If your project suddenly looks laggy or slowed down, you may be facing the CapCut template running slow-motion issue. This usually happens when playback or rendering settings don't match the original template design, or when your device struggles to process effects in real time. In many cases, the video isn't actually slow—it just appears that way during preview or export.
Below are the hidden reasons and fixes for each platform.
📍 If the template running slow motion issue continues, please contact our support team for further assistance.
CapCut Online
Reasons
- Frame rate mismatch: The template may be designed for 60fps, but your project is running at a lower frame rate.
- Browser performance limitations: Heavy templates with effects may lag in the browser preview.
- Internet or cloud processing delays: Slow connections can affect playback smoothness.
Solutions
- Adjust frame rate settings: Match the template's original frame rate (e.g., switch to 60fps).
- Refresh the page: Reload the editor to clear temporary lag.
- Close extra tabs: Free up browser resources for smoother playback.
- Check internet stability: Use a stable connection for better performance.

Solutions
- Lower preview resolution: Reduce playback quality in the preview window.
