Instagram Video Format: Complete Specs for Reels, Stories, and Feed

Instagram accepts video in MP4 or MOV format, using the H.264 codec and AAC audio. The right instagram video format depends on where you're posting — Reels, Stories, feed, or Live each have different aspect ratios, resolutions, and length limits.

Instagram Video Specs at a Glance

Before anything else, here's the full picture in one place.

Format	Aspect Ratio	Resolution	Max Length	File Type
Reels	9:16	1080×1920	90 seconds	MP4 / MOV
Stories	9:16	1080×1920	15 sec per clip	MP4 / MOV
Feed (Portrait)	4:5	1080×1350	60 minutes	MP4 / MOV
Feed (Square)	1:1	1080×1080	60 minutes	MP4 / MOV
Feed (Landscape)	16:9	1920×1080	60 minutes	MP4 / MOV
Live	9:16	720p minimum	Up to 4 hours	Streamed

Most creators shooting for Reels or Stories can set their camera to vertical 1080p and be done with it. Feed posts give you more flexibility, but portrait (4:5) tends to take up more screen space which generally works in your favor.

What File Format Does Instagram Accept?

Recommended Video File Format

MP4 is the standard. It's widely supported, compresses well, and exports cleanly from virtually every editing tool. MOV files are also accepted, though MP4 is the safer default if you're unsure.

What Instagram does not accept: AVI, FLV, WMV, or raw camera formats like R3D or BRAW. Export from those formats before uploading.

Codec and Audio — What's Actually Happening Under the Hood

This is where people get confused. MP4 is a container — it's the file wrapper. H.264 is a codec  the compression standard that encodes the actual video inside that container. They're related but not the same thing.

According to Wikipedia, H.264 is one of the most commonly used formats for the compression and distribution of video content across the internet.When editors say "export as H.264," they typically mean an MP4 file using H.264 compression.

That's what Instagram expects.For audio, AAC (Advanced Audio Coding) is the recommended standard. It delivers better quality than MP3 at similar file sizes, and Instagram handles it cleanly on upload.

General Technical Parameters

• Frame rate: 23–60 fps accepted; 30fps is the common standard, 60fps for smoother motion
• Maximum file size: 4GB
• Recommended video bitrate: 3,500–5,000 kbps for 1080p content
• Audio bitrate: 128 kbps minimum; 192 kbps recommended

In practice, most editors export at 30fps unless they're specifically shooting fast-moving content. Higher frame rates don't make content perform better algorithmically — they just look smoother.

Instagram Video Format by Placement Type

Instagram Reels Format

Reels is Instagram's primary video surface. It's vertical-only. As reported by TechCrunch, Instagram made Reels the default format for all new video posts under 15 minutes as part of its move to consolidate video across the platform.

• Aspect ratio: 9:16
• Resolution: 1080×1920
• Max length: 90 seconds
• Safe zone: Keep key text and visuals between roughly 250px from top and bottom edges  Instagram's UI (profile icon, caption, like/share buttons) overlays both ends of the frame

What's often overlooked is the safe zone. Creators regularly place on-screen text in areas that get covered by Instagram's native UI. If a caption or logo sits near the bottom 20% of the frame, there's a good chance viewers won't see it.

Instagram Stories Format

Stories share the same vertical dimensions as Reels but behave differently.

• Aspect ratio: 9:16
• Resolution: 1080×1920
• Max length: 15 seconds per clip (longer videos are auto-split)
• Disappear after: 24 hours unless saved to Highlights

The practical difference: Reels are discoverable by people who don't follow you. Stories are visible only to followers (unless you use the Close Friends or broadcast channel features). Same format, different reach.

Instagram Feed Video Format

Feed posts give you three aspect ratio options. Which one you choose affects how much screen space your video occupies in someone's scroll.

• Portrait (4:5): 1080×1350 — takes up the most vertical space in the feed; generally recommended for organic content
• Square (1:1): 1080×1080 — the original Instagram format, still common for brand consistency
• Landscape (16:9): 1920×1080 — takes up the least feed space; better for cinematic content where width matters
• Max length: 60 minutes (though most feed videos perform better under 60 seconds in practice)

If you upload a 16:9 video without cropping it for the feed, Instagram will letterbox it with black bars. That's not a technical error — it's just what happens when the aspect ratio doesn't match the display container.

Instagram Live Video Format

Live is streamed, not uploaded, so the technical constraints are different.

