Opus Clip turns long videos into short, viral clips using AI. It's built for fast repurposing, mainly for TikTok, Reels, and Shorts.
About Opus Clip
If you’re a creator trying to pump out viral clips from long-form videos in minutes, Opus Clip feels like magic. Drop in a YouTube podcast, webinar, or talking-head video, and boom—it spits out a handful of short clips with snappy cuts and big captions, already framed for social. For speed demons and time-crunched creators, it’s a “drag and done” kind of tool that gets you clips without blinking.
But here’s where the magic wears off: you don’t get much say. You can’t pick the exact moment where your guest dropped that golden quote. You can’t finesse the captions or polish the pacing. Opus decides, not you. If you're an editor, an agency, or just someone who actually cares about tone and timing, this feels like handing your footage to a stranger and hoping for the best. So yeah—it’s fast. But is it your voice, your message, your brand?
