JLS to CIN Conversion: FAQ

What are JLS files?

JPEG-LS .jls is a lossless (and optionally near-lossless) image-compression standard that uses the lightweight LOCO-I predictor plus context-adaptive run-length coding to capture local pixel correlations with very low complexity. It typically delivers higher compression ratios than baseline JPEG while decoding quickly and requiring little memory, making it well-suited for medical, scientific, and embedded imaging where exact pixel fidelity and minimal latency are vital.

What are CIN files?

The CIN or Kodak Cineon format is a raster graphics format originally associated with the process of film editing and production using the Cineon System designed by Kodak, developed during the 1990s. Though later on Kodak stopped producing this system, the CIN format remained popular especially in the process of creating visual effects. The format's main advantage is its ability to offer a high-quality rendering of scanned film negatives, thus allowing their future editing.