• Aspect ratio: 9:16 (vertical, like Stories)
• Minimum resolution: 720p (1280×720); 1080p recommended where your device and connection support it
• Max duration: Up to 4 hours per session

Live video quality is network-dependent. Instagram re-encodes the stream on its end, so a stable connection matters more than camera specs here.

Aspect Ratio — Why It Actually Matters

What Aspect Ratio Means

Aspect ratio is the proportional relationship between a video's width and height. A 9:16 video is 9 units wide and 16 units tall — tall and narrow, built for phones held vertically. A 16:9 video is the opposite — wide, built for horizontal screens.

Getting this wrong doesn't just look bad. It means Instagram crops or letterboxes your video automatically, and you lose control over what the viewer sees.

Which Ratio to Use and When

• 9:16 — Reels, Stories, Live. No exceptions.
• 4:5 — Feed posts where you want maximum screen presence
• 1:1 — Feed posts where consistent, square framing suits the content
• 16:9 — Feed posts only; use when the horizontal composition is essential and you accept the reduced feed size

A common mistake is shooting in 16:9 on a DSLR or mirrorless camera and then trying to adapt it for Reels. You'll lose significant width if you crop to 9:16. If Reels is the destination, plan for vertical framing before you shoot.

Instagram Video Resolution and Compression

Minimum vs. Recommended Resolution

Instagram sets a minimum upload resolution of 720p. Below that, the platform rejects the file or heavily degrades it.

The recommended resolution across all formats is 1080p. Uploading at 4K doesn't help Instagram re-encodes everything down to 1080p on its servers anyway. You're not getting any visual benefit from uploading above that threshold; you're just uploading a larger file.

How Instagram Compresses Video on Upload

Every video uploaded to Instagram gets re-encoded. This is standard platform behaviour — the same happens on YouTube, TikTok, and most other social platforms.What this means practically: exporting your video at a very high bitrate doesn't prevent compression.

What it does do is give Instagram's encoder more data to work with, which can result in a slightly cleaner output. Exporting at too low a bitrate, on the other hand, means Instagram is re-encoding an already-degraded source — and the result shows.

Teams that produce high volumes of social content commonly report that exporting at 1080p, H.264, with a bitrate between 4,000–5,000 kbps gives consistently clean results across all Instagram placements.

Instagram Video Format — Export Checklist

Before you upload, run through this:

Setting	Recommended Value
Container	MP4
Video Codec	H.264
Audio Codec	AAC
Resolution	1080p (format-specific)
Frame Rate	30fps (or 60fps for action)
Bitrate	3,500–5,000 kbps
Max File Size	Under 4GB
Aspect Ratio	Match your placement type

Common Mistakes to Avoid

• Uploading 16:9 to Reels — Instagram will crop it, usually badly
• Ignoring safe zones — UI overlays cover roughly the top and bottom 14% of the frame on Reels and Stories
• Exporting above 4GB — Instagram will reject the file silently on some devices
• Using unsupported codecs — HEVC (H.265) has inconsistent support; stick to H.264
• Exporting at too low a bitrate — compression artifacts become visible after Instagram re-encodes

Conclusion

Match your format to your placement, export as MP4 with H.264 and AAC, and keep everything at 1080p. Reels and Stories are 9:16. Feed posts support 4:5, 1:1, and 16:9. Get the aspect ratio right before you shoot — fixing it in post costs quality.

Frequently Asked Questions

What is the best file format for Instagram video?

MP4 with H.264 video codec and AAC audio is the recommended format. It's widely compatible, exports cleanly from all major editing tools, and Instagram processes it reliably.

What aspect ratio should I use for Instagram Reels?

9:16 vertical. Resolution should be 1080×1920. Keep important text and visuals away from the top and bottom edges where Instagram's UI overlays appear.

Can I upload a 16:9 video to Instagram?

Yes, but only to feed posts. On a feed post it will display with reduced vertical space. If you try to use a 16:9 video for Reels, it will be cropped to 9:16 and you'll lose the sides of the frame.

What is the maximum file size for Instagram video?

4GB. Most standard exports come in well under this, but if you're uploading long-form feed videos at high bitrates, it's worth checking before upload.

Does Instagram reduce video quality when you upload?

Yes. Instagram re-encodes every uploaded video. Exporting at 1080p with a bitrate of 3,500–5,000 kbps gives the encoder enough data to produce clean output.
