About CIN
Kodak made Cineon in the early 1990s for its system that scanned film, worked on it in a computer and recorded it back to film, and its files carried some of the first digital visual effects in feature films. DPX grew out of it and took its place, and archives and film scanners still hold reels of .cin frames.
A Cineon file is a header with the film's and the frame's facts, then each pixel's red, green and blue at 10 bits, three to a 32 bit word, as printing density: a log scale like film's own, with black at 95 and white at 685.
Filepeek reads it in your browser and turns printing density into light as Kodak's own system does, so a scan looks as it would printed, and Export saves the frame as PNG or JPEG. Show details lists its film, frame and the scanner that made it.

Questions
Why does a Cineon frame look gray and flat in other apps?
Its numbers are printing density, a log scale, and an app that shows them as they are shows a flat, gray picture. Filepeek turns them into light as Kodak's system does, from black at 95 and white at 685, or the points the file gives.
How do I convert CIN to PNG or JPEG?
Open it, then choose Export and Save as PNG or Save as JPEG.
Why does my .cin open as something else?
Quake II named its cinematics .cin too. A Cineon frame starts with Kodak's own mark, so Filepeek tells them apart and shows what any other .cin is.
