Best Export Settings for Instagram Reels, TikTok, and YouTube Shorts (iPhone Guide)
Short-form video apps all re-encode your uploads. If you export with the wrong size, frame rate, or codec, the platform will compress your clip harder—softening details, adding banding, or introducing blocky motion. The goal is to export a file that matches what the app wants, so it does minimal extra work.
This guide gives you a clean, repeatable export preset for iPhone and explains the platform limits so you can avoid unnecessary quality loss.
The One Export Preset That Works Everywhere
If you want a single export preset that works for Reels, TikTok, and Shorts, use this:
Universal Vertical Export Preset
Resolution: 1080 x 1920 (9:16) Frame rate: 30 fps (use 60 fps only for action or slow-motion edits) Codec: HEVC (H.265) if supported, otherwise H.264 Bitrate: 8-12 Mbps (raise to 12-16 Mbps for fast motion or lots of fine detail) Audio: AAC, 48 kHz
Why this works: 1080x1920 is the most widely supported vertical resolution across platforms. It's high enough to look sharp on modern phones, but not so large that platforms aggressively downscale or recompress. 30 fps is the safest default and matches what most apps expect for smooth playback.
Pro Tip
If you shot 4K, don't export 4K for Shorts/Reels unless you have a specific reason. Most platforms downscale to 1080p anyway. Exporting at 1080p gives you more control over the final quality.
Platform Specs (What Each App Accepts)
The official specs below help you avoid disallowed settings that trigger extra compression or failed uploads. These limits can change, so check the app if something seems off.
| Platform | Key Limits | Notes |
|---|---|---|
| TikTok | MP4/MOV/WebM, H.264/H.265/VP8/VP9, 23-60 fps, 360-4096 px, up to 4 GB, up to 10 minutes via API | Most accounts still default to 3 minutes; some have 5-10 minute uploads. |
| Instagram Reels | 9:16 vertical, min 720x1280, 1080x1920 recommended, 30 fps minimum | Use 1080x1920 to minimize resampling. |
| YouTube Shorts | Vertical or square, up to 3 minutes | Stick to 9:16 and under 3 minutes for best labeling. |
HEVC vs H.264: Which Export Codec Should You Choose?
Both codecs work on modern platforms, but HEVC is more efficient. Apple notes that HEVC provides better compression and smaller file sizes than H.264 at the same quality. If you export HEVC, you'll get smaller files and faster uploads—especially helpful when you're on cellular or uploading from a hotel Wi‑Fi connection.
If a platform or workflow doesn't accept HEVC reliably, export H.264 instead. It's universally compatible and still looks great when you keep your bitrate in the 8-12 Mbps range for 1080p.
HEVC (H.265)
- •Better compression at same quality
- •Faster uploads for long clips
- •Ideal for storage on iPhone
- •Great if the app accepts HEVC
H.264
- •Works everywhere
- •Still sharp at 1080p
- •Best for older devices
- •Good when HEVC fails
Step-by-Step: Export the Right Way on iPhone
Pick your final cut: do trims, music, and text overlays first. Export from your final timeline, not raw clips.
Set the universal preset: export at 1080x1920, 30 fps, and 8-12 Mbps. Use HEVC if available, otherwise H.264.
Check motion-heavy scenes: if the clip has fast motion or lots of fine detail, increase bitrate to 12-16 Mbps.
Upload the export directly: avoid re-saving inside the social app when possible to prevent extra compression.
What About 60 fps and HDR?
Use 60 fps only if your clip really benefits from it: sports, fast pans, or slow‑motion edits. Otherwise, 30 fps keeps file sizes smaller and is more universally supported.
For HDR footage, keep it if the platform preserves HDR (some do, some don't). If you see washed-out colors after upload, export SDR instead. SDR is more predictable across devices and apps.
Avoid These Common Mistakes
- Uploading 4K when the platform will downscale anyway
- Exporting at 24 fps (can look juddery in apps that expect 30)
- Using very low bitrates (below 6 Mbps) for 1080p
- Re-saving inside the app, which triggers extra compression
The Storage Angle (Why This Matters)
Short-form content adds up fast. A day of shooting can turn into dozens of clips, and you'll feel the storage pressure quickly. Exporting with HEVC and the right bitrate can shrink files significantly while keeping quality high, which means:
- Faster uploads
- Less iPhone storage used
- Easier backups
- Cleaner archives
Best Way to Batch-Export for Shorts
If you're exporting multiple clips at once, you want a compressor that can batch‑process with consistent settings. HEVCut was built for exactly this workflow—select multiple videos, apply one preset, and export clean HEVC or H.264 files optimized for sharing.
If you're ready to shrink your files and keep them sharp for Reels, TikTok, and Shorts, try HEVCut and export with a single, consistent preset.
