What it does

Two OpenMontage tools that make the classic talking-head edit without a model: tools/video/silence_cutter.py finds pauses with ffmpeg silencedetect and removes them, speeds them up or only marks them; tools/video/auto_reframe.py turns a 16:9 interview into 9:16 by tracking the speaker's face with MediaPipe/OpenCV and smoothing the crop so it never jitters. Use them from inside OpenMontage or copy the scripts.

Use when

• Automatic jump cuts from silencedetect, plus a face-tracked 16
