Overview

Omni Flash generates cinematic video from text, images or audio, synthesising dialogue and sound natively in the same render rather than adding them afterwards. Character appearance locks across shots, most previews return in under a minute, and refinement happens conversationally rather than by re-prompting from scratch. Commercial rights are included on every plan.

Generating audio in the same pass as the picture is the technically interesting part. Dubbing generated video is a synchronisation problem that never fully resolves – lip movement was produced without knowing the words, so the audio is always fitted to footage that was not made for it. Producing both together means the mouth and the line come from the same decision.

Plans are Lite at $14.90 a month, Pro at $24.90 and Ultra at $49.90, each about half a stated list price, for 600, 1,500 and 4,400 credits, working out between about one and two and a half cents a credit. Two cautions. The site advertises 4K while the output specification says 1080p, and those cannot both be current. And no affiliation with any major model provider is claimed on the page or asserted here, despite what third-party write-ups of this product suggest – it is an independent product until its own site says otherwise.
