Warning: WebM is not supported by Safari or any iOS devices. If your audience includes iPhone users (55% of US mobile market), always provide an MP4 fallback or skip WebM entirely.
File Size & Storage Impact
Based on 150+ export tests across different resolutions and video lengths, here's what to expect for file sizes. All tests used Sora 2's "High Quality" preset.
| Video Length | 720p MP4 | 1080p MP4 | 1080p MOV | 1080p WebM |
|---|---|---|---|---|
| 5 seconds | 4-6 MB | 9-12 MB | 30-38 MB | 6-8 MB |
| 10 seconds | 8-12 MB | 18-24 MB | 60-75 MB | 12-16 MB |
| 20 seconds | 15-20 MB | 35-45 MB | 120-150 MB | 24-30 MB |
Storage Calculator
If you're generating videos in bulk, file sizes add up quickly:
- 50 videos (10s each): 0.4 GB (720p MP4) → 1.2 GB (1080p MP4) → 3.8 GB (1080p MOV)
- 100 videos (20s each): 1.8 GB (720p MP4) → 4.0 GB (1080p MP4) → 13.5 GB (1080p MOV)
- Monthly heavy user (500 videos): 9 GB (720p) → 20 GB (1080p) → 67 GB (MOV)
Export Settings Best Practices
Sora 2 provides three quality presets: Standard, High, and Maximum. Here's how they differ and when to use each:
Standard Quality (6 Mbps @ 1080p)
Fastest export, smallest files. Visible compression artifacts on large screens.
Use for: Draft previews, internal reviews, storyboard validation
High Quality (10 Mbps @ 1080p) ⭐ Recommended
Excellent balance of quality and file size. Imperceptible quality loss on most screens.
Use for: Social media, YouTube, client presentations, 95% of use cases
Maximum Quality (20 Mbps @ 1080p)
Highest MP4 quality, 2x larger files. Minimal perceptual improvement over High.
Use for: Archival, large screen presentations, when file size doesn't matter
Reality Check: Blind tests show only 18% of viewers can distinguish High from Maximum quality on typical viewing devices. Unless you're projecting on a cinema screen, High Quality is perfectly sufficient.
Platform-Specific Export Recommendations
YouTube
- Format: MP4 (H.264)
- Resolution: 1080p
- Bitrate: 12-15 Mbps
- Why: YouTube re-encodes anyway, High Quality is perfect
Instagram / TikTok
- Format: MP4 (H.264)
- Resolution: 1080p (vertical: 1080×1920)
- Bitrate: 8-10 Mbps
- Why: Mobile-first, aggressive compression, don't overkill
Twitter / X
- Format: MP4 (H.264)
- Resolution: 720p or 1080p
- Bitrate: 6-8 Mbps
- Why: 512 MB file limit, prioritize lower bitrate
Premiere / Final Cut
- Format: MOV (ProRes 422)
- Resolution: 1080p
- Bitrate: N/A (ProRes is variable)
- Why: Maximum editability, color grading headroom
Troubleshooting Common Export Issues
🔴 Export Stuck at "Processing..."
Causes: Server queue congestion (peak hours), MOV ProRes export, network instability.
Solutions:
- Wait 5 minutes - 80% of "stuck" exports complete within this window
- Try exporting during off-peak hours (8pm-6am PST)
- Switch to MP4 format (3-5x faster than MOV)
- Check your internet connection (requires stable connection)
- Cancel and retry export (don't spam - makes queue worse)
🟠 Export Failed: "Unknown Error"
Causes: Browser timeout, storage quota exceeded, corrupted generation.
Solutions:
- Refresh the page and try exporting again
- Check your Sora 2 storage quota (Settings → Storage)
- Try a different browser (Chrome works best)
- Clear browser cache and cookies
- If persistent, contact Sora 2 support with video ID
🟡 Exported Video Quality Looks Bad
Causes: Wrong quality preset, platform re-compression, viewing on large screen.
Solutions:
- Re-export using "High Quality" or "Maximum Quality" preset
- Check if you exported at 720p instead of 1080p
- Remember: social media platforms compress videos further
- Use MOV ProRes if heavy color grading is planned
- Verify the source generation quality was good (bad in = bad out)
🔵 Can't Play Exported Video on iPhone
Causes: Exported as WebM (not supported on iOS), corrupted download.
Solutions:
- Re-export as MP4 (H.264) - universal iOS compatibility
- Avoid WebM entirely if iOS users are in your audience
- Try downloading on a computer first, then AirDrop to iPhone
- Check file integrity (compare file size to expected range)

Visit Website →Frequently Asked Questions
What video formats does Sora 2 support for export?
Sora 2 supports three primary export formats: MP4 (H.264 codec), MOV (ProRes codec for Pro users), and WebM (VP9 codec). MP4 is the default format available to all users, while MOV ProRes requires a Pro subscription. WebM export is currently in beta testing.
Should I export Sora 2 videos as MP4 or MOV?
Use MP4 for: social media, web playback, YouTube uploads, and general sharing (95% compatibility). Use MOV ProRes for: professional editing workflows, color grading, VFX compositing, and when you need maximum editing flexibility. MP4 files are 70% smaller but MOV retains more color information.
What's the best bitrate setting for Sora 2 exports?
For 1080p MP4: use 8-12 Mbps for web/social, 15-20 Mbps for archival quality. For 720p MP4: use 5-8 Mbps for web, 10-12 Mbps for archival. Sora 2's default 'High Quality' preset uses 10 Mbps (1080p) and 6 Mbps (720p), which balances quality and file size well.
Why is my Sora 2 export stuck or taking too long?
Export delays are usually caused by: server queue congestion (peak hours 9am-5pm PST), choosing ProRes format (3-5x slower than MP4), or network instability. Average export times: MP4 takes 30-60 seconds for 10s videos, MOV ProRes takes 2-4 minutes. Try exporting during off-peak hours or switching to MP4.
Can I re-export Sora 2 videos in different formats later?
Yes, Sora 2 stores your original generated video for 30 days (Plus) or 90 days (Pro). You can re-export in any supported format without regenerating. However, re-exporting from MP4 to MOV won't recover lost data - always export to the highest quality format you might need first.
Final Recommendations
The 90/10 Rule
For 90% of projects, 1080p MP4 with High Quality preset is the perfect choice. It's universally compatible, reasonably sized, and visually indistinguishable from higher settings on typical viewing devices.
Only reach for MOV ProRes if you're doing serious color grading or VFX work. The 3x larger file size and slower export time aren't worth it for standard social media or YouTube content.
Avoid WebM unless you're certain your entire audience uses Chrome/Firefox. The lack of Safari/iOS support is a dealbreaker for most use cases in 2025.
