Vidnix

Vidnix is a generative video tool that animates a still photo with your choice of AI video models. Vidnix is a web-based image to video generator that animates photos using a catalog of AI models such as Wan, Seedance, Veo 3.1 Fast and its own Vidnix Video V3, with prompt-driven motion, audio and credit-based pricing.

Vidnix is a browser-based image to video generator that turns a still picture into a short animated clip. The user uploads a photo, artwork, portrait or product shot, writes a motion prompt, and the platform renders a video. Its main distinction is that it works as a front end to many video models in one place, including its own Vidnix Video V3 and V2 alongside Wan, Seedance, Veo 3.1 Fast, Vidu, Kling, HaiLuo, Skyreels, LTX and others, so the same image can be tried against different engines. In practice the workflow is short. Images are accepted as JPEG, PNG or WebP up to 10MB. The control panel exposes clip duration (5 seconds shown by default), aspect ratio (adaptive, 16:9, 9:16, 1:1, 4:3, 3:4), resolution from 480P to 1080P, an optional seed and an audio toggle. Some modes go further than a single image: first-frame and last-frame inputs, multiple reference images, and reference videos or audio tracks. A prompt translation helper and an AI prompt writer are included for people who do not want to compose motion instructions themselves. Each generation costs credits, and the interface shows the cost before rendering (110 credits for the Vidnix Video V3 settings displayed). The intended audience is practical rather than technical: social media creators making Reels, TikTok and Shorts clips, marketers and ad agencies converting product photos into ecommerce or landing page videos, photographers animating portraits and wedding images, and artists or filmmakers previewing shots from concept art. The site states that output can be used commercially, depending on plan and usage rights. Among alternatives, Vidnix competes less on a proprietary model and more on breadth and convenience. Single-model tools such as Runway or Kling offer deeper control inside one engine, while Vidnix suits people who want to compare several engines and price tiers from one credit balance. New accounts are offered free credits, with paid plans listed on the pricing page for faster rendering and access to premium models.
