Trimlet v0.3.0 Early Access 1

Trimlet v0.3.0 Early Access 1

This source-only prerelease adds the first usable native Windows implementation while keeping the existing macOS PoC and shared contracts in one repository.

Windows Early Access

• Native C#/WinUI 3 application for Windows 10 build 17763 and later
• Open dialog, drag and drop, direct preview, seek, playback, and keyboard navigation
• One- and ten-frame movement plus five-second jumps
• IN/OUT selection, range preview, and selected-duration display
• ffprobe inspection, keyframe candidate analysis, and audio-stream selection
• Fast stream-copy and Accurate H.264/AAC export plans
• Encoder usability probing, progress, cancellation, redacted diagnostics, temporary-output validation, and safe finalization
• English and Japanese resources
• Unit, shared-contract, and generated-media integration checks

Interface and documentation

• Reduced permanent explanatory copy in the Windows work surface
• Added shared product/interface principles in docs/PRODUCT_DESIGN.md
• Added Windows human-check and maintainer documentation
• Added a Windows-to-macOS owner handover with parity gaps and review candidates

What Early Access means

The core open → select IN/OUT → export workflow is available and suitable for evaluation. This is not a supported binary distribution or a claim of complete macOS parity.

Known gaps:

• no automatic Windows preview proxy when native playback cannot decode the source;
• nominal-frame-rate rather than source-PTS frame movement for variable-frame-rate media;
• no installer, MSIX, code signature, or prebuilt executable;
• M2TS/MTS preview depends on codecs installed in Windows;
• broader real-machine and large-media coverage remains pending.

Build and run

Install .NET SDK 10.0.400 plus separate ffmpeg and ffprobe, then run from PowerShell:

.\apps\windows\run-human-check.ps1

The repository and release do not contain FFmpeg, ffprobe, test videos, generated application bundles, or developer-machine caches.

Trimlet v0.2.1 PoC

Trimlet macOS proof-of-concept maintenance release.

Highlights:

• Fix macOS CI compatibility with Swift 6.1
• Add English and Japanese project and donation guides
• Document an optional, non-gating donation model inspired by MangaCrisp
• Add the Windows native implementation handover
• Keep shared contracts ready for macOS and Windows development

This is a source-only prerelease. FFmpeg binaries and sample media are not bundled. See the repository documentation for installation, licensing, third-party notices, and current limitations.

Trimlet v0.2.0 PoC

Trimlet v0.2.0 PoC

This is the first public source-only proof-of-concept release of Trimlet.

Included

• Native Apple silicon macOS application source
• SwiftUI/AVFoundation playback and trimming interface
• One- and ten-frame movement plus five-second jumps
• IN/OUT range selection
• Fast keyframe-aware export planning
• Accurate VideoToolbox H.264 export path
• FFmpeg progress, cancellation, and post-export validation
• Shared contracts and a Windows implementation handoff

Important limitations

• No prebuilt application, DMG, FFmpeg, ffprobe, or test media is attached.
• Building requires a compatible Swift toolchain on an Apple silicon Mac.
• Runtime export currently expects separately installed FFmpeg and ffprobe.
