CIN to PNG Converter

CIN (Cineon) is a 10-bit logarithmic image format Kodak built in the early 1990s to represent scanned film frames for digital effects work.

Kodak developed the Cineon system to bridge physical film and digital compositing: scan a negative, edit or add effects digitally, then record the result back onto film without a visible generation loss. To make that round-trip work, the Cineon file format stores each pixel as a 10-bit logarithmic value that mirrors film density rather than a straight linear brightness — the same encoding scheme film stock itself uses — so highlights that would clip in an ordinary 8-bit format stay recoverable. The Cineon product line was discontinued in the late 1990s, but the file format it introduced lived on as the direct basis for DPX, the SMPTE-standardized format that replaced it in most modern VFX pipelines.

PNG is a lossless image format built for sharp edges, flat colors, and transparency — think logos, screenshots, and UI graphics rather than photos.

PNG (Portable Network Graphics) was created in the mid-1990s as a free, patent-unencumbered replacement for GIF, and it inherited GIF's lossless approach while adding full 24-bit color and an alpha transparency channel. Because nothing is thrown away during compression, a PNG can be re-saved indefinitely without ever degrading — a real advantage for screenshots, diagrams, and anything with text or hard edges, where JPEG's compression tends to introduce visible smudging. The cost is file size: for photographic content, a PNG is typically several times larger than an equivalent JPEG, which is why most photo libraries still default to JPEG and reserve PNG for graphics.
