Opus Clip finds moments; CapCut finishes them. Opus takes a long video and proposes clips with captions and a virality score, which is genuinely useful when you have a back catalogue to mine and no time to watch it again.
CapCut is the better tool in the general case: it is free, it is fast, its caption styles are the ones the algorithm is used to, and you are not fighting an AI editor for control of the cut. Use Opus for discovery on long archives, CapCut for anything you care about.
