Why this lesson: the trap here is polish. You'll be tempted to spend two hours perfecting one Reel — and then never post again. This lesson gives you the minimum edit that makes a raw clip watchable, in one free tool, in ten minutes. Done beats polished, every time.
First, recall
From Lesson 4: a Reel lives or dies on its first second, and rewatches (watched past 100%) are a top quality signal. Editing exists to serve exactly those two things — a hook on frame one, and no dead air that makes anyone swipe.
The minimum viable edit — four moves
Open your raw screen clip and voiceover in one free tool (CapCut is the easy pick — free, phone or desktop). Then do only these:
Big on-screen text — a bold hook line on frame one, and short captions for the key beats. This is what sells the first second.
Trim dead space — cut the pauses, the "um", the moment before the code runs. Every dead second is a swipe.
Keep cuts fast — jump straight from problem to result. Tight pacing is what drives the rewatch.
Auto-captions — one tap generates subtitles from your voiceover. Most people watch on mute; captions are non-negotiable.
The rule that keeps you shippingDone beats polished. A watchable Reel posted today teaches you more than a perfect one posted "eventually". Cap yourself at the four moves above and hit publish — the feed, not your timeline, tells you what's actually good.
Worked example · cutting the bug-fix clip into a Reel
Raw material: your 15s screen capture + one-line voiceover from Lesson 12 (the React state re-render bug).
Frame 1 text: big — "Your React state isn't re-rendering. Here's why." Over the broken code.
Trim: drop the 2s of you hovering before the fix. Snap from wrong result straight to the corrected array.
Captions: auto-generate from the voiceover, bump the size, done.
Ten minutes, one tool, no face. From "bug I fixed at work" to a posted Reel in a single sitting.

1. Why are auto-captions treated as non-negotiable on a Reel?
A huge share of Reel viewing happens on mute. Captions carry your voiceover to those viewers — skip them and half your audience gets nothing.
2. Trimming dead space and keeping cuts fast mainly serves which signal?
Tight pacing with no dead air keeps people watching to the end — and past it. That rewatch / watch-time signal is what the feed pushes hardest.
3. The guiding rule of this lesson is…
Done beats polished. Four moves, ten minutes, publish. The feed teaches you more than another hour of tweaking ever will.
Your turn · do this now
Import your raw bug-fix clip and voiceover into CapCut. Do the four moves only — hook text, trim, fast cuts, auto-captions — and stop. Set a 15-minute timer if you have to. Send me the export and I'll flag anything that's dead space or a weak first second.
