What is DPX?

Digital Picture Exchange (DPX) is a professional film and video frame format used in visual effects and digital cinema workflows.

What is FITS?

Flexible Image Transport System (FITS) is a scientific data format used primarily in astronomy for storing and transmitting images and datasets.

When Should You Use DPX vs FITS?

DPX vs FITS: Key Differences

• •DPX uses lossless compression while FITS uses lossless compression — both take the same approach to file size management.
• •Since both DPX and FITS use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •How transparency is handled: FITS supports transparency, so alpha information is preserved during conversion.
• •Storage footprint: Large, 1-10MB per 2K film frame for DPX vs Varies from 1MB to several GB for FITS.
• •DPX is optimized for film scanning, vfx production, cinematography while FITS is designed for astronomy, scientific imaging, research — choose based on your specific workflow needs

Advantages of DPX

• ✓DPX uses lossless compression tailored for Film scanning, VFX production, cinematography.
• ✓DPX is supported natively on virtually every device, browser, and operating system.
• ✓DPX files are bit-for-bit perfect, preserving every pixel and sample for professional work.
• ✓DPX integrates seamlessly with all major creative tools and workflows.

Advantages of FITS

• ✓The lossless nature of FITS means file sizes stay reasonable while handling Astronomy, scientific imaging, research efficiently.
• ✓From mobile devices to enterprise servers, FITS is recognized and supported everywhere.
• ✓The trade-off for FITS's perfection is larger files — but for archival work, it is worth every megabyte.
• ✓FITS is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Common Use Cases for DPX to FITS Conversion

• Newsletter graphics
• Video thumbnail creation
• Certificate and badge design
• Websites and online content
• Print materials and publications
• Social media posts and ads

Industry Applications

Best Practices for DPX to FITS Conversion

• →When converting DPX to FITS, check whether FITS supports transparency — if not, your transparent areas will be filled with a solid color
• →Use FITS for maximum quality archival and DPX for lossless workflows
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting DPX to FITS Conversion

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