AI Video Ads
You've seen Opus Clip's ads everywhere — "turn one long video into ten viral shorts". And the app holds up its half: long video in, ranked short clips out, great for podcasters and streamers repurposing long content. But the half that decides whether YOUR video makes money — will anyone stop scrolling for it? — doesn't live inside any AI clipping tool. It's measurable, before you spend a dollar.
When your original beats every re-cut, we say exactly that — the point is the answer, not selling you edits. It takes about 10 minutes, and your first tournament is free.
Generating and editing video is the easy half now. The hard half is knowing which version deserves your ad budget. PreTestAds runs your video through a tournament: we cut it 6 ways, score every cut — and your original — with a brain model trained on fMRI data, benchmarked against 76 proven viral TikTok ads, and hand you the winner with receipts. Your first tournament is free.
Templates, captions, and effects raise the floor — they don't pick the hook. In our benchmark of 76 top TikTok ads, the difference between winners and losers shows up in the first 3 seconds of the attention curve, long before production quality matters. That's why two videos from the same AI clipping tool can have a 40-point score gap. See how the winners hold attention in the benchmark library — every curve is public.
This isn't theory — we run real ads from the Meta Ad Library through the same brain model. In our Facebook ad library, live ads from active advertisers scored anywhere from 22 to 100 — ads that looked equally polished. Production quality didn't separate them; the first seconds did. You can spy-score any advertiser's live ads yourself through the PreTestAds MCP before you borrow their angle.
The tool is rarely the problem — but if you're comparing: Opus Clip alternatives, compared honestly →
They can — the tool doesn't decide the outcome, the first seconds of the video do. A AI clipping tool determines how the video looks; whether it holds attention against proven winners is measurable before you spend, with a brain-model score benchmarked against 76 top TikTok ads.
Export the finished video and run it through an ad pre-test. PreTestAds scores it 0-100 against 76 TikTok Creator Academy winners, shows the second-by-second attention curve, and — in tournament mode — auto-cuts 6 alternate versions and tells you which cut wins. First tournament is free.
Polish and performance are different axes. Templates and effects make a video watchable; conversions come from the hook holding attention in the first 3 seconds. Scoring the video before spending shows exactly where attention drops, and a tournament tests whether a tighter cut fixes it.
