Why it matters
More than stems—we reset how long-form AV gets made
Long-form processing should not mean crashes, mushy audio, or endless manual steps. Most tools still ship rough algorithms and brittle pipelines. MediCut is built as an all-in-one Video & AI Music workspace—not only edit-in-the-box like a pure clipper, but full audio lanes, stem extraction, and intelligent composition: 13.5-hour sessions stay stable with headroom beyond that, SaaS and multi-seat workflows, and separation quality that hits demucs-class targets. Beyond clean stems across video and audio, you get sound design, custom voice modification, AI voice swap, and AI-assisted music—one chain for many industries, with unmatched efficiency and professional-grade quality.
Core capabilities
Full coverage for real production workloads
One-click extract
AAC, MP3, WAV, FLAC, M4A, MP4, MOV, MKV, and more—AI-driven extract with minimal hand-holding, including 13.5h+ timelines at peak efficiency.
Vocal & backing stems
Aurol-class model tuned in-house—demucs-level targets for atomically precise separation of pure vocals and faithful backing tracks, still solid on 13.5h material.
7-stem pro split
Drums, bass, other, vocals, guitar, piano, and additional instruments—demucs-aligned quality for edit, mix, and post, including long-form.
Beyond stems
Stem-grade separation plus custom sound layers, playful or serious voice FX, AI voice swap, and AI music generation—entertainment to pro workflows.
Long-form engine
Purpose-built pipeline: 10 minutes to 13.5h+ without memory blowups, stutter, dropped frames, or quality collapse—AI model, lossless math, smart parsing.
Merge back to media
Replace tracks in place, Seamlessly replace original audio tracks in-place, export watermark-free up to 4K—no third-party glue for 13.5h+ projects, faster turnaround end to end.
Batch throughput
Batch upload, separate, and export for MCNs, houses, and schools—parallel 13.5h-class jobs with a big jump in wall-clock efficiency.
SaaS & enterprise
Cloud SaaS with multi-seat collaboration, roles, and security—plus custom modules, faster lanes, API hooks, and policy fit for large orgs.
Top-tier resampling
Custom Kaiser-sinc on millions of diverse clips—band-limited reconstruction, ~−80 dB stopband rejection, linear phase, crisp transients, demucs-class targets, proven on 13.5h+ files with zero external deps—quality first.
Pipeline breakthrough
Single-pass read, auto-resample, single write—no legacy multi-hop I/O or external resamplers that stack quantization drift. Eliminate repeated quantization, inconsistent algorithms at the source, often 50%+ faster exports, reproducible quality, one-click target rates, rock-solid on 13.5h+—finally both quality and speed.
Key advantages
Three pillars that set the bar
🎯 Long-form first
Among the few stacks that truly hold 13.5h+ separation—low memory, high speed, resilient runs, SaaS and team modes, with room beyond that ceiling.
🎯 Full chain
Stems plus sound design, voice FX, AI swap, and AI music—no extra toolchain to finish the story across industries.
🎯 Consistent grade
Studio-grade bar with Aurol-class models—demucs-level targets on shorts and 13.5h alike: clean vocals, intact backing, no harsh artifacts.
🎯 Anyone can ship
Upload → extract → split → extend → export in a handful of steps—SaaS multi-seat, 3-step feel on long jobs, often 10× faster than classic stacks, with QA on every output.
🎯 Hard to copy
Custom algorithms plus unified pipeline create a triple barrier—tuning rivals cannot clone, measurable listening gains, and commercial-grade quality you can stand behind.
Built for your lane
From solo creators to enterprise teams
🎬 Short video
Vocal-out backing, clean voice for captions, denoise for remix—plus FX, swap, and custom layers at demucs-class quality, even on long clips.
🎥 Film & pro edit
Kill bed, isolate dialog, full 7-stem control for mix, with sound-design layers—Aurol-class targets on 13.5h+ reels, less grunt work in post.
📹 Live & MCN
Pull host voice from replay audio, strip beds, remix with swap/FX—monetize 13.5h+ archives with demucs-class fidelity and longer-run headroom.
🎓 Online education
Boost instructors, kill room noise, sweeten with tailored beds—great on long lectures and unlimited-length upgrades when you need them.
💼 Corporate
Meeting stems for transcripts and archives—SaaS seats, org templates, demucs-class quality on 13.5h+ captures and long-meeting integrations.
🎵 Music & creators
7-stem pulls into AI music and custom layers—swap and FX for variety, pro feel on export with harmonics intact.
🎛️ Odd sample rates
Pain: weird rates (e.g. 41 kHz) that trash conversions or fail export. Here: auto-tolerant paths with Kaiser-sinc—lower loss than typical tools, stable on 13.5h+, less manual babysitting.
Measured audio quality
Numbers you can compare
| Dimension | Our Kaiser-sinc | Basic industry | Typical “good” stack |
|---|---|---|---|
| Passband flatness | < 0.5 dB attenuation | 10–15 dB HF loss | 3–5 dB loss |
| Stopband rejection | ~−80 dB class | < −20 dB | ~−40 dB |
| Phase | Strictly linear | Non-linear | Approx. linear |
| Listening | Transparent, natural | Harsh, detail loss | Thin vocals |
| Metric | MediCut | Typical tools | What changes |
|---|---|---|---|
| HF detail | < 0.5 dB loss | ~12 dB loss | Fuller, clearer top |
| Phase delay | < 0.1 ms | ~0.8 ms | Perfect AV synchronization |
| THD | 0.05% | 0.5% | Lossless separation of fine audio details |
