AI Creative Testing
Runway is where AI generation meets an actual edit suite — generate a shot, extend it, restyle footage you already have, cut it together without leaving the tool. For ad teams it's less a slot machine and more a workshop. Which makes testing the finished cut even more valuable.
Runway's difference is control: motion brush to choreograph movement, camera controls, video-to-video restyling of real footage, shot extension, inpainting. Ad teams use it to finish creative, not just conjure it — an existing product clip becomes five stylistic variants, a good take gets extended past its awkward ending, a UGC clip gets cleaned up without losing its authentic feel. The output is a deliberate cut, which means when it underperforms, someone made a fixable decision somewhere.
Edited AI ads fail differently than raw generations: not with obvious weirdness but with polished stretches that quietly don't earn their runtime. The restyle looks so good you keep four seconds of it; the extended shot buys length the story didn't need; the graded intro delays the product because it's beautiful. Each choice is defensible in the timeline and collectively fatal in the feed. An attention score is the outside opinion the edit bay lacks — it has no attachment to the hours you spent on that shot.
Upload the finished Runway cut to PreTestAds for a percentile score against 76 top TikTok performers, plus the second-by-second curve. Because you're in an editor, the fixes are surgical: trim the stretch where attention sags, move the product beat ahead of the drop-off second, swap the opening shot for the peak-moment frame the report identifies. Re-render, re-score. It's the same generate-score-regenerate loop, except your regeneration tool is a timeline — which makes each iteration even more precise.
Runway's video-to-video restyling enables a test most teams never think to run: the identical cut in different visual treatments — clean, gritty, animated, desaturated. Same structure, same timing, different skin. Scoring the set isolates how much visual style alone moves attention for your audience, and the answer feeds every future creative decision you make. It's a full creative test for the cost of a few renders and credits.

Test Your Runway AdsYes. Upload the finished cut to PreTestAds and an fMRI-trained model predicts second-by-second viewer attention, benchmarked against 76 top-performing TikTok ads. You get a 0-100 percentile score, hook strength, and drop-off timing before spending.
Edited cuts fail subtly — polished stretches that don't earn their runtime rather than obvious glitches. The attention curve flags the exact seconds that sag, and because you're in an editor, the fix is a precise trim or re-order instead of a full regeneration.
Rendering the identical cut in several visual treatments with Runway's video-to-video, then scoring each. Because structure and timing stay constant, the score differences isolate the effect of visual style on attention — knowledge that transfers to all your future creative.
