vkdt

vkdt’s graph can connect multiple inputs and outputs, which suits image sequences and processing jobs that need more than a single linear adjustment chain. RAW files start with a default processing graph; the command-line tool replaces display nodes with export nodes when rendering it. That gives the graph a route to files as well as a screen preview. Hardware is part of the decision: processing uses Vulkan on the GPU. The documentation suggests 4 GB of video memory for a workable setup and at least 8 GB for large graphs or images above 50 MP, while noting that smaller-memory systems may run. Some codecs and metadata features also depend on the build.
