The workspace at www-flux3.com generates 5–20 second AI videos with native audio from text or a starting image, routing across FLUX 3, MiniMax H3, Seedance, Wan 3.0 and Kling 3.0 Pro, at 720p or 1080p with video extension.
- Native audio removes the sourcing-and-syncing step that makes silent clips feel unfinished
- Five model families in one interface makes genuine comparison practical
- Draft and Enhance is the correct workflow and saves real money on iteration
- Video extension is a sensible answer to the coherence ceiling
- Generation quality is inherited from third-party models, not built here
- Model availability and terms are set upstream and can change without notice
- Twenty seconds is a hard ceiling; extensions accumulate visible drift
iZotope RX
iZotope RX 12 is an audio repair and post-production suite with more than 50 tools for restoration, dialogue rescue and sound design. Neural-network modules including Dialogue Isolate, Music Rebalance and Repair Assistant sit alongside three decades of conventional spectral repair.
- Solves problems with no alternative solution when a take cannot be re-recorded
- Named modules for named faults, rather than one general cleaner applied to everything
- Neural source separation does something categorically different from filtering
- Ambience Match is the detail that makes repairs invisible rather than merely clean
- A real learning curve — the value is in knowing which module matches which fault
- Every process trades artefacts against the original problem, and overprocessing is easy
- Separation quality varies enormously with material, and nothing warns you in advance
