NanoEncoder docs
Here we’ll detail the usage and behavior of NanoEncoder, as well as explain a bit about h.265 and its features.
Usage
nen optimize '/path/to/videos' # Re-encode directory with HEVC (h.265)
nen health '/path/to/videos' # Compare original vs optimized quality
nen purge '/path/to/videos' # Remove original files (sends to trash)
nen untag '/path/to/videos' # Remove NanoEncoder tags from filenames
If you trust CRF to do a “good enough” job, or if you have limited disk space (i.e. you can’t store both the original and optimizes versions at the same time), you can add the --replace flag. This handles most of the process, aside from the healthcheck.
nen optimize --replace '/path/to/videos' # Optimize with default CRF, but delete original and untag new files, effectively "replacing" the file with an HEVC version.
