SmoothyApp’s Multicam tool analyzes separate microphone tracks and chooses camera coverage from speaker activity. The output is a rough cut for you to review. It does not recognize every editorial moment or produce a guaranteed percentage of correct cuts.
Prepare synchronized source tracks
Put your synchronized camera footage and microphone recordings into a Premiere sequence. Keep each speaker’s microphone on its own audio track. Check sync near the start and the end of the recording; camera and recorder clocks can drift over a long take.
This workflow uses the source tracks exposed to the desktop app. Do not assume that any nested multicamera clip will reveal the separate cameras and microphones in the same way. Verify that the app lists the expected source tracks before running it.
If you have only a mixed microphone track, this tool cannot map the individual microphones to cameras. Other types of speaker recognition exist, but they are not this app’s separate-track workflow.
Connect and map the cameras
Follow the Premiere setup guide. In SmoothyApp, open Multicam and check that it has read the intended sequence.
Enable the camera tracks you want included, assign distinct camera numbers and map each selected speaker’s microphone to the corresponding enabled camera. For a two-person interview, that might mean the host microphone maps to the host camera and the guest microphone maps to the guest camera.
Listen to the microphone tracks individually. Heavy bleed from another speaker can make the activity-based switching less reliable. Muted, disabled or incorrectly mapped tracks need fixing before the analysis.
Set the cut rules
Minimum cut duration limits rapid switching. A few seconds can be a useful starting point for conversational material, but tune it for the recording rather than treating it as a rule.
The app also exposes hold time and a J-cut offset. Review how these choices affect the relationship between audio and picture. If you have an enabled wide camera, you can use the wide-shot option for overlapping speech. A wide shot does not replace decisions about reaction shots or B-roll.
Run the rough cut
The tool creates a new sequence from source media. Existing effects and titles are not copied into that sequence. Run it before finishing, and save the original project so you can compare the result or return to the source.
Processing time depends on the duration, track count and hardware. Avoid planning a delivery around an assumed two-minute runtime for every episode.
Make the editorial pass
Review the switches with the original audio:
- Overlapping speakers may call for a wide shot or a deliberate choice of focus.
- A listener’s reaction can be more useful than the active speaker’s camera.
- Short interjections do not always need a new angle.
- Noisy or uneven microphones can cause distracting switches.
- B-roll can cover a cut that is correct for speech but awkward visually.
