Muxiveo

Muxiveo is an all-in-one open-source desktop suite for preparing, remuxing, encoding, and synchronizing video and audio in MKV and MP4 containers. It unifies complex media workflows that typically require juggling multiple separate applications (remuxers, audio waveform editors, transcoders, metadata injectors, and AI scripts) into a single, cohesive interface.

Whether you need a 3-second lossless remux, automated multi-source audio alignment, or full GPU-accelerated transcoding with Dolby Vision injection, Muxiveo handles each task individually or runs the entire pipeline in a single click.

Key Features :

• Lossless Remuxing & Container Preparation:

• Universal drag-and-drop support for MKV, MP4, MOV, TS, external audio, and subtitles.

• Reorder tracks, assign BCP47 language tags, and configure Matroska flags (Default, Forced, Hearing Impaired, Commentary).

• Native Matroska engine with automated cleanup of legacy EIA-608/708 closed captions.

• Quick right-click extraction of any audio or subtitle stream.

• Acoustic Audio Synchronization (Hybrid Studio):

• Automatically detects and aligns audio delay between different releases/editions using FFT-based acoustic cross-correlation.

• Eliminates the need to export audio into waveform editors to calculate offsets manually.

• Dolby Vision & HDR Studio:

• Transfer, inject, inspect, and reconstruct Dolby Vision (Profile 5, 7, 8) and HDR10+ dynamic metadata without re-encoding video.

• Full inspection and correction of HDR mastering metadata (MaxCLL, MaxFALL, color primaries, transfer characteristics).

• GPU & CPU Video Encoding:

• Hardware acceleration via NVIDIA NVENC (with NVEncC support), Intel QSV, AMD AMF, and Linux VAAPI.

• Software reference encoders: libx264, libx265, and libsvtav1 (AV1) with automated 2-pass target size budgeting.

• Advanced audio handling: TrueHD Atmos and DTS:X passthrough, multi-channel transcoding to E-AC-3, AAC, or FLAC, and automatic downmix/compatibility track generation.

• AI Frame Interpolation (MVO-RIFE Extension):

• Boost motion fluidity (e.g. 24 fps to 60 fps) directly on your GPU using neural network frame interpolation.

• Batch Automation & CLI:

• Decision profiles to automate track selection and encoding rules across entire TV seasons or video libraries.

• Headless command-line interface (CLI) for headless servers, scripts, and automated batch processing.

Muxiveo is 100% free and open source (GPL-3.0), ad-free, telemetry-free, and operates entirely offline. Standalone packages are available for Linux (AppImage), Windows (installer and portable), and macOS.
