1-Click SeedVR 2.5 — Release Notes (v1.9.48b → v1.9.54b)

Everything new since v1.9.47b.

v1.9.54b — last_used.json relocation

last_used.json moved next to config.json (project root) — processing
settings and app settings live side by side; named presets stay in the
configurable presets directory.

Temp moved to C:\1Click_SeedVR2.5\temp — all transient work (queue
files, previews, chunk runs) lives with the other shared assets
(python_embeded, models, presets), configurable via the Temp
directory setting.
"Log directory" setting row in Settings — where app.log,
error.log and failure reports are written.
Debug output ON by default.
access.log — every CLI log line is appended (timestamped) across
sessions. Show Log opens with previous-run history (last 3000 lines)
instead of a blank window; Clear wipes both view and file.
Send Logs button on the error dialog — zips error.log,
access.log, app.log and config.json and emails the archive to the
developer fully in the background. SMTP credentials are embedded in the
binary (obfuscated, never shown in the UI) — zero configuration.

One config.json, in the project root only. The EXE (inside dist\)
anchors one level up, so source runs and the frozen EXE read/write the
same file — dist\config.json and dist\temp are gone for good.
config.json contains only the Settings-dialog values (runtime paths,
temp/presets/log directories, alarm, systray, session I/O).
Processing settings (batch, tiles, model, offloads…) live in
presets\last_used.json — separated by design.
New log\ directory for app/error/failure logs, configurable via the
"Log directory" setting.
Presets directory is configurable ("Presets directory" setting,
default C:\1Click_SeedVR2.5\presets).

SeedVR2_GUI.exe → 1-Click_SeedVR_2.5.exe (InternalName and
OriginalFilename metadata updated as well).

Display name is now "1-Click SeedVR 2.5" (window title, tray tooltip,
EXE file description, product name).

New System tray on/off switch in Settings (below Alarm sounds),
persisted in config.json, default on.
- ON: closing the window hides the app to the tray; processing
  continues in background; full quit via the tray menu.
- OFF: no tray icon; closing the window really quits the app.
Applies immediately — no restart needed.

The raw RGB pipe reached NVENC and was encoded as GBR 4:4:4
(Main 4:4:4 + identity matrix) — many editors/players misinterpret it
and shift colors. The writer now forces -pix_fmt yuv420p plus an
explicit bt709 RGB→YUV matrix (-vf scale=out_color_matrix=bt709:out_range=tv),
so output is Main / yuv420p / bt709 / tv — the same standard combo
ComfyUI writes. Verified with a real NVENC encode + ffprobe.
Image-sequence export gets the same matrix fix. RGB targets (FFV1,
ProRes 4444) unaffected.

Failures no longer show a bare "Exit code 1": the dialog opens with
details expanded, headed by the most meaningful error line, and the full
report (command + last 100 log lines) is saved to
log\cli_failure_<timestamp>.log with Copy-to-Clipboard.

Success/failure alarms now speak via Windows SAPI ("Processing completed
successfully." / "An error occurred during processing."), falling back to
the old chime when no voice is installed.

Removed the non-functional "Side by Side" preview button.
7B config selection is case-insensitive — a file named with an uppercase
"7B" no longer silently loads the 3B config and fails with a confusing
architecture mismatch. Dry-run structure test passes for all 9 registered
DiT models (3B/7B/sharp, GGUF/fp8/fp16).
