DPX vs BPG: Key Differences

  • •DPX and BPG diverge on compression: lossless compression for the source, lossy compression for the target.
  • •Moving from DPX (lossy) to BPG (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
  • •How transparency is handled: BPG does not support alpha channels — transparent areas in the source will become opaque.
  • •DPX files are typically Large, 1-10MB per 2K film frame while BPG files range 30-50% smaller than JPEG at same quality
  • •DPX is optimized for film scanning, vfx production, cinematography while BPG is designed for web images with superior compression — choose based on your specific workflow needs

Best Practices for DPX to BPG Conversion

  • →Before converting DPX to BPG, 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 BPG — you cannot recover detail lost during lossy compression
  • →Check the color profile: DPX images may use a wider gamut than BPG 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 DPX to BPG Conversion

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