faces = detect + track faces. reframe = the same, plus normalized crop keyframes for a target aspect ratio (editplan-ready). asd = active-speaker detection (mouth motion x audio envelope, no torch needed): per-track speech scores + speaking segments; pass target_aspect to also get crop keyframes that follow whoever is speaking. diarize = visual diarization: the same ASD pass, returned as speaker turns (spk_) with speaker_count/coverage/degraded — use it when audio diarization returns 0 speakers. capabilities = return supported ops/features without running any work (no source needed).
