🚨 Why CapCut Shows “File Not Supported”

Understanding the cause helps you solve it quickly. Here are the most common reasons behind the error:

1. Unsupported File Format or Codec
   • CapCut may not recognize your video’s internal codec even if it’s labeled as .mp4 or .mov.
   • Example: MP4 files using HEVC (H.265) may fail while H.264 ones work fine.

2. Very High Resolution or Bitrate
   • Ultra HD or 4K/8K videos can exceed CapCut’s limits.
   • Large files often crash or fail to import properly.
3. Corrupted or Incomplete File
   • Files not fully saved or damaged during transfer can trigger the error.
4. Outdated App Version or OS Conflict
   • Older CapCut apk builds sometimes don’t support new file standards.
5. Storage or Permission Problems
   • Insufficient storage or missing access permission can block imports.

⚙️ Step-by-Step Fixes for “File Not Supported” Error

Try these solutions in order. Each one addresses a real cause of the problem.

1. ✅ Check the File Format & Codec

CapCut officially supports:

MP4, MOV, M4V, AVI, MKV, and WebM

If your file has another format or uses a rare codec, CapCut may reject it.

Solution:

• Convert the video using a reliable converter.
• Choose H.264 (video) and AAC (audio) codecs — these work best with CapCut.
• After conversion, try importing again.

2. 🎬 Re-Export the File from the Source

If your clip came from another app or software (like VN, Premiere Pro, or screen recorder), re-export it:

• Set resolution to 1080p (Full HD)
• Format: MP4 (H.264)
• Bitrate: between 5,000–10,000 kbps

Then try importing it again into CapCut.

---

3. 📉 Reduce Resolution or File Size

4K and 8K clips often cause compatibility errors.
Fix it by downscaling:

• Convert to 1080p or 720p using a converter like HandBrake or MiniTool Video Converter.
• Ensure the new file size is smaller than 1 GB for mobile users.

---

4. 🧹 Free Up Storage & Clear Cache

Low storage or corrupted cache data can cause file import failures.

For Android:

• Go to Settings → Apps → CapCut → Storage → Clear Cache
• Ensure at least 1–2 GB free space on device.

For iPhone:

• Offload CapCut (Settings → General → iPhone Storage → CapCut → Offload App)
• Then reinstall it.

---

5. 🔄 Update CapCut to the Latest Version

Always use the latest CapCut version:

• Open the Google Play Store or Apple App Store
• Search for “CapCut”
• Tap Update if available

New updates often fix hidden bugs and add compatibility for new file types.

---

6. ♻️ Reinstall CapCut (Last Resort)

If none of the above works:

1. Back up your projects (export them first).
2. Uninstall CapCut.
3. Reinstall it from the official store.
4. Try importing your file again.

This refreshes permissions and removes broken configurations.

---

7. 🧪 Test with a Simple File

Import a small 1080p MP4 video you know works.

• If it imports successfully → your previous file was the issue.
• If it still fails → there’s a deeper issue with the app or device.
