Thanks for that!You rely mostly on default values for your cmd line. It's ok mostly except for the temp directory which defaults to system. I would personnaly avoid grinding my OS file system. Also if your movie is on another drive it creates a lot of IO.
My running batch copies the movie to the dir where lada is installed (not my system drive) and I set the temporary-directory in the same drive... then copies it back, renaming the whole folder files including the nfo update.
FYI this is what I use as a cmd line...
Code:lada-cli --input "PathTo/movie.mp4" --output "PathTo/movie [RL].mp4" //or you naming convention --temporary-directory "G:\tmp" --device "cuda" --encoding-preset hevc-nvidia-gpu-hq --mosaic-restoration-model basicvsrpp-v1.2 --max-clip-length 400 --mosaic-detection-model v4-accurate
I actually do have my system temp directory on a separate NVMe SSD for the reasons you mention.
