution, FPS and Bitrate

The short answer: one export preset for Reels, Shorts and TikTok

One preset is enough, because all four platforms want the same thing: a vertical file in a common codec. Here it is:

• Resolution: 1080x1920 (9:16)
• Frame rate: 30 fps, or 60 if you shot at 60
• Container and codec: MP4, H.264
• Video bitrate: 8-15 Mbps, VBR
• Audio: AAC, 48 kHz, 128-320 kbps stereo

Both the Instagram Help Center and YouTube's recommended upload encoding settings point to H.264, MP4 and AAC as the safe baseline. Platform rules change, so recheck them now and then.

Resolution: why 1080x1920 beats 4K for vertical video

1080x1920 beats 4K for vertical video because every platform downscales and re-encodes your upload anyway. A 2160x3840 file has four times the pixels, uploads slower, and on a phone screen the difference disappears after re-compression.

So, 4K or 1080p for Instagram Reels? 1080p. Shooting in 4K is fine, since it gives you crop room and cleaner downscaling. Just export at 1080x1920.

Aspect ratio and safe zones

Keep the frame exactly 9:16. Dropping a landscape clip into the middle of a vertical canvas fills only about a third of the height, so it looks soft no matter your bitrate. Reframe or crop to fill the screen.

App buttons cover the top and bottom of the frame. As a working rule, not an official measurement, keep captions and faces out of roughly the top 250 px and bottom 400 px of the 1920.

Frame rate: 30 fps or 60 fps?

30 fps is the right default, and 60 fps only makes sense when you shot at 60. The real rule is to match the source and avoid conversion.

Converting 24 to 30, or 30 to 60, makes the encoder duplicate or blend frames. You get judder, not smoothness. If the footage is 24 fps, export at 24. If it's fast sports or gameplay shot at 60, keep 60 and stay near the top of the bitrate range, because 60 fps needs more data.

Codec and bitrate: what to pick and why

Use H.264 in an MP4 with AAC audio, and aim for 8-15 Mbps VBR at 1080x1920. HEVC (H.265) makes smaller files, but compatibility is patchier across apps, and you gain nothing visible once the platform re-encodes it.

What bitrate should you export for Instagram Reels? Target around 10-12 Mbps with a 15 Mbps maximum. Below roughly 6 Mbps, fast motion and gradients start to block up. Above 15 you mostly make a bigger file. That range is our guidance, not a platform figure. YouTube's help page lists around 8 Mbps for 1080p at standard frame rates.

For audio, AAC at 48 kHz and 128-320 kbps is plenty.

Bitrate by platform: Reels, Shorts, TikTok

The numbers are the same everywhere, and that's the point.

If you run several pages, export once and upload that same file everywhere. Re-exporting per platform only adds variables and chances to degrade the picture.

File size and duration limits to check before upload

Check each app's current limits before you upload, because size and length caps have changed repeatedly and will again. Don't trust a number from a blog post, this one included.

You can estimate size yourself. At 12 Mbps, 30 seconds comes to roughly 45 MB, and 60 seconds to roughly 90 MB, plus a little for audio. Short clips stay comfortably within what the apps accept.

On duration, recent Reels and Shorts limits have reached up to 3 minutes, but confirm in the help center. Shorter clips usually hold viewers better anyway, and a lean file uploads faster on mobile data.

The mistake that ruins quality: re-exporting compressed files

Re-exporting an already compressed file is the most avoidable cause of soft, blocky video. Each encode throws away detail the next one can't recover. That's generation loss.

The usual culprits are a screen recording of your own edit, a copy sent through WhatsApp or Telegram (chat apps compress hard), or a clip downloaded back from a platform. We've watched creators spend an evening testing export presets when the real problem was that they edited a chat-app copy.

One more thing. Only re-edit footage you own or have permission to use. Pulling other people's posted videos is a rights problem before it's a quality problem.

How to keep a clean master file

Keep the original camera files and the project, export your master once with the preset above, and upload that exact file to every platform. If you need a fix, go back to the project, never the export.

The same goes for tools that render for you. WowReveal produces a 9:16 vertical video from a link or upload, so the settings are mostly handled. Keep that rendered file as your master and upload it directly, not through a screen recording or a chat copy.

Quick pre-upload checklist

Thirty seconds of checking prevents most upload quality complaints. Run through this:

1. Resolution is 1080x1920, 9:16.
2. Frame rate matches the source (30 by default).
3. MP4, H.264, AAC audio.
4. Bitrate sits in the 8-15 Mbps range, and file size looks sensible.
5. Duration is inside the platform's current limit.
6. The file comes from your master, not a download, screen recording or chat copy.
7. Captions and faces sit inside the safe zones.

Mapping it to common editors: in Premiere Pro, pick the H.264 preset, set VBR with a 12 Mbps target and 15 Mbps maximum. In CapCut, choose 1080p, 30 fps and the higher bitrate option. In VN, choose 1080p, the source frame rate and the highest quality setting. Menu names shift between app versions, but the values stay the same.
