The problem with your online course video
Course creators record dozens of lessons and need consistent, tight pacing.
By hand, finding and cutting every gap often takes longer than the recording itself.
The fast method
Import your online course video, pick a cut style (Natural, Balanced, Punchy) and run the analysis.
You see the number of cuts and the new duration, listen, then export a ready-to-publish file.
Settings that matter
Sensitivity decides what counts as "silent", minimum pause avoids micro-cuts, and padding protects the start and end of sentences.
Keep the silences that help — good editing still breathes.
Why Cutting-Silence
100% local processing on Mac (nothing uploaded), 5 free exports with no card, then a lifetime license.
Perfect as a first pass before your usual editor.
