AI virtual actors for video ads. Cast once. Ship forever.

A single on-camera talent day is $1,500–$5,000 before you add a crew, an edit, wardrobe or a re-shoot when the hook doesn't land. Multiply that by the 15–30 creative variants a real paid-social account needs per month and the numbers stop working — most brands ship 3 ads a quarter and wonder why performance is flat.

AI virtual actors invert the cost curve. The same synthetic persona renders 30 variants in an afternoon at credit cost. You test more hooks, ship more variants, and let the platform tell you which face-and-hook combination wins — instead of betting the quarter on one casting call.

Most AI actor tools hand you a pre-built library — the same 40 synthetic faces every advertiser on the platform is already running. That's fine for a test but it means your brand character isn't a character; it's a stock model.

Synexa lets you generate and lock your own virtual actor. Face, hair, wardrobe, lighting — all fixed at the avatar level, all exclusive to your account. The persona becomes a recognisable brand asset the way a mascot or a founder does, except it scales to every language, market and variant you'll ever need.

Every clip renders in the formats that actually run: vertical 9:16 for TikTok, Reels, Shorts and Stories; square 1:1 for Meta feed; 16:9 for YouTube pre-roll. 5- or 10-second durations — the length short-form ads live at — with native 4K delivery and no watermark on paid packs.

Talking-head hooks, product demos, lifestyle b-roll and cinematic brand films are all handled by the same locked persona. You're not stitching a stock actor into a template; you're directing a synthetic cast member who already knows the brand.

Paid packs include a full commercial license across every major paid channel — Meta, TikTok, YouTube, Google, Snap. Because the persona is generated, there's no real person's likeness in the frame: no talent release, no usage window, no residuals, no risk of a talent going viral for something you'd rather not be associated with.

For agencies, that means the same virtual actor can carry a client across a 12-month contract without a single re-negotiation. For in-house teams, it means the cast list is yours forever.

Start in the image tool — generate a still that nails the face, wardrobe and vibe of the character you want. Lock the look. From that single frame, every subsequent video, hook and cutdown will use the same persona. When you're ready to test a second character for a different audience, generate a second locked avatar — most brands run a roster of 3–5.

Then write your hook list. 20 hooks in a doc, one avatar locked, 20 clips rendered in an afternoon. Push them all to the platform, let the auction pick a winner, scale the winning combination.
