Файл R3D

.r3d files are used by high-definition digital cinema cameras made by RED Digital Cinema, capable of recording at 4K, 6K, and 8K resolutions.

Files with the .r3d extension store raw sensor data captured with RED cameras. Frames are encoded using the REDCODE wavelet-based compression codec at a selectable compression ratio - from near-lossless 2:1 up to 22:1 - so the footage retains far more detail than conventionally compressed video formats. Long recordings are automatically split into multiple numbered .r3d segments (for example A001_C001_001.R3D, _002.R3D) that together form one continuous clip.

RED cameras are used mostly in cinematography and broadcast production. In 2007 the first model in the series, Red One, introduced capturing video at 4K resolution. The emergence of cameras using the .r3d format revolutionized digital cinematography. By 2018 RED had introduced bodies capable of recording video at 8K resolutions, far exceeding the earlier 4K standard. Each .r3d clip stores Bayer pattern sensor data, which means color rendering, white balance, and ISO are decided non-destructively in post-production rather than baked into the file. Look and metadata settings travel alongside the clip in a sidecar .rmd file, keeping the original sensor data untouched.

Because .r3d is an acquisition format rather than a delivery format, finished projects are exported to containers such as .mov or .mxf before distribution. To work with .r3d footage, a 4K or higher monitor is recommended to fully appreciate the fidelity that the raw capture provides.
