kandi X-RAY | canon_cr3 Summary

canon_cr3 is a Python library. canon_cr3 has no bugs, it has no vulnerabilities, it has build file available, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

The Canon CR3 format is mainly based on the ISO Base Media File Format (ISO/IEC 14496-12), with custom tags, and the new 'crx' codec. Some tags contains TIFF structures (like IFDs, Makernotes...). Phil Harvey, the author of ExifTool, already identified some custom TIFF tags: Canon CR3 tags. Canon Raw v2 is described here: and Canon CRW here: The CR3 file format and its new CRX codec support both lossless 'raw' and lossy 'craw' compressions. CR2, the TIFF based format is no more used by the M50 or EOSR, even with lossless 'raw' compression. The CRX codec has been reverse engineered by Alexey Danilchenko, implemented in FastRawViewer 1.5.1 and source code was released in october 2019, see 'craw' means 'compact raw'. The CR3 format also supports dual pixel pictures, sequence of images ("roll" created using Raw burst mode) and movie (CRM). Roll files (CSI_*.CR3) can contains up to 70 pictures (for M6 Mark II).
