title: 'AV1R: ''AV1'' Video Encoding for Biological Microscopy Data'
version: 0.1.3
doi: 10.32614/CRAN.package.AV1R
abstract: 'Converts legacy microscopy video formats (H.264/H.265, AVI/MJPEG, TIFF
  stacks) to the modern ''AV1'' codec with minimal quality loss. Typical use cases
  include compressing large TIFF stacks from confocal microscopy and time-lapse experiments
  from hundreds of gigabytes to manageable sizes, re-encoding MP4 files exported from
  ''CellProfiler'', ''ImageJ''/''Fiji'', and microscope software with approximately
  2x better compression at the same visual quality, and converting legacy AVI (MJPEG)
  and H.265 recordings to a single patent-free format suited for long-term archival.
  Automatically selects the best available backend: GPU hardware acceleration via
  ''Vulkan'' ''VK_KHR_VIDEO_ENCODE_AV1'' or ''VAAPI'' (tested on AMD RDNA4; bundled
  headers, builds with any ''Vulkan'' SDK >= 1.3.275), with automatic fallback to
  CPU encoding through ''FFmpeg'' and ''SVT-AV1''. User controls quality via a single
  CRF parameter; each backend adapts automatically (CPU and Vulkan use CRF directly,
  VAAPI targets 55 percent of input bitrate). TIFF stacks use near-lossless CRF 5
  by default, with optional proportional scaling via tiff_scale (multiplier or bounding
  box, aspect ratio always preserved). Small frames are automatically scaled up to
  meet hardware encoder minimums. Audio tracks are preserved automatically. Provides
  a simple R API for batch conversion of entire experiment folders.'
