Features

• Compress — Drag-and-drop or file picker; quality slider and estimated target size
• Multi-select — Pick several files or a folder; batch queue with combined size summary
• Empty start — No seeded demo jobs; active processes and history are empty until you add real files
• FFmpeg — H.264 via libx264 (CPU) or NVIDIA NVENC when enabled in settings and available in your FFmpeg build
• Output modes — Default same folder as source (*_klein.mp4) or a fixed output folder (Documents\HorosCompress\Output by default)
• Replace original — Optional setting to overwrite the source after a successful encode (via temp file)
• Active jobs — Progress, status, queue, cancel; pause holds the progress display (encode continues)
• History — Completed jobs with savings and paths (in-session; persistence planned)
• Settings — Export mode, replace original, default quality, GPU toggle, placeholders for language/theme/notifications
• starter.bat — One-click Windows bootstrap (.NET 8 + FFmpeg via winget, then dotnet run)

UI mockups and reference screens live under mockups/app-v2/ (see screenshots below).

Requirements

• Windows (primary target)
• .NET 8 SDK
• FFmpeg on PATH (or use the starter script to install via winget)

Quick start

Windows (recommended): from the repo root, run:

starter.bat

starter.bat calls scripts/bootstrap.ps1, which checks for .NET 8 and FFmpeg, installs them with winget when missing, then runs the desktop app in Release.

Check dependencies only (no app start):

powershell -ExecutionPolicy Bypass -File scripts/bootstrap.ps1 -CheckOnly

Manual:

git clone https://github.com/HorosCodeOriginal/HorosCompress.git
cd HorosCompress
dotnet run --project HorosUpscaling.Desktop -c Release

Encoded files are written according to your settings (same folder as source or your fixed folder). The repo Output/ directory is git-ignored except for .gitkeep (local dev convenience).

Build

dotnet build HorosUpscaling.sln -c Release
dotnet build HorosUpscaling.sln -c Debug

CI runs on GitHub Actions (Windows, .NET 8) — see .github/workflows/dotnet.yml.

Known limitations (honest scope)

Area	Current behavior
Pause	Toggles UI progress only; FFmpeg keeps encoding
Language / theme buttons	Stored in settings; full UI switch not yet wired
Notifications	Setting stored; no OS notifications yet
History	Session memory only (no disk persistence yet)
GPU	NVENC when available; otherwise libx264
