AI Video Generator by RenderFlow AI

AI Video Generator by RenderFlow AI is a generative video tool. A multi-model video workspace that sends a prompt or a still image to MiniMax H3, Seedance 2.0, Wan 2.7 or Kling 3.0, with per-second credit pricing, aspect ratio options, seed control and native audio on several models.

RenderFlow AI's video generator is a single workspace that routes a prompt or a starting image into one of four model families: MiniMax H3, ByteDance Seedance 2.0, Alibaba Wan 2.7 and Kuaishou Kling 3.0. Each family is offered in text to video and image to video variants, so seven options sit behind the same form. MiniMax and Wan take a first frame and an optional last frame, which suits teams that need a shot to start and end on specific visuals. Seedance adds reference images and web search on top of its prompt, and pushes output as high as 4K. The practical difference between the models is duration, resolution, native audio and credit cost, and the site lays all four out in a comparison table. MiniMax H3 runs 5 to 15 seconds at 480p or 768p with native stereo audio, billed at 4 credits per second at the lower resolution and 8 at the higher one. Wan 2.7 goes to 1080p and longer clips, with audio guidance and prompt expansion, from 20 credits for 2 seconds. Seedance 2.0 starts at 40 credits for 4 seconds; Kling 3.0 starts at 34 credits for 3 seconds on text and 42 on image animation. Aspect ratios cover 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 and 9:21, and a seed value keeps experiments repeatable. The tool is built for people who already know the shot they want: marketers producing product reveals and social ads, illustrators animating a still, concept artists blocking out storyboards, editors filling gaps with B-roll. Three example prompts are provided on the page, from a mountain lake establishing shot to a night intersection, and each model family has its own sample gallery with full prompts attached. Those examples are the most useful part of the page for calibration, since they show how much shot structure a prompt needs before the output holds together. Compared with committing to a single model vendor, RenderFlow's value is side by side access and a shared credit balance. The tradeoff is that quality is whatever the underlying model delivers on a given day, and the price ladder rewards short, low resolution drafts over finished footage.
