Changelog

v1.0.1 — 2026-10-14

Each release carries its documentation as docs-vX.Y.Z.tar.gz for docs.pitomd.com/pconv: install, six guides with real commands and output, the command line, the JSON outputs, the library API and this changelog.
A library example, examples/library.rs, that probes, plans and runs a conversion.

pconv is 1.0.0: the same command line, JSON output and exit codes as 0.14.2, now with a stable version number.
The README shows each feature with its own clip and leads with measured numbers: GIFs 2.5× smaller and 1.5× faster than ffmpeg’s palettegen and paletteuse on a terminal clip, joins 52× faster by stream copy than by re-encoding, an 843 KB binary.

GIF frames no longer break into blocks and dither specks on a slow change under the tolerance (a focus pull, a fade, a slow pan): the frame is redrawn whole when such drift covers a fifth of it, and the dithering error is capped at 16 levels.

GIFs without alpha store only the rectangle that changed in each frame, unchanged pixels transparent, within a tolerance of 12 levels (4 with best): a 1280-wide, 15 fps desk clip goes from 6.1 MB to 1.6 MB and encodes in 1.2 s instead of 3.4 s.

pconv runs on Windows (x86_64) and macOS (Apple Silicon) with the system’s ffmpeg, as well as Linux.
On Windows, Ctrl-C and Ctrl-Break stop ffmpeg’s whole process tree and leave no partial file.
A progress line on a terminal: a braille spinner, the step, a dotted bar, the percent, the speed in fps and the ETA.
--no-progress turns the line off; --json, TERM=dumb and a piped stderr never draw it, so scripts and agents read only the result.
Every tag’s GitHub Release carries binaries for Linux x86_64, Windows x86_64 and macOS arm64, with SHA256SUMS.
The README gives install steps for Linux, Windows and macOS, what each needs at run time, and how scripts and agents drive pconv.
The README’s GIFs show the progress line, led by a new progress clip, with another for scripts and agents.

--profile fast (VA-API) is Linux only: elsewhere pconv refuses it with one line naming balanced and best, and pconv profiles says so.
CI runs the full gate on Linux, Windows and macOS, on every branch, nightly and by hand.
The release binary is fully stripped.

The first public release: H.264 and VP9 deliveries with the colour right (VP9 keeps alpha), looping GIF and WebP README clips, loudness levelling to a LUFS target, and joining clips by stream copy or re-encode, over ffmpeg on Linux.
