Quick Tips

Quality vs Speed

// Fast preview quality
RenderQuality.preview  // Lower quality, faster

// Balanced
RenderQuality.standard  // Good quality, reasonable speed

// Maximum quality
RenderQuality.high  // Best quality, slower

Memory Management

  • Use saveLayer sparingly (prefer Fluvie's Fade widgets)
  • Match image resolutions to output size
  • Pre-trim videos before embedding
  • Clear caches between renders

Debugging

Enable debug frames to inspect individual frames:

EncodingConfig(
  debugOutputFrames: true,  // Saves individual frame PNGs
)
