If you already record long videos (webinars, demos, tutorials, podcasts), you’re sitting on weeks of short-form content. This guide shows a fast, repeatable workflow: batch-slice in Opus Clip to find the best moments, then polish in CapCut so each clip feels native to Reels, TikTok, and Shorts. The goal is speed without sacrificing brand polish. Once your clips are ready, see CapCut vs Opus Clip (2025) for when to use each.

Quick answer (TL;DR)

  • Workflow: Opus Clip (auto-detect hooks + batch clips) → CapCut (captions, trims, brand style) → export 1080×1920 → schedule.

  • Throughput: From a 30-minute source, expect 8 publishable shorts (30–60s each).

  • Time budget: ~45 minutes total

    • 15 min in Opus (ingest → generate → pick top clips)

    • 25 min in CapCut (auto-captions, trims, overlays, music)

    • 5 min export + queue

  • When to use this: You want volume + consistency from one recording session (product demos, “how-to” lessons, founder updates).

(If captions and hooks are a bottleneck, see Best AI Writing Tools for Entrepreneurs (2025) for caption draft helpers.)

Who this is for

  • Solo creators and small teams who need daily/near-daily posts without filming every day.

  • Etsy/shop owners who batch record making/packing/process videos and want fast, on-brand clips.

  • Coaches/educators with webinars or Zoom recordings they can mine for bite-size insights.

What you’ll need

  • Source video (30 minutes) with clear audio (webcam or phone is fine).

  • Opus Clip for auto-slicing and hook detection.

  • CapCut (desktop or mobile) for captions, trims, overlays, and export presets.

  • Scheduler (Later/Metricool/Buffer) to queue across Reels, TikTok, Shorts.

  • Brand bits: logo (PNG), two fonts, two colors, a simple lower-third template.

Expected outputs

  • 8 vertical shorts (1080×1920), each with:

    • On-screen captions (high contrast),

    • A clear hook in the first 2–3 seconds,

    • Your brand style (font/color/lower-third),

    • A single CTA (e.g., “See the full demo” or “Shop the collection”).

Step-by-step: from a 30-minute video to 8 shorts

Troubleshooting (fast fixes)

Noisy or hollow audio

  • Run a quick noise reduction pass (high-pass at ~80–100 Hz, light NR).

  • Record closer to the mic; add soft furnishings to the room.

Too many filler words / dead air

  • In CapCut, use Smart Cut/filler-word trimming.

  • Tighten gaps to ~150–250 ms between lines.

Captions cover UI or crop off-screen

  • Keep captions 10–14% above the bottom edge.

  • Limit to 2–3 lines; add a shadow/box for contrast.

Clips feel jumpy

  • Add a subtle 2–3% zoom on alternate cuts or a 4–6-frame cross dissolve.

  • Trim breaths and half-words at cut points.

Wrong aspect ratio / black bars

  • Project and export at 1080×1920 (9:16).

  • Reframe with “Auto Reframe” or manual keyframes if needed.

File size too large

  • H.264, 8–12 Mbps VBR; AAC 128–192 kbps.

  • Avoid stacking heavy effects; they inflate bitrate.

Music drowns speech

  • Set music around −18 to −24 dB; enable auto-ducking.

  • Keep voice at or near 0 dB with a light limiter.

Flat lighting / weird color

  • Add a small contrast bump (+5–8), warm white balance slightly.

  • Use a key light at ~45°; avoid mixed color temps.

Hooks feel weak

  • Start with the outcome, mistake, or number: “The fastest way to ___…”, “Most people miss this ___…”.

  • Cut the first 2–4 seconds of throat-clearing.

Posting cadence slips

  • Batch once/week: 30-min source → 8 shorts → schedule 1–2/day.

  • Reuse your CapCut template (captions + lower-third) to cut edit time.
