Troubleshooting PEF to R3D Conversion

!R3D shows visible compression artifacts → lower the compression level or switch to a lossless variant
!The converted R3D image looks washed out → the source PEF likely uses a wider color space than R3D supports
!R3D file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
!Text in the converted R3D looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
