%description
Converts microscopy video and image data (H.264/H.265, AVI/MJPEG, TIFF
stacks) to the 'AV1' codec for compact storage, and archives 16-bit image
stacks and videos losslessly in the 'FFV1' format. Encoding runs on the
GPU via 'Vulkan' or 'VAAPI' when available and falls back to the CPU
through 'FFmpeg' and 'SVT-AV1'. Whole experiment folders can be converted
at once.
