SmoothyApp is a free desktop toolkit that connects to Premiere Pro through its bundled SmoothyEdit panel. The local tools work without a Smoothy account. Studio adds optional cloud analysis and timeline markers when you sign in.
The SmoothyApp page now previews version 1.5, including editable captions, a collapsible sidebar and the new SVG importer. Download buttons continue to serve the latest published build until 1.5 is released.
Install and connect the panel
- Download the desktop app. Choose macOS or Windows on the SmoothyApp download page, then install it.
- Start SmoothyApp. It runs beside Premiere and manages the local editing tools.
- Restart Premiere Pro. If Premiere was open during installation, close and reopen it so it can load the bundled panel.
- Open the panel. Go to Window → Extensions → SmoothyEdit in Premiere Pro.
- Open your project and sequence. Check the Premiere connection status in SmoothyApp, then refresh the sequence in the tool you want to use.
The bundled panel connects to the desktop app locally. Keep both the app and panel open while sending results to Premiere.
Choose a local tool
Multicam maps microphone tracks to camera tracks and cuts between speakers. Review the camera mapping before generating the edit. In the 1.5 preview, mappings are remembered for later use.
Silence Removal finds quiet sections with your selected microphone, threshold, minimum silence duration and padding. The default workflow creates a new sequence. In-place editing performs ripple deletion on the current sequence when you select that option.
New sequences generated by multicam and default silence removal do not copy existing effects and titles. Review the result and apply finishing work afterwards.
Captions uses Whisper locally to transcribe a sequence or an audio/video file. Export an SRT or send captions to Premiere. Version 1.5 adds cue text and timing edits, transcript-wide find and replace, and local reformatting.
Compressor creates smaller video files locally using HEVC, with quality and speed controls. Hardware acceleration is used when available. Compressed copies go to a separate folder.
Assets & SVG importer is new in the 1.5 preview. Load a graphic, set its size and background, then export a PNG or send the selected image to your active sequence. SVGs are converted to PNG stills before import. Follow the SVG import guide for the full walkthrough.
Connect optional Studio tools
Sign in to your Smoothy account in the desktop app to use Studio. The desktop app connects to the website through the online relay so cloud results can reach Premiere. This is separate from the local connection between the bundled panel and the desktop app.
Studio analysis uses credits and sends the input needed for that cloud operation. Local multicam, silence removal, captions, compression and Assets processing stay on your machine.
In the 1.5 Shorts workspace, choose a Premiere sequence, transcript, media file or YouTube transcript. Pick Multiple shorts or Best part, review the results, then use Add markers in Premiere. Markers help you locate the suggested moments; you still review and make the edit.
If Premiere does not connect
Check that the desktop app is running, the SmoothyEdit panel is open, and a project is loaded in Premiere. After installing an update, restart Premiere and reopen the panel so it uses the updated bridge. Refresh your active sequence before running a tool.
