Manual clip assembly after Opus picks the wrong 30 seconds

Opus is useful for finding candidate moments, but it will sometimes pick the wrong 30 seconds—or pick one good moment when the story needs three.

That is where browser-based assembly and CapCut desktop solve different problems:

• CapCut desktop wins when I need a full timeline, layers, effects, keyframes, and detailed audio work.
• A browser workflow wins when I already have the clips and want to trim, reorder, crop to 9:16, preview, and export one clean vertical compilation without installing a desktop editor.

My practical fallback after an Opus miss is simple:

1. Keep the source clips, not just the suggested highlight.
2. Mark the usable in/out points myself.
3. Put the clips in a deliberate order: hook, context, payoff.
4. Preview the vertical crop before exporting.

This is clip assembly, not AI video generation. The editor should make the choices visible and reversible.

I’m building ReelWorkshop, so this is a maker recommendation: the free demo lets you try the browser assembly flow. It’s free to edit and preview; Starter is $19.99/month if you need the paid tier. No auto-highlight promise—just a faster path from footage you already have to a finished reel.
