Sobre os arquivos RW2Comparativo de vantagens
GIF Vantagens
- Universal animation support — every browser, every chat app, every social network.
- Transparent backgrounds for compositing against any page color.
- Lossless for its limited palette — pixel-perfect at 256 colors.
- Self-contained: no codec, no browser plugin, no third-party player needed.
RW2 Vantagens
- Compact thanks to Micro Four Thirds sensor size.
- Hybrid photo/video workflow friendly on GH bodies.
- Supports 14-bit depth on Lumix S.
- Stable format since 2008.
Limitações
GIF Limitações
- Limited to 256 colors per frame — looks posterized on photographs.
- Dithering for color-rich images makes files huge (often 10× an MP4 equivalent).
- No audio track.
- Transparency is 1-bit (on/off) — no smooth alpha blending.
- Poor compression compared to modern formats (WebP, MP4, AVIF).
RW2 Limitações
- Proprietary — no public spec.
- Market share is niche; fewer tutorials.
- MFT sensor means less dynamic range than full-frame.
- Video-focused bodies mean some RW2 files are actually video-extracted frames with different artifacts.
