BMP vs CIN
Um comparativo detalhado de BMP Image e Kodak Cineon — tamanho de arquivo, qualidade, compatibilidade e qual escolher de acordo com seu fluxo de trabalho.
BMP Image
Raster & Vector ImagesBMP is an uncompressed raster image format native to Windows. Files are large but preserve exact pixel data with no compression artifacts. Rarely used on the web due to file size.
Sobre os arquivos BMPKodak Cineon
Raster & Vector ImagesCineon is a digital film format developed by Kodak for scanning and recording motion picture film. It uses logarithmic encoding to capture the full density range of film negative, preserving maximum tonal detail for post-production grading.
Sobre os arquivos CINComparativo de vantagens
BMP Vantagens
- Dead-simple format — trivially easy to read and write.
- Lossless and uncompressed — perfect bit-exact pixel storage.
- Universally supported in Windows applications since 1985.
- Supports 1, 4, 8, 16, 24, and 32-bit color depths.
CIN Vantagens
- 10-bit log color preservation.
- Film-scanning archival standard.
- DPX-compatible.
Limitações
BMP Limitações
- Enormous file sizes — no meaningful compression in typical use.
- Not a web format — browsers support it but nobody serves BMPs over HTTP.
- No metadata support (no EXIF, no ICC profile in practice).
- Multiple header versions mean "a BMP" is ambiguous — parsers must handle several variants.
CIN Limitações
- Legacy — DPX is the modern choice.
- No compression.
- Niche tooling.

PNG is better than BMP in almost every scenario since it provides lossless compression (smaller files), transparency support, and wider cross-platform use. BMP is mainly relevant for legacy Windows applications.
