CrunchyGUI is a native macOS app for video conversion, remuxing, audio processing, subtitles, metadata editing, and batch encoding, powered by FFmpeg. Based on the current source and README, its features include:
Video encoding and formats
- MP4 and MKV output.
- Software encoding with SVT-AV1, H.264/x264, and H.265/x265.
- Apple VideoToolbox hardware encoding for H.264 and HEVC.
- Video stream copying for remuxing without re-encoding.
- Quality, speed presets, frame-rate adjustment, keyframe intervals, and hardware-specific controls.
- Codec-specific advanced arguments and a live effective-settings preview.
Color and picture adjustments
- Automatic detection of source color metadata, bit depth, and HDR/SDR.
- Preserve source color, convert HDR to SDR, or manually configure color handling.
- Six tone-mapping algorithms, including Hable, Reinhard, and Mobius.
- Interactive color analysis with frame previews and hue, saturation, brightness, contrast, and gamma adjustments.
- Compare source interpretations, step through nearby frames, and confirm or discard adjustments.
Cropping and resizing
- Automatic letterbox detection using fast distributed samples or thorough every-frame analysis.
- Manual crop overrides with visible edge measurements.
- Keep cropped source size, fix width or height, specify exact dimensions, or fit within bounds.
- Common resolution presets, aspect-ratio locking, optional upscaling, and sample-aspect-ratio correction.
- Bicubic, Lanczos, and Spline36 scaling.
Noise reduction and sharpening
- Up to four noise-reduction passes and four sharpening passes.
- HQDN3D, Wavelet, NLMeans, and BM3D denoising.
- CAS, LapSharp, and Unsharp sharpening.
- Individual filter presets and detailed customization for supported filters.
- Performance warnings for expensive filter combinations.
Audio
- Up to four independently configured output tracks, using embedded or external audio.
- Stream copy or conversion to AAC, AC-3, E-AC3, or Opus.
- Channel layouts from mono through 7.1, including Dolby Pro Logic II downmixing.
- Bitrate, sample-rate, track-title, and default-track controls.
- Streaming, film, and custom loudness normalization, including two-pass analysis and optional pre-scanning.
- Export and convert, or raw extract of audio files from source
Subtitles and chapters
- Embedded and external subtitle selection, language tags, default tracks, conversion, and burn-in.
- Automatic selection based on the Mac’s language.
- Selectable bitmap/PGS subtitles in MKV; burn-in for MP4.
- Import, edit, add, remove, restore, or generate chapters at regular intervals.
- Export and convert, or raw extract of subtitle files and chapters from source to common formats.
Metadata and artwork
- Source metadata import and online lookup through TMDB and TheTVDB.
- Editable titles, sorting, media kind, descriptions, genre, release date, ratings, studio, composer, and artwork.
- Poster importing, removal, and aspect-ratio cropping.
- Metadata-only saving to a new file or replacement of the original without re-encoding media.
- Validated native metadata updates for supported MP4-family files; stream-copy remuxing for MKV.
Batch processing and queues
- Reusable JSON templates and per-tab template settings.
- Batch import from selected files or folders, optionally including subfolders.
- Per-file source inspection and language/channel-based track matching.
- Queue reordering, saving, editing, pause/resume, cancellation, and cleanup.
- Historical jobs can be loaded as new jobs; import warnings remain accessible.
Workflow and monitoring
- Short sample encodes with configurable start time and duration.
- Progress, rolling FPS, elapsed time, and ETA.
- Saved PLIST projects and preferences.
- Automatic filename cleanup and collision numbering.
- Optional custom Finder thumbnails.
- FFmpeg selection, build inspection, thread overrides, contextual help, and optional debug logging.
- Metadata-service credentials stored in macOS Keychain.
FFmpeg and FFprobe must be installed separately, with support for the selected encoders and filters.
