AI for Short Ad and Product Videos (October 2026)

OpenAI discontinued Sora in 2026, so most US marketers now build short ads with Google Veo 3.1, Kling or Runway. Clips are still short (often 5 to 10 seconds), so a good ad is several generated shots stitched together with real product footage, captions and sound.

Workflow

Script in shotsWrite a 15 to 30 second script as 3 to 6 shots: hook, problem, product in use, proof, offer. Ask a chat assistant to tighten the hook to the first two seconds.
Generate each shotMake each shot as its own clip in Veo 3.1 or Kling, using a real product photo as the reference image so packaging and color stay accurate.
Mix in real footageUse actual product footage for close-ups, labels and anything a customer will judge the purchase on. AI clips work best for mood and setting.
Edit and captionAssemble in Flow, Runway or your usual editor. Add captions, since many people watch muted, and export 9:16 for Reels, TikTok and Shorts plus a 16:9 or 1:1 cut.
Disclose and publishMark AI-generated assets where ad platforms ask, and add a conspicuous disclosure if a synthetic person appears in an ad running in New York.

Combinations that work

Combination	Why
Veo 3.1 + real product B-roll	Veo handles scenes and sound; real footage keeps product claims honest.
Kling free tier + Runway editing	Explore cheaply with Kling, then refine the keepers in Runway.
HeyGen spokesperson + localized dubbing	One script can become English and Spanish versions without reshooting.

Limits to keep

Sora is no longer available (app and API discontinued in 2026). Move old Sora workflows to another tool.
New York requires a conspicuous disclosure for ads that use an AI-generated synthetic performer, effective 2026-06-09. Audio-only ads and translation-only uses are exempt.
An AI avatar presented as a real customer can be a fake testimonial under the FTC's 2024 rule. Do not imply real experience that did not happen.
Do not use real people's faces or voices, or copyrighted music, without permission. Video pricing is credit-based and changes often.
