Part 2. Why is My CapCut Video Upscaler Not Working

If you’ve tried improving your footage but noticed that your CapCut video upscaler isn’t giving the results you expected, it happens more often than you think. Many users ask, “Why is my CapCut upscaler not working?” or even Can CapCut upscale video consistently?” The truth is that several common issues can affect the upscaling process, but they’re usually easy to resolve. Here are a few potential explanations and remedies to consider:

1. Outdated Version of the App

Reason: The latest upscaling features might not be compatible with older versions of CapCut.

Solution: Update CapCut to the most recent version on your app store. Once you have updated, restart the app and retry.

2. Unsupported Device or Limited Processing Power

Reason: Upscaling requires high processing power, and some devices, such as phones or PCs, may struggle to handle it.

Solution: Close background apps before using CapCut, or try using the desktop version for better performance.

3. Low-Resolution Source Video

Reason: If your original footage is too low in quality, the AI has limited data to enhance it.

Solution: Try using footage that’s at least 720p. For poor-quality videos, consider download and give Aiseesoft VidHex a try, which offers more advanced AI-enhanced features.

4. Poor Internet Connection (for Online Editing)

Reason: CapCut relies on cloud processing for certain features, particularly in the web version.

Solution: Switch to a stable Wi-Fi connection or edit offline using the downloaded app.

5. Cache problems or glitches in the app

Reason: The CapCut upscaling tool may not work properly due to accumulated cache files.

Solution: To improve CapCut's performance, either reinstall the app or clear its cache in the settings.

6. Incorrect Export Settings

Reason: If you don't explicitly choose a higher output, the video may occasionally export at its original resolution.

Solution: Before exporting, go to Settings, click Resolution, and select 1080p or 4K. Ensure the Bitrate is set to high.
