Remotion Troubleshooting — Common Errors and Solutions
Collection of real-world errors: slow rendering, delayRender timeout, useState infinite loop
Common Remotion development errors and solutions.
1. Slow rendering: Increase --concurrency or use Remotion Lambda.
2. delayRender timeout: Always call continueRender(handle) — including in catch blocks.
3. useState infinite loop: Remotion re-renders every frame, so useState triggers infinite loops. Use useCurrentFrame() + interpolate() instead.
4. CSS animations not working: Remotion renders frames independently, so CSS transitions don't sync. Use spring() and interpolate().
5. Lambda flickering: Lower concurrency, test locally first, update Remotion version.
How It Works
Check error message: identify cause by keywords like delayRender, too many renderings, timeout
Check useState usage: frame-based values must use useCurrentFrame() + interpolate()
Verify delayRender calls: check that continueRender() is called in all branches (success/failure)
Check CSS animation/transition usage: replace with Remotion API
For rendering speed issues, consider --concurrency option or Lambda adoption
Pros
- ✓ Most errors follow patterns so solutions are quick
- ✓ Can pinpoint and debug problem frames in Remotion Studio
Cons
- ✗ Lambda-related issues may be difficult as they require AWS infrastructure knowledge
