Release SubSync 1.0.2 (fork) · Tag: v1.0.2 · Sefzz15/subsync

A modernized fork of sc0ty/subsync by Michał Szymaniak.

This release makes the per-subtitle (piecewise) sync mode introduced in 1.0.1 actually reliable, and puts its controls in your hands.

Piecewise sync no longer chases noise. Correlation points are individually noisy (a mismatched word can be off by a second), and the old warp retimed every line to the local median of a few of them — injecting a spurious sub-second wobble on top of the correct timing. It now anchors on the global linear fit and applies a local correction only where the nearby points are dense and significantly, consistently off that line (a real cut/ad-break/mid-file resync), shrinking everything else back to the line. On a real test file this cut the lines landing more than 0.5s off from 46% to 13%, while still following genuine resyncs.
Tunable from the GUI. Settings → Synchronization now exposes Piecewise window (s), Piecewise min local points, and Piecewise significance (σ), each with an info tooltip. Higher significance stays closer to a plain linear sync; lower follows the points more eagerly.
Piecewise in batch processing. The batch window has a new "Sync method" dropdown (Linear / Per-subtitle piecewise).
