Professional NLE Video Editor & Post-Production Playbook
Use this skill whenever editing real footage, cutting talking-head interviews, mixing multi-track audio, adding word-synced captions, color grading, or assembling a master edit in HyperFrames or Remotion.
1. The NLE Multi-Track Architecture
| Track Index | Role | Engineering Rule |
|---|---|---|
| Track 0 (A-Roll Plate) | Primary talking-head or base video clip | Never cut visually without motivation; use J-cuts/L-cuts so audio leads or trails video by 0.15s–0.4s. |
| Track 1 (B-Roll / Screen / 3D Cutaways) | Full-frame or split-screen visual proof | Enter on spoken keyword timestamp; use cut-the-curve or whip-pan seam, never a slow muddy dissolve. |
| Track 2 (Scrim & Contrast Grade) | Footage-independent contrast protection | Dynamic bottom gradient or radial scrim (rgba(7,11,18,0.68)) timed with text overlays so typography is 100% legible over bright footage. |
| Track 3 (Graphic Overlays & Lower-Thirds) | Lower-thirds, metric cards, callout HUDs | Follow talking-head-recut rules: enter on exact transcript word start, exit cleanly before next topic. |
| Track 4 (Captions Rail & Peak Embeds) | captions-overlay Drop / Rail / Embed |
Rail rides bottom ~6-8% on true-centered canvas; scarce embed climax words composite behind the subject matte. |
| Audio Bus | Voiceover + BGM + Intentional SFX | Normalize VO to -16 LUFS; duck BGM by -12 dB to -15 dB during speech with 0.25s attack and 0.6s release; place SFX (whoosh, click, riser, sub-hit) on exact visual ignition frames. |
