AI Creative Testing
Veo generates video with sound — dialogue, ambience, effects — straight from a prompt, and it lives inside the same Google ecosystem as Gemini. That makes it the most loop-friendly generator of all. Here's how to close that loop with attention data.
Most video generators hand you silent footage; Veo generates the soundtrack too — spoken lines, ambient noise, effects synced to the action. For feed ads this matters more than it sounds: audio-on viewers convert differently, and a generated voice line can carry the hook while the visual carries the stop. A Veo generation is closer to a finished ad than any other model's raw output, which makes the temptation to just run it even stronger — and the case for scoring it first even better.
Here's the tightest creative loop available right now: score your ad in PreTestAds, paste the AI Report into Gemini (which can watch your video frame by frame), have it diagnose the failing moments, then have it rewrite the Veo prompt to fix them. Generate, re-score, repeat. Every tool in the triangle speaks to the next — the report is written to be pasted into a chatbot, Gemini reads video natively, and Veo takes structured prompts. Our Gemini workflow tutorial covers the coaching step in detail; Veo just adds the regeneration arm.
Veo's prompt adherence is strong, which means it renders what you asked for — including your mistakes. Scored Veo ads fail most often on pacing: a cinematic build the feed has no patience for, or a spoken hook that starts a beat too late. The attention curve makes this brutal and specific — you'll see the exact second the slow build loses the room, and whether anyone is still watching when the CTA lands. Fix the prompt, not the concept: front-load the reveal, start the voice line on frame one.
The same concept generated in Veo, Sora, and Kling will score differently — often dramatically. Tool choice is itself a testable variable. Generate your hero concept in two or three models, score the batch, and let the benchmark pick the production stack for that campaign. The percentile score is tool-agnostic: it only measures whether a viewer's brain stays engaged.

Test Your Veo AdsYes. Upload the Veo video 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 on media.
Score the Veo ad in PreTestAds, paste the AI Report into Gemini along with the video, and ask it to diagnose the weak moments and rewrite the Veo prompt. Regenerate and re-score. Each tool feeds the next, so the loop runs in minutes.
Yes — a spoken line can carry the hook while the visual stops the scroll, and mistimed audio is a common failure in generated ads. Testing catches pacing problems like a voice line that starts after attention has already dropped.
