SmoothyApp is the free desktop app for Apple Silicon Macs and Windows x64. It bundles six tools that process media on your computer: multicam, silence removal, Audio Cleanup, captions, video compression and Assets. Studio is the optional cloud service for transcript analysis and AI generation.
An earlier version of this guide described a planned “SmoothyDesktop” with a full local AI toolkit. SmoothyApp now covers the local tools below and works with both Premiere Pro and DaVinci Resolve Free. Resolve uses a local Scripts connector rather than the earlier bridge.
The six local tools
- Multicam analyzes separate microphone tracks and creates a camera-switching rough cut. Each speaker needs a microphone-to-camera mapping.
- Silence Removal detects quiet sections using a volume threshold, minimum silence duration and padding around speech.
- Audio Cleanup splits a recording into exact speech and music tracks, with noise kept in the music, or enhances the speech and removes everything else with local models.
- Captions uses Whisper on your machine. Choose a Premiere sequence, a Resolve timeline or an audio/video file, correct the text and timing, then save an SRT.
- Compressor creates HEVC MP4 copies. It checks for supported hardware encoders and has a software fallback.
- Assets converts supported images and SVGs to PNGs. SVG output starts at 1000 pixels wide with proportional height, and you can change the size.
These tools do not require a Studio subscription. Caption engines, image models and the Audio Cleanup engine and models may need an initial download before offline processing works. Processing speed depends on the media, model and hardware; there is no universal completion-time guarantee.
What connects to Premiere Pro or Resolve?
The app installs a bundled CEP panel for Premiere Pro. Open it in Premiere, keep SmoothyApp running and follow the connection guide. The local bridge lets the desktop app read sequence information and send supported edits, captions and PNG assets back to Premiere.
For DaVinci Resolve Free, install the Resolve helpers once and start Workspace → Scripts → Smoothy Connector each Resolve session. The connector sends multicam and silence-removal timelines, captions, media and markers. Read the Smoothy Connector guide.
Multicam and default Silence Removal create new sequences in Premiere or new timelines in Resolve from source media. They do not copy existing effects and titles. Premiere’s Silence Removal also offers in-place ripple deletion, which changes the current sequence and creates separate undo steps. Start with a saved project and review the result before continuing.
What still uses the cloud?
Studio provides Shorts discovery, hooks, titles, descriptions and the additional Pro toolkit. These requests send the relevant input to cloud services. They are not local Whisper features, even when you start them from the desktop app.
The desktop Shorts workspace supports multiple source types and candidate-history review. Its editor action adds markers to a connected Premiere Pro sequence or DaVinci Resolve timeline to help you locate suggested ranges. It does not export a finished Short or build a vertical sequence automatically.
Local media processing and optional anonymous usage telemetry are different things. The app’s privacy policy describes account data and telemetry; local processing means the media itself stays on the computer for those six tools.
Can I use it with DaVinci Resolve?
Yes, including DaVinci Resolve Free. SmoothyApp supports multicam, silence removal, captions, media imports and Shorts markers through its local Scripts connector. Install the Resolve helpers once, then start Workspace → Scripts → Smoothy Connector each Resolve session. Follow the Smoothy Connector guide or explore DaVinci Resolve support.
Choose the smallest useful workflow
For subtitles, start with local captions. For graphics, use the SVG importer. For a podcast, prepare separate speaker recordings before running multicam. Add Studio when transcript-based planning helps the task; it is optional for the local tools.
