Ad Multiplier

A team with a short product ad might want to try a different setting without rewriting the voiceover. Ad Multiplier offers that workflow: upload a 4–30 second video, choose changes to the synthetic presenter, outfit, location or product, and keep the original audio if wanted. Reference photos and written directions give the generator more context.

The public form allows up to four versions and lists 720p and 1080p output. Its stated goal is to retain the source clip’s motion and timing while changing the visuals. That is a useful constraint for comparing creative ideas, but it does not mean an ad’s performance will carry over. The site labels its examples as still-frame illustrations made with an image model; ProjectRadar did not generate a video.

At the listed single-unit price, a 4–15 second version at 720p costs $9.90. A short 1080p version or a 16–30 second 720p version uses two units; a long 1080p version uses four. Packs reduce the unit price, and there is no subscription.

The terms say failed or declined generations return their units to the account balance. That is different from a card refund: unused units from a purchase can be refunded on request within 14 days. A finished version can still contain visual errors or miss a direction, so budget for judging the output before placing an ad.

The service requires rights to the footage and consent from identifiable people in it. Its terms prohibit impersonation, sexual content and depictions of minors. A synthetic replacement presenter does not remove those responsibilities, or the need to check advertising claims and AI-disclosure rules.

According to the privacy policy, source clips, reference photos and directions go to BytePlus ModelArk for generation. Uploads and results are stored for 30 days, with earlier deletion available on request. Download finished work within that window rather than treating the account as an ad archive.
