SponsorCut

Remove sponsor segments from local video and audio files using SponsorBlock.
New in version 1.0.3
SponsorCut 1.0.3

Changelog / Release notes:

- Architecture hardening: TranscodePolicy refactor
- Implemented a single decision graph for copy/transcode decisions.
- Introduced `CoreDecisions` with FINAL canonical booleans `canCopyVideo` and `canCopyAudio` computed once by `deriveCoreDecisions()`.
- Removed duplicated decision derivations; SW and HW/FAST paths now consume the same precomputed decisions.
- Renamed `deriveCorDecisions` -> `deriveCoreDecisions` for clarity and maintainabil
SponsorCut removes sponsor segments, intros, outros, and other non-content sections from locally stored video and audio files. It uses SponsorBlock community data to identify segments, then re-encodes or stream-copies the file with those sections cleanly cut out.

How it works:

Enter a YouTube or video ID, or share a file directly from your file manager or browser. SponsorCut fetches the SponsorBlock segment list for the ID, shows you what will be cut and how much time you'll save, then processes the file entirely on-device. The result is saved to your Downloads or Music folder.

Usage methods:
- Share a video or audio file from any file manager
- Share a URL from YouTube — SponsorCut extracts the ID and pre-fetches segments
- Enter a YouTube video ID manually and browse to the local file
- Open a file directly via a compatible player or browser

Features:
- Supports MP4, MKV, WebM, TS, M4A, MP3, AAC, and Opus files
- Audio-only files are saved to Music/SponsorCut with correct MIME type
- Cancel button stops processing at any time
- Wake lock keeps CPU active when the screen turns off during long jobs
- Diagnostic log shows detailed FFmpeg output after each run
- Status text is selectable for easy copying
- Remembers the last used video ID and file across sessions

All processing is local. No data is sent to any server except the SponsorBlock API query (video ID only) and an optional YouTube oEmbed title lookup. No analytics, no tracking, no accounts.

Requires Android 8.0 (Oreo) or later.

SponsorCut is free, open-source, and built in spare time. If it saves you time every day, consider buying the developer a coffee:
