How to make behind-the-scenes clips for Shorts, Reels and TikTok

Updated 3 platforms5 steps

Short answer

Show how a product / event / episode was actually made, in a short-form clip that builds trust and curiosity. Deliver 9:16 on YouTube Shorts, Instagram Reels and TikTok. Burn captions in on every platform.

Start from: vertical phone camera, behind-the-camera selfie angles and process B-roll.

The steps

  1. Capture B-roll: Shoot 2-3 minutes of process clips on phone; favour motion, not talking head.
  2. Pick 3-5 strongest moments: Filter to moments that change or reveal something. (Highlight detector)
  3. Crop 16:9 to 9:16: Subject-tracking reframe so the action stays in the safe-zone. (Landscape to Vertical)
  4. Burn captions: Use lower-thirds, not full-width - let the action breathe. (Burn-in)
  5. Export pack: 9:16 short + 1:1 carousel for the same source. (Content Pack)

What to produce: Vertical 30s B-roll highlight (9:16, 30 s); Process carousel (5-8 slides) (1:1).

Pitfalls to avoid

  • Talking-head intro makes the clip feel like every other channel
  • Music bed that masks the real audio of the process
