Best Practices for CPT to DPX Conversion

→Before converting CPT to DPX, decide whether you need maximum quality or smallest file size — this determines which format truly fits
→Save a master copy in a lossless format before converting to DPX — you cannot recover detail lost during lossy compression
→Check the color profile: CPT images may use a wider gamut than DPX supports, causing a visible shift after conversion
→Resize images to the final display dimensions before converting — this avoids unnecessary processing of oversized files
→Run a single test conversion first to verify quality meets your standards
→Strip unnecessary metadata to reduce file size after conversion

Troubleshooting CPT to DPX Conversion

!Converting CPT to DPX gives blurry output → increase the quality setting before conversion
!Colors look different in DPX than CPT → check color profile mismatch (sRGB vs Adobe RGB)
!File size changed more than expected → DPX uses different compression, file size differences of 2-5x are normal
!Transparent areas in CPT turned white in DPX → DPX may not support transparency
